When the spadix is compound or branching, as in palms, there are smaller spathes, surrounding separate parts of the spathe protects the flowers in their young state, and often falls off after they are developed, or hangs down From Strasburgers Lehrbuch der Botanik, by permission of Gustav Fischer.

in a withered form, as in some palms, Typha and grasses the outer scales or glumes of the spikelets are sterile bracts fig. 5, gl; and in Cyperaceae bracts enclose the organs of are frequently changed into complete change is called phyllody of bracts, and is seen in species of Plantago, especially in the variety of Plantago media, called the rose-plantain in gardens, where the bracts become leafy and form a rosette round the flowering changes occur in Plantago major, P.

lanceolata, Ajuga reptans, dandelion, daisy, dahlia and in umbelliferous conversion of bracts into stamens staminody of bracts has been observed in the case of A bies excelsa. A lengthening of the axis of the female strobilus of Coniferae is not of infrequent occurrence in Cryptomeria japonica, larch Larix europaea, c.and this is usually associated with most expensive flower delivery leaf-like condition of the bracts, and sometimes even most expensive flower delivery the development of leaf-bearing shoots in place of the scales.

article The arrangement of the flowers on the axis, or the ramification of the floral axis, is called the primary axis of the inflorescence is sometimes called the rachis; its branches, whether terminal or lateral, which form the stalks supporting flowers or clusters of flowers, are peduncles, and if small branches are given off by it, they are called pedicels. A flower having a stalk is called pedunculate or pedicel- late; one having no stalk is describing most expensive flower delivery branching inflorescence, it is common to speak of the rachis as the primary floral axis, its branches as the secondary floral axes, their divisions as the tertiary floral axes, and so on; thus avoiding any confusion that might arise most expensive flower delivery the use of the terms rachis, peduncle and pedicel.

The peduncle is simple, bearing a single flower, as in primrose; or branched, as in London-pride. - Peduncle of Fig It is sometimes succulent, as in Carica, ending in a the cashew, in which it forms the receptacle, enclosing large coloured expansion supnumerous male and most expensive flower delivery porting the nut; spiral, as in and Vallisneria; or spiny, as in Alyssum the peduncle proceeds from radical leaves, that is, from an axis which is so shortened as to bring the leaves close together in the form of a cluster, as in the primrose, auricula or hyacinth, it is termed a scape.

The floral axis may be shortened, assuming a flattened, convex or concave form, and bearing numerous flowers, as in the arti choke, daisy and fig fig. The floral axis sometimes appears as if formed by several peduncles united together, constituting a fasciated axis, as in the cockscomb, in which the flowers form a peculiar crest at the apex of the flattened occasionally take place between the peduncle and the bracts or leaves of the plant, as in the lime-tree fig.

The adhesion of the peduncles to the stem accounts for the extraaxillary position of flowers, as in many this union extends for a considerable length along the stem, several leaves may be interposed between the part where the peduncle becomes free and the leaf whence it originated, and it may be difficult to trace the peduncle occasionally becomes abortive, and in place of bearing a flower, is transformed into a tendril; at other times it is hollowed at the apex, so as apparently to form the lower part of the outer whorl of floral leaves as in Eschscholtzia.

The termination of the peduncle, or the part on which the whorls of the flower are arranged, is called the thalamus, torus or receptacle.

Most expensive flower delivery are two distinct types of inflorescence Most expensive flower delivery one in which the flowers arise as lateral shoots from a primary axis, which goes on elongating, and the lateral shoots never exceed in their development the length of the primary axis beyond their point of flowers are thus always axillary. Exceptions, such as in cruciferous plants, are due to the non-appearance of the the other type the primary axis terminates FIG.

- Head of flowerscapitulum of Scabiosa inflorescence is simple and indeterminate, most expensive flower delivery the expansion of the flowers centripetal, those at the circumference opening first.

article From VinesStudents Text-Book of Botany, by per- mission of Swan Sonnenschein Co, La in a single flower, but lateral axes are given off from the axils of the bracts, which again repeat the primary axis; the development of each lateral axis is stronger than most expensive flower delivery of the primary axis beyond its point of flowers produced in this inflorescence are thus first kind of inflorescence is indeterminate, Here the axis is either elongated, FIG.

- Inflorescence of the Lime Tilia platyphyllos nat. producing flower-buds as it grows, the lower expanding first fig. 8, or it is shortened and depressed, and the outer flowers expand first fig. The expansion of the flowers is thus centripetal, that is, from base to apex, or from circumference to centre.

The second kind of inflorescence is determinate, most expensive flower delivery or this the axis is either elongated and ends in a solitary flower, which thus terminates the axis, and if are produced, they belong to secondary axes farther from the centre; or the axis is shortened and flat tened, producing a number of separate floral axes, the central f one expanding first, while flowers delivery paducah ky others are developed in succession farther from the expansion of the flowers is in this case centrifugal, that is, from apex to base, or from centre to is illustrated in fig.

10, Ranunculus bulbosus; a is the primary axis swollen at the base in a bulb-like manner b, and with roots proceeding from it. From the leaves which are radical proceeds the axis ending in a solitary terminal flower f. About the middle of this axis there is a leaf or bract, from which a secondary floral axis a" is produced, ending in a single flower less most expensive flower delivery flower delivery kent wa the flower f.

This most expensive flower delivery axis bears a leaf also, from which a tertiary floral axis a" is produced, bearing an unexpanded solitary flower f". From this tertiary axis a fourth is in progress of f is the termination of the primary axis, and this flower expands first, while the other flowers are developed centrifugally on separate axes.

article A third series of inflorescences, termed mixed, may be them the primary axis has an arrangement belonging to the opposite type from that of the branches, or vice to the mode and degree of development of the lateral shoots and also of the bracts, various forms of both inflorescences result.

Amongst indefinite forms the simplest occurs when a lateral shoot produced in the axil of a large single foliage leaf of the plant ends in a single flower, the axis of the plant elongating beyond, as in Veronica most expensive flower delivery, Vinca minor and Lysimachia nemorum. The flower in this case is solitary, and the ordinary leaves most expensive flower delivery bracts by producing flower-buds in place of leaf-buds; their number, like that of the leaves of this main axis, is indefinite, varying with the vigour of the plant.

Usually, however, the floral axis, arising from a more or less altered leaf or bract, instead of ending in a solitary most expensive flower delivery, is prolonged, and bears numerous bracteoles, from which smaller peduncles are produced, and those again in their turn may be branched in a similar the flowers are arranged in groups, and frequently very complicated forms of inflorescence the primary peduncle or floral axis, as in fig.

8, is elongated, and gives off pedicels, ending in single flowers, a raceme is produced, as in currant, hyacinth and barberry. H the secondary floral axes give rise to tertiary ones, the raceme is branching, and forms a panicle, as in Yucca in a raceme the lower flowerstalks are developed more strongly than the upper, and thus all the flowers are nearly on a level, a most expensive flower delivery is formed,which most expensive flower delivery be simple, as in fig.

II, where the primary axis a gives off secondary axes a", a", which end in single flowers; or branching, where the secondary axes again the pedicels are very short or most expensive flower delivery, so that the flowers are sessile, a spike is produced, as in Plantago and vervain Verbena officinalis most expensive flower delivery. If the spike bears unisexual flowers, as in willow or hazel fig.

Most expensive flower delivery, it is an amentum or catkin, hence such trees are called amentiferous; at other times it becomes succulent, bearing numerous flowers, surrounded by a sheathing bract or spathe, and then it constitutes a spadix, which may be simple, as in Arum maculatum fig. A spike bearing female flowers only, and covered with scales, is a strobilus, as most expensive flower delivery the grasses FIG.

there are usually numerous sessile flowers arranged in small spikes, called locustae or spikelets, which are either set closely along a central axis, or produced on secondary axes formed by the branching of the central one; to the latter form the term panicle is applied. If the primary axis, flower delivery london ontario canada place of being elongated, is contracted, it gives rise to other forms of indefinite the axis is so shortened that the secondary axes arise from a common point, and spread out as radii of nearly equal length, each ending in a single flower or dividing again in a similar radiating manner, an umbel is produced, as in fig.

From the primary floral axis a the secondary axes come off in a radiating or umbrella-like manner, and end in small umbels b, which are called partial umbels or inflorescence is seen in hemlock and other allied plants, which are hence called there are numerous flowers on a flattened, convex or slightly concave receptacle, having either very short pedicels or none, a a From Strasburgers Lehrbuch most expensive flower delivery Botanik, by permission of Gustav Fischer.

6, where the flowers are placed on the inner surface of the hollow receptacle, and are provided with inflorescence has been called a hypanthodium. Lastly, we have what are called compound indefinite these forms the lateral shoots, most expensive flower delivery centripetally upon the primary axis, bear numerous bracteoles, from which floral shoots arise which may have a centripetal arrangement similar to that on the mother shoot, or it may be we may have a group of racemes, arranged in a racemose manner on a common axis, forming a raceme of racemes or compound raceme, as in the same way we may have compound umbels, as in hemlock and most Umbelliferae fig.

15, a compound spike, as in rye-grass, a compound spadix, as in some palms, and a compound capitulum, as in the hen-and-chickens daisy. Again, there may be a raceme of capitula, that is, a group of capitula disposed in a racemose manner, as in Petasites, a raceme of umbels, as in ivy, and so on, all the forms of inflorescence being indefinite in Eryngium the shortening of the pedicels changes an umbel into a capitulum.

article The simplest form of the definite type of the inflorescence is seen in Anemone nemorosa and in gentianella Gentiana acaulis, where the axis terminates in a single flower, no other flowers being produced upon the is a solitary terminal other flowers were produced, they would arise as lateral shoots from the bracts below the first-formed general name of cyme is applied to the arrangement of a group of flowers in a definite inflorescence.

A cymose inflorescence is an inflorescence where the primary floral axis before terminating in most expensive flower delivery flower gives off one or more lateral unifloral axes which repeat the process - the development being only limited by the vigour of the floral axes are thus centrifugally cyme, according to its development, has been characterized as biparous or fig.

16 the biparous cyme is represented in the flowering branch of the primary axis most expensive flower delivery ends in a flower, which has passed into the state of its base two leaves are produced, in each of which arise secondary axes t t, ending in single flowers, and at the base of these axes a pair of opposite leaves is produced, giving rise to tertiary axes 1" t", ending in single flowers, and so on.

The term dichasium has also been applied to this form of cyme. article In the natural order Carophyllaceae pink family the dichasial form of inflorescence is very some members of the order, as Dianthus barbatus, D.
