Examples of inflorescence in a Sentence
Hardy bulbs of the garlic family, some species of which are ornamental; the inflorescence is umbellate.
Each podium consists of a portion of the stem bearing one or more leaves, each with an axillary bud or buds, and terminating in a tendril or an inflorescence.
The tendril or inflorescence, according to the views above explained, though in reality terminal, is bent to one side; hence it appears to be lateral and opposite to the leaf.
The Monandreae have been subdivided into twenty-eight tribes, the characters of which are based on the structure of the anther and pollinia, the nature of the inflorescence, whether terminal or lateral, the vernation of the leaf and the presence or absence of a joint between blade and sheath, and the nature of the stem.
A flower dissected and gummed on the sheets will often retain the colour which it is impossible to preserve in a crowded inflorescence.
The flowers are arranged in racemes without bracts; during the life of the flower its stalk continues to grow so that the open flowers of an inflorescence stand on a level (that is, are corymbose).

The small inconspicuous flowers are generally more or less crowded in terminal or lateral clusters, the form of the inflorescence varying widely according to the manner of branching and the length of the pedicels.
There are numerous transitional states between the ordinary form of tendril and the inflorescence.
Foliage, tendril and inflorescence, reduced.
This new podium, now in a direct line with its predecessor, produces leaves and ends in its turn in a tendril or inflorescence.
Other authorities explain the formation of the tendril and its anomalous position opposite to a leaf by supposing that the end of the stem bifurcates during growth, one division forming the shoot, the other the tendril or inflorescence.
The small flowers or spikelets are borne in pairs on the ultimate branches of a much branched feathery plume-like terminal grey inflorescence, 2 ft.
The inflorescence is a very simple one, consisting of one or two male flowers each comprising a single stamen, and a female flower comprising a flask-shaped pistil.
These are followed by the inflorescence, a fleshy spadix bearing in the lower part numerous closely crowded simple unisexual flowers and continued above into a purplish or yellowish appendage; the spadix is enveloped by a leafy spathe, constricted in the lower part to form a chamber, in which are the flowers.
The flowers, which are generally arranged in a cymose inflorescence, are hermaphrodite, hypogynous, and, except in Pelargoniums, regular.
Thus the flowers are arranged in groups, and frequently very complicated forms of inflorescence result.
If the primary axis, in place of being elongated, is contracted, it gives rise to other forms of indefinite inflorescence.
The inflorescence in the family Boraginaceae are usually regarded as true scorpioid cymes.
An inflorescence has the form of a dichotomouslybranched cyme bearing small erect cones; those containing the female flowers attain the size of a fir-cone, and are scarlet in colour.
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 plant.
This is a solitary terminal inflorescence.
The 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 a flower gives off one or more lateral unifloral axes which repeat the process - the development being only limited by the vigour of the plant.
When the axes become very much shortened, the arrangement is more complicated in appearance, and the nature of the inflorescence can only be recognized by the order of opening of the flowers.
A characteristic feature is the one-sided (dorsiventral) inflorescence, well illustrated in forget-me-not and other species of Myosotis; the cyme is at first closely coiled, becoming uncoiled as the flowers open.
End of branch of inflorescence slightly enlarged.
Any sudden decrease of warmth would be very prejudicial to the progress of vegetation through the successive stages of foliation, inflorescence and fructification.
They do well in light, well-drained soils, and have a close family resemblance, the inflorescence being a panicle of white, drooping, tulip-shaped flowers, and the foliage rosulate, sword-shaped and spear-pointed.
Cordaites, a tall plant (20-30 ft.) with yucca-like leaves, was related to the cycads and conifers; the catkin-like inflorescence, which bore yew-like berries, is called Cardiocarpus.
Such a branch-system is called an inflorescence.
During the development of the inflorescence there is a rush of sap to the base of the young flowerstalk.
The inflorescence is of a cymose character, the terminal branch being represented by the tendril, the side branches by flower-stalks, or the inflorescence may be reduced to a single stalk.
Bracts of a more general character subtending branches C' of the inflorescence are singularly rare in Gramineae, in marked contrast with Cyperaceae, where they are so conspicuous.
It is closed except at the apex, and contains the female spikelet, the stalks of the male inflorescence and the long styles emerging through the small apical orifice.
Any number of spikelets may compose the inflorescence, and their arrangement is very various.
Every variety of racemose and paniculate inflorescence obtains, and the number of spikelets composing those of the large kinds is often immense.
Rarely the inflorescence consists of very few flowers; thus Lygeum Spartum, the most anomalous of European grasses, has but two or three large uniflorous spikelets, which are fused together at the base, and have no basal glumes, but are enveloped in a large, hooded, spathe-like bract.
Less absolute characters, but generally trustworthy and more easily observed, are the feathery stigmas, the always distichous arrangement of the glumes, the usual absence of more general bracts in the inflorescence, the split leaf-sheaths, and the hollow, cylindrical, jointed culms - some .or all of which are wanting in all Cyperaceae.
No characters for main divisions can be obtained from the flower proper or fruit (with the exception of the character of the hilum), and it has therefore been found necessary to trust to characters derived from the usually less important inflorescence and bracts.
In Setaria and allied genera the spikelet is subtended by an involucre of bristles or spines which represent sterile branches of the inflorescence.
Phleum has a cylindrical spike-like inflorescence; P. pratense (timothy) is a valuable fodder grass, as also is Alopecurus pratensis (foxtail).
Another view is to regard the cone as an inflorescence, each carpellary scale being a bract bearing in its axil a shoot the axis of which has not been developed; the seminiferous scale is believed to represent either a single leaf or a fused pair of leaves belonging to the partially suppressed axillary shoot.
It may be that the interpretation of the female cone of the Abietineae as an inflorescence, which finds favour with many botanists, cannot be applied to the cones of Agathis and Araucaria.
The spike of an inflorescence bears whorls of flowers at each node in the axils of concrescent bracts accompanied by numerous sterile hairs (paraphyses); in a male inflorescence numerous flowers occur at each node, while in a female inflorescence the number of flowers at each node is much smaller.
They are marshor water-plants with generally a stout stem (rhizome) creeping in the mud, radical leaves and a large, much branched inflorescence.
Erysiple graminis, a mildew of grasses, has caused great loss in various countries; Dilophia graminis sometimes causes deformities of the leaves and inflorescence; another somewhat similar fungus, Ophiobolus graminis, attacks the leaves and stalks near the ground, completely destroying the plants.
In general as regards their form and appearance they differ from ordinary leaves, the difference being greater in the upper than in the lower branches of an inflorescence.
