|
pedicel |
< stalk |
STRUCTURE |
|
The stalk, when present, of a single flower, except when the flower is solitary and deemed to represent an evolutionarily reduced compound inflorescence borne directly upon a peduncle. |
|
cotyledon |
= seed leaf |
STRUCTURE |
|
Any of the one or more primary foliar structures of an embryonic seed plant, proximal to all succeeding leaf primordia; sometimes serving as a storage organ for food reserves in the seed, as in peas and beans. |
|
position |
|
CHARACTER |
|
Location or disposition with reference to some dissimilar structure(s) or larger context. The lexicons relating to position and insertion overlap to a great degree, since these two morphological concepts are often inseparable in practice. Also overlaps conceptually with arrangement, habit, orientation, and shape. |
|
reniform 2 |
= kidney-shaped |
solid shape |
|
Thickly elongate and arcuate, circular or compressed-circular in transverse section, each end bluntly rounded; like the generalized shape of a human kidney. |
|
scutate |
= buckler-shaped, scutiform |
solid shape |
|
Relatively thin with opposite broad oblong faces, planate to shallowly concave-convex, sometimes thickened about the periphery such that each face has a marginal rim; like an oblong shield. See also scutellate (platter-shaped, scutelliform), which is not clearly distinct in its application. |
|
follicetum pl. folliceta |
|
STRUCTURE |
|
An aggregate of follicles produced from a single flower with multiple simple pistils. |
|
spiculate |
|
relief |
|
Having small, fine, stiff, acute protrusions that resemble little spikes. See also scabridulous (scabrellate, scabrellous, which is not clearly distinct in its application. |
|
hard |
= indurate(d) |
texture |
|
Yielding only under strong pressure; not deformable without internal structural disruption. See also callose (callous), hard-coated (corticate), hard-stemmed (sclerocaulous). |
|
stylopodium pl. stylopodia |
|
STRUCTURE |
|
A discoid enlargement at the base of the styles; esp. in Apiaceae (Umbelliferae). |
|
inframedial |
|
insertion |
|
Slightly below the middle of the structure in point. |
|
thallus 1 pl. thalli |
|
STRUCTURE |
|
The vegetative portion of a shoot when not differentiated into stem and leaves; esp. in Lemnaceae. |
|
longitudinal 2 |
|
orientation |
|
Parallel to the long axis of the context of reference. |
|
bossed |
= umbonate |
solid shape |
|
Having an umbo. |
|
convolute 3 |
|
vernation |
|
Each rolled laterally and wholly surrounded by and/or surrounding the one(s) next adjacent. |
|
pliant |
= flexible, pliable, supple |
texture |
|
Able to bend over its length and/or breadth without structural disruption. |
|
development |
= ontogeny |
CHARACTER |
|
Mode or pattern of growth and differentiation. |
|
raised |
> prominent, prominulous |
prominence |
|
Protruding above the general level of the surrounding surface. |
|
enzymatic |
|
exudation |
|
Secreting a digestive exoenzyme; in carnivorous plants. |
|
scabrate |
= rough, scabrid, scabridous, scabrous |
relief |
|
Having small, stout, stiff, more or less acute protrusions. |
|
flesh |
|
STRUCTURE |
|
Tissue that is fairly firm and dense, juicy or at least moist, and easily cut. |
|
small-beaked |
= rostellate |
apex |
|
Diminutively beaked (rostrate). |
|
groove |
= colpus, fossula, furrow, sulcus, vallecula |
FEATURE |
|
A longitudinal depression that is relatively shallow and narrow. |
|
stipule |
|
STRUCTURE |
|
Any distinct, relatively diminutive, more or less foliaceous structure inserted on a stem alongside a petiole, or on a petiole near its base, and ontogenetically closely associated with the leaf; usually occurring as one of a pair disposed one to either side of the petiole. |
|
tapered |
= attenuate |
solid shape |
|
Gradually diminishing in width or diameter from one end to the other. |
|
lateral |
|
position |
|
To, toward, at, or upon a side, not apical or basal. |
