|
The portion of the corolla of a bisexual or staminate disc floret distal to the level of filament insertion; in Asteraceae (Compositae). |
trullate |
= trowel-shaped, trulliform |
plane shape |
|
Broadest below the middle, more or less straightly attenuate to either end, the sides angled at the level of greatest width; like the blade of a mason's trowel. See also obtrullate, obtrulliform. |
rounded |
|
base |
|
Convex overall and more or less regularly curved. |
floccose |

pubescence |
|
Bearing tufts of soft, fine, capillate trichomes that rub off easily. |
obvolute 2 |
|
vernation |
|
Conduplicate with the lateral edges of each leaf alternately overlapping those of the oppositely oriented, distally next adjacent one. |
hood |
= cucullus |
STRUCTURE |
|
A hood-shaped structure or component, esp. in an inflorescence or flower. |
stomium pl. stomia |
= stomatal pore |
FEATURE |
|
The opening in the wall of a sporangium, between the lip cells, through which the spores exit; in Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta. |
putrid |
= fetid |
odor |
|
Stinking like rotting flesh. |
…cleft |
? …fid, …lobate, …lobed, …parted, …partite, …segmented |
solid shape |
|
Having the number of lobes, divisions or segments indicated by the prefix; as in three-cleft. |
microphyll |
|
STRUCTURE |
|
A small, lateral, leaf-like enation that, evolutionarily, is not a true leaf, i.e., whose vasculature, if any, consists of only a single median strand not ontogenetically integral with the vasculature of the bearing stem and not associated with leaf gaps in the stele of the stem; in Bryophyta, Psilotophyta, Lycopodiophyta, Equisetophyta. |
veined |
|
architecture |
|
Having one or more orders of evident vasculature. |
glaucescent |
< ceraceous, cereous, pruinose, waxen, waxy |
coating |
|
Becoming glaucous with age. See also caesious. |
spadix pl. spadices |
|
STRUCTURE |
|
A thick, fleshy, primary inflorescence axis bearing sessile flowers more or less sunken into its surface, the whole subtended and sometimes partially enclosed by a specialized bract, the spathe; esp. in Araceae. |
…parted |
? …cleft, …fid, …lobate, …lobed, …partite, …segmented |
solid shape |
|
Having the number of lobes, divisions or segments indicated by the prefix; as in five-parted. |
involucel |
|
STRUCTURE |
|
One or more closely proximate whorls of bractlets (bracteoles, prophylls) immediately subtending (below or outside) a subordinate portion of an inflorescence that is subtended as a whole by an involucre, the bractlets often leaf-like, sometimes petaloid. |
ribbed 1 |
= costate |
architecture |
|
Having one or more ribs (costae). |
crassate |
|
architecture |
|
Relatively thick for the type of structure or in the taxonomic context. |
nutrition |
|
CHARACTER |
|
Mode of acquiring nutrients. |
herbaceous 2 |
|
texture |
|
Composed entirely of relatively soft, non-woody (unlignified) tissues derived from primary growth. |
stem |
> cane, culm |
STRUCTURE |
|
The entire axial system of a shoot, or a component, primary or higher-order (branch) axis of the shoot; differentiated anatomically and morphologically into nodes and internodes, from the former of which it branches exogenously and bears leaves, bracts, and/or inflorescences; usually growing above ground level, but sometimes structurally and functionally specialized and growing underground (e.g., rhizome, tuber) or upon the surface of the ground (e.g., stolon). Although sometimes phenotypically distinctive and often treated separately for descriptive purposes, the axial system of an inflorescence, excluding pedicels or parts of them in some cases, is properly stem in the above general sense. |
pseudobulb |
|
STRUCTURE |
|
An enlarged internode of an aboveground stem, storing water and photosynthate, resembling a bulb; esp. in Orchidaceae. |
lemma pl. lemmata, lemmas |
|
STRUCTURE |
|
The proximal bract of the (usually) two that immediately subtend the flower in a grass (Poaceae) floret; the other is the palea. |
trabeculate |
< septate |
architecture |
|
Having one or more trabeculae. |
pseudolamina pl. pseudolaminae |
|
STRUCTURE |
|
The expanded part of a phyllode (phyllodium), resembling a blade but evolutionarily derived from the petiole. |
lens-shaped 1 |
= biconvex, lenticular |
plane shape |
|
Elongate, narrow, broadest at the middle, attenuate to acute ends, the sides convex; like the outline of a couble-convex lens viewed from its edge. |
