scaly 2 |
|
architecture |
bud, bulb |
Invested by scale-like (squamiform) structures. |
mottled |
|
coloration |
|
Having one or more indistinctly delineated, irregularly shaped, areas of varying size and contrasting hue and/or intensity. |
exudation |
|
CHARACTER |
|
Discharged substance, as to type. |
beard |
|
STRUCTURE |
|
A growth of relatively long, erect, flexible, capillary trichomes from one or more limited sectors of a structure's surface. |
capsule |
|
nominative |
fruit |
Dry, longitudinally or poricidally dehiscent, and derived from a compound ovary with one or more locules; containing one or more seeds. See also pyxis. |
supervolute |
|
vernation |
|
Each with one side rolled adaxially inward from the margin and enveloped by the abaxially rolled opposite side. |
shoot 1 |
|
STRUCTURE |
|
Collectively, all those portions of a plant body that are anatomically distinct from the root, the component axes differentiated into nodes and internodes, and branching exogenously from the former. |
cochlear |
|
aestivation |
|
Imbricate with one member larger than and exterior to the others, parallel to one that is internal to all the others, strongly incurved, and enclosing the others. |
staminal |
|
insertion |
|
Upon or otherwise directly associated with the stamens. |
sepal |
|
STRUCTURE |
|
One of the one or more constituent members of a calyx; usually green and leaf-like, but sometimes with color and/or texture otherwise, sometimes petaloid; may be distinct or else connate with one or more others and/or may be free or else adnate to one or more other floral structures. |
porosity |
|
CHARACTER |
|
Presence and disposition of vessels (pores) in wood (xylem). |
pericarp |
|
STRUCTURE |
|
The portion of a fruit wall that is derived from the ovary wall; consisting of three more or less distinct tissue layers (exocarp or epicarp, mesocarp, and endocarp) that may or may not differ greatly in structure and/or function; the wall of a fruit, excluding any tissues of extra-ovarian (accessory) origin. |
chaff 1 |
|
STRUCTURE |
|
Collectively, the paleae (pales, palets) sometimes borne on the receptacle of a capitulum (head) in Asteraceae (Compositae). |
grumous |
|
solid shape |
|
Having an external aspect like a cluster of grains, basically convex overall. |
antipetalous |
|
position |
equivalent floral structures |
Each inserted directly above or below a petal. In place of this term, the phrase "opposite the petals" is often used, but that contradicts the sense of opposite as otherwise employed (arrangement of lateral structures along an axis) and should be avoided. |
