|
See disc. |
|
reticulate 3 |

relief |
|
Having prominulous, more or less regularly interconnected lines. |
|
seed leaf |
= cotyledon |
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. |
|
fragrant |
|
odor |
|
Sweet or otherwise pleasant. |
|
spinose 3 |
= aculeate, spiny |
margin |
|
Having slender, stiff, sharp projections oriented in the general plane of the structure. See also spinulose. |
|
headless 1 |
= acephalous |
architecture |
|
Not terminated or surmounted by a head-like structure, esp. when one might be expected. |
|
intercostal |
|
insertion |
|
Between the costae. |
|
…valleculate |
= …colpate, …fossulate, …furrowed, …grooved, …sulcate |
architecture |
|
Having the number of valleculae indicated by the prefix; esp. fruits of Apiaceae (Umbelliferae); as in tetravalleculate, 8-valleculate. |
|
aculeate |
= spinose, spiny |
margin |
|
Having slender, stiff, sharp projections oriented in the general plane of the structure. |
|
aril 1 (broad sense) |
> arillode, arillus |
STRUCTURE |
|
An appendicular structure that wholly or partly envelops a seed and is produced from or a modification of the funicle, raphe, outer integument, or (in some Pinophyta) a subtending involucre; usually fleshy or pulpy, sometimes spongy or tufted-capillate, often brightly colored. |
|
macrospore (not recommended) |
= megaspore |
STRUCTURE |
|
A female spore; a spore of the larger of two types produced by the sporophytes of a heterosporous taxon; produced in a megasporangium; giving rise upon germination to a megagametophyte. |
|
bractlet 1 |
= bracteole; < bract |
STRUCTURE |
|
A diminutive bract, or a bract that is smaller than others present. |
|
nodose |
= knobby, knotty |
solid shape |
|
Having nodiform (gongylodate, gongyloid, knob-shaped, knot-shaped) protrusions. See also nodulose. |
|
chamber (not recommended) |
= cell (not recommended), locule |
FEATURE |
|
Any structurally distinct compartment within an anther, ovary, fruit or other organ; not necessarily having any evolutionary integrity. |
|
paraphysis pl. paraphyses |
|
STRUCTURE |
|
An elongate, multicellular, sterile structure borne between sporangia within a sorus; in Polypodiophyta. |
|
corolla pl. corollae, corollas |
|
STRUCTURE |
|
Collectively, the petals of a flower, whether distinct or connate; the inner or distal envelope of a differentiated perianth, whether the other envelope (calyx) is actually present or is deemed to be absent due to evolutionary reduction. |
