transverse 1 |
|
dehiscence |
|
More or less perpendicular to the central axis. |
connective |
|
STRUCTURE |
|
The tissue between and joining the laterally opposed thecae of an anther, connecting them with the distal end of the staminal filament when the latter is present. |
equitant |
|
arrangement |
|
Alternate, distichous, basal, and congested, each conduplicate with its lateral edges overlapping and/or overlapped by those of the immediately adjacent one(s). |
ciliate |
|
margin |
|
Having fine, hair-like trichomes (cilia) oriented in the general plane of the structure. |
laciniate |
= slashed; < cut, incised, lacerate, torn |
plane shape |
|
Having relatively close, more or less straight lines of separation exending inward from the margin. See also cleft (dissected, divided, lobate, lobed, parted, partite, segmented). |
trulliform |
= trowel-shaped, trullate |
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. |
reduced |
|
size |
|
Unusually or unexpectedly small. |
involucre 1 |
|
STRUCTURE |
|
One or more closely proximate whorls, or a compact spiral, of bracts immediately subtending an inflorescence, the bracts sometimes leaf-like, sometimes petaloid. |
chaff 1 |
|
STRUCTURE |
|
Collectively, the paleae (pales, palets) sometimes borne on the receptacle of a capitulum (head) in Asteraceae (Compositae). |
setiform |
= bristle-shaped, setaceous |
solid shape |
|
Elongate, slender, terete, straight, terminating in a fine point, and apparently stiff; like a bristle. |
fertile frond |
< spore leaf, sporophyll |
STRUCTURE |
|
A frond that bears sporangia; in Polypodiophyta. See also sterile frond (trophophyll). |
placenta-shaped |
= placentiform |
solid shape |
|
Thickly discoid (disciform); like the generalized form of a human placenta. |
locule |
= cell (not recommended), chamber (not recommended) |
FEATURE |
|
Any structurally distinct compartment within an anther, ovary, fruit, sporangium or other organ; not necessarily having any evolutionary integrity. |
pseudolamina pl. pseudolaminae |
|
STRUCTURE |
|
The expanded part of a phyllode (phyllodium), resembling a blade but evolutionarily derived from the petiole. |
glochidium pl. glochidia |
= glochid; < bristle, capillus, hair, seta, trichome |
STRUCTURE |
|
A capillus (hair) or bristle (seta) that bears one or more barbs; esp. in Cactaceae. |
squamella 1 pl. squamellae |
= squamule; < scale, trichome |
STRUCTURE |
|
A diminutive squama (lepis). |
three-… |
= tri… |
prefix |
|
Indicating presence of or constitution by three entities of the type denoted by the term's stem; as in three-cleft, three-flowered, three-ranked. See also thrice… (tri…, triple…). |
entire |
|
margin |
|
Uninterrupted; not deviating significantly from its general line, thus lacking any localized convexities or concavities. |
parietal |
|
placentation |
|
Upon the inner wall surface of a unilocular ovary, thus peripheral within the locule. |
napiform |
= turnip-shaped |
solid shape |
|
Depressed-globose overall and strongly acuminate (concave-tapered) at the base; like the generalized form of a turnip. |
infrafoliar |
|
position |
|
Upon the stem directly below a leaf insertion. |
cartilage-like |
= cartilaginous |
texture |
|
Firm, dense, tough, somewhat pliable, and resilient, like human cartilage. |
extrafloral |
|
position |
|
Outside and proximal to the flower; esp. nectaries. |
nodal |
> interpetiolar |
position |
|
Upon or associated with the nodes. |
spinose 1 |
|
apex |
|
Terminating in a rigid, tapering, sharp continuation of the central primary vein. See also spinulose. |
