microsporocarp |
|
STRUCTURE |
|
A sporocarp that bears only microsporangia. |

|
Hollow, roughly circular in cross-section, broader and open distally, and tapering to a closed apex, like a candle snuffer or elongate hood. |
isthmus |
|
STRUCTURE |
|
A narrower portion connecting two wider or broader portions of an inclusive structure. |
resinous 2 |
|
texture |
|
Having the consistency of resin. |
mucronate |
|
apex |
|
Terminating abruptly in a short, hard point that is a continuation of vascular tissue. See also apiculate, mucronulate. |
crassate |
|
architecture |
|
Relatively thick for the type of structure or in the taxonomic context. |
laevigate 1 |
|
relief |
|
Very smooth. |
eucamptodromous |
|
venation |
|
Having a single median primary vein that branches to either side along the length of the lamina, the secondary veins upwardly arcuate, gradually becoming indistinct interior to the margin, and serially interconnected by cross-branches without formation of marginal loops. |
terete |
|
solid shape |
|
Elongate and transversely round, gradually attenuate from base to apex; attenuate-cylindric or attenuate-tubular, broadest at the base. See also obterete. |
gynodioecious |
|
reproduction |
taxon |
Having some plants with only bisexual flowers and some with only pistillate ones. |
neuter |
|
architecture |
flower, floret |
Lacking both stamens and pistils. |
farina pl. farinae, farinas |
|
SUBSTANCE |
|
A dry, meal- or flour-like covering. |
deciduous 1 |
|
duration |
structure |
Separating and falling away from the bearing axis, organ or plant prior to senescence of the latter, usually by developing an anatomically distinct, transverse, basal zone of cells (abcission layer), where separation occurs. See also seasonally deciduous. |
circumcaulous |
|
position |
|
Upon and surrounding the stem. |
ligule 4 |
|
STRUCTURE |
|
The distal, relatively flat portion of the zygomorphic corolla of a ligulate floret, terminating in 5 teeth or lobes; in Asteraceae (Compositae). |
praemorse |
|
apex |
|
Truncate with the distal margin irregular or ragged, as if chewed. |
banded |
|
coloration |
|
Broadly striped; having one or more elongate, relatively broad and, when multiple, more or less parallel, areas of contrasting hue and/or intensity. |
heterotrophic |
|
nutrition |
plant |
Dependent upon other organisms for some or all of its essential nourishment, assimilating such materials either directly from the other organisms, living or dead, or from their products. |
secund 1 |
|
architecture |
inflorescence |
Having the pedicels oriented such that the main bodies of all the flowers lie to one side of the bearing axis. |
floral |
|
insertion |
|
Upon, within, or associated with the flowers. |
pseudopetiolate |
|
architecture |
leaf |
Having a distinctly constricted, more or less stalk-like, proximal portion that is evolutionarily derived from the blade, the original petiole reduced to the point of absence or vestigiality; esp. in Poaceae (Gramineae). |
collar 1 |
|
STRUCTURE |
|
The free portion (if any) of a floral tube, distal to its casing and/or neck when one or both is/are present. |
