neuter |
|
architecture |
flower, floret |
Lacking both stamens and pistils. |
bulbel |
|
STRUCTURE |
|
A comparatively small bulb branching laterally from a larger, currently primary one. |
continuous 1 |
|
architecture |
inflorescence |
Having the flowers or branch units distributed evenly along the axis, with no significant interruption. |
prop root |
|
STRUCTURE |
|
A relatively stout adventitious root arising from the lower portion of a main stem and extending outward and downward toward the substrate, within which it ultimately becomes anchored, thus buttressing the aboveground portion of the plant. |
herbaceous 2 |
|
texture |
|
Composed entirely of relatively soft, non-woody (unlignified) tissues derived from primary growth. |
equatorial ridge |
|
FEATURE |
|
A circumferential ring about a megaspore in the plane of its equator, raised above the remainder of the wall surface; in some heterosporous taxa of Polypodiophyta. |
pseudobulb |
|
STRUCTURE |
|
An enlarged internode of an aboveground stem, storing water and photosynthate, resembling a bulb; esp. in Orchidaceae. |
rounded |
|
base |
|
Convex overall and more or less regularly curved. |
pyramidal |
|
solid shape |
|
Transversely triangular or polygonal, broadest at the base and regularly attenuate to an angular apex, all faces essentially plane. |
pallid |
|
coloration |
|
Relatively pale; not strongly colored. |
alete |
|
architecture |
spore |
Lacking a tetrad scar (surficial ridge or angle resulting from coherence with others produced from the same spore mother cell). |
seed |
|
STRUCTURE |
|
A mature or ripened ovule containing an embryonic sporophyte and a nutritive tissue (endosperm or perisperm) with stored food that sustains the initial growth of the embryo upon germination, except when such food reserve is stored instead in the cotyledon(s) of the embryo itself, these enclosed by one or two integuments (the testa), the whole serving as a propagule. A fertile seed (one containing a viable embryo) normally results from sexual fertilization of an egg by a sperm; however, fertile seeds are sometimes produced asexually by apomictic processes (e.g., parthenogenesis). |
simple-craspedodromous |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins and their branches all running toward and terminating at the margin. |
cotyloid |
|
architecture |
flower |
Having general adnation among the different sets of floral structures, thus having the ovary inferior and/or having a floral tube. |
anther |
|
STRUCTURE |
|
The fertile, loculate, pollen-bearing portion of a stamen, containing one, two, or four thecae (pollen sacs), when that portion is differentiated from and borne at the summit of a narrower supporting stalk (filament), or when such differentiation is deemed to have occurred in the evolutionary past with subsequent reduction of the filament (the anther then sessile and constituting the entirety of the stamen). |
beard |
|
STRUCTURE |
|
A growth of relatively long, erect, flexible, capillary trichomes from one or more limited sectors of a structure's surface. |
cloying |
|
odor |
|
Sickeningly sweet. |
andropetalous 1 |
|
architecture |
flower, androecium |
Having petaloid, sterile stamens. |
subpetiolar |
|
insertion |
|
Just below the point of petiole insertion. |
ellipsoid(al) |
|
solid shape |
|
Elliptic in any median longitudinal section; elongate, transversely circular, broadest at the middle, and symmetrically convex-attenuate to rounded ends. See also oblong. |
spathulate |
|
plane shape |
|
See spatula-shaped, spatulate. |
aquatic |
|
habit |
plant |
Growing in water. |
perforate |
|
architecture |
foliaceous structure |
Having portions of the laminar (blade) area naturally devoid of any tissue. |
comose |
|
pubescence |
|
Bearing a prominent single tuft of relatively long and slender, flexible, capillate trichomes (coma). |
incurved |
|
orientation |
|
Curving adaxially. See also decurved. |
