Irregularly obovoid with an exterior aspect intermediate between inflated and flaccid; like a closed pouch or bag. |
|
wedge-shaped 2 |
= cuneate, obtriangular |

Inversely triangular; like the outline of the broad lateral face of a wedge, broadest at the apex. See also obdeltate. |

STRUCTURE |
|
An elongate, flattened, hygroscopic enation from a spore, straightening upon desiccation and aiding transport by air; esp. in Equisetaceae. |
|
carpophore 3 |
= columella; < stalk |
STRUCTURE |
|
The stalk supporting a mericarp after dehiscence of a schizocarpic fruit, the central axis of the fruit having split longitudinally to yield two or four such stalks; composed of receptacular and (primarily) gynoecial tissues; esp. in Apiaceae (Umbelliferae). |
|
spotted |
= blotched, maculate |
coloration |
|
Having one or more areas that differ in color from the rest of the surface. See also eyespotted. |
|
poricidal |
|
dehiscence |
|
Forming one or more apertures in the exterior wall, usually apically or sub-apically, through which the contents pass to the outside. |
|
…lobed |
? …cleft, …fid, …lobate, …parted, …partite, …segmented |
plane shape |
|
Having the number of lobes indicated by the prefix; as in five-lobed. |
|
tuft |
> coma |
STRUCTURE |
|
A distinct, compact, relatively dense, homogeneous aggregation of plants or constituent structures such as stems, branches, leaves, bracts or trichomes. |
|
aromatic |
|
odor |
|
Having a distinct odor; usually restricted to pleasant odors. |
|
cochleate |
= snail-shell-shaped |
solid shape |
|
Relatively broad and short, basically round in transverse section, resembling a rapidly tapering spire overall, the exterior helically convoluted; like a snail shell. |
|
hyphodromous |
= one-veined, single-veined |
venation |
|
Having one median, primary vein and no other venation externally evident. |
|
style |
|
STRUCTURE |
|
A narrow, usually elongate, ontogenetically distal portion of a simple or compound pistil, overtopping the ovary and bearing one or more stigmas; arising from the summit of the ovary, but sometimes apparently from its base at maturity to ontogenetic displacement from its primordial distal position. In a compound pistil the various simple (carpellary) components of the style(s) may not be connate over their entire lengths; the pistil is then regarded as having a branched style or styles. |
|
radiant 2 |
= radial, radiate, stellate |
arrangement |
|
Disposed about and mutually divergent from a common geometric center in two or three dimensions, thus collectively actinomorphic. |
|
dehiscent |
|
dehiscence |
|
Splitting or forming one or more apertures at maturity, the contents thereby released for dispersal. |
|
vesicle |
|
STRUCTURE |
|
A small bladder-like part consisting of an enclosing wall or covering and an empty or fluid-filled interior, sometimes turgid; esp. in citrus fruits (hesperidia). |
|
gongyloid |
= gongylodate, knob-shaped, knot-shaped, nodiform |
solid shape |
|
Approximately globose, the surface convoluted or not, like a knob or knot; usually applied only to structures or components that are relatively small. |
|
dropper |
= tuberoid |
STRUCTURE |
|
An axial outgrowth that descends from a bulb and eventually forms a new bulb; esp. in Orchidaceae. |
|
obovate |
|
plane shape |
|
Inversely ovate (egg-shaped). |
|
circumcaulous |
|
position |
|
Upon and surrounding the stem. |
|
hirsute |
|
pubescence |
|
Bearing coarse, rough, elongate, more or less erect, capillate trichomes. See also hirtellous. |
|
stipel |
|
STRUCTURE |
|
A stipular analogue subtending a leaflet. |
|
curly |
= crispate, crisped |
margin |
|
Having closely and irregularly spaced, irregularly shaped, often compound convexities that curve irregularly through three dimensions. |
|
megaspore |
= macrospore (not recommended) |
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. |
|
gemma pl. gemmae |
|
STRUCTURE |
|
A vegetative propagule by which a gametophyte reproduces asexually; produced by a process analogous to budding, from a more or less cupulate specialized area (gemmae cup) on the surface of the plant body (thallus); in Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta. |
|
eusporangiate |
|
reproduction |
|
Having relatively large sporangia each of which develops from a group of initial cells that, by periclinal divisions, give rise to an outer layer of primary cells and an inner layer of sporogenous cells; in Psilotophyta, Lycopodiophyta, Equisetophyta, and some Polypodiophyta. |
