drupelet |
|
nominative |
fruit |
Diminutively drupe-like but derived from one of the simple, superior ovaries of an apocarpous flower, having a fleshy fruit wall and a hard seed (pyrene) within, a distinct constituent in an aggregate fruit; esp. in Rosaceae. |

A second- or higher-order axis of a compound leaf blade, bearing higher-order rachillae, leaflets, pinnules and/or tendrils. |
|
subsidiary cell |
|
STRUCTURE |
|
One of the cytologically distinctive epidermal cells that are sometimes present in a stomate and that surround and are regularly oriented in relation to the guard cells. |
|
connate |
|
fusion |
equivalent structures |
Intimately fused, with strong histological continuity. |
|
interrupted 2 |
|
architecture |
inflorescence |
Having one or more gaps in an otherwise uniform distribution of flowers or branch units along the main axis. |
|
percurrent 1 |
|
architecture |
primary or secondary laminar veins |
Running through the entire length of the lamina (blade), or all the way to its margin. |
|
simple 1 |
|
architecture |
|
Externally unitary and comprising only one basic morphological unit; not compound in either sense of that term. |
|
monadal |
|
arrangement |
pollen |
Shed singly, or essentially so, only loosely and irregularly, if at all, coherent, each original tetrad having separated fully. |
|
spadix pl. spadices |
|
STRUCTURE |
|
A thick, fleshy, primary inflorescence axis bearing sessile flowers more or less sunken into its surface, the whole subtended and sometimes partially enclosed by a specialized bract, the spathe; esp. in Araceae. |
|
epipetalous |
|
insertion |
|
Upon the petals, or partially adnate thereto and apparently arising therefrom. |
|
apetalous |
|
architecture |
flower, perianth |
Lacking petals. |
|
revolute 2 |
|
vernation |
|
Each rolled abaxially inward from the lateral margins. |
|
laminar 2 |
|
solid shape |
|
Relatively very thin with parallel opposite broad faces, the whole plane or variously curved. Structures to which this term, along with any other three-dimensional ones, is applicable are often also described as though only two-dimensional, using terms that are implicitly understood to refer only to the outline of the broad faces. |
|
exfoliating |
|
relief |
bark |
Shallowly and distantly fissured, falling away in thin, relatively large patches or sheets. |
|
rosette |
|
STRUCTURE |
|
A set of leaves that are strongly congested and disposed in radial symmetry about the main stem at or very near its base, seeming to arise at the same level and often overlapping laterally; esp. the overwintering leaves of perennial herbs. |
|
legume |
|
nominative |
fruit |
Dry, septicidal, one-loculed and derived from a single, superior, simple ovary; dehiscing along two sutures, one abaxial, one adaxial; in Fabaceae (Leguminosae). See also loment. |
|
pollinarium pl. pollinaria |
|
STRUCTURE |
|
A pollinium together with, when present, its stipe and viscidium; the entire unit of pollinium dispersal. |
|
obovoid |
|
solid shape |
|
Inversely ovoid (egg-shaped). |
|
lineate 1 |
|
coloration |
|
Having very narrow, straight, clear or colored lines that contrast with the ground color. |
|
stephanoporate |
|
architecture |
pollen grain |
Having more than three pores disposed equatorially. |
|
fissured |
|
relief |
bark |
Split or cracked vertically, diagonally, and/or horizontally in a regular or irregular pattern, the fissures not encircling the stem individually. |
|
barbellate |
|
architecture |
|
Bearing one or more barbels. |
|
scape |
|
STRUCTURE |
|
A leafless, essentially naked, inflorescence-bearing stem (or peduncle) arising directly from a caudex or rhizome, its point of insertion slightly beneath, at, or slightly above the substrate surface. |
