pepo |
|
nominative |
fruit |
Like a berry but derived from a single, inferior, compound ovary, with accessory floral-tube tissue adnate to the pericarp, having a relatively thin, hard or leathery rind and a thicker, fleshy inner wall that surrounds a mass of seeds; esp. in Cucurbitaceae. |
|
supervolute |
|
vernation |
|
Each with one side rolled adaxially inward from the margin and enveloped by the abaxially rolled opposite side. |
|
gelatinous |
|
texture |
|
Jelly-like; soft, moist, continuously cohesive, texturally homogeneous, somewhat resilient, and easily cut. |
|
mixed-craspedodromous |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins running thence toward the margin, some becoming indistinct before reaching it, others terminating there. |
|
corolla tube 2 |
|
STRUCTURE |
|
The portion of the corolla of a bisexual or staminate disc floret proximal to the level of filament insertion; in Asteraceae (Compositae). |
|
petiolar |
|
position |
|
Upon or otherwise directly associated with the petioles. |
|
spadicate |
|
architecture |
inflorescence |
Generally spicate but with the flowers embedded in a thick, fleshy axis, the whole subtended and usually partially or wholly enveloped by a large bract (spathe). |
|
epinastic |
|
development |
laminar structure |
Having the adaxial surface differentiating and growing faster than the abaxial surface, thus, until maturity, development of the former more advanced than that of the latter at any given time and the structure as a whole revolute or recurved. |
|
revolute 1 |
|
margin |
|
Rolled inward abaxially. |
|
syncolporate |
|
architecture |
pollen grain |
Syncolpate, each groove containing a pore. |
|
antrorse |
|
orientation |
|
Directed forward or upward, toward the distal end of the context of reference, parallel or at an acute angle to the bearing structure. |
|
laminar 1 |
|
position |
|
Upon or otherwise directly associated with the lamina (blade) of a foliaceous structure. |
|
excurrent |
|
architecture |
axis, laminar vein |
Branching laterally such that the initial axis retains its prominence over the length of the structure, the succesive orders of branches relatively smaller. See also deliquescent. |
|
areolate |
|
relief |
|
Having numerous, small, irregularly disposed, transversely angular, shallow depressions or low protrusions overall. |
|
haft |
|
STRUCTURE |
|
The narrow portion of a structure that is notably constricted. |
|
obovate |
|
plane shape |
|
Inversely ovate (egg-shaped). |
|
decussate |
|
arrangement |
|
Opposite with successive pairs radially oriented at right angles to one another, thus polystichous with four equidistant ranks. |
|
stephanocolporate |
|
architecture |
pollen grain |
Stephanocolpate, each groove containing a pore. |
|
linear 2 |
|
plane shape |
|
Elongate and narrow with the sides more or less straight and parallel over most of its length. |
|
fissure |
|
FEATURE |
|
A relatively narrow, split or crack in the outer tissue(s) of a structure. |
|
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. |
|
trioecious |
|
reproduction |
taxon |
Having some flowers or spikelets functionally unisexual and some bisexual, some plants having only staminate or only pistillate types, other plants having only bisexual types. |
|
barbellate |
|
architecture |
|
Bearing one or more barbels. |
|
pubescence |
|
CHARACTER |
|
Collective aspect of trichomes borne on the surface. Many of the terms traditionally used for describing pubescence have been defined and used in so many differing and often contradictory ways that they have become hopelessly ambiguous. This is attributable mainly to overdefinition within this portion of the traditional lexicon — that is, to highly arbitrary and widely variant restriction of a term's scope to some one detailed combination of trichome character states (shape, size, orientation, etc.). By derivation these are essentially general terms, really suited only for denoting overall aspect. The diversity actually encountered in nature defies comprehensive and unambiguous resolution into any limited suite of precisely specified, mutually exclusive, complex character states that can be associated with these terms, which are best used only in their general senses. Sometimes, such description will be sufficient in itself; more often, additionally or alternatively, the various attributes of the individual trichomes should be described. This is the only strategy that allows for full description of any possible condition, including the presence of more than one type of trichome. The various terms used for describing pubescence have never been semantically consistent; in some cases they refer to the trichomes themselves, while in others they apply to the bearing surface or structure; e.g., sericeous (the trichomes themselves are collectively silky) versus barbate (the structure is bearded). See also coating, indumentum (vesture). |
|
actinodromous |
|
venation |
|
Having three or more primary veins that diverge radially from a point at or above the base of the blade and run toward the margin, reaching it or not. |
