STRUCTURE |
|

|
perisperm |
|
STRUCTURE / SUBSTANCE |
|
A genetically diploid (2n chromosomes) nutritive tissue in a seed; containing stored carbohydrate and/or oil utilized by the embryo prior to and especially upon germination; derived from the nucellus. See also endosperm (albumen). |
|
foveolate |
= fine-pitted, scrobiculate |
relief |
|
Finely foveate (pitted). |
|
proximal |
> basal |
position |
|
Upon or associated with the portion of a structure closest to its developmental origin. |
|
headed 2 |
= capitate |
solid shape |
|
Abruptly enlarged distally to a relatively short, terminal portion that is basically round in transverse section. |
|
ribbed 2 |
|
solid shape |
|
Having two or more prominent, elongate, relatively narrow, essentially parallel protrusions that extend over all or most of its length or circumference. |
|
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). |
|
sporophyte |
|
PLANT |
|
The main, ultimate, spore-bearing stage in the diploid (2n chromosomes) phase of a taxon's life cycle. Two morphologically and genetically distinct and alternate phases together constitute the complete life cycle in sexually reproducing taxa, the other phase (gametophytic) being haploid (n chromosomes). Any taxon whose life cycle is confined to one or the other phase is limited to asexual means of reproduction, since sexual reproduction with consequent genetic recombination is impossible without alternation between haploid and diploid states via meiosis and fertilization. The term sporophytic applies to any part of the diploid phase, including all unicellular to multicellular entities belonging to it, whereas sporophyte is reserved for the principal and directly spore-producing stage of that phase. |
|
succulent |
|
texture |
|
Herbaceous and juicy, often thickened (incrassate). |
|
trabecula pl. trabeculae |
< septum |
STRUCTURE |
|
A transverse wall or partition that fully or partially separates two chambers within a sporangium. |
|
ventricose |
= bellied |
solid shape |
|
Bulging unilaterally near the middle, as though with a belly. |
|
bracteole 2 |
= bractlet, prophyll(um); < bract |
STRUCTURE |
|
A second- or higher-order bract within, and subtending some portion of, an aggregate branching structure, especially when subtending a flower. |
|
chalaza pl. chalazae, chalazas |
|
STRUCTURE |
|
The basal (proximal) portion of an ovule, adjacent to its junction with the funiculus. |
|
corniform |
= horn-shaped |
solid shape |
|

|
masculine |
= male |
reproduction |
|
