integument |
|
STRUCTURE |
|
A distinct layer of tissue that encloses and serves to protect the other tissues of an organ, especially a seed. |
cylindric(al) |
|
solid shape |
|
Solid and transversely round with a more or less uniform diameter, the ends blunt. |
thermocleistogamous |
|
reproduction |
flower |
Normally chasmogamous but facultatively cleistogamous during periods of lower-than-normal temperature. |
inflexed |
|
orientation |
|
Bent adaxially at some point along its length. |
epidermis pl. epidermides, epidermises |
|
STRUCTURE |
|
The anatomically distinct, outermost, living tissue that encloses and protects the other tissues of a plant organ or part, usually overlaid by an exuded waxy cuticle; resulting from primary growth, disrupted and shed as a consequence of secondary growth if that occurs; consisting mainly of cells not further specialized, otherwise including various types of more specialized cells associated with trichomes and stomates. |
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). |
isostemonous |
|
architecture |
flower, androecium |
Having the stamens essentially alike in size and shape. |
scar |
|
FEATURE |
|
A discontinuity in surface color and/or relief due to abscission of a structure formerly borne there. |
calyculate 2 |
|
architecture |
flower |
Subtended by a calyculus (epicalyx). |
acroscopic |
|
orientation |
subordinate structure |
Directed, facing, or pointing ("looking") toward the apex of the bearing structure. |
manifestation |
|
CHARACTER |
|
Degree or nature of evidence when present within the context in point. |
pubescent 1 (broad sense) |
|
pubescence |
|
Bearing trichomes. This is one of the most ambiguous terms in the botanical lexicon; it should not be used unless its intended meaning is explicit. |
diffuse |
|
architecture |
plant, stem |
Having branches remote and divergent to divaricate. |
cell 1 |
|
STRUCTURE |
|
Any of the basic structural/functional units that collectively or individually make up the various tissues of a plant; comprising, at least while physiologically active, a nucleus with included genetic material (chromosomes), a surrounding cytoplasm with included organelles (e.g., ribosomes, mitochondria, plastids), an enclosing membrane, and an exterior cellulosic wall. |
rachilla 1 var. rhachilla |
|
STRUCTURE |
|
A second- or higher-order axis of a compound leaf blade, bearing higher-order rachillae, leaflets, pinnules and/or tendrils. |
flesh |
|
STRUCTURE |
|
Tissue that is fairly firm and dense, juicy or at least moist, and easily cut. |
soboliferous |
|
architecture |
plant |
Having several, loosely clumped, principal stems that arise from a common underground stem system, each distinct above ground level. |
silique |
|
nominative |
fruit |
Dry, septifragal, two-loculed and derived from a single, superior, compound ovary; much longer than broad; dehiscing along two sutures, one adaxial, one abaxial, leaving a single persistent septum (replum) after the two valves of the pericarp have fallen away; esp. in Brassicaceae (Cruciferae), Capparaceae. See also silicle. |
drupaceous |
|
architecture |
fruit |
Having the structure and texture of a drupe. |
utricle |
|
nominative |
fruit |
Dry, indehiscent, one-seeded and with the pericarp thin and free from the seed; derived from a single, superior, simple ovary. |
…ciliate |
|
architecture |
|
Bearing the number of cilia indicated by the prefix. |
ochrea |
|
STRUCTURE |
|
See ocrea. |
spinose 1 |
|
apex |
|
Terminating in a rigid, tapering, sharp continuation of the central primary vein. See also spinulose. |
elongate |
|
solid shape |
|
Longer in one dimension than in any other. |
palmatifid |
|
solid shape |
|
Palmately lobate; having three or more lobes whose longitudinal axes radiate from a common point. |
