percurrent 1 |
|
architecture |
primary or secondary laminar veins |
Running through the entire length of the lamina (blade), or all the way to its margin. |
|
complete |
|
architecture |
flower |
Having all sets of basic floral structures (calyx and corolla, or else undifferentiated perianth; androecium; and gynoecium) present and functionally normal. |
|
oblong 2 |
|
solid shape |
|
Compressed-ellipsoid, the sides approximately parallel from near one end to near the other. See also ellipsoid(al). |
|
secund 2 |
|
architecture |
stem |
Having the petioles oriented such that the main bodies of all the leaves lie to one side of the bearing stem. |
|
pseudobulb |
|
STRUCTURE |
|
An enlarged internode of an aboveground stem, storing water and photosynthate, resembling a bulb; esp. in Orchidaceae. |
|
bud-scale scar |
|
FEATURE |
|
A scar on a stem due to abscission of a bud scale. The scar(s) encircle(s) the axis to which the bud was terminal, each single scar having an outline like that of a transverse section through the base of the bud scale that was inserted there. Sets of bud scale scars (one set per bud) usually delimit seasonal stem growth increments in temperate zone taxa. |
|
woody-clumping |
|
habit |
plant |
Having or developing the character of a woody clump. See also arboreous, arborescent, bushy, frutescent, fruticose, shrubby, subshrubby, suffrutescent, suffruticose, tree-like. |
|
sorus pl. sori |
|
STRUCTURE |
|
A cluster of sporangia borne upon a fertile frond, usually on its abaxial surface; often covered during maturation by a protective membrane, the indusium, that is an outgrowth from the epidermis; in Polypodiophyta. |
|
extrorse |
|
dehiscence |
anther |
Opening outwardly, on the abaxial side. See also introrse, latrorse. |
|
calyculate 2 |
|
architecture |
flower |
Subtended by a calyculus (epicalyx). |
|
alternate 2 |
|
arrangement |
structures in multiple whorls |
Having those of each whorl staggered radially in relation to those of the adjacent whorl(s). |
|
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. |
|
spur 1 |
|
STRUCTURE |
|
A hollow protrusion from a calyx or corolla, often nectariferous. |
|
dichotomous |
|
architecture |
axis |
Branching by division of the apical meristem producing two coordinate but not necessarily equal derivatives from each division. |
|
internode |
|
STRUCTURE |
|
Any portion of a stem between two successive nodes. |
|
cuspidate |
|
apex |
|
Tapering gradually to a rigid tip composed of both vascular and laminar tissues. |
|
conoidal |
|
solid shape |
|
Generally but not strictly conic. |
|
symmetric(al) 2 |
|
architecture |
flower |
Having the perianth members in whorls that are actinomorphic and equal in number of members. |
|
deliquescent 2 |
|
texture |
|
Delicately fleshy and liquifying at maturity or with pressure; e.g., petals of Tradescantia (Commelinaceae). |
|
naked 2 |
|
architecture |
bud |
Lacking enclosing protective scales, the outermost embryonic components exposed and not differing significantly from those within. See also perulate. |
|
pallid |
|
coloration |
|
Relatively pale; not strongly colored. |
|
laminar 1 |
|
position |
|
Upon or otherwise directly associated with the lamina (blade) of a foliaceous structure. |
|
filament |
|
STRUCTURE |
|
The stalk, when present, of a stamen, clearly differentiated from and bearing at its summit an anther. |
|
acropetal |
|
development |
|
Proceeding toward the apex, thus more advanced basally or proximally than apically or distally within a given frame of reference. |
|
non-septate |
|
architecture |
trichome |
Lacking transverse inter- or intracellular septa or partitions. |
