|
floricane |
|
STRUCTURE |
|
A biennial or perennial stem after it has begun flowering, when that does not occur until at least its second season of growth; applied especially to the stems of brambles (Rubus spp.). |
|
unequal |
|
size |
equivalent structures |
Distinctly differing in extent. See also equal, subequal. |
|
alete |
|
architecture |
spore |
Lacking a tetrad scar (surficial ridge or angle resulting from coherence with others produced from the same spore mother cell). |
|
silicle |
|
nominative |
fruit |
Like a silique, but only slightly longer than broad to broader than long; esp. in Brassicaceae (Cruciferae), Capparaceae. |
|
vascular |
|
position |
|
Upon or otherwise directly associated with the vasculature. |
|
elongate |
|
plane shape |
|
Longer in one dimension than in any other. |
|
superposed 2 |
|
insertion |
buds |
Axillary in pairs, one member of each pair directly above the other. |
|
andropetalous 1 |
|
architecture |
flower, androecium |
Having petaloid, sterile stamens. |
|
corolla pl. corollae, corollas |
|
STRUCTURE |
|
Collectively, the petals of a flower, whether distinct or connate; the inner or distal envelope of a differentiated perianth, whether the other envelope (calyx) is actually present or is deemed to be absent due to evolutionary reduction. |
|
solitary 1 |
|
arrangement |
|
Disposed singly, each remote from any others. |
|
villosulous |
|
pubescence |
|
Finely villose (shaggy, villous). |
|
canalicular |
|
insertion |
|
Upon or otherwise directly associated with the channel of a petiole or petiolule. |
|
muricate |
|
relief |
|
Having short, hard, more or less acute, transversely round protrusions overall. See also muriculate. |
|
retrorse |
|
orientation |
|
Directed generally backward, toward the proximal end of the context of reference, parallel or at an acute angle to the bearing structure. |
|
syncarpous |
|
architecture |
flower, gynoecium |
Having one or more compound pistils. |
|
antisepalous |
|
insertion |
equivalent floral structures |
Each inserted directly above or below a sepal. In place of this term, the phrase "opposite the sepals" is often used, but that contradicts the sense of opposite as otherwise employed (arrangement of lateral structures along an axis) and should be avoided. |
|
spinulose |
|
architecture |
|
Finely spinose. |
|
node |
|
STRUCTURE |
|
One of the evident sectors of a stem that occur sequentially along its length and from which leaves (megaphylls) and lateral branches arise exogenously. The anatomy of nodes differs from, but is not abruptly distinct longitudinally from, that of the intervening sectors (internodes), with which it is smoothly confluent and from which is distinguished by the lateral transit and egress of vascular traces interconnecting the stem and the leaves and branches that it bears. |
|
tertiary vein |
|
STRUCTURE |
|
A strand belonging to the third order of vasculature in a leaf or other basically laminar structure, except when that is the ultimate order (consisting of veinlets); branching from a primary or secondary vein. See also costa, lateral vein, primary vein, rib, secondary vein, veinlet. |
|
habit |
|
CHARACTER |
|
General appearance and/or function, usually including explicit or implicit reference to one or more aspects of habitat or other features of the external environment; a logically imprecise traditional category of terms that overlaps conceptually with architecture, arrangement, duration, insertion, location, orientation, position, shape, and texture. |
|
cuniculate |
|
solid shape |
elongate structure |
Hollow over a significant part of its length, the interior open at the end of the hollow portion. |
|
pollen |
|
STRUCTURE |
|
Collectively, the spores or grains produced within the thecae of anthers, each containing a very small microgametophyte (or its evolutionary homologue); serving as disseminules from which microgametes are released after transport to a receptive micropylar pollen droplet (in Pinophyta) or stigma (in Magnoliophyta) by a variety of vectors, notably wind, water, insects, bats, and birds. |
|
chaff 2 |
|
STRUCTURE |
|
Collectively, the glumes, lemmata, and paleae of mature spikelets; in Poaceae (Gramineae). |
|
oblong 2 |
|
solid shape |
|
Compressed-ellipsoid, the sides approximately parallel from near one end to near the other. See also ellipsoid(al). |
|
decurved |
|
orientation |
|
Curving abaxially. See also incurved. |
