solid shape |
|
Convex or compressed-convex overall with a distal peak or ridge, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a hood or cowl. See also helmet-shaped (galeate, galeiform), which overlaps conceptually. |

< labium, lip |
STRUCTURE |
|
The third petal of a tripetalous flower when distinctively different from the other two, usually enlarged relative to them and/or differently shaped or colored, usually apparently the abaxial (lower) petal of the three due to resupination during ontogenesis; esp. in Orchidaceae. |
|
trumpet-shaped |
= tubiform |
solid shape |
|
Obteretely tubular with a relatively short distal flare (the limb if a perianth, calyx, or corolla). |
|
balding |
= glabrescent |
pubescence |
|
Becoming bald (glabrous, psilate) with age. |
|
micropyle |
|
FEATURE |
|
The small pore in the integuments of an ovule at its apex, through which the pollen tube grows; or the corresponding aperture or scar in the coat of the seed that develops subsequently. |
|
calyptrate |
|
architecture |
|
Having or constituting a calyptra. |
|
odorless |
|
odor |
|
Lacking a distinct odor. |
|
cochlear |
|
aestivation |
|
Imbricate with one member larger than and exterior to the others, parallel to one that is internal to all the others, strongly incurved, and enclosing the others. |
|
peripterous |
|
solid shape |
|
Alate with a single transversely encircling wing. |
|
crumpled |
= corrugate |
aestivation |
|
Having members tightly and irregularly folded, the whole appearing as though wadded upon emergence. |
|
proximal |
> basal |
insertion |
|
Upon or associated with the portion of a structure closest to its developmental origin. |
|
dorsal (not recommended) |
= abaxial |
position |
|
On or pertaining to the side or portion of a lateral structure that faces (or would face) away from the bearing axis when (or if) the axis of the lateral structure is (or were) oriented in the same general direction as the bearing axis. |
|
ribbed 1 |
= costate |
architecture |
|
Having one or more ribs (costae). |
|
…faced |
|
solid shape |
|
Having relatively large, flat or shallowly curved portions of the external surface that are bounded by more or less distinct angular discontinuities in that surface, of the number indicated by the prefix; as in three-faced. |
|
sporophyll |
= spore leaf; > fertile frond |
STRUCTURE |
|
A leaf or homologous structure that bears sporangia. See also megasporophyll (macrosporophyll, not recommended), microsporophyll. |
|
hermaphroditic |
= bisexual |
reproduction |
|
Having functional reproductive structures of both sexes. See also perfect. |
|
subvalvate |
|
dehiscence |
|
Incompletely or partly valvate. |
|
involucre 2 |
|
STRUCTURE |
|
One or more closely proximate whorls, or a compact spiral, of bracts (phyllaries) surrounding (proximal to) the compound receptacle (torus) and florets of a capitulum (head); in Asteraceae (Compositae). |
|
torus 2 pl. tori |
= receptacle |
STRUCTURE |
|
The short, expanded, compound axial structure surmounting a peduncle and basal to two or more flowers, or to the florets of a capitulum (head) in Asteraceae (Compositae), where it may bear paleae (receptacular bracts), scales, bristles, trichomes, or subulate enations, and may be smooth or variously pitted (alveolate, foveolate). |
|
ventral (not recommended) |
= adaxial |
position |
|
On or pertaining to the side or portion of a lateral structure that faces (or would face) toward the bearing axis when (or if) the axis of the lateral structure is (or were) oriented in the same general direction as the bearing axis. |
|
aseptate |
|
architecture |
|
Lacking internal walls or partitions (septae). |
|
marginal |
|
position |
|
Upon or otherwise directly associated with the margins. |
|
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. |
|
circumcaulous |
|
insertion |
|
Upon and surrounding the stem. |
