calyptrate |
|
architecture |
|
Having or constituting a calyptra. |
|
receptacle 2 |
= torus |
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). |
|
extravaginal |
|
insertion |
|
Distal to or outside the leaf sheath. |
|
muriculate |
|
relief |
|
Finely muricate. |
|
conduplicate 2 |
= duplicate |
vernation |
|
Each leaf folded sharply inward along its longitudinal axis, the adaxial surfaces of each side facing one another. |
|
waxen 1 |
= ceraceous, cereous, waxen; > caesious, glaucescent, glaucous, pruinose |
coating |
|
Covered with wax or a wax-like substance. |
|
gynostemium pl. gynostemia |
= column, gynandrium |
STRUCTURE |
|
A central floral structure consisting of the partly to wholly fused (connate and adnate) androecium and gynoecium; esp. in Orchidaceae. |
|
spore case |
= sporangium |
STRUCTURE |
|
A spore-producing organ; basically capsular, often supported by a slender stalk (sporangiophore), often lidded (operculate). In Bryophyta and Polypodiophyta, a distinct portion of the sporangial wall effects regular dehiscence at maturity. Spore cases or their equivalents are also present, but of little or no descriptive significance, in seed plants. |
|
lobate |
? cleft, dissected, divided, lobed, parted, partite, segmented |
plane shape |
|
Having one or more component sectors or peripheral protrusions that is/are delimited by concavities in the surface or margin and that is/are not proximally distinct from the remainder of the whole. The meanings of this term and its approximate synonyms sometimes have been supposed to differ according to the depth of the delimiting concavities relative to the midline or midpoint of the overall structure, and/or to the shape or proportions of the protusions or sectors; however, there has been little consistency in the applications of the various terms according to such distinctions, which are ones only of degree and are necessarily arbitrary in any case. In general usage, these terms differ only indistinctly and connotatively: cleft, lobed (or lobate), parted (or partite) and segmented tend to connote fewer protrusions or sectors; lobate usually connotes as well a generally rounded shape; dissected tends to connote more numerous sectors that are elongate and angular. See also cut (incised, lacerate, torn), laciniate (slashed). |
|
tuberculose 2 |
= tubercular |
solid shape |
|
Comprising small knot-like segments. |
|
oleaginous 2 |
= greasy, oily, unctuous |
texture |
|
Liquid or deformably solid, cohesive, and slippery to the touch. |
|
crustaceous |
= crusty |
texture |
|
Thin, dry, hard, and brittle. |
|

|
architecture |
|
Bearing one or more barbels. |
|

|
Finely strigose. |
|
dot-like |
= punctiform |
plane shape |
|
Very small and generally circular in outline. |
|
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. |
|
mitriform |
= mitre-shaped |
solid shape |
|
Broadest and transversely round to oval proximally, tapering bilaterally above the middle to a central peak; like a peaked hat or cap. |
|
vernation |
|
CHARACTER |
|
Disposition of leaves in the bud. |
|
mixed-craspedodromous |

Covered with small, relatively broad, irregularly shaped, obtuse protrusions. |
|

|
Bearing lepides (squamae). See also squamellose. |
