bladder |

insertion |
|
Lateral and just below the apex. |

elater 2 |
|
STRUCTURE |
|
An elongate, flattened, hygroscopic enation from a spore, straightening upon desiccation and aiding transport by air; esp. in Equisetaceae. |
colpate |
= fossulate, furrowed, grooved, sulcate, valleculate |
architecture |
|
Having one or more elongate, relatively narrow and shallow depressions (colpi). |
mamma pl. mammae |
|
STRUCTURE |
|
A rounded-conoidal protrusion, resembling the breast of a mammal. |
sickle-shaped 2 |
= falcate |
solid shape |
|
Elongate, strongly compressed, and arcuate in the plane of compression, the two faces more or less plane and parallel, the degree of curvature decreasing distally or not; like a sickle blade. |
capillus pl. capilli |
= hair; > glochid, glochidium; < cilium, trichome |
STRUCTURE |
|
A hair-like trichome. |
ladder-like |
= scalariform |
arrangement |
|
Disposed in vertical sequence with long axes horizontal and parallel. |
tessellate 2 |
= checkered |
relief |
|
Having a pattern of regularly disposed squares marked by raised or depressed vasculature. |
falcate 1 |
= sickle-shaped |
plane shape |
|
Elongate and laterally arcuate with the lateral edges more or less concentric, the degree of curvature decreasing distally or not; like the outline of the face of a sickle blade. |
crassate |
|
architecture |
|
Relatively thick for the type of structure or in the taxonomic context. |
spur 1 |
|
STRUCTURE |
|
A hollow protrusion from a calyx or corolla, often nectariferous. |
dehiscent |
|
dehiscence |
|
Splitting or forming one or more apertures at maturity, the contents thereby released for dispersal. |
porous |
|
porosity |
|
Having vessels present. |
clavate |
= club-shaped |
solid shape |
|
Elongate and basically round in transverse section, the diameter greatest at or near a blunt apex, thence attenuate toward the base, the degree of taper greatest between the middle and the upper quarter. |
…lobed |
? …cleft, …fid, …lobate, …parted, …partite, …segmented |
solid shape |
|
Having the number of lobes indicated by the prefix; as in five-lobed. |
androecial tube |

pubescence |
|
Of or bearing tufts of soft, fine, capillate trichomes that rub off easily. |
tumid |
= swollen, turgid |
solid shape |
|
Engorged in appearance, convex overall with the surface appearing taut , as though from internal pressure. See also inflated, which is not clearly distinct in its application. |
pellucid |
= hyaline; > translucent, transparent |
coloration |
|
Transmitting light uniformly. |
beak 1 |
= rostrum |
STRUCTURE |
|
A relatively long, tapering, more or less rigid and pointed enation or termination. |
