|
…-scalloped |
= …crenate |
margin |
|
Having the number of orders of scallops (crenae) indicated by the prefix, one upon another; as in twice-scalloped. See also …-sawtoothed (…serrate), …-toothed (…dentate). |
|
floral |
|
position |
|
Upon, within, or associated with the flowers. |
|
gynoecium pl. gynoecia var. gynaecium |
|
STRUCTURE |
|
The pistil(s) of a single flower together with any ontogenetically equivalent or subordinate structures present, taken collectively; the total female (ovule-producing) structural complement of a single flower. It may include one to many pistils, each simple or compound. |
|
stomium pl. stomia |
= stomatal pore |
FEATURE |
|
The opening in the wall of a sporangium, between the lip cells, through which the spores exit; in Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta. |
|
leaf-opposed |
|
insertion |
|
Nodal and directly opposite the leaf. |
|
muscariform |
= broom-shaped, penicillate |
solid shape |
|
Having a proximal axis that bears a distal cluster of elongate slender branches or appendages, these variously ascending to erect; like a broom. |
|
casing |
|
STRUCTURE |
|
The portion (if any) of a floral tube that is adnate to the gynoecium. See also collar, neck. |
|
palea 2 pl. paleae, paleas |
= pale, palet |
STRUCTURE |
|
The distal bract of the (usually) two that immediately subtend the flower in a grass (Poaceae) spikelet; the other is the lemma. |
|
conic(al) |
= cone-shaped |
apex |
|
Transversely round, essentially triangular in median longitudinal section, and broadest proximally. See also obconic(al). |
|
