|
anisostemonous |
|
architecture |
flower, androecium |
Having stamens unequal in size and/or shape. |
|
capitulescence |
|
architecture |
|
Mode or progressive pattern of bearing capitula (heads); most appropriately described using adjectival terms; esp. in Asteraceae (Compositae). |

|
geminicolpate |

pollen grain |
Having four or more surficial grooves (colpi) disposed in pairs. |
|
trilete |
|
architecture |
spore |
Having a triradiate tetrad scar. |
|
hollow |
= excavate(d) |
architecture |
axis |
Having pith tissue absent or disintegrating prior to axial maturity, resulting in an uninterrupted cavity running the length of the axis. Semantically, this term and its synonym refer to the axis, not to the pith itself, although the latter application has been traditional. |
|
amphistomatous |
= amphistom(at)ic |
architecture |
foliaceous structure |
Having stomata on both the adaxial and abaxial surfaces. |
|
cross-shaped 1 |
= cruciate |
architecture |
corolla, perianth |
Having four petals or tepals disposed in pairs of opposite members, the whole resembling a cross when viewed from above. |
|
exstipulate |
= estipulate |
architecture |
leaf |
Lacking stipules. |
|
helicoid-cymose |
> cincinnate |
architecture |
inflorescence |
Comprising one or more helicoid cymes. See also scorpioid-cymose. |
|
chorisepalous |
= aposepalous, dialysepalous, polysepalous |
architecture |
flower, perianth, calyx |
Having two or more distinct sepals; having the sepals unfused. |
|
polyplicate |
|
architecture |
pollen grain |
Inaperturate with meridional folds, thus appearing longitudinally wrinkled. |
|
acephalous 1 |
= headless |
architecture |
|
Not terminated or surmounted by a head-like structure, esp. when one might be expected. |
|
apopetalous |
= choripetalous, dialypetalous, polypetalous |
architecture |
flower, perianth, corolla |
Having two or more distinct petals; having the petals unfused. |
|
continuous 1 |
|
architecture |
inflorescence |
Having the flowers or branch units distributed evenly along the axis, with no significant interruption. |
|
dendritic |
= tree-like |
architecture |
|
Like the branched axial structure of a tree. |
|
radiant 1 |
|
architecture |
capitulum (head) |
Bearing one or more peripheral series of florets that are bisexual, pistillate, or neuter and that have relatively large actinomorphic corollas, and one or more central series of usually bisexual florets that have relatively small actinomorphic corollas; in Asteraceae (Compositae). |
|
flabelliramous |
= polytomous |
architecture |
axis |
Branching by division of the apical meristem to produce more than three equal derivatives. |
|
single-leafleted |
= one-leafleted, unifoliolate |
architecture |
foliaceous structure |
Structurally compound but with only one leaflet, whose nature (as a leaflet, not a leaf) is revealed by an evident articulation with the petiole, this condition presumably derived by evolutionary reduction from a multifoliolate precursor. |
|
syndetocheilic |
= compound-lipped |
architecture |
stomate |
Having subsidiary cells derived from the primary stoma mother cell and thus immediately related ontogenetically to the guard cells. |
|
winged 2 |
= alate, saccate, vesiculate |
architecture |
pollen grain |
Having lateral lobes or enations that resemble sacs or somewhat inflated wings. |
|
stalked 1 |
= pedicellate |
architecture |
flower |
Having a pedicel. |
