flower |
Having either stamens or pistils absent or non-functional, thus unisexual. |
involucrate 2 |
|
architecture |
capitulum (head) |
Having an involucre. |
branched 2 |
|
architecture |
laminar veinlet |

alternate 2 |
|
arrangement |
structures in multiple whorls |
Having those of each whorl staggered radially in relation to those of the adjacent whorl(s). |
infrapetiolar |
|
position |
bud |

septate 2 |
|
architecture |
trichome |

antisepalous |
|
position |
equivalent floral structures |
Each inserted directly above or below a sepal. In place of this term, the phrase "opposite the sepals" is often used, but that contradicts the sense of opposite as otherwise employed (arrangement of lateral structures along an axis) and should be avoided. |
loose 2 |
|
texture |
|
Soft overall, discontinuously and only weakly cohesive. |
actinodromous |
|
venation |
|
Having three or more primary veins that diverge radially from a point at or above the base of the blade and run toward the margin, reaching it or not. |
lineate 1 |
|
coloration |
|

convolute 2 |
|
arrangement |
cotyledons |
Each rolled or folded inward longitudinally, one enveloping the other. |
microgametophyte |
