corolla pl. corollae, corollas |
|
STRUCTURE |
|
Collectively, the petals of a flower, whether distinct or connate; the inner or distal envelope of a differentiated perianth, whether the other envelope (calyx) is actually present or is deemed to be absent due to evolutionary reduction. |

pubescence |
|
Of or bearing tufts of soft, fine, capillate trichomes that rub off easily. |
seriate |
= cyclic, verticillate, whorled |
arrangement |
|
Disposed along the axis in groups of three or more, the members of each group (cycle, series, verticil, whorl) inserted around the axis at the same level. |
capillus pl. capilli |

STRUCTURE |
|
A hair-like trichome. |
hypocotyl |
