|
sterigma pl. sterigmata |

STRUCTURE |
|
A portion of a lamina that is prolonged and adherent to the supporting axis beneath the point of vascular insertion. |
|
fistulose |
|
solid shape |
|
Basically tubular with closed ends. |
|
calyculate 1 |
|
architecture |
capitulum (head) |

|
carinal |
|
aestivation |
|
Having the petals of the keel (carina) enclosing the others. |
|
appendage |
|
STRUCTURE |
|
Any subordinate structure ontogenetically derived from and associated with a given organ or part. |
|
pubescent 1 (broad sense) |
|
pubescence |
|
Bearing trichomes. This is one of the most ambiguous terms in the botanical lexicon; it should not be used unless its intended meaning is explicit. |
|
strigose |
|
pubescence |
|
Bearing sharp, rigid, appressed, capillate trichomes. See also strigillose (strigulose). |
|
indusium pl. indusia |
|
STRUCTURE |
|
A protective membrane that is an outgrowth from the epidermis and covers a sorus during its maturation; in Polypodiophyta. |
|
parasitic |
|
nutrition |
plant |
Heterotrophic and obtaining essential nourishment directly from other living organisms that derive no reciprocal benefit. |
|
unifacial |
|
architecture |
|
Having two opposite broad surfaces that are essentially similar in appearance. |
|
dull |
|
reflectance |
|
Reflecting only a low proportion of incident light, with no apparent sheen. |
|
rachilla 2 var. rhachilla |
|
STRUCTURE |
|
A second-order axis in an inflorescence, especially the axis bearing the florets in a spikelet; esp. in Cyperaceae, Poaceae (Gramineae). |
|
connate-perfoliate |
|
architecture |
opposite laminar structures |
Having the bases in each pair fused and together encircling the bearing axis. See also amplexicaulous, perfoliate. |

intravaginal |
|
insertion |
|
Within the leaf sheath. |
