|
habit |
plant |
Growing upon the ground, usually rooted in it. |
|
elaiosome |
|
STRUCTURE |
|
A fleshy outgrowth from the seed coat (testa) that contains a high proportion of oil, usually attracting ants for dispersal. |
|
subequal |
|
size |
equivalent structures |
Nearly uniform in extent. See also equal, unequal. |
|
flanged |
|
plane shape |
|
Having a relatively broad circumferential rim or ridge that protrudes laterally. |
|
suffused |
|
coloration |
|
Having two or more hues, shades, and/or intensities intermingled, the contrasting components distinguishable only submacroscopically. |
|
herb |
|
nominative |
plant |
Annual, biennial, or perennial with no woody (lignified) tissue in any part of the shoot; when persisting over more than one growing season, the parts of the shoot dying back seasonally. |
|
sorus pl. sori |
|
STRUCTURE |
|
A cluster of sporangia borne upon a fertile frond, usually on its abaxial surface; often covered during maturation by a protective membrane, the indusium, that is an outgrowth from the epidermis; in Polypodiophyta. |
|
anadromous |
|
venation |
|
Having the first lateral vein in each pinna or primary segment of the frond arise from its midvein on the side toward the apex of the frond, the pinnule or secondary segment that it leads to often disproportionately larger than the next distal ones. |
|
homosporous |
|
reproduction |
taxon |
Producing only one type of spore, each spore giving rise to a gametophyte that bears gametangia of both sexual types. |
|
secund 2 |
|
architecture |
stem |
Having the petioles oriented such that the main bodies of all the leaves lie to one side of the bearing stem. |
|
spinulose |
|
margin |
|
Finely spinose. |
|
bract 2 (strict sense) |
|
STRUCTURE |
|
Any primary or first-order lateral structure ontogenetically and anatomically analogous with, and therefore presumably homologous with, but relatively smaller than, a leaf, especially when subtending an inflorescence, other reproductive structure, or portion thereof; putatively, an evolutionarily reduced leaf. |
|
pollinium pl. pollinia |
|
STRUCTURE |
|
A mass of coherent pollen grains disseminated as a unit by adhering to a pollinating insect, representing the entire content of a single theca or of fused thecae; often distally attenuate to a sterile caudicle (translator arm), which may attach to a viscidium, either directly or through an intervening stipe; esp. in Asclepiadaceae, Orchidaceae. |
|
column 2 |

|
adherent |
|
fusion |
dissimilar structure(s) |
Superficially joined with or to one or more other dissimilar structures, the connection(s) with no significant histological continuity. See also coherent. |
