rhizophore |
|
STRUCTURE |
|
A stem branch that bears no leaves and from which roots eventually arise; esp. in Selaginellaceae. |
|
extrafloral |
|
position |
|
Outside and proximal to the flower; esp. nectaries. |
|
semicraspedodromous |
|
venation |
|
Having a single median primary vein that branches to either side along the length of the lamina, each secondary vein running thence toward and bifurcate near the margin, one branch terminating at the margin, the other upwardly arcuate and merging with the superadjacent secondary vein, thus forming one of a series of marginal loops. |
|
full |
|
extent |
|
Reaching from the ovary wall or pericarp to the center of the ovary or fruit and from the apex to the base of its interior, thus separating adjacent locules completely. |
|
sporangiophore |
< stalk |
STRUCTURE |
|
A stalk that bears one or more sporangia. |
|
subtending |
|
insertion |
|
Arising from the axis just below and very near to the base of some other specified lateral structure. This term is meaningless if the structure that is subtended is not indicated. |
|
intruded |
|
placentation |
|
Upon partial septa excrescent from the wall of a compound, unilocular ovary. |
|
toothlet |
|
STRUCTURE |
|
A diminutive tooth (dens). See also sawtooth, sawtoothlet, scallop (crena), scalloplet (crenule). |
|
lip |
= labium; > labellum |
STRUCTURE |
|
Any substructure that resembles a lip, especially a portion of a perianth, calyx or corolla. |
|
veinlet |
|
STRUCTURE |
|
A strand belonging to the ultimate (least in diameter) order of vasculature in a leaf or other basically laminar structure when that order consists of strands ending freely within areoles and/or connecting distally by pairs across areoles; absent in some taxa. See also costa (rib), lateral vein, midvein (midnerve, midrib), primary vein, secondary vein, tertiary vein, vein (nerve). |
|
adventitious root |
|
STRUCTURE |
|
A root that arises laterally from some part of a shoot, often from the lower portion of a main stem. |
|
articulation |
= joint |
STRUCTURE |
|
A distinct, relatively narrow zone of demarcation between adjacent main portions of an elongate structure, often thicker than the rest of the structure and sometimes a site of eventual abscission. |
|
mammose |
|
solid shape |
|
Having mammae. |
|
bristly |
> hispid, setose |
pubescence |
|
Of or bearing relatively long and slender, more or less straight, terete, fine-pointed, stiff trichomes. |
|
nutrition |
|
CHARACTER |
|
Mode of acquiring nutrients. |
|
cilium 1 pl. cilia |
> capillus, hair; >< trichome |
STRUCTURE |
|
A hair-like trichome or other surficial process. |
|
…partite |
? …cleft, …fid, …lobate, …lobed, …parted, …segmented |
solid shape |
|
Having the number of lobes, divisions or segments indicated by the prefix; as in tripartite. |
|
reduced |
|
size |
|
Unusually or unexpectedly small. |
|
foliar |
|
insertion |
|
Upon or otherwise directly associated with the leaves. |
|
sperm |
> antherozoid, spermatozoid |
STRUCTURE |
|
A male gamete. |
|
half-obterete |
= semiobterete |
solid shape |
|
Inversely half-terete; obterete but flattened on one side. |
|
striped |
|
coloration |
|
Having one or more elongate, relatively narrow and, when multiple, more or less parallel, areas of contrasting hue and/or intensity. |
|
inflexed |
|
orientation |
|
Bent adaxially at some point along its length. |
|
testicular |
= testes-shaped |
solid shape |
|
Bilaterally symmetrical, each side essentially oblate and constrictedly confluent with the other; like the overall shape of a pair of mammalian testes. |
|
lenticular 1 |
= biconvex, lens-shaped |
plane shape |
|
Elongate, narrow, broadest at the middle, attenuate to acute ends, the sides convex; like the outline of a double-convex lens viewed from its edge. |
