|
CHARACTER |
|
Degree or nature of evidence when present within the context in point. |
apetalous |
|
architecture |
flower, perianth |
Lacking petals. |
naked 2 |
|
architecture |
bud |
Lacking enclosing protective scales, the outermost embryonic components exposed and not differing significantly from those within. See also perulate. |
dichasiate |
|
architecture |
inflorescence |
Comprising one or more simple or compound dichasia. See also cincinnate, cymose, cymulose, helicoid-cymose, monochasiate, scorpioid-cymose. |
surface |
|
FEATURE |
|
The exterior or bounding area or layer of any structure, regarded as being infinitely thin; usually described as to relief, reflectance, and/or vesture. |
asymmetric(al) 1 |
|
plane shape |
|
Not divisible into essentially equal halves along any line or plane. |
decurved |
|
orientation |
|
Curving abaxially. See also incurved. |
obovate |
|
plane shape |
|
Inversely ovate (egg-shaped). |
non-septate |
|
architecture |
trichome |
Lacking transverse inter- or intracellular septa or partitions. |
tetrad |
|
STRUCTURE |
|
A group of four pollen grains originating from a single pollen mother cell. |
beard |
|
STRUCTURE |
|
A growth of relatively long, erect, flexible, capillary trichomes from one or more limited sectors of a structure's surface. |
entire |
|
margin |
|
Uninterrupted; not deviating significantly from its general line, thus lacking any localized convexities or concavities. |
trioecious |
|
reproduction |
taxon |
Having some flowers or spikelets functionally unisexual and some bisexual, some plants having only staminate or only pistillate types, other plants having only bisexual types. |
brochidodromous |
|
venation |
|
Having a single median primary vein that branches to either side along its length, the secondary veins incurving strongly near but short of the margin, interconnecting serially, and forming a succession of marginal loops. |
elaminate |
|
architecture |
foliaceous structure |
Lacking an expanded, more or less planate, distal portion (lamina or blade). |
extrafloral |
|
position |
|
Outside and proximal to the flower; esp. nectaries. |
pappose |
|
architecture |
flower, fruit |
Bearing a pappus; esp. in Asteraceae (Compositae). |
equitant |
|
arrangement |
|
Alternate, distichous, basal, and congested, each conduplicate with its lateral edges overlapping and/or overlapped by those of the immediately adjacent one(s). |
perisperm |
|
STRUCTURE / SUBSTANCE |
|
A genetically diploid (2n chromosomes) nutritive tissue in a seed; containing stored carbohydrate and/or oil utilized by the embryo prior to and especially upon germination; derived from the nucellus. See also endosperm (albumen). |
chasmogamous |
|
reproduction |
flower |
Having the perianth open at anthesis, allowing deposit of pollen from other flowers (physiological receptivity aside). |
valve |
|
STRUCTURE |
|
Any longitudinal segment of a fruit wall delimited by lines of dehiscence. |
zoned |
|
coloration |
|
Having two or more fairly distinctly delineated areas of contrasting hues and/or intensities. |
gummy |
|
texture |
|
Highly viscous and sticky, liquid or more or less deformably solid, sometimes more or less elastic. |
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. |
glochidiate |
|
pubescence |
|
Bearing glochids (glochidia). |
