|
centripetal |
|
development |
|
Proceeding toward the center, thus more advanced peripherally than centrally within a given frame of reference. |
|
oblique 1 |
|
base |
|
Asymmetric about its longitudinal axis. |
|
annual 2 |
|
nominative |
plant |

|
succulent |
|
texture |
|
Herbaceous and juicy, often thickened (incrassate). |
|
clustered 1 |
|
arrangement |
|
Disposed in one or more aggregates, the members of each inserted close together, thence widely divergent from one another. |
|
ovule |
|
STRUCTURE |
|
A complex reproductive structure borne by a seed-plant sporophyte, consisting of outer, sporophytic tissues that enclose a haploid, gametogenic tissue usually regarded as a highly reduced megagametophyte. Following fertilization, the entire structure matures to become a seed that contains an embryo, the first stage of the next sporophytic generation. Ovules (and seeds) are borne naked on megasporophylls (in Pinophyta) or within an ovary (in Magnoliophyta). |
|
circular |
|
arrangement |
bundle scars |
Forming a circle. |
|
branch |
|
STRUCTURE |
|
Any higher-order division of or outgrowth from an axis, vein or veinlet when such division or outgrowth is equivalent in nature to the structure of origin. |
|
trigamous |
|
reproduction |
inflorescence |
Bearing flowers of three differing sexual constitutions; esp. in Asteraceae (Compositae). |
|
adnate |
|
fusion |
dissimilar structure(s) |
Intimately fused with or to one or more other dissimilar structures, the connection(s) with strong histological continuity. See also connate. |
|
pilosulous |
|
pubescence |
|
Finely pilose. |
|
asepalous |
|
architecture |
flower, perianth |
Lacking sepals. |
|
perigynous |
|
insertion |
perianth, calyx, corolla, androecium |
Having its proximal portion adnate to part of the length of the gynoecium, or fused in a separate floral cup that extends part of the length of the gynoecium, the free distal portion thus arising at a level between the base and apex of the gynoecium. See also epigynous, hypogynous. |
|
polygamomonoecious |
|
reproduction |
taxon |
Basically monoecious but with some or all plants bearing some bisexual flowers. |
|
valvate 1 |
|
aestivation |
|
Whorled and with members not overlapping, adjacent members laterally contiguous at their margins. |
|
planoconvex |
|
solid shape |
|
Relatively thin with opposite broad faces, one plane and one convex. |
|
xerocleistogamous |
|
reproduction |
flower |
Normally chasmogamous but facultatively cleistogamous during drier than normal periods. |
|
pterocaulous |
|
architecture |
plant |
Having alate (winged) stems. |
|
weak |
|
texture |
|
Very pliable and unresilient. |
|
prominence |
|
CHARACTER |
|
Elevation or depression of a discrete feature relative to the surrounding surface. |
|
cotyloid |
|
architecture |
flower |
Having general adnation among the different sets of floral structures, thus having the ovary inferior and/or having a floral tube. |
|
cormose |
|
architecture |
plant |
Growing from corms. |
|
rounded |
|
apex |
|
Convex overall and more or less regularly curved. |
|
cyme |
|
nominative |
inflorescence |
Determinate and constituting a compound dichasium or monochasium, the flowers maturing from the center outward (i.e., the distal or inner flowers maturing first); often more or less flat-topped. See also cymule, dichasium, helicoid cyme, monochasium, rhipidium, scorpioid cyme. |
|
scorpioid-cymose |
|
architecture |
inflorescence |
Comprising one or more scorpioid cymes. See also cincinnate, helicoid-cymose. |
