hilum 1 pl. hila |
|
FEATURE |
|
The scar left on a seed at the point of its abscission from the funiculus. |
|
dichasiate |
|
architecture |
inflorescence |
Comprising one or more simple or compound dichasia. See also cincinnate, cymose, cymulose, helicoid-cymose, monochasiate, scorpioid-cymose. |
|
pachycaulous |
|
architecture |
plant |
Having thick, more or less succulent stems. |
|
seed |
|
STRUCTURE |
|
A mature or ripened ovule containing an embryonic sporophyte and a nutritive tissue (endosperm or perisperm) with stored food that sustains the initial growth of the embryo upon germination, except when such food reserve is stored instead in the cotyledon(s) of the embryo itself, these enclosed by one or two integuments (the testa), the whole serving as a propagule. A fertile seed (one containing a viable embryo) normally results from sexual fertilization of an egg by a sperm; however, fertile seeds are sometimes produced asexually by apomictic processes (e.g., parthenogenesis). |
|
acrocaulous |
|
insertion |
|
At or very near the stem tip. |
|
pseudostem |
|
STRUCTURE |
|
A structure that resembles a stem but is not part of the axial system of a shoot, lacking anatomical differentiation into nodes and internodes. |
|
straight |
|
course |
|
Lacking significant curves or bends. |
|
collateral |
|
insertion |
buds |
In pairs within or immediately straddling the leaf axils, the members of a pair lateral to one another. |
|
incurved |
|
orientation |
|
Curving adaxially. See also decurved. |
|
dovetailing |
|
habit |
trichome |
Papillate and serving to hold a surface to the opposing one of an appressed structure by interlocking with others on the opposing surface; sometimes furcate. |
|
free |
|
fusion |
dissimilar structure(s) |
Not fused with or joined to any other dissimilar structure(s). |
|
pyxis pl. pyxides |
|
nominative |
fruit |
Like a capsule but circumscissile, the one or more seeds being released from the locule(s) upon separation of the distal, cap-like portion of the pericarp. See also diplotegium. |
|
subpetiolar |
|
insertion |
|
Just below the point of petiole insertion. |
|
intercostal |
|
position |
|
Between the costae. |
|
peloric |
|
architecture |
corolla |
Regular when the usual condition in the taxon is irregular. |
|
valvate 3 |
|
dehiscence |
anther |
Poricidal with the pores formed by the raising of small flaps (valves) in the exterior wall. |
|
androgynecandrous |
|
reproduction |
taxon |
Monoecious, each inflorescence having distal and proximal sectors with only staminate flowers and between them a central sector with only pistillate ones. |
|
raphal |
|
derivation |
aril |
Produced or resulting from a modification of the raphe. |
|
calyx tube |
|
STRUCTURE |
|
A relatively narrow, fully connate portion of a synsepalous (gamosepalous) calyx proximal to a broader portion (limb) that comprises the distinct or connate distal portions of the sepals. |
|
petal |
|
STRUCTURE |
|
One of the one or more constituent members of a corolla; colored and showy in many taxa, inconspicuous in size and/or color in others; may be distinct or else connate with one or more others, and/or may be free or else adnate to one or more other floral structures. |
|
soboliferous |
|
architecture |
plant |
Having several, loosely clumped, principal stems that arise from a common underground stem system, each distinct above ground level. |
|
synandrous |
|
architecture |
flower, androecium |
Having the stamens connate. |
|
spinose 1 |
|
apex |
|
Terminating in a rigid, tapering, sharp continuation of the central primary vein. See also spinulose. |
|
gynomonoecious |
|
reproduction |
taxon |
Having all plants with both bisexual flowers and pistillate ones. |
|
terminal |
|
insertion |
|
Apical and with the same developmental axis as the whole, of which it is the distalmost portion or appendage. |
