septate 1 |
> trabeculate |
architecture |
|
Having one or more septa. |
chamber (not recommended) |
= cell (not recommended), locule |
FEATURE |
|
Any structurally distinct compartment within an anther, ovary, fruit or other organ; not necessarily having any evolutionary integrity. |
cane |
< culm, stem |
STRUCTURE |
|
A woody, aboveground culm. Use of this term or culm instead of stem is a matter of tradition and preference, not of descriptive precision or necessity. |
strobilus pl. strobili |
= cone; > female cone, macrostrobilus (not recommended), male cone, megastrobilus, microstrobilus |
STRUCTURE |
|
A compound or complex reproductive structure consisting of a central axis bearing congested sporophylls and sometimes other lateral members (e.g., bracts) that are sterile. |
angled |
|
solid shape |
|
Having sides that meet at acute or obtuse angles. |
rachis 2 var. rhachis |
|
STRUCTURE |
|
A main or first-order axis of an inflorescence. |
moniliform |
= beaded |
solid shape |
|
Elongate, relatively slender, transversely round, and more or less regularly constricted over its length, the whole straight or variously curved; like a necklace of beads. |
verticil |
= cycle, series, whorl |
STRUCTURE |
|
A set of three or more lateral structures that are inserted around an axis at the same level. |
goblet-shaped |
= crateriform |
solid shape |
|
Having a distal, concave, relatively thin-walled, basically hemispherical portion surmounting a much narrower, transversely round, pedestal-like base. |
spiculate |
|
relief |
|
Having small, fine, stiff, acute protrusions that resemble little spikes. See also scabridulous (scabrellate, scabrellous, which is not clearly distinct in its application. |
cone |
= strobilus; > female cone, macrostrobilus (not recommended), male cone, megastrobilus, microstrobilus |
STRUCTURE |
|
A compound or complex reproductive structure consisting of a central axis bearing congested imbricate sporophylls and sometimes also sterile bracts. |
plantlet |
|
STRUCTURE |
|
A juvenile, complete plant produced asexually by budding, as from the leaf margin in some Kalanchoë (Crassulaceae); this term is usually applied only while such vegetatively produced offspring remain attached to the plant of origin. |
dolabriform |
= axe-shaped |
solid shape |
|
Elongate, basally terete, becoming strongly compressed toward an abruptly and unilaterally broader apex; like an axe (handle plus head). This term is not semantically distinct from dolabrate, but botanically they have had somewhat different applications. |
leptosporangiate |
|
reproduction |
|
Having relatively small sporangia each of which develops from a single initial cell that, by periclinal division, gives rise to an outer and an inner cell, the former then giving rise to the entire sporangium, including contents and sporangiophore, the latter contributing nothing to it; in some Polypodiophyta. |
basicaulous |
|
position |
|
At or very near the stem base. |
hilum 2 pl. hila |
|
FEATURE |
|
The more or less central point within a starch grain of intracellular origin, about which the successive layers of starch were accreted more or less symmetrically. |
crusty |
= crustaceous |
texture |
|
Thin, dry, hard, and brittle. |
puckered |
= blistered, bullate, pustulate |
relief |
|
Having relatively coarse, irregularly disposed, rounded protrusions or convexities resembling blisters. See also papillate, papillose. |
episepalous |
|
position |
|
Upon the sepals, or partially adnate thereto and apparently arising therefrom. |
megaphyll |
= leaf, macrophyll (not recommended); > frond, needle |
STRUCTURE |
|
A principal, vegetative shoot organ borne laterally from a stem node; its vascular tissues, if any, continuous with those of the stem; undergoing no significant secondary growth; usually more or less bilaterally symmetrical; comprising a distal, usually laminar blade and/or a proximal stalk (petiole) or sheath; usually a primary site of photosynthesis. |
seed coat |
= testa |
STRUCTURE |
|
The outer protective layer of a seed, developed from the ovular integument(s). |
geminate |
= conjugate, paired |
arrangement |
|
Inserted by pairs, the members of each fused or not. |
papilliform |
= papillar(y) |
solid shape |
|
Small, conoidal, and protruding from a larger structure; resembling a pimple; esp. trichomes. |
integument |
|
STRUCTURE |
|
A distinct layer of tissue that encloses and serves to protect the other tissues of an organ, especially a seed. |
supple |
= flexible, pliable, pliant |
texture |
|
Able to bend over its length and/or breadth without structural disruption. |
