STRUCTURE |
|
An aggregate of follicles produced from a single flower with multiple simple pistils. |
|
sporophyll |
= spore leaf; > fertile frond |
STRUCTURE |
|
A leaf or homologous structure that bears sporangia. See also megasporophyll (macrosporophyll, not recommended), microsporophyll. |
|
cap cell |
|
STRUCTURE |
|
The single cell, or one of the several cells, forming the uppermost (distal) portion of an antheridial wall. |
|
circumcaulous |
|
insertion |
|
Upon and surrounding the stem. |
|
…lobate |
? …cleft, …fid, …lobed, …parted, …partite, …segmented |
solid shape |
|
Having the number of lobes indicated by the prefix; as in bilobate. |
|
fan-shaped |
= flabellate, flabelliform |
solid shape |
|
Strongly compressed, broadest near the apex and attenuate to a narrow base, plaited longitudinally, the alternating folds radiating from the base, the whole basically triangular in broad aspect; like a partially expanded folding fan. |
|
septate 1 |
> trabeculate |
architecture |
|
Having one or more septa. |
|
granuliferous |
= powdery, pulverulent |
coating |
|
Covered with a more or less even deposit of fine, dry particles. See also lentiginous (dusty, lentiginose), which is not clearly distinct in its application. |
|
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. |
|
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. |
|
rachis 2 var. rhachis |
|
STRUCTURE |
|
A main or first-order axis of an inflorescence. |
|
contortuplicate 1 |
= torsive |
aestivation |
|
Plicate and contorted. |
|
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. |
|
aestivation |
|
CHARACTER |
|
Disposition of perianth (undifferentiated), calyx, or corolla members in the bud. |
|
flesh |
|
STRUCTURE |
|
Tissue that is fairly firm and dense, juicy or at least moist, and easily cut. |
|
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. |
|
barbed 2 |
|
solid shape |
|
Having one or more relatively short, stiff, acutely inserted or bent, antrorse or retrorse, terminal and/or lateral hook-like appendages; esp. awns or setae. |
|
crusty |
= crustaceous |
texture |
|
Thin, dry, hard, and brittle. |
|
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. |
|
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. |
|
angled |
|
solid shape |
|
Having sides that meet at acute or obtuse angles. |
|
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. |
|
puckered |
= blistered, bullate, pustulate |
relief |
|
Having relatively coarse, irregularly disposed, rounded protrusions or convexities resembling blisters. See also papillate, papillose. |
|
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. |
