Mandaville also remarked that a species of tulip with undulate leaves does exist 'which thus might appear crenate
if viewed from a certain angle.
6 mm long, 4- or 5-celled, acicular, ascending to strigose, light brown; basal basiscopic pinnules of medial pinnae not enlarged or overlapping the lamina rachis, crenate
to lobate; costules abaxially eglandular, sparsely pubescent, sparsely scaly, the scales ca.
The leaf margin is always toothed, with generally crenate
Margin: (0) serrate; (1) crenate
, or dentate, with one order of teeth; (2) dentate in two orders; (3) dentate in three or more orders; (4) dentate with secondary akroteria as broad, first-order teeth, the margins of which bear higher-order akroteria that resemble teeth in venation but lack sinuses; thus the margin of the broad, first-order teeth is essentially repand; (5) entire.
3 mm, set 45-90[degrees] to the rachis, each spaced 1-2 times its width, linear-lanceolate, oblong to linear, the bases decurrent basiscopically, straight or nearly so acroscopically, pinna margins entire (sterile) to undulate or slightly crenate
(fertile), the apices rounded (sterile) to subacute (fertile); veins free, pinnate, branched once, not visible without transmitted light; hydathodes lacking adaxially; sori brown, round, 8-12(-18) per pinna, medial to submarginal, 0.
The wings of young gametophytes were one cell thick and were usually flat, but became more curved, ruffled, and irregularly crenate
Only 1 described species, Neoplea notana (Drake & Chapman 1953), does not have a defined dorsal lobe, but instead has a crenate
Species in this genus are terrestrial with creeping rhizomes; petioles with numerous round, vascular bundles arranged in a ring; stems short-creeping to erect; leaves monomorphic, 1-3--pinnate-pinnatifid, gradually reduced distally to pinnatifid apex, herbaceous to somewhat leathery; pinnae not articulate to rachis; segment margins entire, crenate
or serrate; sori round with a peltate indusium; spores brownish, coarsely rugose or with folded wings; and the chromosome number of x = 41 is common in the Dryopteridaceae.
bryopteris is multi- to tri-lobed and the margin of the tip is crenate
and characterized essentially by an entirely yellow-orange corolla with well-developed, divergent, rounded latero-posterior lobes, lanceolate leaves with a narrowed base and crenate
solely in the upper two-thirds, and an indumentum of the stems and vegetative leaves consisting of long, branched, flexible hairs.
