However, these differences are unrealistic, and he recognized both auriculate
and non-auriculate forms in L.
When present, apical pinna is lanceate, with attenuate apex, enlarged base, often incised, divided or lacerated; lateral pinnae 25-30 (35) pairs, 4-8 cm long x 1-2 cm wide, lanceolate to triangular-lanceolate, almost horizontal, contiguous to imbricate, briefly petiolulate, with an acute apex, a symmetric or asymmetric base, often auriculate
and overlapping the rachis, crenate and subtly serrulate, papillate margins.
Leaves ovate-triangular to lanceolate, acute, with a decurrent narrow base, sometimes slightly auriculate
, 1.5-3.0 mm long.
However, all species of series Otopteri examined in this study have auriculate
Florets dimorphic; marginal florets female, without staminodes, corolla sub-bilabiate (3+1 corolla lips), tubular-funnelform four- to five-lobed, rarely bilabiate; central florets male with a rudimentary ovary, corolla tubular-funnelform, deeply five-lobed; anther apical appendages rounded to acute at the apex, basally constricted and demarcated from the thecae, basally auriculate
with tails very short, smooth; style bilobed, branches dorsally papillose.
Sheaths glabrous, with prominent nerves, margins auriculate
. Ligule a membranous rim, the tip laciniate, 1.5-2 mm long, truncate, glabrous.
Leaves alternate, rarely basal leaves rosulate; petiolate, sessile, decurrent to auriculate
; blades linear, elliptic to ovate, pinnately veined, margin mucronulate to serrate, sometimes revolute, pubescent.
is characterized by having yellow flowers, strongly 2-lobed stigmas, often pinnately divided but never auriculate
or amplexicaul cauline leaves, and simple or no trichomes.
Leaves alternate, often rosulate; sessile, often auriculate
at the base; blades linear to elliptic, margin entire to denticulate, usually tomentose on the lower surface.
Leaves sessile, at least upper ones auriculate
to amplexicaul; septum absent; filaments glabrous S.
