1 mm of the petiole, glabrous with matt appearance, leaf blades (6-)10-16(19) cm long, (2-)6-13(-15) cm wide, dimorphic through the sympodial axe, monopodial leaves ovate to broadly ovate, slightly to deeply cordate
at the base, with the lobes slightly asymmetrical; sympodial leaves oblong-lanceolate to elliptic, obtuse to round, almost symmetrical at the base; moderately to long acuminate at the apex; non-ciliate at the margin, glabrous or with occasional minutely hairs on both surfaces; palmately nerved, veins (3-)5-7(-9); non-membranaceous, with lustrous appearance.
concolor antheridia has been observed prior to the adult cordate
, extending posteriorly between coxae 4.
Shape of base of involucral bracts: 0, cuneate; 1, cordate
Its leaves are cordate
and membranous with bark spiraling left appearing gray or creamy.
8 cm long; extrafloral nectaries absent; leaflets 6-7 pairs, papyraceous, pilosulose, 33-73 x 17-25 mm, lanceolate, oblong to oval, elliptical, venation brochidodromous, nervures 11-18 pairs, apex acute and obtuse-mucronate, base rounded and cordate
, margin revolute, glabrous.
The following cultivars of Hibiscus rosa-sinensis were obtained from a local supplier and grown under greenhouse conditions; 'President' with cordate
leaves and red full blooms, 'Joanna' with ovate leaves and orange cartwheel overlapped single bloom with a dark orange eye zone, and 'Double Red' with cordate
leaves densely packed along the shoot and red full double blooms.
5 cm, cordate
to subtruncate at base; lobes broadly ovate, entire, obtuse to subacute at apex; cauline leaves absent or 1, petiolate, much smaller than basal leaves.
Regeneration of single cells isolated from cordate
gametophytes of Pteris vittata.
The fruit is obovate in face view, cordate
basally and apically, with a smooth, fusiform endocarp, capped by remains of the perianth and style.
Shell plano-convex, slightly cordate
in outline, varying from subquadrate in small shells to suboval in adults (Fig.
aureum (C4) had large involucel bracts, which were ovate or circular, and large cauline leaves, amplexicaul at base, cordate
or with large ligules.
