The following cultivars of Hibiscus rosa-sinensis were obtained from a local supplier and grown under greenhouse conditions; 'President' with

cordate leaves densely packed along the shoot and red full double blooms.

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,
