- Diagnosis
- Leaf lobate-palmate, stipulate, with a basal
leaflet distinct, the rest increasingly fused over the leaf.
Leaflets linear-lanceolate, about 404 mm, acutely
pointed. Midrib prominent, secondaries thin, faintly
marked, eucamptodromous, joining intramarginal
vein. Stipule sheathing ovate-lanceolate, parallelveined,
with free part triangular, 1 mm long. Leaf
compression thick, with stomatal pits distinct at low
magnification, and with transverse striation reflecting
pallisade mesophyll structure. Leaf blade hypostomatic,
with hair bases and large spherical glands
(Figure 9B) on both sides. Secondary veins scarcely
reflected in the epidermal cell patterns. Ordinary
epidermal cells polygonal, irregularly disposed or
radiating from a larger, rounded cell. Stomata scattered,
irregularly orientated, anomocytic to weakly
cyclocytic, with typically five trapezoid subsidiary cells
that are slightly sunken below the level of ordinary
cells. Some guard cells show long, T-shaped polar
thickenings. Hair bases small, elliptical, encircled by a
variable number (up to ten) epidermal cells.
