width, each lobe with a strong median nerve and often two lateral 
ones, lo mm. long, 5 mm. wide, acute; corolla scarcely exserted, 
curved, pubescent outside only to half its length, but distinctly and 
prominently nerved, entirely glabrous inside; ovary ovate, glabrous; 
style distinctly articulated near the ovary, pale brown and swollen at 
the base (obclavate), and hirtulose in the upper three fourths.

The variety stylopiihens differs from the species in many ways, but 
especially in the obclavate pubescent style, almost hidden corolla, in 
the short peduncle, and large calyx lobes. The leaves are not cordate 
but rounded at the base. The ovary, instead of being oblong and 
continuous with the style, is ovate and constricted at the base of the 
articulate style. The plant is almost worthy of specific rank. 
Cyrtandra platyphylla stylopubens forma ovata Rock n.f. 
Leaves ovate-oblong, acuminate, subglabrous above, with a scat- 
tered pubescence underneath, especially along midrib and veins, the 
margin serrate, often coarsely serrate to near the contracted base; 
inflorescence as in the preceding; calyx thin, membranaceous, green, 
pubescent outside, glabrous inside, the lobes strongly one-nerved; 
corolla slightly protruding, the lobes larger and rounded ; fruit oblong, 
the calyx persistent and enclosing the fruit, but the lobes deeply cut 
to near the base when with fruit.

This form of variety stylopubens differs from the latter in the oblong 
leaves, and in the larger calycine lobes which are glabrous inside; the 
leaves are coarsely serrate to near the base. 
Cyrtandra platyphylla parviflora Rock n. var. (See PI. XX H) 
A shrub 3-4 m. high; leaves large, 25-28 cm. long, 10-14 cm. wide, 
thin, chartaceous, bluntly serrate to denticulate, ovate-oblong, acumi- 
nate at the apex, acute and contracting at the base, dark green above, 
very sparingly hirtulose, pale yellowish-brown beneath, finely and 
densely velvety-pubescent, the pubescence short ; petioles 7-10 cm. long ; 
inflorescence a three- to five-flowered cyme, hirsute with brownish- 
yellow multicellular hairs; peduncle about 2.5 cm. long, bibracteate at 
the apex, the bracts linear-oblong, distinctly three-nerved, 2-2.5 cm. 
long, 4-5 mm. wide, the pedicels 12-25 mm. long; calyx, including the 
lobes, I cm. long, the lobes lanceolate, acuminate, of unequal length, 
hirsute outside, glabrous inside; corolla small, the tube cylindrical,
