RIDLEY. 
3. H. microcheila Ridl. 1. c. 006. 
Stems from 1 to 3 m tall, several in a somewhat scattered cluster, 
recurved or drooping, yellowish-green, rigid, less than 1.5 cm thick, 
except the reddish, very much enlarged bulbous bases. Leaves subcoria- 
ceous, linear-oblong, cuspidate, 20 to 24 cm long, 5 cm wide, glabrous on 
the upper surface, the midrib pubescent beneath, margins glabrous, 
reddish-brown; petiole 1 cm long, puberulous; ligule oblong, rounded, 
half as long as the petiole; sheath pubescent above, reticulate. In- 
florescence small, ovoid, 4 cm long, on a peduncle about as long, which 
is covered with ovate, ribbed, pubescent bracts. Inflorescence-bracts few, 
ovate, the largest 3 cm long, 1.5 cm wide, coriaceous, ribbed, pubescent, 
red, mucronulate, the margins thinner, ciliate. Ovary glabrous, with a 
tuft of silky hairs at the top. Calyx tubular, 4 cm long, with a few silky 
hairs at the base, glabrous above except for the two acuminate lobes which 
bear tufts of hairs. Corolla pink, the tube 5 cm long, the upper lobe 
ovate-oblong, obtuse, 7 mm long, the lower ones narrower, linear-oblong. 
Lip creamy-white, 1 cm long, with two short narrow lobes, as long as the 
anther, base narrow, the sides upcurved and terminated by a rounded 
crisped limb; disk at base sparingly silky-hairy. Anther very short, 
glabrous, refuse at the tip. Stigma large, club-shaped. 
Negros, Cuernos Mountains, near Dumaguete, Elmer 10279, near the river at 
an altitude of about 900 in. The smallest-flowered species of the section, and 
remarkable for its white lip, which is unusual in the genus. 
Endemic. 
4. H. lophophora Ridl. 1. c. 607. 
Stems 6 m tall, 3 cm thick, the bulbous base 12 cm in diameter. 
Leaves lanceolate, oblong, slightly narrowed at the broad base, 69 cm long, 
15 cm wide, glabrous on the upper surface, beneath silky-velvety, the 
midrib prominent, silky ; petiole 2 cm long, but the blade decurrent to the 
base; ligule 1 cm long, covered with tufts of silky hairs, arranged in 
transverse lines. Sheath striate, with small, round or linear pustules, 
each bearing a tuft of silky hairs. Inflorescence clustered, scarlet, on 
peduncles 1 cm thick, covered with silky hairs. Spike 4 to 5 cm long, 
ovoid. Bracts ovate, acute, pungent, glabrous, red, longitudinally striate 
with rather high narrow ridges, with a line of pustules or transverse 
bars between each rib, the inner bracts lanceolate. Flowers not seen. 
Fruits glabrous, 2 cm long, flattened, elliptic, beaked, bearing the remains 
of the calyx, finely ribbed, tliin-walled, with numerous oblong to pyriform 
seeds which are irregular in form, but usually truncate, 2 mm long. 
Negros, Cuernos Mountains, near Dumaguete, Elmer 10365, in fertile glens at 
an altitude of about 1200 m. 
As a rule it is not advisable to describe a Hornstedtia as new, without seeing 
the flowers, but an exception may be made in the case of this curious species. 
The peculiar sheath and ligule, as well as the small flattened fruit, is quite 
unique in the genus. In some of the islands of the Eastern Archipelago, species 
are found in which the leaf-sheaths are not only ribbed longitudinally, but also
