in so many points with Blume’s description and figure that in , spite of the 
improbability of a Javan species being isolated in the Benguet region, the only 
characters upon which to base a separation are of such a nature that they can 
merely be discussed. Blume founded the genus Leptocnide, of which this species 
is the type, on the ground that the perianth is adnate to the ovary: Weddell 
evidently disbelieved this, or he would not have transferred the species to 
Pouzolzia. In the Philippine specimen, the perianth closely surrounds the ovary, 
but is not adnate to it, so far as can be determined from dried material. The 
leaves of the Philippine plant average smaller than those of the Javan, but 
attain a length of 4 cm, the color-notes hold good, so far as cam be judged, 
the arrangement described for the flowers is probably also true, but many of the 
staminate have fallen.

The Philippine specimens of this polymorphic species show many variations, 
usually corresponding to those found in other countries, but with some addi- 
tions. As the study of our material and of the literature has led me to the 
conclusion that they should be included under one species, the oldest specific 
name applied to it has been used. However, if the species were to be divided, 
it is probable that all of our plants would go rather with typical P. indica than 
with any of the varieties kept distinct as such by Weddell. The fruiting perianth 
has from 8 to 12 ridges, usually blunt, sometimes more acute, rarely rather faint. 
The chief variants are briefly discussed. 
The Mindanao collections differ considerably from the others. One of the Zam- 
boanga plants has unusually large, broadly lanceolate, opposite leaves; another is 
procumbent with small alternate, orbicular-ovate leaves, and the typical fruiting 
perianth of P. indica. The Apo and Lanao collections are alike and much more 
pubescent than any of the others, except in this and size they agree with those 
from Port Banga, all having the perianth-ridges weakly developed: about an 
equal number of the staminate flowers are pentamerous and tetramerous. The 
Casiguran specimen is remarkable for its height, about 3 m, and still more for 
the shining black achenes.
