Of 4 Benguet plants collected, two have male flowers only, one female flowers 
only, the fourth has flowers of both sexes, nearly always in different inflorescences. 
The plants are somewhat intermediate between the above species and U. thunberg- 
iana Sieb. & Zuce., as is also Kawakami 779, from Formosa; the latter, however, 
shows the northern alliance, while the Philippine agrees more closely with the 
Malayan species. Its stipules are ovate, 9-13 mm long, 7-8 mm wide, more or 
less auriculate at the base. The Formosan plant is herbaceous and more slender 
with quite different stinging hairs; the leaves of both are doubly serrate. 
Weddell * prefers Miquel’s specific name to that of Blume, reducing the much 
older U. grandidentata of Moris to U. atrovirens Rep. in Loisel. Nouv. Not. (1827)
