Both of Blanco’s descriptions manifestly apply to the same
species, and Rhamnus tatonai Blanco has page priority. The
form that I described as Zizyphus arborea, is the same arid must
be reduced. Fernandez-Villar erroneously reduced the former
to Zizyphus oenoplia Mill, and the latter to Z. xylopyrus Willd.,
both manifestly erroneous reductions. Thè species is widely
distributed in the Philippines, the leaves varying from entirely
glabrous to rather prominently pubescent. As to Rhdmnus fiato-
nat Blanco, his description, while short, applies unmistakably
to the form as here interpreted and to no other %nown Philip-
pine representative of the genus. Blanco’s specimens were from
San Mateo, Rizal Province, Luzon, a region thoroughly well
known botanically; the Tagalog name talanai, cited by Blanco,
seems to be no longer in use.
Illustrative specimen from Umingan, Pangasinan Province,
Luzon, May, 1914 (Merrill: Species Blancoanae No. 12).
