ENUMERATIO SPECIERUM ASIATIC ARUM.

 Petersbourg, ser. 7, IV. No. XI. 3 {Rhamn. Or.-As.) (1866). — Schneider, III.

5. Berchemia flavescens Brongniart in Ann. Sci. Nat. X. 357 (M4m. Fam. 

 Rhamn. 50) (1826). — Lawson in Hooker f., Fl. Brit. Ind. I. 637 (1875). 



Zizyphus flavescens Wallich in Roxburgh, Fl. Ind. II. 367 (1824). 



Himalaya: Nepal, Sikkim. 



To this species may possibly belong Faber's No. 199 from Szech'uan, Mt. 

 Omei. Wallich's description agrees very well with Faber's plant, but I have 

 seen only a rather scanty flowering specimen of the type. Hooker says: " Young 

 branches with black spreading deciduous hairs," what I think is an error, the 

 " hairs " upon the twigs of the plant before me being the product of a fungus. 

 Our Chinese form needs further study. 



6. Berchemia sinica Schneider. See p. 215. 



7. Berchemia cinerascens Blume in Miquel Fl. Ind. Bat. I. 1, 644 (1855). — 

 Koorders, Excursionsfl. Java, II. 553 (1912). 



Rhamnusl cinerascens Blume, Bijdr. 1141 (1826). 



Western Java. 



Of this species I have seen one specimen with a few very young flowers. Koord- 

 ers reproduces only the very short description of Blume. This species is probably 

 correctly referred to Berchemia and may be closely related to the following 

 species.
