Geographical distribution: O u t s i d e J a v a : unknown. 

 In Java: Only in Western Java, in the Preanger, at an altitude 

 of 1000 — 2000 m. Here only represented by two collecting numbers 1) 

 in virgin forest, probably in 1839 on or near the plateau ofPenga- 

 lengan (Junghuhn n. 143, in Herb. Lugd. Bat. sub n. H. L. B. 908, 

 7—617—618—619—620. — branches which only bear leaves) and 

 2) in the Wajang-Windoe mountains, near the tea-plantation Malabar 

 in virgin forest, at a height of 1600 m. above sea-level (A. Pui.le 

 n. 3173 in Herb. Rheno-Traject. .Sutfruticose, climbing, 10 m.- high. 

 Spikes dark violet. Flowering without leaves. This species of Bamboo 

 has not tlowered for a xery long time, according to verbal information 

 obtained locally. Flowering branches collected on June 25, 1906). 

 — Native name: Awi-eueu or Awi-eueul (Sundanesej near 

 Pengalengan. 



This species is phyto-geogra])hically xQYy interesting, because 1) 

 this monotype represents a genus, which according to Gamble (see 

 above), is more nearly related to the genus Sasa Shibata, occurring 

 in Japan, but absent from the Malay Archipelago, than to the other 

 genera of Gramineae-Bambuseae, represented in the Archipelago by 

 numerous wild species ; 2") because in Java, according to my numerous 

 journeys, nearly all wild-gi'owing Bambusaceae only occur below 

 1()00 m., while Oreiostachi/s Ptdlei Gamble, was found growing wild 

 by PuLLE 1600 m. above sea-le\el, 3) because this species appears 

 to be endemic in Java, and seems there to be localized in a few 

 mountain regions of the Preanger.
