Historically, the first reference to Arundo arbor tenuis is 

 found in Loureiro's Flora Cochinchinensis (1790) 58, where he 

 refers it to his Arundo multiplex. However, Arundo multiplex 

 Lour, was primarily based on specimens from Cochin-China and 

 of course must be interpreted from Cochin-China material. It 

 is Bambusa multiplex Raeusch, a species of doubtful status, 

 which Munro suggests closely approaches Bambusa nutans Wall. 

 Willdenow erroneously referred the Rumphian species to his 

 Bambusa verticillata, Sp. PL 2 (1799) 245, in which he was 

 followed by many authors. Willdenow's species, however, was 

 based on actual specimens, has nothing to do with the Rumphian 

 plant, and is Gigantochloa verticillata Munro. All of the 

 synonyms cited above, except Bambusa rumphiana Kurz and 

 B. lineata Munro, have previously been considered to represent 

 species of doubtful status. 



Var. AMAHUSSANA (Lindl.) comb. nov. 



Bambusa amahussana Lindl. in Penny Cycl. 3 (1835) 357 (type!). 

 Bambusa rumphiana Kurz, var. amahussana Gamble in lit. 

 Arundarbor amahussana (i. e. Leleba amahussana) Rumph. Herb. 

 Amb. 4: 3. 



Amboina, Amahoesoe, Robinson PI. Rumph. Amb. 35, July 30, 1913, near 

 the beach, 2 to 3 m high, often reclining, locally known as bambu nitu. 



Regarding this form Mr. Gamble writes as follows: "No. 35 

 is identified, with much probability, with Arundarbor tenuis 

 amahussana. It comes from Amahoesoe and differs from the 

 others in the small spikelets. It is, I think, quite a distinct 

 variety, but only a variety, for dissection of the flowers pre- 

 sents no differential characters. It is characterized by its very 

 small spikelets." 



In connection with the various forms of this species it is 

 well to note that Kurz* has enumerated five varieties under 

 the Malayan names, Leleba dyahat, pootee, ietam, tootool, and 

 soorat. 



BAMBUSA VULGARIS Schrad. in Wendl. Collect. PI. 2 (1810) 26, t. U7. 

 Bambusa fera Miq. PI. Ind. Bat. 3 (1855) 418 (type!). 

 Bambusa vasaria Munro in Trans. Linn. Soc. 26 (1870) 122 (type!)? 

 Arundarbor fera Rumph. Herb. Amb. 4: 16, t. 

 Arundarbor vasaria s. Bulu Java Rumph. Herb. Amb. 4: 8? 



Arundarbor fera Rumph. is the whole basis of Bambusa fera 

 Miq., and it seems to be typical Bambusa vulgaris Sclirad., a 

 disposition of it suggested by Miquel. Loureiro, FL Cochinch. 

 (1790) 57, referred it to Arundo mitis Lour., a species typified
