 Amboina, Batoe merah, Robinson PI. Rumph. Amb. 36, August 11, 1913; 

 Lateri, Robinson PI. Rumph. Amb. 37, August 26, 1913, locally known as 

 bulu jawa and bulu seru, in dense clumps, culms from 5 to 10 meters high, 

 the internodes 35 to 90 cm in length. 



In regard to the numbers cited, Mr. Gamble writes as fol- 

 lows: "I think that you have correctly identified these with 

 Arundarbor cratium. The specimens are quite good ones of 

 Schizostachyum brachycladum Kurz, and agree with a series 

 of specimens from Java and the Philippines as well as with 

 specimens from cultivated plants in the Calcutta garden." 

 Loureiro, Fl. Cochinch. (1790) 58, referred Arundarbor cratium 

 to Arundo fax Lour., a species based on Cochin-China specimens 

 and probably not the same as the Amboina form. Melocanna 

 humilis Roep., ex Trin Clav. Agrost. (1822) 105, is merely 

 a new name for Arundo fax Lour. Beesha humilis Kunth, 

 Enum. 1 (1833) 434, and Beesha fax R. & S., Syst. 7 2 (1830) 

 1336, are also synonyms of Arundo fax Lour, and like Loureiro's 

 species are not to be interpreted by the latter's erroneous reduc- 

 tion of Arundarbor cratium Rumph. Rumphius briefly describes 

 six forms following Arundarbor cratium, but the descriptions 

 are not sufficiently definite to warrant the reduction of any 

 of them. They may or may not be variants of Schizostachyum 

 brachycladum Kurz. See also under Schizostachyum sp. 

 (Bambusa longinodis Miq.).

Miquel's species was based wholly on Rumphius, as he speci- 

 fically includes from Bambusa tabacaria Poir. {Arundo taba- 

 caria Lour.) only the reference to Rumphius. Loureiro, Fl. 

 Cochinch. (1790) 68, quotes Rumphius's species as a synonym 

 of Arundo tabacaria Lour., a species based on Cochin-China 

 specimens undoubtedly different from the Amboina plant; Bam- 

 busa tabacaria Poir. is merely a new name for Loureiro's species 

 and must be interpreted from Loureiro's description, not from 

 Rumphius. Bambusa longinodis Miq. is unquestionably a 

 species of Schizostachyum closely allied to the Philippine 

 Schizostachyum lima (Blanco) Merr. (S. hallieri Gamble) and
