Tribe XI. BAMBUSEJS. (See p. 91.) 

 By J. S. GAMBLE, M.A., F.L.S., Conservator of Forests, N.-W. Provs. 



The following account of the Indian Bambusece is drawn up, almost verbatim, 

 from Mr. Gamble's " Bamboos of British India," which forms part of vol. vii. of 

 Dr. King's ' Annals of the Royal Botanic Gardens of Calcutta," and of which Dr. 

 King favoured me with a copy in advance, together with his and Mr. Gamble's 

 permission to reproduce its contents in a form suited to the " Flora of British India." 

 In doing this F have been obliged to curtail the descriptions. And in order to 

 preserve the arrangement of matter adopted in this work, I have had to substitute 

 for the Keys to the species employed by Mr. Gamble, specific characters selected 

 according to my judgment from his detailed descriptions ; and in a few cases to 

 substitute synonymous technical terms for those he has used. I have added 

 nothing ; for it is obvious that a botanist of Mr. Gamble's ability and wide ex- 

 perience of so many of the Indian Bamboos in their native forests, having access also 

 to the unrivalled collections in the Herbarium of the Calcutta Gardens, should have 

 exhausted the subject in so far as materials were available. It must not be supposed 

 that this work supersedes his " Bamboos of British India," which is indispensable to 

 the student of the tribe, by reason of its fuller descriptions, and admirable plates and 

 analyses. My cordial thanks are directly due to Dr. King and Mr. Gamble for this 

 generous contribution to the " Flora o British India," and indirectly for the 

 authentically named collection of specimens corresponding to Mr. Gamble's descrip- 

 tions, which has been presented by the Government of India to the Herbarium of the 

 Koyal Gardens, Kew. 



Since the above was written, Mr. Freeman Mitford's " The Bamboo Garden" 

 has appeared, a work replete with valuable observations upon the habit, mode of 

 growth, and other characters of the hardy species of Bamboo (including 5 Indian) 

 cultivated by him. In it is pointed out (see sJrundinaria Simoni, p. 60) for the
