32 COLONEL MUNRO'S MONOGRAPH OF THE RAMRUSACEE. 



I have scon only one spcH-inicii of tliis, collected by iliiids; and it seems curious that 

 so conspicuous a plant should not have atti'acted the attention of other collectors. The 

 very narrow, dark-coloured, conspicuously tessellated leaves at once distinguish it from 

 J. lovffiramea, the only other species of Ariiiidinarki which I have seen from Hong- 

 kong. It does not closely resemble aiiy Arimduiaria I am acquainted with.

This may possibly be a peculiar state of A. Wulkei'loua, as I have already suggested 

 in de.scril)ing that species at p. 22. I think, however, that the absence of cilia (which 

 are generally more conspicuous in young than in old states of Bamboo), the extremely 

 small leaves with such very long points, the absence of any distinct secondary nerves, 

 and the occasionally obscure tessellation of the leaves, allbrd good marks of distinction.

Griffith, in his account of his journey from Assam to Bootan, constantly refers to this 

 plant as growing at considei'able elevations, and "forming large patches in wet places." 

 In describing the vegetation of the Dhonglaila Pass, he says, "the sward commences at 

 10, (100 feet, and is conunon at 1)500, where it is principally clothed with i\\G Bat)ibiisu 

 )ii)(:)-opli>jll(i." This and the preceding species have the smallest leaves of all the Bamboos
