THE FLORA HONGKONGENSIS. 137 
lower glumella, I can find nothing to distinguish the Kordofan 
E. tremula, Hochst., from E. orientalis. E. bahiensis, in its usual 
state, has, with its compactly arranged deep-coloured wider spike- 
lets, a greater resemblance to E. megastachya, Link, than to E. 
orientalis; but I have found specimens which I could not satis- 
factorily refer to one rather than the other. And even so emi- 
nent an authority as General Munro seems to have been beset by 
similar difficulties ; for a specimen of mine labelled in his hand- 
writing E. zeylanica, and enumerated as such in the * Botany of 
the Voyage of the Herald,’ is certainly only Æ. dahiensis, a species 
Which, by the way, is not mentioned in that work. 
*Arundinaria sinica, Hance in Ann. Sc. Nat. Par. scr. 4, xviii. 235. 
(=A. Wightii, Benth. Fl. Hongk. 434, but not 4. Wightiana, Nees. 
— A. longiramea, Munro in Trans. Linn. Soc. xxvi. 19.) 
Not known out of the island. My name has several years’ 
priority over that of Munro. 
*Dendrocalamus latiflorus, Munro in Trans. Linn. Soc. xxvi. 152, t. 6. 
(= Bambusa verticillata, Benth. Fl. Hongk. 434, but not of Willdenow.) 
Only found hitherto in China and in Formosa. This fine spe- 
cies, the * Great Bamboo of the Chinese, which has culms about 
40 feet high, instead of 7 as stated by Munro, flowers, favente 
Jove, annually without dying down or being apparently weakened. 
It is the species generally employed here for scaffolding and where 
strong large-sized stems are required; and its young shoots are 
extensively used as a vegetable. 
*Bambusa tuldoides, Munro in Trans. Linn. Soc. xxvi. 93. (= D. tulda, 
Benth. Fl. Hongk. 434, but not of Roxburgh.) 
Oceurs also on the adjacent continent and in Formosa. 
60. Bambusa flexuosa, Munro in Trans. Linn. Soc. xxvi. 101. 
Not so common in Hongkong as on the continent, but found 
here and there. Not known out of China. A curious and distinct 
species, forming dense clumps, apparently flowering less regularly 
than Dendrocalamus latiflorus, but also not dying afterwards. 
Both flower in the winter months. 
Having to add fifteen ferns to those enumerated by Mr. Ben- 
tham as inhabiting Hongkong, and the generic nomenclature I 
should employ not being consonant with that of the flora, I am 
compelled to reduce the whole of the species in that work to an 
harmonious system. To this end I have, so far as possible, endea- 
voured to name them according to the views of the late Professor
