APOSTASIACEZ OF THE MALAY PENINSULA. 331 
CALANTHE ? GicanrEA, Hook. f., Fl. Brit. Ind., v. p. 856. 
Hab. Perak: Wray, King’s Collector. 
I know nothing of this. 
C. (§ Prepranrue) rupens, Ridl. in Gard. Chron. (1890) 
I. p. 576. 
Hab. Lankawi Islands: C. Curtis! 
There are several forms of this, varying in colour from white, 
or cream, to deep rose colour. It is, however, very distinct in 
size and form of lip from C. vestita, Wall. 
ARUNDINA, Blume. 
A. spectosa, Blume, Bijdr., p. 401, t. 73. 
A. bambusifolia, Lindl. in Wall. Cat., n. 3751. 
A. densa, Lindl., Bot. Reg. (1842) Misc., p. 25, t. 38. 
A. densiflora, Hook. f., Fl. Brit. Ind., v. p. 857, sphalm. 
Hab. Johore: Gunong Janeng, Kelsall ! 
Malacca: Mt. Ophir, abundant ! 
Pahang: River Tahan! 
Perak: Kinta ! 
The Singapore locality given in ‘FI. Brit. Ind.’ must be an 
error. The plant only occurs in the higher mountain districts, 
growing on rocks or gravelly islets in streams, and there is no 
such locality in Singapore. 
A. revoLuta, Hook. f., Fl. Brit. Ind., v. p. 858. 
Hab. Perak: On rocks at the waterfall, Thaiping ! 
A very small-flowered species. The sepals and petals are 
pale rose coloured, the lip rosy pink, darkest at the apex, with 
some yellow in the disc. 
A. cHrvensis, Blume, Bijdr., p. 402 ? 
Hab. Kedah Peak: on rocks, often precipitous. Flowers 
white with brown streaks and a yellow patch on the lip. 
I am very doubtful as to what Blume’s plant is. The Hong- 
Kong plant, commonly called A. chinensis, is A. Philippi, 
Reichb. f., with only three elevated ridges on the lip. The 
Kedah plant is quite different, but I can only see three really 
thickened nerves on the lip, instead of five lamellate ones. The 
flowers are rather bigger than those of A. Philippii, and quite 
different in colour.
