completely and fell about 3,0co feet into the forest at the foot of the 
mountain. Had I stepped on it I should certainly have gone with it. | In 
this species bulbils are borne on the sides of the stems, especially 
after the flowers have been cut. These have a broad base and a leafy stem, 
so that when detached and pushed into the ground they soon become good- 
sized plants. So easy 'is the propagation of this plant that it is much the 
commonest in gardens in the Straits Settlements. The plant also often 
bears more than one raceme at the top. 
A. CHINENSIS, Blume (Bijdr., p. 402), was thought to have been intro- 
duced from China, and has puzzled everyone by the statement that it has 
five keels on the lip, a thing I have seen in no Arundina flower, though in 
dried specimens it is possible to mistake the outer nerves for real keels. 
The Hongkong plant has a remarkably broad, deep crimson edge to the lip, 
and the sepals and petals are pure white. Like A. bambuseefolia, it fails to 
produce bulbils. A. Philippii, Rchb. f., and A. Meyeniana, Rchb. f., are 
probably the same thing. 
A. suBSESSILIS, Rolfe (Kew Bull., 1914, p- 374), differs in having small 
flowers in a compact head. It is a native of Upper Burma, and was 
described from a plant that flowered in the collection of Mr. H. J. Elwes. 
There are several other species. A. minor, Lindl., a native of Ceylon, 
has narrow, coriaceous leaves and small flowers. A. revoluta, Hook. f., 
grows near the Taiping Waterfall, and has narrow grassy leaves and very 
small pink flowers, A. affinis, Griff., is a native of the Himalayas. It has 
narrow leaves and a highly-coloured margin to the lip. Jt may be a variety. 
of A. speciosa. 
DENDROBIUMS FROM STREATHAM.—Two very handsome Dendrobiums 
are sent from the collection of R. G. Thwaites, Esq., Streatham Hill. 
D. Austinii is a brilliant hybrid which was raised in the collection some 
years ago from D. Cybele nobilius X D. Ainsworthii splendidissimum, and 
is excellent both in shape and colour. The flowers sent have an expanse of 
34 inches, and the broad sepals and petals are rich purple with a lighter base. 
The lip, which is over 1} inches across, has a large maroon disc, with a 
broad white zone round it, and a sharply defined purple area in front. D. 
nobile Thwaites’ var. is still larger, and of great substance. The petals are 14 
inches broad, white with bright purple apex, and the lip is 14 inches across," 
white. with a rose purple apex, a large dark maroon disc, and the typical 
nobile shape. The sepals are rather more suffused with rose purple. It is 
a charming thing, and one of the finest forms of the D. nobile nobilius type 
that we have seen. We are not sure of the origin of this fine variety, but 
it Probably came out of some importation of the species, as have two or 
three other exceptional forms.
