160 Mr Yapp , Notes on new and interesting Plants 
Gephaelis stipulacea, Blume, of which I found two or three 
specimens in thick jungle, at an altitude of about 3 to 4 thousand 
feet, has hitherto been recorded only from Java. 
Among the Asclepiadaceae there is an epiphyte, which is 
probably a new species of Pentanura, though the flowers are much 
larger than is usual in that genus. 
This specimen was procured by the expedient of shooting 
several charges of heavy shot into a mass of foliage, many feet 
above the ground, where the red glint of flowers could be dimly 
discerned. 
The Gesneriaceae are represented by a number of new species, 
belonging to the genera AEschynanthus , Didymocarpus, etc. 
Many of the species in this Order, especially in the section 
Gyrtandraceae, to which all the Old World species belong, have an 
extraordinarily limited distribution 1 , most (if not all) of the high 
mountain ranges of this region which have been yet explored 
botanically, having furnished their quota of new forms 2 . 
In the Order Acanthaceae there is a new species of Asystasia, 
and also a plant which will probably have to be put into a new 
genus, as it does not seem to fall at all naturally into any of those 
already recognised. 
Monocotyledons. 
The Orchidaceae furnish a new species of Dendrobium . This 
is a rather pretty epiphyte, with bright rose-purple flowers, which 
was found at a height of 5200 feet. It is closely allied to Dendro- 
bium cornutum, Hook. £, which is also a species from the Malay 
Peninsula. 
In the Gramineae is a curious bamboo, Bambusa Wrayi , Stapf. 
This bamboo, which grows in large clumps at a height of 4000 feet 
to nearly 6000 feet above sea level, is of interest partly on account 
of its rarity, being known only from two localities, both in Perak, 
i.e. Gunong Inas, and the mountains at the source of the Plus 
river 3 : but especially from the fact that it is the plant from which 
the Sakeis and Semangs, two wild non-malayan races of aborigines 
inhabiting the Malay Peninsula, make their ‘ sumpitans ’ or blow- 
guns. The stems of this extremely graceful bamboo are from 40 
to 60 feet high, and are remarkable for the extraordinary length 
of their internodes, which are often from 7 to 8 feet long, though 
they seldom reach a diameter of more than one inch. 
These long thin internodes the wild tribes use for their blow-
