394. MR. H. N. RIDLEY ON THE FLORA OF THE 
COLOCASIA ANTIQUORUM, Schott. 
Commonly cultivated. It occurred as an escape from cultivation or accidentally 
planted in the Tahan valley woods, far from the mouth. 
ALOCASIA LONGILOBA, Miq. 
This appears to be the name of the common wild Alocasia so abundant in the Singapore 
woods. Тһе foliage is very variable in shape, and in seedlings is peltate, and not bilobed 
at all like those of A. perakensis, Hemsl. I do not understand exactly the difference 
between A. longiloba and A. denudata, Engl., which is said to be a Singapore plant, but 
I know only one species as а wild plant here. 4. longiloba, Miq., is plentiful at Pekan, 
but becomes scarcer further in the province. I met with it, however, far up the Tahan 
River.

CHAMACLADON GRIFFITHII, Miq. 
Common, Tahan woods. 
There is a very pretty silvery-leafed form of this plant which is not rare іп damp 
forests. I have seen it in Malacca and Selangor, and it was plentiful in the Tahan 
woods. At first sight it looks very different from the common green-leafed form, but I 
can find no constant specific difference. The leaves are very variable, as indeed in most 
Aroids. The petiole is stout, slender, sheathed for from less to half to two-thirds of 
its length ; the base of the leaf-blade is usually rounded and the broadest part, or it may 
be quite acute. The silvery-leafed form may be characterized as var. argentea. | 
Leaves silvery above, pale beneath, with red veins; petioles red; spathes red. 
There are two other species of Chamecladon in the collection—one, perhaps C. saxorum, 
Miq., from Kota Glanggi, and the other from the Tahan woods. | 
SCHISMATOGLOTTIS, spp. 
Several species were met with in Pahang, and I have others from Singapore and else- 
where which I cannot identify with any described species. Тһеу have, however, 
probably been described among the Aroids of the ‘Flora of British India, the part 
containing which has not yet reached me. |
