NEW AND RARE MALAYAN PLANTS. - 1h: 
A robust form with large leaves 6 inches long and 2 inches . 
across, occurs on Gunong Mering, Mt. Ophir (3209). 
An elongate lanceolate narrow leaved form is from Gunong. 
Tungul, Dindings (7194), and a small compact form with rather | 
more coriaceous leaves was collected at Kwala Teku near Gunong * 
Tahan by Robinson (No. 5534). 
I think it probable that this is what Sir George King refers | 
to as Ophiorrhiza Mungos of the Peninsula. It is obviously different 
from the O. Mungos of Ceylon the type of the species. 
Ophiorrhiza singapurensis, n. sp. - 
Herb a foot’tall, litttle or not branched, stem succulent hairy 
glabrescent below. Leaves oblong lanceolate, acuminate obtuse, 
narrowed at the base hairy on both surfaces especially densely on 
the nerves beneath, light green above pale beneath, drying back 
brown above and red beneath, 5-6 inches long 1$-2 inches wide, 
petiole hairy 1 inch long. Stipules setaceous hairy. Cyme hairy 
peduncle half an inch long, branches as long. Flowers white, 
shortly pedicelled. Calyx short subcylindric shghtly dilate, lobes 
lanceolate. Corolla tube + nen long, lobes very short oblong all 
hairy outside. Fruit hairy 4+ inch across broadly V shaped, upper 
margin rather deeply indented, about half as long as wide.

Damar, Pulau Ubin (Hullett 424), Jurong 10763; Johore: Gu- 
nong Pulai (Ridley 12204), Gunong Panti (R. 4172), Sungei 
Tebrau (138221); Negri Sembilan: Bukit Sulu (Cantley); Din- 
dings: Lumut (Ridley 7195) ; Lingga Island (Hullett). 
This species appears to be confined almost entirely to the 
South of the Peninsula, and is abundant in Singapore and Johore, 
the only species in the island. It does not appear to have been 
col!ected by Wallich, nor it is taken up in the Materials. It is the - 
hairiest species of our region except O. tomentosa, Jack. 
Ophiorrhiza Kingiana, n. sp. 
Stem unbranched rather woody 6 to 15 inches tall, velvety 
hairy above. Leaves ovate to oblanceolate shortly acute at the tip 
narrowed at the base 2-inches long, one inch wide, nerves 8 pairs, 
above scabrid with minute raised dots, beneath very shortly velvety, 
of the same colour on both sides, margins fringed with hairs, 
petiole 4 inch long scabridly velvety. Peduncles axillary and ter- 
minal in flower } in fruit 1 inch long velvety, branches few short. 
Flowers small white £ inch long glabrous. Calyx minute cam- 
panulate with short points. Corolla tubular lobes short not re- 
flexed, white. Fruit 4 inch across, oblong rather deeply emarginate 
glabrous, somewhat resembling that of 0. erubescens, 
Perak: Dense jungle rock soil near limestone 300 to 500 feet, 
Gopeng, April 1884 (King’s collector 5853). 
Most nearly allied to O. tomentosa but much less hairy, and 
with fruit longer and narrower, and glabrous.
