NEW AND RARE MALAYAN PLANTS. 37 



Capsule 1.1 in. across, .5 in. long; lateral wings blunt, trian- 

 gular; posterior .75 in. long, .3 in. wide, oblong rounded, 

 thick ribbed. 



Selangor. Ulu Gombak, on rocks in the stream (Rid- 

 ley). 



This belongs to the jungle stream set of Begonias with 

 narrow lanceolate leaves hardly or not lobed or unequal at 

 the base, viz. B. Kunsileriana (B. Scoriechinii) and B. perak- 

 ensis, King. The latter has the leaves rounded. The former 

 has them narrowed but not decurrent on the petiole as in 

 rhoephila and very hairy. I take B. Scoriechinii, King, of 

 unknown locality to be a narrow leaved form of B. Kunstler* 

 iana. 



ARALIACEAE. 



Schefflera, Forst. This genus was made by Forster for two 

 species of plants, one from New Zealand and the other from 

 Fiji. Later the genus H eptapleurum was founded by Gaert- 

 ner, to which a considerable number of Asiatic species were 

 attributed. The difference between the two genera is how- 

 ever, too slight to warrant their being kept distinct and Harms 

 in the Pflanzenfamilien has placed the Heptapleurums under 

 the earlier name Scliefflera, in which I follow him, excluding 

 however, the genus Brassaia which appears to me sufficiently 

 distinct. It may however, be found necessary to separate from 

 Schefflera such abnormal plants as 8. (II.) Wrayi, with race- 

 mose not umbellate flowers; and I am rather dubious of the 

 following new species which has the number of stamens double 

 that of the perianth lobes and ovary cells. 



Schefflera polyandra, n. sp. 



Leaves digitate ; petiole 9 in. long ; leaflets 5, oblanceolate 

 or oblong lanceolate acuminate, blunt, base narrowed, edge 

 serrate, coriaceous, glabrous, smooth, nerves 7 pairs faint, 

 reticulations faintly visible beneath, 4 — 6 in. long, 1.25 to 1.75 

 in. wide, petiolule 1.3 in. long. Panicle 5 in. long, branchlets 

 .5 in. long, umbels of 4 — 5 flowers; pedicels .2 in. long, stout. 

 Calyx campanulate, edge thin, truncate, entire .1 in. long. 

 Petals shorter, ovate, 5. /Stamens 14 to 16; anther as long 

 as filament. Style conic, cylindric. Ovary 8-celled. 



Perak. Gunong Keledang (Ridley 9763). 



Arthrophyllum pinnatum, Clarke. LTnder this name in King's 

 Materials two plants have been combined, one the true A. 

 pinnatum of the Penang Hills. The other a smaller plant 

 with many more smaller leaflets and smaller flowers, A. alter- 

 nifolium Maingay, MS. a native of Mt, Ophir,
