New and Rare Malayan Plants, 

 Series VIII. 



By H. X. BlDLEY, F.K.S. 



Herewith I give an account of some additions to the Flora of 

 the Malay Peninsula, with notes on species insufficiently or in- 

 correctly described, in continuation of the Series previously des- 

 cribed in the Journal. 



Ryparosa Wallichii, n. sp. (Bixacece). A tree; branches when 

 young covered with red hair. Leaves glabrous above, cori- 

 aceous, lanceolate-oblong, base slightly narrowed, apex acute, 

 pale whitish beneath, 8-9 inches long, 2 inches wide, the nerves 

 five pairs, elevated, ascending, often hairy beneath; midrib 

 also hairy; petiole 1.5 inches long, hairy. Male racemes axil- 

 lary or from the trunk of the tree, 6-8 inches long ; bracts 

 small, lanceolate; pedicels -25 inches long. Flowers *2 inches 

 long, yellow. Sepals 5, short, ovate, hairy. Petals rounded, 

 hairy, much larger than the sepals, with the scale inside about 

 half as long, and hairy. Staminal column glabrous : anthers 

 4, oblong. 



Singapore: Gardens' jungle (Ridley). Pexang: "A 

 climber from the hills, October" (Wallich 7847B) ; Herb. 

 Finlayson (Wallich 7847A). 



Wallich's specimens are like the Botanic Gardens ones — 

 male, but with young spikes, axillary and quite short. Those 

 from the Gardens' jungle were fully developed and borne on 

 the trunk. Wallich describes it as a climber from the Penang 

 hills ; but it has not been collected again, and as no species of 

 the genus is a climber, it is possible that the label is wrongly 

 affixed. The species is chiefly remarkable for its narrow leaves 

 and hairy inflorescence. 



Xanthophyllum puberulum, n. sp. (Polygalacece). A large 

 shrub with pubescent branches. Leaves oblong-elliptic or lan- 

 ceolate, cuspidate, shortly narrowed at the base, thinly cori- 

 aceous, 5*5 to 8 inches long, 2*25 to 2*75 inches broad, nerves 

 5 to 6 pairs, elevate beneath ; reticulations large, all pubescent : 

 petiole -25 inches long. Flowers white, in short terminal 

 panicles 2 to 3 inches long, pubescent: branches few. Sepals 

 unequal, ovate obtuse, minutely pubescent. Petals spathulate, 

 glabrous : keel slightly pubescent. Stamens glabrous except at 

 the base. Ovary villous, stipitate; ovules 4. 



Selaxgor: by the stream at Klang Gates (Ridley 13396). 

 Dixdixgs: at Lumut (Ridley 10366). Flowering in August.
