NEW AND BAKE MALAYAN PLANTS. 75 



2.75-3 in. wide. Cyme axillary peduncle .1 stout. Flowers 

 numerous, crowded. Calyx cup-shaped, base blunt, edge trun- 

 cate, not lobed but minutely-irregular, pedicel stout nearly as 

 long .1 in. long. Petals white or pinkish, broad, ovate, blunt. 

 Style rather stout, short. Fruit black, globose .2 in. through. 



M. ample.vicaule, King and others not of Roxburgh. 



Pexaxg; (Wallich 4101C.) Experimental Nursery; 

 (Curtis 965 and 457); Moniot's Road (Ridley). Pekak; 

 (Scortechini 231) ; Larut, 800-1,000 ft. (Kunstler, M. hetero- 

 pleurum var. olivaceum, King! and 3058 Kunstler), Waterloo 

 (Curtis 1294). 



The Penang plants have long, narrow lanceolate leaves, 

 while those of Perak have shorter, broader, ovate ones, but 

 there are intermediate forms. Generally speaking the plant 

 resembles M. hetevopleurum, Miq. but that has the leaves very 

 shortly cuneate, never rounded or cordate and the flowers about 

 half as big. 



M. costatum, Miq. Verh. Xed. Inst. 1850, p.. 29 is record- 

 ed by King from Perak (Kunstler 10785) ; I have not seen this 

 specimen and there is no specimen of Miquer's species from the 

 Peninsula at Kew. King's description differs from Miquer's 

 in " base of leaves rounded or slightly narrowed, not cordate " 

 whereas MiqueFs species had cordate leaves, and in " flowers 

 in axillary glomeruli " instead of widely spreading panicled 

 cymes. So it seems clear that King's M. costatum is not 

 Miquer's. 



RUBIACEAE. 



Uncaria parviflora, n. sp. 



Uncaria lanosa var. parviflora, Ridl. Journ. Roy. As. Soc. 

 Str. Br. lix, p. 109. 



Climber with 4 angled stems, .2 in. through, sparsely 

 hairy, branches more densely hairy with short rough hairs. 

 Leaves lanceolate, acuminate, base broad, membranous, scabrid 

 hairy above, beneath velvety hairy; nerves about 7 pairs^ 

 slender elevate beneath, 2.75 in. long, 1.25 in. wide; petiole 

 .1 in. Stipules linear acuminate, bifid, hairy .1 is. long. 

 Peduncles rather slender narrowed upwards, sparsely hairy 1 

 in. long. Peduncles rather slender, narrowed upwards, sparse- 

 ly hairy 1. in. long. Heads globose .5 in. through. Calyx 

 sessile, silky, obconic, very small with short oblong obtuse lobes 

 about half the length, glabrous within. Corolla sparsely silky, 

 hairy; tube very slender .2 in. lobes oblong ovate blunt,, 

 glabrous within. 



Perlis, Chupeng in open countrv, forming large bushes 

 (Ridley 15019). 



On further examination I find that this plant is specifical- 

 ly distinct from U. lanosa.
