NEW AND BABE MALAYAN PLANTS. 19 



Native name " Akar Surukop." 



This plant appears to me to be quite distinct from the 

 Hongkong plant, the flowers of which are larger and in um- 

 bellate cymes on the ends of branches, not as in this case in 

 racemes of small cymes. The petals are smaller and narrower, 

 and the fruit smaller, the valves being as long as they are 

 wide. 



Microtropis valida, n. sp. 



Branches stout. Leaves thickly coriaceous, shining, ellip- 

 tic, acuminate acute, base cuneate, 3.5 to 6 in. long, 1.5 to 3 

 in. wide, nerves 6 to 8 pairs, slender, nervules and reticulations 

 equally prominent on both sides, petiole thick grooved .5 in. 

 long. Cymes stout, 3 in. long, peduncle 1.5 in. long, branches 

 .5 in., branch-lets .2 in. long. Flowers clustered in threes on 

 the end of each branchlet, .4 in. across, sessile. Sepals 4, 

 imbricate, rounded in two unequal pairs, glabrous, coriaceous 

 with thinner edges, the inner pair the largest. Petals connate 

 below, lobes 4, short, broad, rounded. Stamens 4 inserted on 

 the tube, filaments broad. Pistillode truncate. 



Peeak. Hermitage Hill (Curtis 1331). 



Euonymus rufulus, n. sp. 



Small tree with grey rather knotted branches. Leaves 

 opposite, coriaceous, glabrous, elliptic, blunt, acuminate at 

 both ends, base subacute, nerves about 5 pairs, invisible above, 

 obscure beneath, midrib elevate on both sides, 1.5 — 4 in. long, 

 .5 — .75 in. wide; petiole .25 in. long, thick, grooved. Cymes 

 several in an axil, slender, peduncle .4 in. long, pedicels as long, 

 about 3. Flowers dull red, .15 in. across. Sepals orbicular 5. 

 Petals transversely rounded, oblong, minutely denticulate punc- 

 tate. Stamens 5, very short, filaments subtriangular, flat; an- 

 thers transversely oblong; style short. 



Pahang. Gunong Tahaii at 5000 ft. alt. (Robinson and 

 Wray 5332). Small tree, flowers dull red. 



A very distinct species with more coriaceous leaves, and 

 smaller flowers with shorter, broader petals than E. IXrayi 

 which is probably its nearest ally. 



Salacia rubra, Lawson in Hook, fil., Flora of British India, I. 627. 



Of this dubious plant collected formerly by Maingay, who 

 had only fruiting specimens, we have now adequate material, 

 collected in the garden jungle in Singapore by me, (No. 10164 

 of my collections), so I give a complete description of it. — A 

 climbing shrub with whitish bark. Leaves opposite, elliptic 

 cuspidate, narrowed to the base entire, coriaceous and drying 

 dark brown, nerves 5 to 6 pairs, faint inarching far from the
