s'Kellat. The latter epithet is however also applied in Malacca to a form of the 

 very different species D. platy sepal um. No native name is cited with the Perak 

 specimens or with the Singapore ones. 



6. DiALiUM AMBiGUUM Prain. A tree 40-50 feet liigli, stem 5-8 

 in. in cliam. ; branchlets very verrucosely lenticelled, glabrous, blackish. 

 Leaves alternate, odd-pinnate, 8-9 in. long; leaflets 7, opposite or rarely 

 subopposite, oblong, rather abruptly shortly caudate-acnminate apex 

 obtuse entire, b;ise rounded, 4-5 in. long 1'5-1"75 in. wide, very rigidly 

 coriaceous, bright-green, glossy and glabrous above, dull and faintly 

 puberulous under the lens beneath ; leaf-racliis glabrous ; lateral nerves 

 9-11 pairs, fine, only visible beneath, foi'ming distinct intra-marginal 

 loops and with a fine intermediate reticulate secondary venation ; 

 pefciolules glabrous "2 in. long. Panicles terminal and axillary, deltoid, 

 slightly spreading, 5-8 in. long, 4-8 in. wide, branches 2-4 in. long very 

 sparsely puberulous with grey-.=silky hairs as is the main vachis ; pedicels 

 usually in clusters of 3, "15 in. long, Oahjx "15 in, long, ovoid in bud, 

 tube obsolete, segments 5, subequal, much imbricate, broadly triangular 

 subacute, reflexed after flower opens; densely brown-velvefey on both 

 surfaces. Petals 0. Stamens 2, opposite ti»e two upper calyx-segments ; 

 filaments thick and fleshy one-third as long as anther. Ovary light 

 green-silky, ovate, quite sessile, tapering gradually into the glabrous 

 style ; ovules 2. Pod and seed unknown,

This tree is evidently very closely allied to D. platysepalum and may ultimately 

 prove to be but a form of that vai-iable species ; if so, however, it is an exceedingly 

 distinct variety, readily i-ecognised owing to the differences in its ovary, in its 

 pubescence, and in tlie ai-r;ingement of its leaflets. No native name is given for 

 the Perak specimens ^ those from Malacca that appear to belong ta the same 

 species arc simply termed Kranji. 



7. DiALiUM PLATYSEPALUM Bak. in Flor. Brit. Ind. II, 270. A 

 tree 40-50 feet high; branchlets brown, closely-puberulous, sparsely 

 lenticelled. Leaves alternal:e, odd-pinnate, 5-9 in, long; leaflets 5-7, 

 usually conspicuously alternate, or rarely subopposite, elliptic or oblong 

 to ovate-lanceolate, rather abruptly shortly caudate-acuminate apex 

 obtuse entire, base rounded or cuneate, 3-5 in. long, 1-2 in. wide, very 

 rigidly coriaceous, dark-green glossy and glabrous above, densely shortly 

 yellowish -brown silky beneath ; leaf-rachis finely puberulous ; lateral 

 nerves 9-11 pairs, fine, only visible beneath, forming distinct intra- 

 marginal loops and with a fine intermediate secondary reticulate 

 venation ; petiolules puberulous *25 in. long. Panicles terminal and 

 axillary, deltoid, close or slightly spreading, 5-8 in. long, 4-7 in. wide, 

 brandies 2-3 in, long, erecto-patcnt, finely brown-silky as is the main-
