122 G. King — Materials for a Flora of the Malayan Peninsula. [No. 2, 



cuneate, plano-convex, ridged, the apex often irregularly toothed and 

 with 2 or 3 cylindric pits. Stamens 20 to 32, the anthers deeply cordate. 

 Female flowers like the males, but the sepals often only 3, the petals 

 6, and the stamens 16 or 17 ; ovary elongate-ovoid, sulcate, divided 

 above into 4 oblong, divergent, reflexed lobes, each bearing a stigmatic 

 surface internally; 1-celled with 4 multi-ovulate parietal placentas. 

 Fruit large, globular or ovoid, with hard fibrous or woody rind, and 

 several large seeds embedded in a scanty pulp. Seeds with thick hard 

 testa, copious albumen, and straight central embryo ; the cotyledons 

 large, cordate, foliaceous, 3-nerved. Species probably about 8 : all 

 Malayan. 



Note. — This genus was founded by Hasskarl (Retzia, i. 127) on the 

 plant named Hydnocarpus heterojjliylJus by Blume (Rumphia, iv, 22, t. 

 178 B., fig. 1, and Mus. Bot. i, 16). Until now that plant has been 

 the only known species. But the following have been discovered by 

 Messrs. Kunstler and Wray in Perak. And from the similarity in 

 externals to Sydnocarpus, and from the imperfect nature of the Herba- 

 rium materials of the latter, it appears to me extremely probable that 

 several things now referred to Hydnocarpus really belong to Tarakto- 

 genos. In the Calcutta Herbarium, there ai'e imperfect materials of 

 of, at least, 8 undescribed species which belong either to one or other of 

 these two genera. 



1. Taraktogenos Scortechinii, King, n. sp. A large glabrous 

 tree ; young branches with dark-coloured bark. Leaves coriaceous, shining, 

 inequilateral, oblong-lanceolate, oblong or elliptic, with a short abrupt ra- 

 ther blunt acumen and slightly waved edges ; the base slightly narrowed 

 and unequal, 3-nerved, ; the upper surface smooth, the lower rough from 

 the prominent reticulations and 4 to 5 pairs of ascending nerves ; length 

 3'5 to 7 in., breadth 1*5 to 2'75 in. ; petiole '5 to '75 in. Cymes tricho- 

 tomous, 1 in. in diam., on pedicels as long as the petioles, solitary, axillary, 

 few-branched, uniparous. Male floiuers "5 to - 6 in. in diam. ; pedicels "25 

 to '35 in. Petals densely sericeous externally ; the basal scales less than 

 half their length. Stamens 20 to 24, filaments hirsute, anthers sagittate. 

 Female floiuers and fruit unknown. 



Perak; Scortechini, No. 833; Wray, 1169. 



Var. gracilipes, King; petioles longer ('75 to 1 in.) and more slen- 

 der; leaves smaller, 2'5 to 4 in. long, by P25 to 1*5 in. broad. 

 Perak ; Bujong-Malacca ; Scortechini, No. 1894. 

 2. Taraktogenos Kunstlert, King, n. sp. A sub-glabrous tree 40 to 

 60 feet high. Toting branches fulvous-pubernlous. Leaves coriaceous, un- 

 equal-sided, oblong-lanceolate to ellijjtic, shortly acuminate ; the base nar- 

 rowed and unequal, 3-nerved ; both surfaces shining, the lower rough from
