122f Materials for a Flora of the Malayan Peninsula} 



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

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

 Female Jlowei's like the jnfi] en, 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, reflex ed lobes, each bearing a stigmatic 

 surface internally; 1-celled with 4 raulti-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, copiouSj 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 heterophyllus 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. Bat the following have been discovered by 

 Messrs. Kunstler and Wray in Perak. And, fiom the similarity in 

 externals to Hydnocarpus, and from the imperfect nature of tlie Herba- 

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

 several things now referred to Hydnocarpus really belong to Tarakto- 

 genos. In the Calcutta Herbarium, there are imperfect materials 

 of, at least, 8 undesci'ibed species which belong either to one or other of 

 these two genera. 



3. 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 

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

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

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

 8"5 to 7 in., breadth 15 to 275 in.; petiole "5 to 75 in. , Cymes tricho- 

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

 few-branched, uniparous. Male flowers '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 flowers and fruit unknown.

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

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