6. Dysoxtlum venulosum, Kiiig, n. sp. A tree 50 to 80 feet high ; 

 young branches rather stoat, angled, puberulous. Leaves 12 to 18 in. 

 long, the petiole and rachis angled and puberulous, equally or unequally 

 pinnate; leaflets 7 to 14, membi-anous, alternate, oblong, slightly un- 

 equal^sided, acuminate, the base mucli narrowed and oblique ; both sur- 

 faces glabrous, the 13 to 15 paii'S of oblique curving main nerves indis- 

 tinct on the upper, rather prominent on the lower, the veins on both 

 surfaces prominent and winged when dry ; length 5 to 7 in., breadth 

 1"35 to 1'75 in., petiolules 25 in. Panicles extra-axillary, 6 to 8 in. 

 long, glabi'escent ; the bi'anches numerous, short, sub-liorizontal, few- 

 flowered. Flowers 25 in. loug ; their pedicels about the same length, 

 jointed at the middle. Calyx cupular, with 4 shallow teeth, glabrous. 

 Petals 4, much longer than the calyx, densely hairy, puberulous extcrr- 

 nally, sparsely so internally, oblong, obtuse, the apex slightly thickened 

 and inflexed. Staminal tube slightly shorter than the petals, glabrous, 

 cylindric, its mouth irregularly and minutely toothed ; anthers 8, oblong, 

 inserted below the mouth of the tube. Disc cylindric, fleshy, glabrous, 

 about as long as the ovary, the mouth with 4 broad minutely erose

7. Dysoxylum thyrsoideum. Griff, ex Hook. fil. Fl Br. Ind. I., 547* 

 A tree ; leaves 12 to 16 in, long, their petioles and racbises angled: 

 leaflets about 8, alternate, coriaceous, elliptic-oblong to elliptic, shortly 

 acaminate, slightly nan-owed to the oblique base, both surfaces quite 

 glabrous ; main nerves 6 to 8 pairs, curved, ascending, slightly depressed 

 in the upper and prominent on the lower surface when dry ; length 

 4"5 to 8'5 in., breadth 1"75 to 3 in., petiolules "3 in. Panicles slightly 

 extra-axillai-y, pyramidal, with stout racbises less than half the length 

 of the leaves ; their main branches divaricating, the ultimate racemose 5 

 flowers numerous, 15 in. long, their pedicels nearly as long. Gulyx one- 

 third of the length of the petals, cupular, coarsely and irregularly 

 4-toothed, glabrous. Petals 4, oblong, obtuse, glabrous. Staviinal tube 

 shorter than the petals and attached to them, cylindric, glabrous outside, 

 pubesceut inside, its mouth with 8 broad sub-crenate teeth ; anthers 

 short, ovate, included. Disc tubular, fleshy, hairy, slightly exceeding 

 the ovary, truncate. Ovary narrowly ovoid, sub-strigose, 3-celled ; 

 Btyle cylindric, thick, as long as the stamiual tube ; stigma exserted, 

 discoid with a basal ring. Fruit (fide Hieru) " obovoid, fleshy, 2- 3-
