4. DiosPTEOs DUMOSA, King & Gamble, n. sp. A small tree ; 

 young branches as thick as a crow-quill, glabrous, dark-coloured 

 when dry. Leaves small, alternate, membranous ; lanceolate, shortly 

 acuminate, the base cuneate ; upper surface dark olivaceous when dry, 

 glabrous ; lower yellowish, slightly puberulous on the slightly pro- 

 minent midrib and 4 or 5 pairs of curved ascending nerves ; length 1-5 

 to 2 in. ; breadth -5 to "75 in. ; petiole -05 in. Male flotvers -5 in. long, 

 in small axillary sessile fascicles of 3 or 4. Calyx -25 in. long, deeply 

 divided into 3 or 4 ovate-lanceolate acuminate lobes, concave along the 

 midrib, and with undulate edges, pubescent. Corolla twice as long as the 

 calyx, narrowly tubular, deeply divided into 4 narrow oblong glabrous 

 lobes, the tube pubescent inside and outside. Stamens 12, inserted at 

 its base on unequal slender filaments ; anthers broadly lanceolate, 

 much apiculate. Female floiuers solitary, axillary, shortly pedicellate, 

 •4 in. long. Calyx cleft to the base into 4 large broadly ovate reniform 

 bluntly acuminate undulate lobes, sparsely adpressed-pubescent on 

 both surfaces, •25 in. long and as much across. Corolla a Httle 

 longer but less hairy than the calyx, fleshy, tubular, tetragonous, 

 divided for half its length into 4 narrow oblong lobes. Staminodes 

 8, linear-lanceolate, apiculate, on slender filaments. Ovary narrowly 

 ellipsoid, tapering to the rather long style, glabrous. Fruit unknown.

5. DiosPYEOS GEACiLiFLOEA, Hiem in Trans. Camb. Phil. Soc. 

 XII. 191 (1873). A glabrous tree 40 to 50 feet high; young branches 

 less than half as thick as a goose-quill, deciduously puberulous, dark- 

 coloured and striate when dry. Leaves thickly membranous, alternate ; 

 rather narrowly elHptic, shortly and bluntly apiculate to caudate- 

 acuminate, the base much narrowed and often sHghtly obhque ; both 

 surfaces dull dark olivaceous -brown when dry, glabrous except for 

 some minute hairs on the nerves beneath ; main-nerves about 5 pairs, 

 curved, ascending, depressed or obscure on the upper surface, pale and 

 slightly prominent on the lower like the midrib ; length 2-5 to 4-5 in., 

 breadth -75 to 1-35 ; petioles -1 to -2 in. Male floioers -5 in. long, few 

 together, in small axillary cymes about as long as the petioles, sessile, 

 puberulous. .Calyx large, two-thirds to one-half the length of the 

 corolla, but much wider, deeply divided into 4 large ovate-rotund 

 undulate semi-erect lobes. Corolla narrowly tubular, one-third to one- 

 half longer than the calyx ; the tube externally with 4 lines of 

 pubescence, otherwise glabrescent; limb with 4 deeply oblong broad 

 blunt glabrous spreading sub-undulate lobes. Stamens 8, in two rows.
