roots along the internodes, and in its calyptrate calyx, it is very 
similar to Korthals’s species. The floral characters of the present 
have been worked out from nearly mature buds; they may be 
subject to slight modifications when open flowers are available.

| A scandent shrub, the branchlets, petioles, inflorescences, and. 
the lower surface of the leaves rather densely ferruginous-stellate- 
pubescent. Leaves opposite, elliptic to elliptic-ovate, chartaceous, 
9 to 12 em. long, 4.5 to 6 em. wide, the upper surface greenish, 
shining, glabrous or nearly so except the somewhat pubescent 
midrib, the lower surface ferruginous or brownish and conspicuously 
pubescent with scattered stellate hairs, base usually rounded, not 
at all cordate, 5-nerved, the marginal nerves more slender than 
the inner pair, the apex distinctly acuminate; transverse nervules 
prominent on the lower surface; petioles densely stellate-pubescent, 
1 to 2 em. long. Inflorescences axillary and terminal, peduneled, 
cymose, the axillary ones up to 7 cm. long, the terminal ones 10 
cm. long, sometimes supplied with greatly reduced leaves, the bracts 
Jinear-lanceolate, about 3 mm. long, the peduncies, pedicels, and 
calyces very densely stellate-pubescent with ferruginous or brown- 
ish hairs. Calyx about 1.5 cm. long, base cuneate, the throat about 
1 cm. in diameter and with 4, very short, broad, rounded lobes. 
Petals white, glabrous, elliptic-obovate, rounded, about 2 cm. long, — 
1.2 em. wide, more or less narrowed to the subacute base. Stamens 
8, their filaments about 1.6 cm. long, the 4 longer anthers 2.5 cm. 
long, rostrate, much narrowed at both ends, the connectives not 
produced, the anterior appendages setiform, about 9 mm. long; 
shorter anthers sigmoid, the apical rostrate part recurved, the 
anterior appendages similar to those of the longer stamens. 
British North Borneo, Sebuga, near Sandakan, Ramos 1758, 
December, 1920. In open forests at low altitudes. A species most 
closely allied to Dissochaeta punctulata Hook. f., from which it 
differs especially in its much larger flowers and longer petioles and 
anthers.
