Styrax conterminum.— Indument leprous, nowhere stel- 
late, scales lacerate, ferruginous on branchlets petioles and 
calyx: leaves elliptical-oblong (5-6x 1}-2"), conterminously 
acuminate, long-petiolate (9-11'), coriaceous, scales of upper

with red: racemes chiefly simple, twice exceeding petioles; 
flowers large (7'), pedicels as long and minutely bracteo- 
late at base and middle: corolla silvery, thrice exceeding the 
minutely toothed calyx: filaments half-connate, twice longer 
than the short (2') and oblong anthers, exbarbate within, 
their exterior beset with fimbriate scales.—The other three 
species of the lepidote group, all South American, can be

‘lanceolate (838 Rusby Fl. S. Am.! 467 Bang Pl. Beliv.!): in 
S. cordatum A. DC. cordate-ovate: in S. /eprosum Hook. et

leaves, corymbose, densely flowered, slightly pubescent: 
flowers among the smallest of the genus (3'): calyx a third 
as long, campanulate, broadly and obtusely lobed to middle: 
lobes of corolla exceeding tube, oblong, revolute.— Habit
