1. S. rufescens, T. Anders, in Journ. Linn. Soc.ix.472; leaves ovate

 bracts broadly ovate, calyx 2-partite both segments very shortly toothed.

PEGU ; Brandts. DISTRIB. Moluccas (Roxburgh). 



A shrub ; branches perfectly glabrous, or intensely shaggy with red hairs |-j in. 

 long. Leaves 1^4 in., often unequal, base obtuse or rounded, hirsute on both surfaces 

 in the type examples, nerves 6 pair; petiole -! i Q - Spikes 1-2 in., short- 

 peduncled ; bracts ^ in., fulvous-hirsute ; bracteoles scarcely in., sublinear. Calyx 

 ^ in., 2-partite to the base, rufous-ciliate towards the apex ; segments very shortly 

 toothed, one 2-toothed, the other 3 -toothed with the middle tooth broader subemargi- 

 nate. Corolla 1 in., pale-purple, cylindric base of the tube rather shorter than the 

 moderately ventricose part. Capsule ^ in., densely pubescent, 4-seeded. Seeds less 

 than T 'j in., orbicular, fine elastically white-hairy, areoles 0. 



VAE. rubiginosa ; leaves larger thinner glabrate lineolate above, bracteoles -^ in., 

 ovate. Tenasserim; Heifer (Kew Distrib. n. 6118^. Chittagong; Clarice. Stems 

 thinly shortly rufous-hirsute ; leaves 5 by 2| in., base shortly acuminate, crenate, 

 green, herbaceous ; nerves beneath thinly rufous-hairy. Heifer' s^-exam pie is unlike 

 those of Euellia ulmifolia, but very like the figure of .5. comosa, Roxb. Clarke's 

 examples have the stems sparsely or densely rufous-hirsute, the leaves glabrate lineolate 

 above or rufous-hirsute; the corolla is 1| in., pale-purple, nearly glabrous with 

 glabrous filaments, altogether as in Roxburgh's picture. 



2. S. acuminatus, T. Anders, in Journ. Linn. Soc. ix. 473, partly ; 

 leaves lanceolate acuminate at both ends crenate nearly glabrous, spikes 

 oblong short-peduncled glandular, bracts ovate shorter than the calyx, 

 calyx sub-2-partite one lip shortly trifid the other bifid nearly to the base.
