to the base, thin in texture, green and pilose on both surfaces. 
Flowers solitary and in short spikes from the axils of the leaves 
all down the branches, nearly sessile, each subtended by a pair 
of lanceolate foliaceous bracteoles adpressed to the calyx. Flower- 
calyx 4-3 in. long, pilose, cut down to the base into 5 equal 
linear segments. Corolla purple, with a curved tube an inch 
long, 3-3 in. in diam. at the throat, and 5 semiorbieular segments 
iin. long and broad. Anthers 4, oblong, muticous; filaments 
inserted about the middle of the corolla-tube; longer 4 in., 
shorter jin. long. Style AE ed de the stamens, with 2 unequal

of the province of Imerina, Parker! Baron 1075! Forest of

spicato-paniculatis, bracteis minutis lanceolatis, calycis tubo brevissimo

An erect perennial herb or undershrub, glabrous in all its 
parts, with very slender tetragonous branches. Leaves distant, 
opposite, conspicuously petioled, 13-2 in. long, acute, rounded 
at the base, thin in texture, green and glabrous on both surfaces. 
Flowers in short rather lax peduncled spikes from the axils of 
the upper leaves; bracts lanceolate, acute, glabrous, shorter than 
the calyx. Calyx 4; in. long, glabrous, with a very short tube 
and 5 lanceolate acute teeth. Corolla iin. long, with a pilose 
cylindrical tube and a bilabiate lip not more than 4L in. long. 
Stamens 2, inserted about the middle of the corolla-tube, with 
filiform filaments 4^; in. long and two oblong muticous cells, one 
much higher than the other. Stigma bifid, exserted from the 
corolla-tube— Central Madagascar, Baron 1216! Only differs 
from Justicia by its stamens. Mr. C. B. Clarke has kindly helped 
me in the determination of this and the other Acanthacew of the 
collection.
