middle of the tube, in the ample and compressed faux, and 
especially in the large boat-shaped lower lip. ‘The style, too, 
is bent at an angle in conformity with the tube of the corolla. 
The species seems to be confined to the island of Ceylon. Mr. 
Bentham notices its affinity with C. Malabaricus, “a quo differt 
foliis multo minoribus angustioribus et inflorescentia.” 
Descr. Nearly glabrous in every part. Stems two to three 
feet high, quadrangular, dark purple, branched, with opposite

inches long, with petioles four to five inches long; upper ones 
gradually smaller and on shorter petioles; all of them ovate, 
acuminate, serrated, submembranaceous, somewhat glossy, dark- 
green above, beneath deeply purple, as are the petioles ; the veins 
pinnated, with the lateral ones united by cross veinlets. Panicle

broad ovate, mucronated. Pedicels very short. Calya small, 
cup-shaped: upper lip of one large cordate acuminated tooth ; 
lower hp quadridentate, spreading. Corolla large, white: the 
tube long, slender, below gibbous on one side at the base, sud- 
denly geniculated or bent at an angle near the middle; the faua 
very large, compressed: upper dip erect, broad, truncated, two- 
lobed, with a large purple blotch, each lobe emarginated ; lower 
lip very large, boat-shaped, acute. Stamens lodged in the lower 
lip, and not protruded beyond it. Anthers short, oblong, apicu-
