floriferous at the apex, with a broad villous line on one side. Flow- 

 ers secund, 20-25, blue. Pedicels villous on one side, about 2 

 lines long, each with a small subulate bract at its base. Calyx 

 free, persistent, green, about 3 lines long. Tube 5 -angled, the 

 upper angle with a deep rounded wing-like crest on its lower half, 

 the others very slightly and equally winged, glabrous except the 

 angles which are pilose. Limb 5 -cleft, lobes equal, erect, ovate, acute, 

 with a glandular tip, margins ciliated. Corolla hypogynous, gamo- 

 petalous : tube cylindrical, white, about 5 lines long, with the throat 

 closed, glabrous. Limb bilabiate, upper lip ovate, dentately truncate, 

 reflexed, about 3 lines long, deep blue, lower lip large, broadly ellip- 

 tical, obtuse, entire, about 15 lines long, by 11 lines broad, with two 

 oblong concavities at the base, of a deep blue colour, but with a yel- 

 low blotch at the base. Stamens 4, didynamous : filaments filiform, 

 reaching to the base of the upper lip of the corolla. Anthers all per- 

 fect, 2- celled, glabrous, cohering in a mass. Hypogynous gland entire, 

 cup- shaped, about 1 line deep, and of a whitish colour. Ovary free, 

 ovate, glabrous, 1- celled, with two parietal placentae, each with 2 

 divaricate straight ovuliferous laminae. Style filiform, glabrous, per- 

 sistent. Stigma capitately cup-shaped. Capsule enclosed within 

 the calyx, somewhat obovate, 1 -celled, 2-valved, with a loculicidal 

 dehiscence, the valves bearing the placentae along their middle. 

 Seeds numerous, oblong, pendulous : testa brown, reticulated. 



Obser. I. — As no detailed description of this species has 

 hitherto been published, I have thought it proper to give 

 one here, in order that it may be contrasted with the other 

 two Ceylon species, from both of which it may readily be 

 distinguished by the broad villous line which runs along the 

 upper part of the stem, the racemes, and the pedicels. My 

 Ceylon specimens agree in every respect with those which 

 I collected on the Neilgherries, along with Dr. Wight, in 

 February 1845. The character which M. Alphonse De 

 Candolle gives of the calyx is a most erroneous one, viz. 

 " Calyce basi superne grosse et obtuse calcarato." What 

 he has taken for a spur is the winged expansion of the 

 lower part of the upper angle. He further states, that the
