Thwaites from the hilly country of Ceylon.' An error is certain, as this

Annual, stems erect, i-il- ft., much branched, glabrous, 

 flaccid ; 1. opposite (sometimes 3 or 4 in a whorl), nearly 

 sessile, 1-3 in., linear or lanceolate-linear, acute at both ends, 

 distantly spinous-serrate, glabrous, stip. small, acute ; fl. about 

 ^ in., usually solitary (rarely 2 or 3), axillary, on very slender, 

 glabrous ped. ; sep. very small, oval, acute, lip boat-shaped, 

 with a very short, stout, curved spur ; standard rotundate, 

 notched ; wings approximated, lower lobe much the larger, 

 oval, obtuse, upper falcate, acute ; capsule under i in., fusi- 

 form ; seeds glabrous, black. 



Wet places in all parts of Ceylon ; very common. Fl. all the year ; 

 pink. 



Also in S. India. 



The only one of our species o{ b)ipatie7is which extends into the dry 

 region. 



/. tenella., Heyne. Specimens from Nilavelli, near Trincomalie, sent 

 by Mr. Ferguson in 1885, are probably this species. The upper leaves 

 are very nari'ow, almost filiform, and often in whorls of 3, the sep. linear 

 acuminate ; the spur is longer than in ordinary /. oppositifolia^ and the 

 whole plant much more slender and delicate.

Perennial ; stem stout, 6-8 ft., somewhat woody below, 

 slightly branched, glabrous, branches usually nodulose with

 especially into petiole, closely spinous-serrate with the lower 

 teeth filiform, glabrous, paler beneath, with the lat. veins ob- 

 lique and very prominent; fl. large, \\ in. or rather more diam., 

 ped. long, glabrous, solitary or 2 together, from axils of upper 

 1, ; sep. lanceolate, acuminate ; lip boat-shaped, acuminate ;
