lato, planOj violaceo^ lobis hrevibus emarginatis ; ovario ob- 

 ovato, apice piloso. — Ecuador, v, s. in herb. Hooker. (Villa Sa- 

 saranga, prope Loxam). Seemanriy no. 740. 



This plant is intermediate with B, peduncularis and B. grandi- 



markably contracted form of its calyx and peduncle. It differs 

 also from B. demissa by its leaves being more acute at their base, 

 with a comparatively longer and more winged petiole, and by its 

 more racemose flowers. The leaves are 1^ inch long, 8 lines 

 broad, on a petiole half an inch in length, with the coriaceous tex- 

 ture and general appearance of those of B. peduncularis. The 

 calyx, having five short pointed erect teeth, is at first extremely 

 narrow, 4 lines long, | line in diameter, swelling 'to a much 

 larger size in fruit j the tube of the corolla is 8 lines long, 

 I line in diameter, slightly swollen below the very narrow mouth ; 

 the border is large in proportion, quite plane and rotate, 9 lines 

 in diameter, and of a purple colour ; the capsule, 3 or 4 lines long, 

 is hairy at the summit of its bifid valves. 



It appears desirable to divide the species of Browallia into two 

 sections ; the fii'st including those Avhose corolla presents a plane 

 border, with short eraarginate lobes, and an ovarium with its 

 upper moiety densely covered with long white hairs, which are 

 even persistent on the capsule ; the second will comprise such as 

 do not possess these characters, and is confined at present to a 

 single species : thus

larger flowers of this species, its more acutely-lobed and deeper- 

 cleft border, and constantly smooth ovarium, are characters of 

 hardly sufficient importance to constitute a generic difference j 

 but at all events, with such marked distinctions, Leiogyne will 

 form a good subgenus.
