206 Mr. J. Miers on the genus Browallia. 
It is remarkable as being the first instance of any species grow- 
ing so far to the southward of the equator and upon the eastern 
side of the continent. It is scarcely more than 6 or 8 inches 
high, with a very slender and almost glabrous stem, but little 
branched ; its leaves are 14 inch long, 2 inch wide, upon a very 
slender filiform petiole of 3 inch; the peduncle of the flower is 
barely 2 lines long, srowing toa ‘length of 7 lines; the tube of 
the calyx is 2 lines long, with teeth scarcely a line in length ; it 
is cylindrical, = line in diameter, growing to a length of 4 lines 
in fruit and a diameter of 2 lines, wholly enclosing the capsule ; 
the tube of the corolla is very slender, 8 lines in length, of a 
greenish lurid white ; the border is 4 lines in diameter, at first 
of a pale bluish colour, afterwards becoming of a violet hue. 
The internal structure of the flower, capsule and seeds entirely 
agrees with that of the typical species*.

This plant is intermediate with B. peduncularis and B. grandi- 
flora, from both of which it is evidently distinguished by the re- 
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 14 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, 2 line in diameter, swelling to a much 
larger size in fruit; the tube of the corolla is 8 lines long, 
2 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 first including those whose corolla presents a plane 
border, with short emarginate lobes, and an ovarium with its
