In addition to the species enumerated by Mr. Bcntliam in 

 DC. Prodr. x. 197 et 590^ and the B. speciosa of Sir Win. 

 Hooker^ Bot. Mag. tab. 4339^ I have now to mention two others 

 yet undescribed : 



Browallia tenella (n. sp.); — herbacea, hnmilis^ parce puberula^ 

 foliis membranaceisj lanceolatis^ vel ellipticis^ in petiolum elon- 

 gatum cuneatia; floribus paucis, solitariis^ axillaribns^ calycis 

 membranacei dentibus laiiceolatis^ obtnsis, insequalibns j co- 

 roUse tubo gracilis calyce 4-plo longiore^ limbo brevi^ plano^ 

 sinuato-pentangulato, lobis brevissimis, emarginatis^ rotnn- 

 datis^ antico majori ; ovario apice piloso. — Rio de Janeiro. 



This species, which I found growing at Pertininguy in 1830, 

 has very much the habit of B, demissa^ but is readily distin- 

 guished by the much greater length of the petiole, fewer flowers, 

 a more slender corolla with a much narrower border, a more 

 membranaceous calyx with less prominent nervures, and by the 

 simple hairs and almost obsolete pubescence of the whole plant. 

 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 1^ inch long, | inch wide, upon a very 

 slender filiform petiole of | inch ; the peduncle of the flower is 

 barely 2 lines long, growing to a length of 7 hues ; 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*. 



Browallia nervosa^ n. sp. ; — foliis ellipticis, acutis, in petiolum 

 longiusculum canaliculatum attenuatis, ciliatis, utrinque spar- 

 sim scabrido-pilosulis, penninerviis, nervis subtus prominulis, 

 floriferis fere bracteiformibus ; floribus axillaribus laxe sub- 

 racemosis; calyce parvulo, angustato, cylindrico, dentibus 

 acutis, erectis, ciliatis, nervis 10 violaceis picto, glabro ; corolla 

 hypocraterimorpha, tubo angusto^ calyce 2-plo longiore, limbo 



* A figure of this species with generic details is shown in plate 54 of
