libus, rarius oblongis, acutis, antico paulo majore, estivatione 
reciprocativa ? Stamina 4, didynama, inclusa ; fi/amenta brevia, 
2 antica inferiora, sublongiora, hemicyclice curvata, imo dila- 
tata, apice expansa, inflexa et pilosa ; anthere sagittato-bilobe, 
inverse, lobis ovatis, rma marginali dehiscentibus, superiorum 
lobo altero minimo casso. Ovarium obovatum, apice pilosum, 
inferne glaberrimum, sepe stipitatum, rarius omnino glabrum, 
2-loculare, placentis carnosis prominulis dissepimento utrinque 
adnatis, multi-ovulatis. Stydus simplex, apice incrassatus, in- 
flexus, transversim rugulosus. Séigma dilatato-bilobum, lobis 
emarginatis altero majore, intus septis cruciatim in locellis 
4 stigmatosis divisum. Capsu/a membranacea, calyce per- 
sistente tecta, 2-locularis, 2-valvis, valvis bifidis, dissepimento 
tenuissimo demum libero parallelis. Semina plurima, minuta, 
obovata, lateribus angulata, dorso convexa, ventre concava et 
infra medium hilo notata ; testa reticulato-foveolata. Embryo 
in axi albuminis carnosi homotrope subincurvus, cotyledoni- 
bus ovatis, compressis, radicula tereti infera 3-plo brevioribus 
et 2-plo latioribus.—Herbz <Americe intertropice indigene, 
plus minusve viscido-pubescentes. Folia alterna, integra. Flores 
ad axillas foliorum superiorum solitari, cum petiolis sublate- 
ralibus, interdum foliorum minutione in cymas irregulares termi- 
nalibus dispositi ; pedunculo florifero brevi, interdum fructifero 
mox elongato ; corolla violacea, cerulescens, aut albescens. 
In addition to the species enumerated by Mr. Bentham in 
DC. Prodr. x. 197 et 590, and the B. speciosa of Sir Wm. 
Hooker, Bot. Mag. tab. 4339, I have now to mention two others 
yet undescribed :— 
Browallia tenella (n. sp.) ;—herbacea, humilis, parce puberula, 
foliis membranaceis, lanceolatis, vel ellipticis, in petiolum elon- 
gatum cuneatis; floribus paucis, solitariis, axillaribus, calycis 
membranacei dentibus lanceolatis, obtusis, inzequalibus; co- 
roll tubo gracili, calyce 4-plo longiore, limbo brevi, plano, 
sinuato-pentangulato, lobis brevissimis, emarginatis, rotun- 
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.
