SOUTH AMERICAN PEANTS. 13 
ment of some species of Cestrum, which appears as if two 
lateral lobes were agglutinated into one salient tooth. 
The following is proposed for its generic character : 
Dunauia Kunth. (char. emend.)—Caly# urceolatus sub- 
pentagonus, 5-dentatus. Corolla hypogyna longe tubulosa 
10-nervia, limbo 5-fido, lobis estivatione marginibus floc- 
cosis vix induplicatis basi plicatis, dente mucronato erecto 
interjecto. Stamina 5 corolle tubo inserta, inclusa vel 
exserta, filamentis basi dilatatis et pubescentibus, linea 
centrali tubo adnatis, marginibus membranaceis liberis, 
superne glabris, omnino liberis, 3-partitis, laciniis latera- 
libus linearibus acutis erectis, intermedio gracili antheri- 
fero; antheris oblongis, 2-lobis, basifixis, longitudinaliter 
dehiscentibus.—Ovarium ovatum, 2-loculare, placentis cras- 
sis dissepimento adnatis, multi-ovulatis. Stylus simplex 
exsertus. Stigma eargimnato-capitatum. Bacca globosa, 
ealyce suffulta, 2-locularis. Semina plurima, reniformia 
compressa. Embryo ignotus. 
Frutices Andicoli Americe meridionalis intertropice ; foliis 
alternis petiolatis, geminis vel fasciculatis, glabris vel pubes- 
centibus; floribus subumbellato-fasciculatis vel solitariis, 
 extra-axillaribus : corollis albis vel coccineis. 
1. Dunalia solanacea, HBK. 3.55. tab. 194. Dierbachia sola- 
nacea Spreng. Syst. 1.676.—inermis: ramulis tomentosis ; 
foliis alternis, ovato-oblongis, acuminatis, basi ineequaliter 
rotundatis, supra glabris, subtus incanis, stellato tomen- 
glabris ; floribus solitariis, nutantibus ; calyce late campanulato, 5-den- 
~ tato, 2-plo,3-plo-ve longiore, corolla violacea, staminibus inclusis.— 
Peruvia, circa Pisacomam, altit. 15,000 ped. 
A handsome shrub, said much to resemble the last mentioned species, 
but differing in its smaller lanceolate leaves ; branchlets covered with thick 
white tomentum, 1-12 in. long, often spiny at the apex, bearing fascicles 
of leaves at the base; peduncles axillary, smooth, 6 lines long; calyx 
smooth, 3 lines long, with 5 short equal obtuse teeth, terminated by a 
woolly cuspidate point ; corolla tubular, 15 lines long, with a slightly 
spreading border, having 5 short triangular acute lobes with ciliate mar- 
gins ; berry red, twice the size of a pea, globose, partly enclosed within 
the calyx, which now becomes unequally 3-4 cleft. “gy
