Cuar. Gen. Calyx basi breviter adnatus, limbo 5-partito. Corolle tubus subzequalis, exsertus, 
declinatus ; limbus obliquus, patens, 5-fidus.—Stamina 4, didynama, cum rudimento quinti; anthere 
liberee, subrotunde. Glandule perigyne 5. Stylus apice bilamellatus, lobis membranaceis intus 
stigmatosis. Capsula unilocularis, valvulis 2 medio placentiferis, Semina numerosa. 
Herba tenera, flaccida, semipedalis vel vix pedalis, ramis paucis divaricatis villosulis. Folia opposita, 
longiuscule petiolata, ovata, obtusa, crenata, basi rotundata vel angustata, 2-3-pollicaria, tenuiter membranacea, 
supra hispida, subtus pallidiora, glabra vel ad venas villosula. Racemi in axillis superioribus solitarii vel 
terminales, folio seepius breviores. Pedicelli oppositi, filiformes, 6-10 lin. longi, singuli bractea ovata sessili 
1}-2 lin. longa subtensi. Calyx 14 lin, longus, viridis, fere glaber, lobis ovatis vel oblongis obtusiusculis parte 
integra adnata longioribus, Corolla semipollicaris, leviter pilosula. Stamina inclusa, antheris parvis globosis. 
Glandule perigyn inter se aquales, lineares, ovario longiores. Capsula calyce brevior, basi adnata. Semina 
numerosissima, minuta (albumine parco?), in speciminibus nondum matura. 
The free stamens of this plant indicate an affinity with Achimenes, and the 
form of the corolla is not unlike that of some of the small-flowered species of that 
genus, but the tube is neither gibbous nor spurred at the base, and the five equal 
perigynous glands are more prominent even than in Gesneria and Gloxinia. It is 
not improbable, however, that the Achimenes erinoides, DC., and A. comifera, DC., 
may be congeners of our plant.
