basi biglandulosis : glandulis dilatatis, callosis, margine fimbriatis. Stigma 
bilobum. Capsula compressa, crustacea, 1-locularis. Semina parietalia, 
orbiculata, complanata, margine membranacea. 
Herba (Europee et Asiz frigidioris) perennes. Folia nervosa, quandoque al- 
terna! Flores terminales et axillares, subsolitarii v. racemoso-paniculati, 
cerulei aut lutei. 
A very natural and well-defined group, consisting of Swertia perennis, ob- 
tusa, and the species here described, and characterized by its flat orbicular 
winged seeds, and by the fringed nectariferous glands at the base of the petals. 
Nearly related to this genus are Asterias (Gentiana lutea, L.) and Frasera, the 
former distinguished by the naked glands of its petals, and long narrow stig- 
mata, and the latter by its deciduous corolla and marginal placentation. 
The S. obtusa and alternifolia exhibit in their alternate leaves a remarkable 
peculiarity in this family, closely approximating by this character and also by 
their fringed petals to the Menyanthee.
