Gen. V. SWERTIA. 



SWERTI^ SP. L. 



Calyx profunde 5-partitus. Corolla 5-partita, rotata, persistens : segmentis 

 basi biglandulosis : glanduUs dilatatis, callosis, margine fimbiiatis. Stigma 

 bilobum. Capsula compressa, Crustacea, l-loculai'is. Semlna parietalia, 

 oi-biculata, complanata, margine niembranacea. 

 Herbse (Europse et Asise frigidioris) perennes. Folia nervosa, quandoque al- 

 terna ! Flores termlnales et axlllares, suhsolitarii v. racemoso-paniculati, 

 ccerulei aut lutei. 

 A very natural and well-defined group, consisting of Swertla perennis, oh- 

 tusa, and tbe 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 alternifoUa exhibit in their alternate leaves a remarkable 

 peculiarity in this family, closely approximating by this character and also by 

 their fringed petals to the Menyanthea;.
