long, with pellucid dots, covered on every part, like the stem? 

 Hvith short, rather stift" hairs, indistinctly mucronate at the tip j 

 under side marked with the prominent midrib, ard with 2 ob- 

 scure lateral nerves. Peduncles axillary, forked ; each division 

 bearing 3-flowers on short footstalks. Corolla purple; seg 

 ments acute. Fruit covered with uncinate bristles. 

 Hau. In dry woods ; rarely in meadows ; not common. July- 

 August. Resembles the G. rotunclifolium of Europe. 



Muhlenberg and Elliott refer to this species the G. 

 puncticulosum-f of Alic h aux, while Purs/i makes it a 

 variety of his G. bermudianum. It is also considered by El- 

 liott as synonymous wiiii G. purfiureum Wa 1 1. which is de- 

 scribed with the leaves smooth. I have not the means of re- 

 moving this confusion.

 ternate. Corolla dark purple ; segments cuspidate. 



Hab. In shady rocky woods. June — July. 



I have, from Connecticut, what appears to be a variety of this 

 species. The whole plant is very hairy, and the leaves are 

 covered with pelhicid dots; in every other respect it resem- 

 bles G. circcezuns. Can it possibly hePurs/i's G. bermudi-
