The slender stem and peduncle do not exceed 2 dm. in height ; 

 the leaves are 3-5 cm. long and evidently petioled. The material 

 available for examination is in poor condition, and the species is 

 associated with T nivale and T undulatum from Watson's state- 

 ment alone. The stigma is said to be short, and the ovary nar- 

 rowed at the tip ; in both of these characters it is quite unlike T. 

 nivale.
