This interesting plant very much resembles Parnassia Faberi, 
Oliv., the chief difference being its very distinct staminodes. As 
these are not alluded to in the original description in Fedde, Re- 
pert. Nov. Sp. Band xiii (1914), p. 258, the present emended 
description is necessary. ‘The collectors’ notes attached to the 
three gatherings of the plant, all now in Herb. Edin., are also 
given : in the original description the number of the type is 
misquoted.
