Comment/Acknowledgements:
In treatments of C. infuscata and related species of sect. Atratae subsect. Alpinae (Kalela in Ann. Bot. Soc. Vanamo 19,3, 1944), position of staminate flowers in spike has been emphasized (e.g. Raymond in Koeie & Rechinger, Dan. Vidensk. Selsk. Biol. Skr. 14, 4: 5-35, 1965). For example, staminate flowers are said to be at the top of spikes in C. trispiculata Boeck. (holotype from India, Garhwal, Schlagintweit 10056 BM!), but this could not be confirmed in the material seen. It appears that less emphasis should be given to this character in sections Atratae and Aulocystis. Accordingly, Bowes Lyon 166, Chitral (BM), cited by Stewart (1972) under C. gracilenta Boott, is included here into C. infuscata.
