Notes

Synonym of F. altaica. In examining the isotype and possible second isotype collections of Drummond from GH, in 1994, (see image library) the first author agreed with the annotations made by L.E. Pavlick (Sept. 1981) that these specimens are plants of F. altaica sensu stricta. F. scabrella var. major Vasey = F. campestris Rydb., F. scabrella Torrey in Hook. subsp. hallii (Piper) W.A. Weber = F. hallii Vasey.
