Some Additional New Names for North American Mosses (1965)

Fifteen nomenclatural changes are proposed in connection with a revision of Grout's 1940 checklist of North American mosses. Last year we published (Crum et al. 1964) a list of some nomenclatural changes found necessary during the preparation of our checklist of North American mosses that appears in this issue of THE BRYOLOGIST. The present paper gives a few additional nomenclatural changes of the same nature. Drepanocladus fluitans (Hedw.) Warnst. v. uncatus Crum, Steere & Anderson nom. nov.

Muse. Eur., ed. 2. 697. 1876. Mr. Robert R. Ireland has examined the type of Isopterygium borrerianum and he has kindly informed us that it fits his concept of I. elegans (Hook.) Lindb. Although the latter is the oldest name, it is invalid because of a previous homonym. Lindberg (1874), who previously examined the original collection 'of I. borrerianum, concluded that it is not the same thing as I. elegans. Ireland has studied the problem with his usual care and good judgment, and we are inclined to follow him.
