A glabrous variety of Sagina subulata (Sw.) C. Presl in Britain

Summary Recent inspection of British herbarium material of Sagina saginoides (L.) Karst. and S. subulata (Sw.) C. Presl has revealed a glabrous variety of the latter which has frequently been misunderstood by British botanists. This paper aims to point out the reasons for the confusion and give distinguishing characters for the taxa involved. The distribution of the variety, so far as it is known at present, is also discussed.
