1 T. naevosum Dahlst. var. biþinnatifidum (Rostr.) Dahlst., in C. H. Ostenfeld :
Additions and corrections to the list of the Phanerogamae and Pteridophyta of the
Faeroes, 1905, p. 841 and T. obliquum Fries, var. bipinnatifidum Rostr., Færoernes
Flora, 1870, p. 51, seems to be identícal. The shape of leaves and of the fruit is
like those of T. hoþlites. T. biþinnatifidum (Rostr.) Dahlst., Trans. of the bot. Soc.
of Edingb., vol. XXIX, part IV, 1927, p. 416, does not belong here. The fruits
of the latter has quite another shape, it is only warty, not long toothed on the
summit; and the leaves are purple-spotted.
