Analyses of miscellaneous
materials of green-gemmous Lophozias have shown: (1) L. silvicola
is a distinct species from L.ventricosa. (2) L. iremelensis is
synonymous with L. ventricosa and treatment of the former as conspecific
with L. wenzelii is erroneous. (3) Jungermannia groenlandica is a
distinct variety of L. wenzelii. (4) The separating of the sect. Guttulatae
is unfounded because of absence of constant defining features from sect. Lophozia.
So, sect. Guttulatae should be rejected. (5) L. silvicoloides
seems to be a more or less common species of East Siberia and Far East with a
few disjunctions in Europe. The species is close on the one hand to L.silvicola
and on the other hand to L. ascendens. Two new combinations are
proposed: Lophozia ventricosa var. guttulata (Lindb. et H. W.
Arnell) Bakalin comb. nov. and Lophozia wenzelii var. groenlandica
(Nees) Bakalin comb. n. The key for identification of Holarctic’s green-gemmous
Lophozias is presented.
