Spruce, in Trans. Bot. Edin., Vol. III., p. 212,
decided that the Jungerinannia minutissima of
English Botany and of Hooker’s pi. 52) belonged
to L. ulicina Tayl., and that the Jungermannia
minutissima Tayl. should be called Lejeunia
Taylori Spruce. Since then his opinion changed,
and he refers the English Botany figure to his
Lejeunia Taylori, otherwise Lejeunia inconspieua
Raddi.
