T h e n a tu ra l affinity o f th is p lan t svith th e two species Ju s t men tio n ed is very s trik in g
even to a superficial obse rv e r; m ore parUeularly to th e former o f th em , from which however’
i t essentially differs in th e g r e a t len g th and in th e incurved segments o f th e leaves, as well
as m th e e re c t (and hy no means recurved) apices o f th e perichæ tia i leaves. T h e places o f
grow th , too, o f th e th re e p lan ts a re widely different ; th e p re s en t species seeming to be

We owe o u r first a cquaintance Avith this Jungermannia, as weU as Avith th e one la s t described
( J . connivens) to th e acuteness o f Mr. Dickson. T h e figure given in English Botany does n ot
exlubit th e leaves so much incurved as is th e case in my specimens; and, indeed, th e whole p lant,

it to do.
