O b s .—This may he the Jung, excisa of Dickson (PI. crypt.
Brit. fasc. 3, 1 7 9 3 ), as Lindberg asserts, but his description and
figures are vague and incorrect, so I prefer to adopt the very
characteristic name of Hooker.
Distinguished from Jung, ventricosa,, Dicks., by its paroicous
infioresoenoe.
