To resume the question of affint ' My own crude reference 
of S. ligulata to Encalypta is at once nies aside—now that the fruit 
of a closely-allied species is known—by its small dimidiate 
calyptra ; besides by its lacking the veaiée cloven papille that stud 
the leaves of Encalyptas. 
Miller (‘Synopsis a a. 1851 ), who rere he had 
pent tees proved it a Zygodon: a genus, however, which taken 
even in widest acceptation) differs from popraest in its 
papitlowés eae idete, sharp-pointed leaves, and in its long- 
necked, ribbed, exannulate capsule. I do not know ‘of pierre 
further having been published respecting it until it fell to Mr. 
Mitten’s lot to describe the South-American species, as abe ve

Whatever may be rece of Mitten’s “* Weisia,” in the aggregate, 
. * Mr. Mitten has a second species, Weisia (Scop.) cataracte, n.sp., gathered 
by myself in the same locality, and probably about the base of the fall, where it 
was kept perpetually moist. It is a o differ from goyanensis in the 
subacuminate leaves, with a shorter pellucid base ; but I have no specimén of it, 
and can give no opinion on its specitic merits. 
All these se seem to me closely related, and not unnaturally combined 
into a single genus, except the last, ti inodon, Mitt., which is a very curious

described it as a new genus, Splachnobrywm, referring it to the tribe Splachnacee, 
and adding some new species; and there is no doubt that his name—claimi ing at
