O b s .— Under this name I have grouped all the small forms of
what were considered Jungermania acuta, Lindenb., which are
without stipules ; the form published in G. & R. n. 043 as Jmg.
acuta is the same as a form named Jung, turbinata var. acufiloha,
Spruoe, whieh connects Jung, turbinata with Jung, bantriensis var.
Muelleri. Jung, turbinata is a very constant form and may be
regarded as the extended type of a group with Jungermania
bantriensis, Hook., at the other extreme.
I t may be distinguished from other dioicous species by the
antical segment at the base of the upper leaves and bracts, its
delicate cell structure and the turbinate perianth.
