In both the female inflorescence is either ventral ( gastrogyna) 
or terminal (acrogyna). If terminal, it may continue so when the 
stem does not innovate, or, by the growing out of innovations 
from both sides beneath it, it becomes apical in the dichotomia 
(confer the cyma of higher plants), or soon lateral by the growth 
of a branch under it, either repeatedly alternate from both sides 
of the stem (confer the circinus, *cyme scorpicide unipare’’), or 
repeatedly from only one side (confer the bostryx, “ cyme hélicoide 
unipare”). But axillar true perichetia, as in pleurocarpous mosses, 
seated in the axils of true vegetative leaves, and always composed 
of no more than a very short axis, bracts, colesula and pistillidia, 
T have never found in the Liverworts. Such short female branches 
take their origin only from the axils of the amphigastria ; 7. e. they 
are always ventral. The male inflorescence (andrecium) has in 
most the same position as the perichetium of the same species. 
These notes are indeed very fragmentary; but they may suf- 
fice for the present, as showing that the question is highly inter- 
esting and deserves its own special chapter. 
May I be allowed to finish this little paper by a relation of my 
views as to the reciprocal position of the Liverworts and Mosses 
in the system of Muscineæ. I must then try to answer the ques- 
tion which of the two may be considered more highly developed? To 
give here a detailed exposition of the matter would be tedious; 
and I must limit myself to the chief points. 
And first I must claim for the system of vegetation a nearly 
exelusive right of decision as to the highest divisions amongst the 
Hepatice and Bryinee, because, in regard to their natural ar- 
rangement, the fruit and its different parts are of use and import- 
esting letter from Dr. Gray ; he says that a friend of his, named Bennett, a — 
promising young botanist, who died carly, undertook the Hepatica in Gray’s 
‘Nat. Arr" In Saccogyna the leaves are opposite and connate by means of 
the interjacent amphigastrium, so that all three become coherent.
