the perianth, which is so completely exserted as to appear almost stipitate; 
the perianth itself is pyriform, inflated and obscurely 4-5 plicate only at the 
very apex, with a mouth connivent, denticulate. This genus shows two 
methods of reproduction, first, by the branching of shoots and the dying of 
the stem in between, and second, producing gemmae on the tips of the leaves. 
The first method is very limited in L. infiata , stems with fertile perianths 
and those with androecia, also those' sterile are generally unbranched ; while 
one or two subfloral innovations are to be found on stems with unfertilized 
perianths ; no gemmae are found on this species or its variety and it was 
difficult to understand its wide-spread (distribution. 
Right here I would like to refer to a very interesting paper on Lophozia 
infiata by. fieri* Schiffner, published in Ascherson’s Festschrift* A trans- 
lation of this was very kindly furnished me by Miss J. T. Emerson. Dr. 
Evans, in calling my attention to this* paper summarized it as follows: “the 
deciduous perianths in L. infiata really represent organs of vegetative repro- 
duction, new shobts arising from their cells', and he finds that they serve the 
same purpose in var. heterostipa but not in C. fluitans .” Schiffner says that 
these easily detached perianths are produced ip great profusion and develop 
normally to the point where the fertilization of the enclosed archegonia takes 
place; at this stage it is impossible to foretell whether they will become fertile 
or so called sterile perianths. The slightest touch sufficing to break off these 
latter, their buojmncy keeps them afloat and they are carried off, some to the 
shore to which they attach themselves and start growing, sending out 
rhizoides and shoots which when mature are the typical infiata. 
The illustrations were , made from fresh material furnished me by the 
following : Miss Lucy MacIntyre, the A. infiata , collected in a bog at Long 
Branch, New Jersey. The abundant perianths were very deciduous, the 
plants were growing with Rdllavicinia Lyellii (Hook.) S. F. Gray; the 
var. heterostipa was collected by Mr. A. S. Foster at Hamilton, Wash., and 
was growing with Mylia anomala (Hook.) S. F. Gray, this latter species 
being new to this state; Miss An nib Lorenz and Mr. E. B. Chamberlain, 
collected the C. fluitans in New Hampshire and Maine, respectively. All 
these specimens form part of our Chapter Herbarium and it is hoped that 
students will be on the lookout for these tiny and interesting species and 
contribute duplicates of their finds. /
