flowering plants where the same species may be either monoicous or dioi- 
•cous. And in at least one species, Arisaema triphyllum, the same indi- 
vidual varies from season to season. 
In the Revue Bryologique for January, 1904, M. Corbiere, in an article 
entitled, Sur quelques Muscinees de Maine-et-Loire, gives striking confirm- 
ation of my previously formed opinions. He states that he himself, as well 
as Schimper, De Notaris, Husnot, Boulay, Braithwaite and Limpricht, has 
recognized that Bryum pallescens might be either monoicous or dioicous. 
But studies on the plants from the region [mentioned in his title brought to 
light some exceedingly interesting facts in addition. The first plant studied 
had three inflorescences, the terminal was exclusively female, at the base 
were two equal branches, one of which was exclusively male and the other 
mixed, synoicous ! Another plant had at its summit a mixed inflorescence 
and of its three branches two were male and the other mixed. 
Here is an interesting field for our Sullivant Chapter members. Exam- 
ine hundreds of specimens of mosses of some common species for variations 
in the arrangement of archegonia and antheridia, keep a record and report 
to us the results. I am confident that such variations will be found in suffi- 
cient number to “ reduce” several species, 
SOMETHING NEW ABOUT BUXBAUMIA. 
Early in March, Miss E. B. Brainerd, Secretary of the New York Natu- 
ralists’ Club, sent me two fine healthy plants of Buxbatimia aphylla with a 
large lump of soil in which they were growing. As they were the first fully 
developed fresh capsules I had ever seen I put them in the window and kept 
the soil moist, hoping to see the opercula fall and test the theories of spore 
dispersal. But, alas, one morning when I went to visit my pets they were 
gone. The earth was there but the Buxbaumia was not. The conditions 
were such that only one answer could be given. Mice having tired of our 
table delicacies had dined off Buxbaumia. A. J. Grout. 
NOTES ON RARE OR LITTLE KNOWN MOSSES. 
Alsia abietina Sulliv. 
Recently I received a letter from Prof. Roll, of Darmstadt, enclosing a 
bit of Alsia abietina in fruit, which he collected some time ago at Tacoma, 
Wash. He found it upon an oak tree. In an article in Hedwigia he spoke 
of having collected it here but he omitted mentioning that it was in fruit. 
From an article I published in the Bryologist (6:3, 1903) it might be inferred 
that the moss did not fruit here. It is a pleasure to correct any wrong 
impression which my article may have created, and I wish to thank Prof. 
Roll for his interest in the matter. Dr. John W. Bailey, 
Seattle, Wash. 
Buxbaumia aphylla L-. 
While collecting along Crum Creek, Delaware Co., near Philadelphia, 
Pa., on April 27, 1902, I came unexpectedly upon a small colony of Bux- 
baumia aphylla. I overlooked them at first, taking them for the bud scales 
of the beech tree ( Fagus Americana Sweet) which their capsules resemble 
somewhat at a glance. They were growing on the northern exposure of a
