NOTES ON BUXBAUMIA. 



Mr. R. S. Williams, who has a note on Bu.xbauinia in the Journal of the 

 New York Botanical Garden for July, 1900, and another in the Bulletin of the 

 Torrey Botanical Club for August, iguo, states that we have three good 

 species in the United States, B. iiuiusiata, Brid., with two-celled superficial 

 stomata, and two others. B. aphylla L., and B. Tiperi 'Qi^st. with one-celled 

 immersed stomata. The first two range across the continent, the last has 

 not yet been found east of the Rockies. 



This distinction between our two eastern species will be welcomed by 

 those who have had difficulty in determining them. This distinction is 

 easily (observed by mounting a portion of the wall of the capsule near the 

 base. This distinction is explained and illustrated in the conclusion of the 

 Illustrated Glossary in this number 



Mr. Williams has collected B. aphyl la in fhe New York Botanical Gar- 

 den. He states that, in his observation, Bu.xbaiiiiiia always grows on rotten 

 wood or soil containing fragments of rotten wood. — A. J. G. 



Mr. Windle"s note in the October Bryologist on Bu.xbauinia apltylla 

 was very interesting to me, because it tallied very closely with my experi- 

 ence with that interesting species. He spoke of finding the plant in an 

 immature state December ist, and as having shed its spores by March ist, 

 which I think is almost always correct. But this year I collected it on the 

 trunk of a tree in perfect fruit, with not a spore shed, September 15th. In 

 1S99 I collected my material February ist, and in 1900, January ist. I have 

 found this moss in four localities in Amesbury, Mass. Every one of these 

 locations is on the north side of a hill, as thev were in Mr. Windle's find. I
