owing to the presence of chlorophyll in the tissues. With the warm days of late 

 February or early March, growth begins again, and the color changes from green 

 to brown as the plants mature. Usually by the middle of March or the first of 

 April the spores are ready for dispersion. Sometimes in sheltered spots the 

 capsules remain unbroken until summer. The spores may germinate at once, 

 giving rise to a protonema which is in no way peculiar among the mosses. 



Some authors have used the word " pseudopodium " in describing the seta 

 of Biixbatiuiia. This term, as applied to Sphaffuion and Atidreaea, indicates a 

 prolongation of the a.xis of the leafy gametophore, which bears the sessile cap- 

 sule at its ape.x. The pedicel of Bu.vbainnia is, on the contrary, a part of the 

 sporophyte as in the other Bryineae, and is, therefore, a true seta, with its lower 

 end imbedded as a foot in the tissue of the much-reduced gametophore. 



Buxbaui>iia indusiata Brid. also occurs with us, but is much rarer than B . 

 aphylla. I first met with this species in October, 1893, in Enfield ravine, one of 

 the largest of our glens. Since then it has been collected at a half-dozen other 

 spots in the same gorge. In fact, I seldom visit this interesting place without 

 seeing a few capsules. More recently I have found plants at single stations in 

 both Buttermilk Ravine and Coy Glen. Besides these, I have seen specimens 

 kindly sent me by Professor Dudley, and collected by him in Fall Creek and 

 Cascadilla ravines, the latter station being actually on the University campus. 

 We have thus within eight miles of Ithaca five different stations for this species, 

 but, although 1 have searched the region pretty diligently, no others have been 

 found. 



With us B. indusiata always occurs on very rotten moist logs and stumps, 

 often along with liverworts and other mosses. The wood is usually so badly 

 decayed that it may be picked to pieces with the fingers. The individuals occur 

 singly and widely scattered, and are very hard to see. The whole habits of our 

 two eastern species are so totally different that no one ought to have the slight- 

 est difficulty in distinguishing them even without the aid of stomata. I have not 

 been able thus far to obtain much information regarding the development of the 

 rarer form. I have collected it only in the fully or nearly mature state, in Octo- 

 ber, November, December, April and May. Specimens may be found on the 

 same log year after year. — Botanical Department, Cornell University.

Bu.vbauinia aphylla has the reputation of disappearing from its recorded 

 stations, but on one old stump in the Hemlock Grove, in Bronx Park, I have 

 collected it for four years successively, and last year there were as many as fifty 

 fruiting plants. These did not come to maturity, nowever, as the first freezing 

 cold weather killed all but a few. There was no snow to protect them. The 

 pedicels remained for a year later. By the beginning of September, five new 

 stalks were found; these had developed green capsules by November, and when 

 last seen were still growing. This year there has been snow to cover them, and 

 I took care to give them shelter with a few hemlock boughs. Mr. Williams 

 found onl> two capsules growing out of the end of a "decorticated log," little 

 decayed, and with no other mosses growing with them. It is the most unusual 

 record for this species.
