NOTES. 



— The leading article in Rhodora for September, is entitled, 

 "Ferns of Alstead, New Hampshire." It consists of notes on 

 about thirty of the commoner ferns. 



— A new Botrichium — B. pumicola — is described in the re- 

 cently issued sixth edition of Underwood's "Our Native Ferns,' 

 by Mr. F. V. Coville. It was found at Crater Lake, Oregon, in 

 pumice soil and is nearly allied to B. tenebrosum and B. simplex. 



— Mr. L. F. Henderson has described a new species of Isoetes 

 from Idaho, in the Bulletin of the Torrey Botanical Club for 

 June, under the name of /. occidentalis. It grows a foot or 

 more under water and is closely related to / lacustris — " per- 

 haps too near for specific delimitation "—the author says. It is 

 reported to be common in many lakes of the Northwest. In the 

 same place is described a variety of /. Bolanderi which is 

 named Sonnei. It was collected in Donner Lake, California. 



— The North American species of Lycopodium have recently 

 received attention at the hands of Professors L M. Underwood 

 and F. E. Lloyd, whose conclusions, published in the Bulletin of 

 the- Torrey Botanical Club for April, show several more species 

 added to the number within our limits, bringing the total up to 

 seventeen. The ranges of those already known are also more 

 clearly defined. Lycopodium porophyt Hum, very near L. lucidu- 

 lum, is described as new and credited to stations in Wisconsin, 

 Indiana, Kentucky and Alabama. Two forms that were once 

 considered as varieties of L. inundatum are raised to specific rank 

 as L. adpressum and L. pinnatum. Of the former the authors 

 say: " It must be admitted that from the true boreal species, L. 

 inundatum, to the large southern L. adpressum, there are many 

 forms which, on account of variations in size of stem, denticula- 

 tion and variation in the size and shape of leaf and sporophyl, are 

 difficult to place." To the latter variety is apparently referred 

 the plant recorded from Plum Island, off the coast of Massachu- 

 setts, as L. alopecuroides. Of true alopecuroides, the farthest 

 northern specimens were found by the editor of this journal in 

 1898 at Babylon, Long Island. L. Site he use, a plant of the North- 

 west, related to L. sabinafolium, is recorded as occurring in 

 Maine, Labrador, New York and Ontario. A species from 

 Jamaica allied to L. compianatum is named in honor of Hon. 

 William Fawcett, Director of the Public Gardens of Jamaica.
