Concerning the Sleepy Grass of New Mexico, for which informa- 

 tion was asked on p. 40, supra, Mr. F. V. Coville, Botanist to the 

 Department of Afi;riculture, A¥ashington, D. C, writes that the 

 plant in question is Stipa viridiila robusta. 



Fritillaria pluriflora, Torrey, is figured in the Gardener's 

 Chronicle for April 10 (vol. xxi, ser, 3, p. 231, fig. 76). It 

 appears to have flowered recently under cultivation in Ireland. 



Prof. J. W. Toumey contributes to Garden and Forest for 

 April 21, 1897, some interesting "Notes on the Pine Forests of 

 Southern and Central Arizona," with estimates of the number of 

 square miles of forests on the principal ranges. The forest area of 

 Arizona south of the Colorado plateau is said to be about 600 square 

 miles. The total area of Arizona south of this plateau is about 

 75,000 square miles, making it thus appear that the pine forest area 

 of southern Arizona is considerably less than one per cent of the 

 entire area. In the same number of the above journal, Mr. Carl 

 Purdy, of Ukiah, has a note on Erythronium grandijiorum and 

 related species. 



In the Bulletin of the Torrey Club for April, Mr. M. A. Howe, of 

 Columbia University, founds a new genus of Hepaticse, which he 

 calls Gyrothyra, containing a single species, G. Underwoodiana. 

 The material studied was collected by the author near Eureka, 

 California, and by Macoun in British Columbia.
