GENERAL NOTES. 



SONORELLA WOLCOTTIANA A CORRECTION. 



Owing to an oversight in proof reading of the description of Sonorella 

 walcottiana, Proc. Hiol. Soc. Wash., Vol. XVI, pp. 103-104, June 25, 

 1903, the name appeared as above. The species was named in honor of 

 Mrs, H. L. T. Wollcott, the collector, and the name should read Sono 

 rella wolcottiana. Ptful Bartach. 



THE SPECIES OF GEUM OCCURRING NEAR WASHINGTON. 



Four species of Oeum are said by Ward (Bull. U. S. National Museum, 

 No. 22, p. 77, April 20, 1882) to occur in the neighborhood of Washing 

 ton: Q. album, G. virc/inianum, O. strictum, and G. vernum. The third 

 of these proves to have been incorrectly recorded, as the specimen la 

 beled Geum strictum in the Ward herbarium is unquestionably G. vir- 

 ginianum. Moreover, the locality where it was collected, Hunting- 

 Creek, Fairfax Co., Virginia, with which I am thoroughly familiar, is 

 not a place where the northern plant, if found in this region at all, 

 would be likely to occur. The number of species in the local flora will, 

 however, remain unchanged, as Geum flavum, though not hitherto re 

 corded, is common in Fairfax County. According to my observations, 

 during the past two summers, it seldom if ever grows in the damp, 

 heavily shaded locations often frequented by G. canadense, and never in 

 the half-boggy thickets preferred by G. virginianum, but usually occurs 

 in open dry woods. Gerrit S. Miller, Jr.
