proves correct. The plants were collected along a ditch near 

 California, Washington County, Pa. It has not been formerly 

 reported from this state, and possibly this marks the northeastern 

 limit of this plant. 



The range for this plant is given in Gray's Manual, Ohio to 

 Illinois, south to Florida and Texas ; in Britton and Brown's 

 Illustrated Flora, Virginia to Florida, west to Illinois, Missouri, 

 Texas and Mexico; in Small's Flora of the Southeastern U. S., 

 Virginia to Illinois, Missouri, Florida, Texas and Mexico. 



Cycloporus Greenei. Mr. and Mrs. O. E. Jennings, of the 

 Carnegie Museum, collected some fungi at Ohiopyle, Pa., during 

 the month of September, 1906, and in the collection was an ex- 

 cellent specimen of Cycloporus Greenei (Berk.) Murrill. Only 

 one plant was found. This is the first report of its occurrence in 

 Pennsylvania. Dr. Murrill reports it from the following states : 

 Massachusetts, New York, Connecticut, New Jersey, Iowa, West 

 Virginia, Vermont. (Bull. Torrey Club 31 : 423. 1904.)

Note upon a Guam Species of Ipomoea. — In Safford's " Use- 

 ful Plants of Guam," Contr. U. S. Nat. Herb., volume 9, Mr. W. 

 F. Wight proposes a new name, Ipomoea CJwisiana for /. dentic- 

 nlata (Desr.) Choisy (1833), not R. Br. (1810). It would seem 

 strange if one who has written as much regarding the Convolvu- 

 laceae as has Choisy, should not already have had some species 

 in the group named for him, and we find several, two of them in 

 Ipomoea, viz : 



Ipojnoea Choisyi Montr. Mem. Acad. Lyon 10 : 237. i860. 



Ipomoea Choisyana Hallier f. Bot. Jahrb. 18: 130. 1894. 



The species which Mr. Wight renames has other names prior 

 to that taken up by Choisy in Ipomoea. Robert Brown described 

 it as /. gracilis (Prodr. 484. 18 10), and as there appears to be 

 no earlier use of that name in Ipomoea, it will stand for that 

 species.
