owning the island. Since that time is has been often resorted to 

 by excursions, but whence came the Pky salts is a mystery. It grows 

 chiefly upon cleared spaces with Adlumia cirrhosa and Corydahs 

 aurea. In the ''Flora of North America" this species comes 

 under the heading '' Corolla pure white, * * wholly destitute of 

 any dark center," but in fact there are five ovate spots at the base of 

 the corolla, of a yellowish-green when the flower first opens, 

 but turning light yellow with age. These spots are perhaps a 

 fourth of an inch long and quite conspicuous, adding much to 

 the beauty of the flowers. The anthers do commonly show^ a 

 more or less evident *' tinge of violet/' but not always, many of 

 them being wholly yellow. It is probable that the absence of 

 any mention of the dark center in the corolla is due, as Watson 

 suggests, to the fact that the description of the plant in the " Flora 

 of North America" was taken from dried specimens in which 

 whatever color there was at first had faded. Still it is also possible 

 that our Vermont plants may exhibit this more strongly than 

 those from farther west. In my own dried specimens, thus far, 

 the yellow of the center is more, rather than less, evident than in 

 fresh specimens, although this may not be the case with those 

 long dried. G. H. PERKINS, University of Vermont. 



Hypnum [Thtndiuin) calyptratiim, Sulliv. — A mistake in the 

 locality given In '* Lesquereux and Jam^es* Manual " has been dis- 

 covered by Dr. Watson, which dates back to the publication 

 of Whipple's Report, p. 190. Instead of its having been found 



"near Los Angeles, Cal., on the ground" by Ur. Bigelow^ he 

 collected it "on rocks, Ben More, New Mexico, May, 185 1/' as 

 shown clearly by the specimens in the Sullivant collection.
