I liaii I he (il lii'i': nor do I tiiid cNcn Nariclal dilfei'ences. Bentluinrs iiiiirrn- 

 phyUiis, on the other hand, seems likely to be at least a good variety. 

 Th(> leaves are much enlarji'ed and sinuate-lobed. If this merely occurred 

 here and therewith the type we nii,i;ht explain it as due perhaps to a 

 combination of shade and riclisoil: but on the conti"ir\' it has a some- 

 what self-consistent range which is far from identical with that of the 

 tyjx'. namely, from Oregon eastward through Nebraska and Miiniesota 

 t(i norlhcrn and central Michigan. There is also a Missouri specimen 

 thai seems to belong to this. Bentliam cites Pursh"s \ariety (/iirrrifolinx 

 as a synonym, of which the locality is given as the high mountains of 

 Virginia. As the National Herbarium contains no specimen from that 

 region, I can express no opinion concerning it. It is conceivable that 

 this plant of rather northern range is represented in the Allegheny Moun- 

 tains. howe\-er. If the two are found identical, the name <iii<rrifiiUux 

 woidd lake precedence of iiiticropfiiiUafi.

 Dr. \'asey near Chain liridge. The specific name doubtless refers to 

 the i)inkish color of the stem.

 *644h. Physalis Virginiana IMill. 



This species or one which 1 cannot distinguish from it sometimes 

 grows on very low ground, even in the river marsh. On the Potomac, 

 flats (August 8, 1896) stems a yard long, lying prostrate on the ground, 

 were observed. The ordinary form, above the railroad trestle beyond 

 (lievy Chase Bake, September B2, 1!)00. 

 *642a. Solanum Dulcamara B. 



Seen by me only as a dump plant along the river front in 189!). 

 *642b. Solanum pseudocapsicum B. 



A number of specimens of the Jerusalem cherry were found on the 

 margin of dumping grounds on New-cut Road, November IB 1900. 

 Some were in fruit, and there were a few flowers. The plant probably 

 escaped from the refuse of some greenhouse.
