than the other; nor do I find even varietal differences. Bentham's macro- 

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

 The leaves are much enlarged and sinuate-lobed. If this merely occurred 

 here and there with the type we might explain it as due perhaps to a 

 combination of shade and rich soil: but on the contrary it has a some 

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

 type, namely, from Oregon eastward through Nebraska and Minnesota 

 to northern and central Michigan. There is also a Missouri specimen 

 that seems to belong to this. Bentham cites Pursh's variety quercifolius 

 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, however. If the two are found identical, the name quercifolius 

 would take precedence of macrophyttu*. 

 708. Lycopus rubellus Moench. 



River swamp, foot of First street, southeast, September 21, 1890; Hunt 

 ing Creek and Eastern Branch swamp at M street extended, September, 



1899. There is also a specimen in the National Herbarium collected by 

 Dr. Vasey near Chain Bridge. The specific name doubtless refers to 

 the pinkish color of the stem.

Virginia shore of the Potomac above Aqueduct Bridge, September 29

705 Mentha Piperita L. 



"The Point" at Jackson City, and on the Canal road; not abundant in 

 either locality. 

 *7o6. Mentha rotundifolla (L.) Huds. 



Cultivated ground in front of the Agricultural building, 1900. 

 *644a. Physalis ixocarpa Brot. 



Neglected ground near dwellings, water front at foot of Fifteenth 

 street, September BO, 1899. It fruited abundantly and appeared again 

 in 1900. 

 "6446. Physalis Virginiana Mill. 



This species or one which I cannot distinguish from it sometimes 

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

 flats (August 8, 189(5) stems a yard long, lying prostrate on the ground, 

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

 Chevy Chase Lake, September 12, 1900. 

 *642a. Solarium Dulcamara L. 



Seen by me only as a dump plant along the river front in 1899. 

 *6426. Solanum pseudocapsicum L. 



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

 margin of dumping grounds on New-cut Road, November 11, 1900. 

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

 escaped from the refuse of some greenhouse,
