Rteele Additions to the Flora of Washington. 01 



Captain Jones' place near Chevy Chase Lake. Also on a brook above the 

 Dalecarlia reservoir remote from dwelling's. 

 *8o7. Humulus Japonicus Sieb. 



Waste ground, September 30, 1899, pistillate flowers. 

 8 1 6. Parietaria Pennsylvania Muhl. 



High Island and slope above Canal road. 

 *y87. Asarum reflexum ambiguum Bicknell. 



Moist woods, different places near District line on Cabin John R. R., 

 May 28, 1901. 

 781. Rumex verticillatus L. 



Flats above Aqueduct Bridge, Virginia side, June 2, 1890. 

 *78o. Rumex Patientia L. 



Dump ground, June 5, 1901. 

 778. Polygonum scandens L. 



While some of our specimens have the calyx wings somewhat in 

 dented, the great mass of our material certainly belongs to this species. 

 I note in some specimens fruits that are almost wingless mixed with the 

 others. I have one collection which may prove to be P. crutatum. 

 752a. Chenopodium album viride (L.) Moq.f 



Not uncommon in waste grounds. 

 753- Chenopodium Boscianum Moq. 



Woods, Brick Haven, Ya., September 3, 1897; first noticed here by 

 Mr. L. H. Dewey. 

 755. Chenopodium murale L. 



Found several times in waste places around the city, also at First lock. 

 Rather common at Harper's Ferry. 

 *758a. Chenopodium rubrum L. 



Potomac flats, October 9, 1897; abundant. 

 758. Chenopodium anthelminticum L. 



I have found only a single specimen belonging to this species. Mr. 

 Dewey also found one on the experiment grounds of the Department of 

 Agriculture. The absence of bracts from most of the racemes, as well 

 as the greater length of the latter, are essential characters. 

 "749(i. Amaranthus blitoides S. Wats. 



Waste grounds, river front near Fourteenth street, September 20, 1897. 

 749. Amaranthus graecizans L. (.1. albu* of Ward's Flora.) 



Waste places in and around the city. Seen abundantly in a garden in 

 Suitland. 

 *75ia. Acnida tamariscina (Xutt.) Wood. 



I collected in 1897 or 1898 one or two specimens of this species on the 

 Potomac flats dumping ground. 



\Chenopodium botrys L. was collected at Harper's Ferry in September, 

 1900, but I have not yet found it within our limits.
