Steele Additions to the Flora of Washington* 67 



225. Vicia tetrasperma (L.) Moench. 

 Takoma Park, 1896; Giesboro road, 1899. 



226. Vicia hirsuta (L.) Koch. 



Waste ground, Potomac flats; among the truck lands below Anacostia. 



224. Vicia saliva L. 



I have plants with narrow and with broad leaves; the latter are perhaps 

 distinct from V. anyustifolia Roth, but the separation is not easy. 



*22pa. Vigna Catjang L. 



Found occasionally on dumping grounds. 

 23 ia. Falcata Pitched (Torr. & Gray) Kuntze. 



Abundant in the river swamps; also occurs near streams back from 

 the river. 



2296. Dolichos Lablab L. 



Found on several occasions on dumping grounds. 



i53a. Oxalis corniculata L. 



Abundant on the Agricultural grounds not far from the building. 

 Collected with flowers and fruit December 4, 1900. 



1536. Oxalis filipes Small. 



Common. Blooms from May to the end of September, the stem grad 

 ually elongating and falling over, but not rooting. My specimens show 

 pretty clearly, however, that this plant develops some short, creeping 

 stems. 



153. Oxalis stricta L. 



Common. Begins blooming a little earlier than 0. fili-pe*, and seems 

 to finish mainly by the end of June, but it is found more or less in flower 

 throughout the summer, the stem elongating moderately. It forms lit 

 tle clumps of stems with a decumbent base which may be two or three 

 inches long. Besides the transverse ridges there are two well-defined 

 longitudinal ridges on the face of the seed and a groove on its margins. 



153''. Oxalis cymosa Small. 



Very common. Begins to blossom late in May and continues through 

 out the season, the stem elongating greatly. 



I53f/. Oxalis grandis Small. 

 Plummer's Island, June 22, 18j7. 



I44a. Linum medium (Planch.) Britlon. 



More abundant than L. \ r ir<jiuianuin, the species easily distinguish 

 able. The difference between these plants was clearly explained in 

 Ward's Flora. 



*99&. Polygala cruciata L. 



Brightwood swamp, August 16 and September 22, 1897. Also in the 

 Paint Branch swamps in some quantity, and at Lakeland. 



97. Polygala viridescens L. 



Flats opposite Alexandria, July 1, 1899. Only station found by me.
