The other plant which I found 1923-1930 is Ononis rcpens L. 

 It was trailing on an empty sandy lot in eastern Bronx, in the 

 vicinity of Westchester Avenue. The single pink flowers at the axils 

 of the leaves are typical of the Papilionaceae, the ten stamens are 

 monodalphous ; the leaves are small, single, egg-shaped and finely 

 toothed. 



In his Botanico-geographical review, N. Kaufman, Professor 

 of Botany in University of Kiev, Russia, says that plants like 

 Ononis are not easily spread, as their fruit is a one-seeded legume ; 

 the seeds are few and too heavy to spread, and they have no adapta- 

 tions for dispersal. In its own habitat, eastern Europe, Ononis is 

 not plentiful. These new plants were seen by the late Dr. John K. 

 Small and more recently by Mr. E. J. Alexander.

Some Uncommon Adventives in Berks Co., Pennsylvania 



Hans Wilkens 



Eiilalia viminea (Trin.) Kuntze. Very abundant for a distance 

 of about a mile on both sides of the road following Wyomissing 

 Creek, in Wyomissing, a suburb of Reading. It was first noticed 

 in 1938, but must have been established for some time, to judge by 

 the area covered. Unlike the form of this species found in Tennessee 

 this has awned spikelets. 



Digitaria sanguinalis (L.) Scop., var. ciliaris (Retz.) Pari. 

 A form of crab-grass with the sterile lemma fringed with stiff 

 spreading bristles. Along the railroad tracks in Fleetwood, north- 

 east of Reading. First noticed in 1931, it has persisted, but not 

 spread much. The same form was collected along railroad tracks 

 in Washington, D. C, in 1937, and. no doubt, grows in similar 

 situations elsewhere. 



Thlaspi perjoliatmn L. Found in two places, north and north- 

 east of Reading, in 1935. No new colonies have been seen since. 



Eriicastrimi galUcum (Willd.) O. E. Schulz. Found on a steep 

 Imnk along a recently im])roved road near Centerport, northwest
