thrives equally, but is hardly as desirable: 7. erythrocarpum is very 
difficult to keep alive in a garden. I. H. Haut. 
49, Viola pedata, L.; “var. alba.”—I have in years past often found 
this variety in Connecticut, in several places in New Haven and 
Litchfield counties, and particularly along the line of the New Haven 
and Northampton R. R. My friend, Rev. Prof. J. A. Paine, Jr., m- 
forms me that he has repeatedly found it in Oneida County, north 
of Rome, also near Schenectady, and in Massachusetts, and else- 
where frequently. The Long Island locality is on the Coney Island 
(horse-car) railway, about three quarters of an hour from the Ful- 
ton Ferry, and was discovered by Miss Emma Beach of Brooklyn. 
In the same place grow several other varieties, viz. the “var. bico-_ 
lor,” others with petals streaked and spotted, and others with such 
pencilled markings as are frequent on the flowers of the common 
Y. tricolor of the gardens. 
As to the “var. tricolor,” I have found it almost everywhere 
where the V. pedata grows at all, and by no means very “sparingly. 
I am inclined to think that neither this nor the other varieties have ~ 
enough permanence to deserve a special name. I. H. H. 
50. New Immigrants —It is probable that many foreign weeds may 
yet secure a foothold on our soil; their arrival and fortune deserve 
to be watched. Last summer it was observed that Crepis virens, 
L. var. diffusa, had taken possession of the grassy banks in Green- 
wood Cemetery, though it had not apparently spread beyond. 
The summer before, I noticed a well grown plant of Sisymbrium 
Alliaria, Koch, in the main street of Flatbush village, so flourishing 
that there seemed no reason why it should not spread. This sum- 
mer, Mr. Ruger finds quite a growth of them in the ditches neat 
the rail-road station. Ww. HG 
51, Lepidium intermedinm, Gray.—This western species has not 
yet been detected here, but it so closely resembles L. Virginicum 
that it may be overlooked if it arrives. I have lately re 
ceived a good specimen from Texas, and find the pods rather 
broader than long, with the ears at top not so strongly marked 
as in the latter. The embryo more resembles that of L. ruderale, 
but with a longer cleft in the lower half. L. Virginicum has pods 
rather longer that broad; L. ruderale likewise, but only about 
half the size of the other two. W.- Be de

Pond, L. L About thirty plants were observed. M. Rucer. 
58. Seedling Locusts—There are several young locusts that have 
sprung from seed on our place, and I have noticed others in the 
neighborhood that must have originated in the same manner. | 
have to dig up many locust seedlings from my flower bed. :

in our last list of this plant, which is common enough on New York
