exceptionally large specimens, but we did not find it this time, probably 
because it was too late. Lonicera caerulea L. is a frequent shrub along 
the meadows. 
Our last collecting for the day was in Putnam, Conn., where we 
excited the distrust of the natives by groping successfully in the dusk 
of early nightfall for Vernonia noveboracensis Willd., and Liatris scar- 
iosa, Willd., conspicuous plants which we had located on the morning 
journey, and reserved for our homeward way. 
All in all, we considered the day a very successful and enjoyable 
one, and the region well worth further exploration. Most of the plants 
mentioned are represented by specimens in my collection or Mr. 
Spalding's, and although but few are distinctly rare, many of them 
belong in that larger class so well known to botanists as “interesting.” 
I am indebted to Mr. Walter Deane for kindly assistance in identi- 
fying the Myriophyllum and the Sparganium.

Four INTRODUCED PLANTS AT CAMBRIDGE, MASSACHUSETTS.— 
‘On 31 July of this year I noted, beneath a hedge-row along a street in 
Cambridge, a specimen of Neslia paniculata (L.) Desv., a crucifer 
with small, globose, indehiscent, reticulated silicles. The specimen 
was a small one but the distinctive fruit made it easily determinable. 
I have gathered it in better condition and greater abundance on docks 
at Quebec, 31 August, 1904. Thymus Serpyllum L. was found in 
abundance in a plot of grass land in Cambridge on 23 July of this 
year, and on 8 August another patch about a half-mile away, across 
the Charles River, near Soldiers’ Field in Brighton. On 8 August 
I came across a bush of Colutea arborescens L. escaped by a roadside 
near Mt. Auburn Cemetery. Epilobium hirsutum L. is well estab- 
lished near Glacialis Pond, Cambridge. Specimens of these plants 
are in my herbarium.— ARTHUR STANLEY PEASE, Cambridge, Massa-
