212 Rhodora [OCTOBER 
persisted through the winter). No one else gathered any and the 
station was not visited by any one until I took Mr. Jay G. Underwood 
there this last June and collected a lot of material. The plant grows 
at least four miles from the male fern station which is found in the 
highlands of the town.” 
The strobiles are full-grown, the running stems evidently did not 
lie on the surface of the ground, and the annual growths of the fork- 
ings are very plainly marked. The Hartland and Caribou plants are 
well matched by many specimens in the Gray Herbarium, and I 
surmise will prove to be typical of the form of the species in its south- 
ern range, but the cover there containing the specimens of L. compla- 
natum in fact holds in addition to these a variety of diverse forms 
which make it evident that much collecting is needed. It is plainly 
a polymorphous species as at present known, but whether its forms 
are distinct and wide-spread, or are intergrading and local, we have 
no means of knowing at present. The untiring fern hunters can here 
find a promising field for investigation. 
The interesting finds in the neighborhood of Hartland lead one to 
wonder whether that section has a really rare flora, or are these simply 
the outcome of an active nature club which may be equalled in many 
places if a similar effort were made?

DRACOCEPHALUM THYMIFLORUM A CASUAL PLANT AT WESTFORD, 
MASSACHUSETTS.— Late in June, 1911, I visited a wool-waste dump 
on one of the farms in Westford, Mass. Among the weeds found 
there was a mint, identified for me at the Gray Herbarium, as follows: 
“Dracocephalum thymiflorum L., a native of northeastern Europe 
and Siberia and according to recent floras becoming introduced in 
central Europe. We have no American specimens of this species, 
nor do we find any record of its occurrence in the United States.” —
