very numerous, about 18-flowered ; involucre campanulate at the base ; 
bracts purplish tinged, the outer short, ovate, acutish, the inner lance- 
oblong, obtuse, 8 to 10 mm. long; corollas blue; pappus in the fresh 
plant pure white, in dried specimens with slight cream tint: achenes 
lanceolate, black, mottled with patches of brown in the manner of tor- 
toise-shell, rather broadly margined and distinctly 3-ribbed on each 
face, 4 to 5 mm. long, exclusive of the short green filiform beak (1 mm. 
in length). — Collected on a reclaimed salt marsh at Marshfield, Mass., 
by Charles H. Morss, Aug. 14, 1898. Type in Herb. Gray. 
In many respects this species shares the characters of Z. leucophaea 
and Z. canadensis, but its broad, thickly-set conspicuously cordate- 
clasping rather bluntly lobed leaves differ considerably from the ordi- 
nary northern forms of these species. Furthermore, the occurrence 
of natural hybrids between species of such dissimilar fruit-characters 
seems unlikely. Several specimens of Z. Morssii were observed, and 
al maintained their characters with constancy; the achenes, seeds, 
and embryos were so perfectly developed as to leave little doubt of 
their fertility ; and under these circumstances the writer does not feel 
warranted in resorting to an unsupported hypothesis of hybridity to 
account for the origin of this well-marked type. 
It is highly improbable that Z. Morssii is restricted to its Marshfield 
locality, and it is hoped that every reader, who has an herbarium of 
New England and Middle State plants, will examine his specimens of 
Lactuca, especially of Z. lencophaea and L. canadensis, and see whether 
some of them may not prove to be of this new and interesting species, 
which may be readily recognized from the above characterization and 
the accompanying plate, kindly prepared by Mr. F. Schuyler Mathews.

COMPARATIVELY speaking, the flowering plants of the New England 
States, and even their ferns and mosses, are well known. Yet, as an 
article in this journal shows, the discovery of novelties is still quite 
possible. If this can be said of the higher plants, it is still more con- 
spicuously true of the lower forms.
