During each of the three years I have found the so-called var. 
obttisilobata of Onoclea sensibilis growing in the same locality under 
conditions identical with those noted by me in this journal for Sep- 
tember, i88r, I am more fully convinced that the explanation there 
given was sufficient to account for the variation in this locality. . 
I have also the pleasure of recording "Tamarack Swamp," near 
Syracuse, N. Y., as a new locality for Botrychiiim simplex. Hitch.

The Involucre in Malvaceae. 
W 
statement in the Bulletin for December, 1883, that a .greenhouse 
specimen of Abutilon had been found with traces of an involucre, I 
am happy to be able to say that a 3-leaved involucre is normally 
present in the young flowers of the common velvet-leaf {^A. Avicennce) 
and also in the greenhouse species, A. vexillarium (one of the bract- 
lets -long, the others short.) These facts, taken along with the pres- 
ence generally of a hypocalycine node in the 'non-involucrate' Mal- 
vaceae, suggest that the distinction between them and their involu- 
crate allies is unwarranted, the real distinction being that in some the 
involucre is fugacious. In some of the genera there are difficulties 
in the way of verifying this view, arising chiefly from the bristly 
character of the young flower-buds.

Notes from Massachusetts. — At one of the field meetings of the 
Essex Institute, held at Groveland, Mass., several plants were re- 
ported as having appeared there, the seeds doubtless having been m- 
troduced from the West in wool or in grain and other seeds. Oi 
those mentioned there were Linnm usitatissimiim^ Pentsiemon DigttaiiSf 
Ly thrum alatum and Verbascum Blaltaria. The same Pentstemon 
* W, Ilvensis can hardly be ranked here, as 1 found it near Sage's Ravine not 
more than one-eighth of a mile over the Massachusetts line. It is doubtless found 
on the brows of the same range of hills extending southward into Litchfield To.
