Some Maine plants.— A residence of two months duiing the past sum- 
mer in Dennysville, Me., very near the “jumping-off place,” known as 
Sail Rock, the most eastern extremity of the United States, and sundry 
excursions botanical and piscatorial along the coast for fifty miles or more, 
brought to light a few botanical facts of interest. 
Euphrasia officinalis, previously collected on the Plains of Abraham, 
near Quebec, of very dense, compact habit, here occurs in great abund- 
ance, so as to be quite conspicuous along the roadsides, and even over 
the pastures, but loose and branching. It is not found farther inland 
than twenty miles, but extends along the coast as far as Marchion. 
Rubus Chamemorus, the cloud-berry, knowh among the natives as 
“baked-apple,’ occurs in sphagnous swamps in such quantities as to be 
brought to the stores for sale, though not very attractive to most of us. 
Mr. Kennan says that the Siberian variety is much more palatable. I 
had hitherto seen this only on some of the summits of the White Mount- 
ains. 
Empetrum nigrum occurs also abundantly in company with the last. 
Rhinanthus Crista-Galli is a troublesome weed in the fields and pas- 
tures within a few miles of the coast, its inflated seed-vessel rendering it 
quite conspicuous in fruit. 
i ritima is found sparingly along the sandy borders of sea- 
beaches, and has been noted as far west as York, Me.—J. W. CHICKERING,

An erratum.—In the record of Dr. Gray’s careful determinations of 
the Gamopetalz of Dr. Palmer's Jalisco plants, included in my “Contri- _ 
bution xiv” (Proc. Amer. Acad. xxii), there occurs a single error which 
Idesire to correct. On page 432, under Cacalia tussilaginoides, the “ ex 
char.” should be erased, leaving the determination, as Dr. Gray intended 
it to be, “Cacalia tussilaginoides, HBK. Nov. Gen. & Spec. 4.168?” The 
first reading was as given after his examination of the material in the Kew 
Herbarium, where he found Coulter’s Zimapan specimen, to which he re- 
fers as intermediate between Palmer's and the original plant as described 
by Humboldt and Bonpland. In Paris he found the very specimen upon 
Which the species was founded, but this left him still in doubt as to the iden- 
tity of Palmer's plant with it, In consideration, however, of the deciduous 
_ character of tomentum generally (which in this case is, as described, thin 
and rather scanty—“folia subtus tenuiter cano-tomentosa ”) and the ten- 
wad of the foliage in Cacalia to vary, he deemed it prudent to let his Kew 
etermination stand, and ended his note to me with, “Just print _ : 
name with an?.” In correcting the proofs in accordance with his lates 
conclusions I neglected to dele the “ex char.” as I should have done-—
