Nos. give some account of the Flora of Martha’s Vineyard and vicin- 
ity, by Rev. Thomas Morong; the March No., Addenda to the Flora 
Columbiana, 1084-1142. Mr. Ward has found Polypodium vulgare 
growing on the living bark of Betula nigra, several feet above the 
base, after the manner of P. tmcanum. 2. The Botanical Gazette for 
February and March concludes Dr. Chapman’s long list of new South- 
ern (chiefly South Florida) plants. Dr. Vasey describes Poa Lem- 
mont, a new species from Sierra Co., Cal. Mr. Bebb finds that Sa/ix 
cordata, var., glaucophylla of Babcock’s Chicago catalogue, corres- 
ponds so closely with §. Barclay7, And., that either the latter should 
be reduced to S. cordata, or the former to S. Barclayi, var. grandt- 
folia, 5. Barclayi was found by Kellogg in Alaska. Mr. J. Wolf 
gives a list of 61 Lichens of Southern Illinois. Several writers dis- 
cuss the question “ Whence the seeds ”’ of plants that seem to spring 
up spontaneously in new clearings Mr. Lemmon writes on the 
Flora of the Great Basin. In the April No.; among many interest- 
ing notes, including ,Bryological by Mr. Austin, and Mycological 
(new Colorado Fungi) by Mr. Peck, we find Mr. Curtiss recording 
Mistletoe parasitic on itself, and Dr. Rothrock recommending a con- 
venient dissecting microscope, made by Zentmeyer, of Philadel- 
phia, for fifteen dollars, or sixteen dollars with an extralens. In the 
May No., Dr. Gray accepts Mr. A. Common’s description of two 
forms of the common Plantain; P. Afajor, L., the smaller obtuse 
form ; P. Rugelii, Decaisne, the larger acute form, with leaves gen- 
erally smooth; spikes longer, tapering to a point, pods longer and 
larger, opening below the middle, seeds larger, black, not wrinkled, 
sepals decidedly narrower, and more strongly keeled. Mr. Mohr 
gives a list of foreign plants introduced into the Gulf States. In the 
June No., Prof. Wood gives an interesting list of Indian Territory 
plants, some of which are new. Prof. Porter records the seed of 
_ Datura Tatula coming up for ten years after the parent had been 
extirpated. Mr. Davenport finds polygamous flowers in Populus. 
Dr. Kunze scouts the idea of Monotropa’s being poisonous to the 
touch, and suggests, as is probable, that the poisoning was due to 
root fibres of Rhus Toxicodendron. Mr. Broadhead writes on the 
distribution of certain plants in Missouri. ‘Truly a Botanical 
Gazette. 3. The American Naturalist, for March, publishes an essay 
by Dr. J. M. Anders on the transpiration of plants. This was a 
prize medical essay, and is not only of value in itself for careful. 
research in a field not yet well explored, but in giving evidence of 
’ advance in the aims of our educational institutions. The “ Rambles 
of a Botanist’’ (Mr. Greene) in New Mexico, will attract alike by 
their matter and their manner. A. W. Bennett gives an account of 
M. Rodier’s discovery of a rhythmical movement in Ceratophyllum 
demersum, which we may all observe this Summer for ourselves ; 
for what water plant more common than Ceratophyllum, what 
apparatus so ready as a glass of water? Choosing a branch with 
the intermodes elongated and the whorls distant, and the leaves
