American Academy a list of the Marine Algi3e of the United States, 

 with notes of new and imperfectly known species. The eastern coast 

 has a very limited marine flora, but Key West is curiously rich in 

 species, *' The flora of that region is peculiarly West Indian, and has 

 little in common with the rest of the United States. "We are almost 

 in complete ignorance of the Algae on the coast of the States 

 bordering on the Gulf of Mexico. The Pacific coast far exceeds the 

 Eastern in the richness of its flora, and future additions to our Algae 

 will come from this region." The author enumerates 430 species, in- 

 cluding five or six new ones. 



A conspectus of the N. American Hydrophyllace<3, from the prac- 

 tised hand of Dr. A. Gray, appears in the Proceedings of the American 

 Academy, with the date April, 1875. We find 13 genera, under the 

 four tribes of HydrophyllecB, Phacelie(B, Namece, and Hydrolece ; and 

 93 species, more than half of which are placed in Phacelia, in which 

 genus are merged Eutoca, Cosmanthus, and Microgenetes. 



Under the title of *' Flora dell' Alto Serchio e del Lima " (1874), 

 a useful catalogue of the flowering plants and ferns of the neighbour- 

 hood of Lucca has been printed by Mr. Archbold and Dr. Carina. It 

 forms a thin pamphlet of 80 pages, and contains definite localities and 

 months of flowering of the plants of this rich district. 



A short notice of the medicinal products of the Indian Simarubea 

 and Purseracece, by Mr. A. W. Bennett, who worked up the orders for 

 the new "Flora of India," is printed in the Bartholomew's Hospital 

 Reports. The author has rather gone out of his way in speaking of 

 Myrrh and Manila Elemi, and the statements that the former is pro- 

 duced by Balsamodendron Ehrenhergianum, Bg., and the latter by 

 Canarium commune, L., are too absolute. The source of neither drug 

 is as yet satisfactorily known. 



We are indebted to Prof. Lange, of Copenhagen, for a copy of his 

 lately-printed Guide to the new Botanic Garden of the University. 

 The old historic garden was situate in the centre of the city, and it 

 was found necessary a few years ago to commence a new one in a 

 more open position beyond the town, and this was opened to the 

 public last year. The Guide, which is naturally written in Danish, 

 extends to 124 pages, and contains short accounts of the different 

 parts of the establishment, with notes on the more interesting species, 

 being illustrated with a large map which shows the position of the 

 principal plants. A novel feature in the arrangement of the hardy 

 herbaceous plants is the distribution of the beds devoted to the natural 

 orders over the entire garden instead of having them placed in sys- 

 tematic j uxtaposition. The general arrangement of the grounds is 

 not unlike that of the Royal Botanic Society's beautiful garden in the 

 Regent's Park. 



Mr. Yan Voorst has just published for Mr. Newman a fifth, or 

 people's edition of his well-known '* History of British Ferns." It 

 is a neat volume of about 200 pages, bound in green cloth, of a size 

 convenient for the pocket, and contains a description of each species, a 

 summary of its distribution, and full particulars for its cultivation. 

 There are six plates, which include reduced figures of all but a few of 

 the largest kinds.
