red fibrous bark; bark of the branches flaking off in thin plates and 

 leaving a smooth surface ; branchlets stout and rather rigid, sharply 

 quadrangular; leaves closely imbricated, very glaucous, neither pitted 

 nor glandular; their margins entire, or, in the very oldest, denticulate; 

 cones crowded on short, stout peduncles, globose, about an inch in 

 diameter, of 6-8 very thick, and strongly bossed scales ; seeds 

 numerous, 2 lines or more wide. 



This fine cypress was discovered by the \\;riter on the mountains 

 back of Clifton, in the extreme eastern part of Arizona, on the first 

 day of September, 1880. 



Abundant specimens of wood, and fruiting branches were secured, 

 and soon distributed, under the above name, to the principal herbaria 

 of this country, and several in Europe, including that of the Royal 

 Gardens at Kew. 



In the course of the year and a half that has since intervened, 

 the species has been collected at different points in the southern and 

 eastern portions of the same Territory, by Messrs. Rusby, Pringle and 

 Lemmon. The tree is peculiar in that, while the bark of its trunk is 

 as shreddy as that of any cedar, that of the branches, even the larger 

 ones, is scaly, falling off in thin plates. The wood is light and 

 straight grained, splitting with the utmost readiness; that of the 

 heart being dark red, resembling that of red cedar. The branchlets 

 bear so strong a likeness to those oi Junipenis pachypJdoea^ Torn, that 

 without fruit they are hardly distinguishable. It is the principal 

 tree of the mountains which lie to the north of Mt. Graham, and 

 forms dense forests, particularly on the northward slopes,

Notes on New England Algae. 



By W. G. Farlow. 



Since the appearance of my paper on New England Algae, I have 

 received a number of interesting species, new to our coast, from 

 Mr. F. S. Collins of Maiden, Mass., and Rev. J. D. King, of 

 Edgartown, Martha's Vineyard. In 1881 Mr. Collins sent a speci- 

 men, collected near Little Nahant, which resembled a small Aspero- 

 coccus, and which could not at the time be determined. In March 

 of this year he succeeded in finding a considerable number of spec- 

 imens of the same species in excellent condition, and, through his 

 kindness, I have been enabled to examine both living and dried 

 specimens. The alga in question is of a decided olive-brown color 

 when fresh, and becomes somewhat greenish in pressing, in this re- 

 spect resembling some of the Asperococci and Punctariae. The 

 frond is tubular, and resembles strongly the species of Asperococcus in 

 habit, .but even in its adult condition it is composed of a single layer 

 of cells, which are generally associated in fours and are of a gelatinous 

 texture. Were it not for the distinctly brown color, one would be 

 inclined to consider the plant as a species of Prasiola, especially if 

 examined after having been dried. There can be no doubt, however, 

 that it belongs to thePhaeosporeae, and it appears to me to constitute 

 a new genus {Phaeosaccion) of that suborder, differing from other 

 genera in having its tubular frond composed of a single layer of rather
