and Ulothrix, noted as " On pine logs coming down the river " when 

 the ship was at some Florida port. 



For new stations, we may note Gobia Baltica (Gobi) Reinke, at 

 Louisburg, N. S. ; heretofore known in America only by a single 

 finding at Newport, R. I. Choreocolax Polys iphoniae, Reinsch, from 

 Nova Scotia, Maine being the former northern limit. Dermocarpa 

 prasina (Reinsch) Born. & Flah., at Sydney, former northern limit, 

 Maine. Sphacelaria cirrhosa (Roth) Ag., St. Lawrence River; with 

 the exception of the warm-water colony at Quahaug Bay, Maine, not 

 before reported north of Gloucester, Mass. Dictyosiphoti focmcu- 

 laceus, forma flaccidus, Kjellm., from Newfoundland ; a form extend- 

 ing from the north of Europe to Greenland, but not on record farther 

 south on this coast. Mesogloia divaricata (Ag.) J. Ag., Newfound- 

 land, not reported north of Maine. Ulva fasciata, Delile, Norfolk, 

 Va., Florida being hitherto the northern limit. 



The few species from Progreso, Mexico, are very tantalizing. 

 Almost nothing is known of the algae of the Gulf coast of Mexico. 

 Murray, in his Catalogue of the Marine Algae of the W. I. Region, 

 after noting the rich flora of Florida, says, "The whole coast of the 

 Gulf of Mexico has been ascertained to be barren," but here are 

 very luxuriant specimens of Caukrpa prolifera (Forsk.) Lamour., 

 Codium tomentostnn (Huds.) Stack., Bryothatntiion Seaforthii (Turn.) 

 Kuetz., and Euchcuma isifortne (Ag.) J. Ag. Where these were 

 found, it is more than likely that forms usually found with them else- 

 where should also occur; and while we are grateful to Mr. Moe for 

 so much, we can only wish we had been there with him. 



The collection includes about seventy species, and it is now depos- 

 ited in the herbarium of the Botanical Museum at Christiania, Nor- 

 way. May the example find many followers.

AN UNDESCRIBED VARIETY OF GOLDENROD. 



C. B. Graves. 



In the summer of 1892 I found in one of the swamps of Waterford, 

 Connecticut, a form of Solidago that was new to me. Notwithstand- 

 ing that it grew in a decidedly wet situation I was lead to think, on
