 PROCEEDINGS OF THE CLUB 



Meeting of October 26, 1921. 



The meeting of October 26, 1921, was held in the Museum of 

 The New York Botanical Garden. 



Mrs. Ruth H. Burritt, Yonkers, N. Y., and Miss Marie 

 Matacotta, Elmhurst, N. Y., were elected to membership. 



Dr. Arthur Hollick gave the "Notes on Introduced Plants of 

 Staten Island" published in this number of Torreya. 



Mrs. E. G. Britton spoke of "An African moss in Trinidad." 

 She exhibited specimens of Rhacopilopsis Pechuelii (C. M.) 

 Cardot from Africa and stated that no record exists of this 

 genus as occurring anywhere except in Africa. Specimens of 

 Ectropothecium trinitense (C. M.) Mitt, from Trinidad, collected 

 by Cruger, on Mount Tocuche, were shown to belong to the 

 genus Rhacopilopsis. Mrs. Britton stated that she had collected 

 Mitten's Ectropothecium trinitense last winter at Morne Bleu, 

 and had sent duplicates to Brotherus, who had confirmed her 

 determination. Monsieur Theriot had been kind enough to 

 send, in exchange, two specimens from French Guiana, which 

 vary only slightly from the Trinidad species. 



Dr. A. B. Stout spoke of "The Fringed Gentian at Pleasant- 

 ville. New York." It appears that about fifteen years ago Dr. 

 George F. Norton of Pleasantville, noting the absence or extreme 

 scarcity of the fringed gentian in that locality, scattered seeds 

 of it at several points, and that the plant is now moderately 

 abundant in several places. A quantity of the minute seeds, 

 recently collected, was exhibited and the form and peculiar 

 appendages of the seed were shown under a microscope. 



Under the title of "A rare Polytrichum in Oregon" Mr. R. 

 S. Williams discussed Polytrichum angustidens H. Lindb. This 

 species was first collected in Idaho by J. H. Sandberg in 1892, 

 and it passed as P. formosum until H. Lindberg recognized its 

 distinctive characters, the most important of which are found in 

 the superficial cells of the lamellae of the leaf costa. Specimens 

 obtained by J. C. Nelson, near Multnomah Falls, Oregon, 

 constitute the second known collection of this species. 



I )r. Marshall A. Howe remarked on "The Working of Long 

 Lake, New York Botanical Garden." The murkiness of the 

 waters of this pond during August and September appears to
