all genera and species. In Psilopilum there is a discussion of the two species 

 P. tschuctschicum and P. laevigatum with their varieties, Oligotrichum incurvum 

 var. latifolium Frye is reduced to a synonym of the former species; vars. hymeno- 

 carpum and aloma of P. tschuctschicum are described as new, both occurring in 

 Greenland and the latter also on St. Paul's Island. Oligotrichum incurvum 

 Frye (non Lindb.) is described as var. brevifolium Hagen under 0. incurvum 

 Lindb. Pogonatum alpinum is placed under Polytrichum; the remaining species 

 are P. polytrichoides (L.) Brockm., (P. nanum Beauv.); P. mnioides (Neck.) 

 Hagen (P. aloides Beauv.); P. dentatum var. minus (Wahl.) Hagen; and P. ur- 

 nigerum Beauv. A very complete account is given of P. dentatum var. minus, 

 which is considered as synonymous with P. longidens Aongs. and Polytrichum 

 Wahlenbergii Kindb. Attention should also be called to a new variety of Poly- 

 ticum alpinum, var. propinquum Hagen, from Melville Island, and to the ex- 

 tended account of Polytrichum Jensenii Hagen. P. inconstans is considered a 

 synonym of P. Swarzii var. nigrescens (Warnst.) Hagen.

Members of the Sullivant Moss Society will learn with sorrow of the death 

 on September i8th last of Miss Jane Wheeler, of Albany, N. Y., for more than 

 twelve years a member of the Society and keenly interested in its work. She 

 was a lover of outdoor life and of all that is included in that term. Her summers 

 were usually spent in the open country or at the seashore, and she had an intimate 

 and exact knowledge of birds, trees, flowers, ferns, seaweeds, and mosses, which 

 gave her great delight and satisfaction, making her an authority among those 

 less well informed and observant. Under the shade of the graceful elms at 

 Maiden's Bridge, where she had spent many summers, she passed away as gently 

 as she had always lived. She was a woman of rare fineness of spirit and mind. 

 An invalid for many years, her ill health stood in the way of much that she 

 would otherwise have done gladly and efficiently.
