of the proposed handbook of North American grasses. The present paper 
includes nine such species. In the same publication Miss E, L. Ogden 
describes and figures the leaf structure of Jowveaand of Eragrostis obtustfiora. 
N. Rose and E. G. Baker.* In the collections of Messrs. E. W. Nelson and C. 
G, Pringle and Captain John Donnell-Smith two undescribed species were 
discovered, which, with an anomalous one described under Sida, are taken to 
constitute the new generic type. The genus is composed of five species, two 
of which are Mexican, one Central American, and two South American, but 
only three species appear in the present paper. The genus is dedicated to 
Dr. B. L. Robinson, Curator of the Gray Herbarium. Professor Sargent ¥ 
describes and figures Cladothamnus pyrolefolius, a woody ericaceous plant 
which grows in the upland meadows of Alaska. A second species, long con- 
founded with the Alaskan plant, inhabits Washington and British Columbia, 
and has been described by Professor Greene as C. campanulatus. The folio 
of Pittonia issued July 20% completes Part 16. Among descriptions of new 
species there are “corrections in nomenclature,” among which A/amosco is 
is made to replace Zephyranthes,; and a discussion of certain “ ranuncula- 
ceous monotypes,” Awmdlienia (R. hystriculus), Arcteranthis (R. Cooleye@), 
and Cyrtorhyncha (R. Nuttaliit). A new Antennaria from New England has 
been described by M. L. Fernald.3? Dr. Carl Miiller has just published 
descriptions of fifty new species of Jamaican mosses. In a recent number of 
Engler's Jahrdticher* the studies of African plants are continued, Schumann 
completing the Rubiacez, proposi four new genera (Probletostemon, 
diina, Thunbergianthus, Strigina); Pax makes his third contribution to the 
Euphorbiacee ; and Hennings presents a second paper on the fungi. In the 
same journal, of later date,4? Schumann discusses Phyllocactus and Epiphyl- 
lum; Urban presents a fourth fascicle of “Additions to the West Indian 
flora,” which consists of complete lists, with keys to the larger genera, of the 
great groups Loranthacez, and pceridophytes ; and Dietel and Niger publish 
a second contribution upon the Uredinee of Chili. Hans Hallier*? has begun 
a series of notes preparatory to a “ monograph of Convolvulacee,” the first 
paper being a discussion of nomenclature, and notes on various species.
