 held in Washington, D. C, November 16 to 19, 1900, and which has been previously

BOTANY. 



Grasses — I, L. H. Pammel, J. B. Weems, and F. Lamson-Scribner {loiva Sta. 

 Bui. 54, pp. 71-344, fig.^. 137). — Original observations and compiled notes are given 

 relating to the general description of grasses; the growth and minute structure of 

 their roots, stems, leaves, and flowers; a discussion of fertilization and hybrids; and 

 the various phenomena attending germination. Chapters are devoted to cereals in 

 which the more important ones are described, and their production, climatology, 

 and uses as medicines are indicated. Various sugar-producing grasses are enumerated 

 and other economic uses described. The poisonous and injurious effects of certain 

 grasses are mentioned, and notes given on the fungus diseases to which grasses in 

 general are subject. 



Our native pasture plants, ¥. Lamson-Scribner ( U. S. Dept. Agr. Yearbook 1900, 

 pp. 581-598, ph. 4, figs. ll). — Descriptions are given of many of our more important 

 native pasture grasses, the author having grouped them under the heads of grasses of 

 wooded regions, mountain meadows, and deer parks, treeless regions, and pasture 

 plants of alkali soils. 



Some Arizona grasses, E. D. Merrill ( U. S. Dep>f. Agr., Division of Agrostology 

 Circ. 32, pp. 10) . — Critical notes and descriptions of new species and varieties of grasses 

 collected by P. Griffiths and R. H. Forbes, of the Arizona Station, are given. 



Aristida purpurea and its allies, E. D. Merrill ( U. S. Dept. Agr., Division of 

 Agrostology Circ. 34, pp. S) . — Critical notes and technical descriptions are given of 

 Aristida pwpivrea and the allied species which occur in North America. 



Oil-yielding plants cultivated in Egypt, G. Bonaparte {.Tour. Khediv. Agr. 

 Soc. avd Srlinol Agr., 3 {1901) , No. 1, pp. 14-19). — The plants cultivated in Egypt for 

 the production of oil are said to be flax, sesame, cotton, safflower, and lettuce. The 

 methods of extraction and character and uses of the oils, as well as the use of the 

 by-products, are described. 



The geology and botany of the Tipper Peninsula Experiment Station, C. F. 

 WiiEELKR {Michigan Sfa. Bui. 186, pp. 17-27). — Notes are given upon the geology of 

 the substation located at Chatham in the northern peninsula of Michigan, and lists 

 and critical notes are given upon the trees, shrubs, and herbaceous plants growing at 

 the station grounds. A list is also given of a number of fungi which were observed 

 causing diseases of cultivated plants at the substation. 



Descriptions and illustrations of new species of Micromycetes, F. Tassi 

 {Bid. Lab. Orto Bot. B. Univ. Siena, 3 {1900), Xo. 3-4, pp. 117-132, p>ls. ^).— Descrip- 

 tions are given of about 50 species of Micromycetes which have not hitherto been 

 described. Many of them occur on dead or decaying plants, although a few were 

 found to be parasitic on the leaves of living plants. Among the latter class may be 

 mentioned PhyUosticla yulan, which is found parasitic on the leaves of Magnolia yidan; 

 P. edivardsiw, on the Edwardsia microplnjlla; P. salisburiiv, parasitic on the leaves of 

 the common Gingko biloba; Phoma btdbicola, on bulbs of Freesia; Ascochyta catalp.v, 

 on the leaves of Catalpia speciosa; Bartalinia nervisequa, on the leaves of Magnolia 

 grandiflora; Glceosporium coffeicolum, on the leaves of Coffea arabica; and Pestalozzina 

 Celestri, parasitic on the leaves of Celastrua bu.rifolia.
