on the under side of the leaf absorbed water more rapidly than’ 
those on the spaces between. 
The essay concludes with a critical comparison of the sto- 
mata of plants that are hairy, and emphasis is laid on the follow- 
ing deduction: ‘ Whenever the hairs or scales form a covering 
so that a protected layer of air exists between the covering and 
the epidermis, the stomata are raised, and where the outside air 
has free communication with the stomata, they are not raised.” 
Flora Braziliensis. Fascicle-xcvii of this stupendous work 
was issued on April Ist. It contains monographs of the Brazil- 
ian Ternstroemiacee by H. Wawra Eques de Fernsee, with 17

Dichapetalee by H. Baillon with 4 plates. 
Cooke's Illustrations of British Fungt. Parts Nos. 42 and 43 
of this fine work, commencing Vol. v., have recently been issued. 
The genus Agaricus is still the subject of illustration, the number 
of plates having nearly reached 700; the descriptive text is pub- 
lished in “ Grevillea”; the number of species of British Agarics 
described has now reached 577, as shown by the part issued in ’ 
the September number of that journal. 
Baillon’s Dictionnaire de Botanique. The 19th and 2oth 
parts of this work, completing Volume ii., have recently been 
issued, the last genus noted being Gytonanthus. A beautifully 
colored plate accompanies each part; these, however, are not 
numbered and will be somewhat troublesome to cite. 
Photographs of the Fruits of American Plants. Dr. C. F. 
Millspaugh, of Binghamton, N. Y., has sent us some photographs 
of the fruits of Actea spicata, var. alba, and Celastrus scandens, 
which are intended to be attached to Herbarium sheets. These 
are especially desirable in species— like those of Acte@a—whose 
fruit is difficult to preserve. We hope that Dr. Millspaugh will 
find it possible to produce photographs of other species and give 
botanists opportunity to obtain them. 
Cypripedium arietinumin China. Ina recent number of the 
Bulletin of the Botanical Society of France, M. Franchet notes 
the discovery of this plant in the mountains of Yun-nan, South- 
_ western China. This interesting fact adds another link to the 
- chain of evidence of the common origin of the Eastern North 
American and Eastern Asiatic Floras,
