These contain articles on Eragrostis Abyssinica, Link. (Teff or 
Thaf), its cultivation and uses. A list of economic and medici-

Chenopodium album.— Cause of the purple coloring of Pigweed 
leaves. Herbert Osborn. (Science, x, p. 166). 
The author finds that the red color which so often occurs on 
the leaves is due to the larval state of a leaf-hopper, (Zham- 
notettix seminudus, Say). 
Chionanthus Virginica, L.—Thomas Meehan. (Proc. Acad. Nat. 
Sci. Phil., June 21, 1887). 
Mr. Meehan notes that dicecism is practically established in 
this plant, although suppression has not gone as far as to abort 
either stamens or pistil. The two forms of the latter are figured. 
Cladosporium fulvum.— Tomato disease. (Gard. Chron., ii, 1887, 
Pp. 532, figs 106, 107). 
Development of the Umbellifer Fruit.—J. M. Coulter and J. N. 
Rose. (Bot. Gaz., xii, p. 237). 
Cherophyllum procumbens was selected as a type, as its fruit 
contains all the structures found in the family. Oil ducts, 
strengthening cells and undifferentiated parenchyma, each were 
traced in their development. 
Eriogonums, Indicative-—F.W. Anderson. (Bot. Gaz. xii., p. 250). 
Green Cotyledons of lemon seeds and Germination inside of the 
Fruit.—Arthur Hollick. (Proc. Nat. Sci. Assoc. Staten Id., 
Oct., 1887). 
Greeneria fuliginea, nouvelle forme de Rot des fruits de la 
Vigne, observée en Amérique. F. L. Scribner et Pierre Viala. 
(Pamphlet, pp. 2). 
In the vineyards of North Carolina this fungus has been found 
on the branches at the insertion of the peduncle at a period between 
inflorescence and the ripening of the fruit, causing it to dry up. 
Hairs of the Peach in relation to Hay Fever.—J. L. Zabriskie. 
(Journ. N. Y. Micros. Soc., iii., pp. 62-68 ; illustrated).
