412 BOTANICAL GAZETTE [May 
an account of the natural vegetation of alkali lands (pp. 63-75) by J. Burtt 
Davy, illustrated with eight fine plates from photographs. The plates show 
Frankenia grandifolia campestris Gr., Distichlis spicata (L.) Greene, Atriplex 
polycarpa (Torr.) Wats., Bigelovia veneta (H. B. K.) Gr., Su@da Torreyana 
Wats., Sporobolus atroides Torr., Allenrolfea occidentalis (Wats.) Kuntze, and 
Modiola decumbens Don. 
he report of the Connecticut station for 1897 is issued in parts, and part 
three (pp. 159-222) is entirely devoted to botany. The articles are by W.C. 
Sturgis, and present, with much fullness, a study of the mildew of lima beans 
(Phytophthora Phaseoli Thax.), stem rot of carnations, which was found to 
be due to a Fusarium, prevention of fungous diseases of celery and apple, 
and an extended classified index to the literature of fungous diseases, found 
chiefly in the publications of the U. S. Department of Agriculture and the 
state experiment stations. 
The Arizona report for 1897-8 is very brief, containing only 40 pages. 
The botany (pp. 160-169) by J. W. Toumey treats especially of root-rot of 
Alfalfa, and sunburn of fruit trees, the latter being due to the action of a hot 
sun while the plants are in a wilting condition. 
n the Wisconsin report for 1897-8 there are two important botanical 
studies by E. S. Goff. The first is an investigation of the resumption of 
root growth in spring (pp. 220-228), showing that the rootlets of trees and 
shrubs do not die away during winter, as*usually taught, but that growth is 
resumed in spring where it ceased in the previous autumn. The second is a 
study of the morphology and habits of the strawberry plant (pp. 229-238). 
Both are well illustrated by cuts. 
In the Vermont report for 1897-8 both the botanist and horticulturist write 
upon subjects that are largely botanical. The botanists, L. R. Jones and W. 
A. Orton, present a variety of topics (pp. 189-236). Valuable results are 
~ecorded in spraying potatoes and apples for fungous diseases, and in treat- 
*ng potatoes, especially with formalin, for scab. In 1897 the asparagus rust 
and club-root of cabbage were first reported in the state. A list of the 
parasitic fungi of the state with their hosts includes 17 species of Phycomy- 
_ cetes, 27 of Erysiphez, 15 of Ustilaginez, and 80 of Uredinex. There are 
interesting observations on weeds, and on impurities in clover seed. A study 
of the flow of maple sap shows close correspondence between changes of 
temperature and rates of flow, and by use of lithium it was found that the 
sap flowed equally well up or down the trunk, but very slowly in a radial 
direction. F. A. Waugh, the horticulturist, reports (pp. 237-306) with geet 
fullness upon the study of plums, théir pollination, self-sterility, hardiness 
and blossoming seasons, to which is added a monograph of the Wayland 
group of plums, all amply illustrated. There are also notes on lilies, 
physiological constants, on use of enzyms in germination, and on winter 
killing of buds, all treated with originality, and full of valuble facts.—J. C. 4
