1889.] Botany. 165 
Some Experiment Station Botany. — A dozen or so of 
the bulletins issued by the Agricultural Experiment Stations 
contain matter more or less botanical in nature. From these 
the following notes have been rather summarily made. 
In Dakota the growth of planted trees during the two years 
1886 and 7 was watched and noted. — In Missouri forty "varie- 
ties" of grasses were grown and their deportment noted under 
grasses and clovers extending through fourteen years have 
been summarized and recorded in Bulletin No. 2. — In Florida, 
the grasses have been grown and watched in like manner. — 
In Indiana, Professor J. C. Arthur ( in Bulletin 15 ) describes 
popularly, but accurately, the structure of the potato tuber. 
The treatment of the subject is admirable and aside from its 
horticultural value the paper is of value and interest to bot- 
anists. — In Minnesota the Bulletin for July, contained a pop- 
ular account of the organs of fertilization in plants with es- 
pecial reference to the artificial pollination of cultivated 
plants. — The August bulletin of the Iowa station contained 
an interesting paper on corn tassels and silks, and a popular 
discussion of grasses and other forage plants. Mr. Crozier's 
notes upon the wild grasses of Northwestern Iowa are valua- 
ble, although some of the English names used by him are 
misleading and confusing. "Blue Stem" for Agropyrum 
glaiicum and " Buffalo Grass " for Boutelona oligostachya ought 
not to be tolerated.— In Texas, Bulletin 3 is devoted to popu- 
lar notes on native and introduced grasses and other forage 
plants.— Bulletin 4, of the Minnesota station, devotes sixteen 
pages to " Fungi which kill insects, " by Otto Lugger. The 
paper is a well written summary derived from various sources, 
with observations by Mr. Lugger, and is illustrated by nine 
cuts two of which are original.— The November bulletin, from 
the Iowa station, includes a short paper by C. P. Gillette on 
Chinch-bug Diseases (^;«///.frt sp. and Micrococcus insectoruni) 
and " Some Injurious Fungi" by Mr. Crozier. The latter are 
Apple Blight, {Micrococcus amylovorus Burrill. ) Potato Rot 
( Pliytophtkora infestans DeBary, ) Grape Rot ( LcEstadia 
bidwillii Sacc ) and Ergot, ( Gaviceps purpurea Tul.) Mr. 
Craig contributes some notes on Promising Grasses of Mon- 
tana, and Idaho, based upon personal observations made 
during a hasty trip taken at the suggestion of the Governing 
Board of the station.— In New Jersey, Mr. Hulst reprints at 
length from Worthington Smith's account in "Diseases o{ 
Field and Garden Crops," of Club-Root {Plasmodiophora 
brassicce Wor.) Some personal observations are added.— 
Professor Kellerman makes a preliminary Report on Sorg- 
hum Blight ( Bacillus sorghi Burrill) in the December bulletm
