ing the appearance of a Woronin’s hypha, but nothing was discovered that 
could be directly homologized with an archicarp. 
The basidia bud out from the fertile hyphae, and new basidia are formed 
mainly at the periphery, but some younger ones may later be intercalated 
between the old. Sometimes the fertile hyphae branch to a considerable 
extent (aecidium on Ranunculus), and it is probable that there is present 
more than one fertile hypha in large aecidia. The fertile hyphae in the 
aecidia on Peltandra and Houstonia branch very little. Spores are forme 
after the manner described by Rosen. The sterile interstitial cell is cut off 
from the lower portion of the spore mother cell. In many cases the spores 
contain a triple nucleus in place of the usual double nucleus. The peridium 
appears to result from the metamorphosis of the outer layer of spores or 
spore mother cells. In the aecidium on Sambucus there are even present at 
first the interstitial cells, but these soon disappear with the enlarging of the 
peridial cells and the thickening of their walls.—B. M. 
MINOR NOTICES. 
THE INDIANA ACADEmy of Sciences has been a strong and active society 
from its organization in 1885. In March 1895 the state assumed the expense 
of the publication of its proceedings, three volumes having previously been 
printed by the society. The proceedings for 1894 and 1895 have been printed 
in accordance with the state law, and put into the hands of the state librarian, 
who has only recently distributed them for lack of funds to cover post- 
age. The volume for 1895 contains 298 pages and many well printed illus- 
trations. Its articles embrace a wide range of subjects and are of high 
merit. The principal botanical papers are as follows: Wm. Stuart describes 
experiments which reduced the smut of corn from 13 per cent. to 3 per cent. — 
by using Bordeaux mixture, and to 6 per cent. by using ammoniacal copper 
carbonate ; Severance Burrage gives a new station (Lafayette, Ind.) for P/eo- 
dorina Californica, with notes upon some features of its occurrence ; Stanley 
Coulter reports upon noteworthy Indiana phanerogams and upon some special 
siya as part of the state biological survey, which has been under way — 
for ws; Alida Cu ham also contributes to the survey an account — 
of the distribution i in the state of thirty-seven species of Orchidacez. There 
are shorter articles or notes upon the circulation of protoplasm in Chara by 
D. W. Dennis, microscopic changes in the shrinkage of woods by M. J. 
Golden, microscopic slides as adjuncts: to an herbarium by John S. Wright, : 
and forms of Xanthium Can » and X. strumarium by J.C. Arthur. There 
is an extended report upon ¢ = biological survey of Turkey lake, from wh 
one misses an account of the aquatic or plankton flora, with the a of 
A. 
_a note on the occurrence of a -Rivularia in quan: to form Was 
and of 2 Palmelia that spines tt na sees late antumn.—
