Letters on the Diseases of Plants by N. A. Cobb, is 
Miscellaneous Publication No. 666 of the Department of Agri¬ 
culture, Sidney, New South Wales. It is a pamphlet of 133 
pages; contains over 150 original illustrations; seven original 
colored plates; and four copied plates. The diseases and the 
parasitic fungi are outlined in popular form and remedies sug¬ 
gested. 
On the Fertilization, Alternation of Generations 
and General Cytology of the Uredineae by Vernon H. 
Blackman, printed in the Annals of Botany, Vol. XVIII, July 
1904, is a very important contribution, but space is wanting for 
even a meager outline of the paper. A few sentences may be 
quoted: “The mature teleutospore is uninucleate and gives rise 
to four uninucleate sporidia, from which a mycelium is developed 
with the nuclei arranged singly, usually in separate cells. The 
spermatia produced on this mycelium are uninucleate, but in the 
young aecidium the nuclei become paired (forming binucleate 
cells) and divide together in very close association. This paired 
condition is then persistent throughout the rest of the life-cycle 
(aecidiospores, uredospores, and mycelia produced from them) 
up to the formation of the teleutospores, which in the young state 
are binucleate, but when mature become uninucleate by the 
fusion of the two paired nuclei. ... A study of the struc¬ 
ture of the spermatia of the Uredineae shows that they have 
the characters not of conidia but of male cells. . . . The 
fusion in the teleutospores of the two nuclei — the direct de¬ 
scendants of those which first became associated in the fertile 
(female ) cell of the aecidium — is clearly not in itself a process 
of fertilization (nor the teleutospore an egg-cell), as Dangeard 
and Sapin-Trouffy supposed, but a mere secondary process, the 
result of fertilization and the preliminary to reduction.”
