No. 15, Dec., 1890, Agr’l Ex. Sta., Manhattan, Kans. (Issued March 20,1891.) 
Continue work of previous year upon the subject, giving results of extended 
experiments in the prevention of the disease, including the test of 155 treat¬ 
ments of seed previous to plantiug. Give numerous observations as to the 
amount of smut, concluding from a careful estimate that there was in the State 
of Kansas a loss in 1890 of between 6 and 7 per cent through smut. Report 
superiority of Jensen hot-water treatment over all others for the prevention of 
the disease, requiring 15 minutes’ immersion in water at 132^° F., but recom¬ 
mend, tentatively, use of potassium sulphide one-half per cent solution, 
in which seed may be immersed 24 hours. Find various other chemicals 
while preventing the smut greatly injure the stand. Announce the dis¬ 
covery for the first time of a “hidden smut” which, while not apparent 
without tearing away the glumes, destroys the grain completely. Conclude 
seed from clean field will produce a crop free from smut, but if adjoining 
fields are smutty the oats from a clean field will in a few years become 
infected with the disease. 
292. Magnus, P. Ueber das Auftreten eines Uromyces auf Glycyrrhiza in der alten und in 
der neuen Welt, (mit Tafel xx). Berichte der deiitschen botanischen Gesell- 
schaft. Band vm, Heft 10, pp. 377-384, December 30, 1890. Discusses at 
some length the synonymy of the various species of Uredinece described on 
Glycyrrhiza giving history of each description. Concludes the American 
species found upon Glycyrrhiza lepidota by various authors and variously 
named, to be identical with that upon Glycyrrhiza glahra, L., of the East. 
Draws the conclusion from the fact that the variation of the species of Gly¬ 
cyrrhiza has become specific and the parasite remained the same; that Uro¬ 
myces glycyrrliizce was parasitic upon plants of the genus Glycyrrhiza before 
the separation of North America and Europe in the Tertiary period. “Ich 
glaube daher nicht zu viel zu behaupten wenn ich sage, dass Uromyces gly- 
cyrrhizos ein Parasit ist, den Glycyrrhiza seit den Zeiten bewolint, da Norda 
merika und Europa noch ein einheitliches Florengebiet bildeten.” Gives 
preference to name Uromyces glycyrrliizce , (Rabh.) Magnus, with the follow¬ 
ing synonymy: Puccinia glycyrrliizce, Rabh., in Klotzsch, Herb, mycologi-
