1913] CURRENT LITERATURE 239 
TREBOUX,”™ working at Nowotscherkassk in southeastern Russia, reports 
the results of a number of infection experiments carried out in that region. 
Since the literature on the subject was not available to him, he was unable 
to consider the work of former investigators. The following is a list of the 
successful infections. Aecidiospores from Ranunculus illyricus L. infected 
Festuca ovina L. (Uromyces Festucae Syd.). Aecidiospores from Sium lanci- 
folium MB. infected Scirpus maritimus L. (Uromyces lineolatus [Desm.] 
Schroet.). Aecidiospores from Euphorbia virgata W.K. infected Astragalus 
hypoglottis L. (Uromyces Astragali [Opiz.] Sacc.). In former experiments, 
uredospores from Astragalus virgatus Pall. infected A. cicer L., A. glycyphyllus 
all., A. ponticus Pall., A. cruciatus Link., A. hamaeus L., A. placatus Lam., 
A. tianchanicus Bunge., A. viciaefolius DC., and A. virgatus Pall. Apparently 
there is no specialization of forms within this species of Uromyces. Aecidio- 
spores from Euphorbia virgata W.K. and E. Gerardiana Jacq. infected Caragana 
frutescens DC. (Uromyces Genistae-tinctoriae [Pers.] Fuckel). Other legumi- 
nous plants, including Astragalus and M edicago, were not infected either by 
aecidiospores or by uredospores. <Aecidiospores from another aecidium on 
Euphorbia virgata infected Medicago falcata (Uromyces striatus Schroet.), 
but not Astragalus, Caragana, and others. Aecidiospores from Cichorium 
Intybus L. infected Juncus Gerardi Lois (Puccinia Junci [Strauss] Winter). 
A sowing of aecidiospores from Taraxacum serotinum W.K. produced only 
uredospores, probably those of Puccinia silvatica Schroet., on Carex stenophylla 
Wahlen redospores of Puccinia Cesatii Schroet. on Andropogon Ischaemum 
L., which had persisted during an unusually severe winter, were capable of 
germinating and infecting that host in spring. Apparently this rust lives 
through the winter in that region by means of uredospores which have thick 
walls. Teleutospores of Puccinia Stipae (Opiz.) Arthur from Stipa Lessingiana 
Trin. infected Salvia aethiopis L., S. nutans L., S. silvestris L., Thymus serpyl- 
lum L., and Ajuga chia Schreb. 
STRELIN,” in a series of cultures, shows the relation between the primary 
uredinia (Uredo Muelleri Schroet.) and secondary uredinia and telia of 
Kuhneola albida (Kiihn) Magnus, confirming the work of Jacky showing that 
these spore forms all belong to the same rust. STRELIN also shows that the 
fungus persists through the winter by means of the spores of the primary 
uredinia which are formed in July and August. The primary uredospores 
can infect the following spring only the old leaves which have persisted through 
the winter.—H. HassELprING.
