The Index to recent Literature relating to American Botany. 
Following out a recommendation of the Committee on Biblio- 
graphy and Typography of the Madison Botanical Congress,* 
the form of our monthly record of American Botanical Literature 
will be changed in the next volume, so that the citations will be 
by authors instead of by subjects. It will be set in smaller type 
than the rest of the BULLETIN, and the titles will be printed off on 
library cards if a sufficient number of subscribers to these cards is 
_ obtained to justify their production. The proposed style of these 
cards is as here illustrated: 
Lagerheim, G. von. Ueber das Vorkommen von Europzischen 
Uredineen auf der Hochebene von Quito. Bot. Centralb. 54: 324- 
331. 1893. 
Puccinia coronata and P. gramints are recorded as occurring in Ecuador, and 
Fusarium uredinis is described as new. 
Matthew, W.D. A Study of the Scale characters of the Northeast- 
ern American Species of Cuscuta. Bull. Torr. Bot. Club, 20: 310—- 
314. pl. 164, 165. 10 Aug. 1893. 
_ Description and illustration of the corolla-scales, calyx and ovary of twelve species. 
All correspondence concerning these cards should be addressed 
to 
Tue CAMBRIDGE BOTANICAL Suppcy Co., 
CAMBRIDGE, Mass.

It is hoped that the record of papers may be made even more 
complete than hitherto, and if omissions are noted, it is earnestly 
requested that the attention of the editors may be called to them, 
The various journals and serial publications have been divided up 
among the editors, and Prof. Lucien M. Underwood, Prof. Con- 
way Macmillan, Mr. F. V. Coville and Dr. S. Ely Jelliffe, who have 
kindly consented to codperate in the work.
