future be mainly concerned with the floras of Russia and the 
adjacent countries. The collections are available for study by 
visitors on week days from 11 to 3 o’clock. 
Library.—The library has until now been lodged in the same

It only remains to add a few words concerning the official publi- 
cations emanating from the Imperial Botanic Garden. The prin- 
cipal journal, “ Acta Horti Petropolitani,” has already been 
mentioned. It has run to more than 30 volumes, with about 18,000 
pages. To this was added in 1901 the “ Bulletin du Jardin 
Impérial Botanique de St. Petersbourg,” and in 1902 the “ Journal 
traitant les moyens de combattre les maladies et les lésions des 
plantes cultivées et des plantes sauvages utiles, which in 1907 was 
superseded by another journal under the title “ Les maladies des 
plantes,” and finally in 1912 the “ Annales de la station d éssais de 
semences.” The annual seed lists (Index—-now “ Delectus”— 
Seminum quas Hortus Botanicus Imperialis Petropolitanus pro 
mutua commutatione offert), which were started by F. E. L. 
Fischer in 1835 and the earlier issues of which contain descriptions 
of many new species, have been continued so far without a break.
