the excretion from the epidermis of slime, and this is accompanied by 
decrease in the amount of cytoplasm and usually by a great increase in the 
chromatin, while the nucleolus becomes smaller. The investigations point to 
the nucleus as the chief center in the cell, initiating and carrying out the 
ac toa chemical and physical reactions. 
There is much detail in this paper of 116 pages and apparently a very 
complete summary of the literature, together with much suggestive specula- 
tion interesting to the student of the plant cell.—B. M. Davis. 
ITEMS OF TAXONOMIC interest are as follows: A. W. Evans (Bull. Torr. 
Bot. Club 27:97-104. 1900) has described a new genus of Hepaticae (Acro- 
mastigum) from the Hawaiian islands, heretofore referred with doubt to 
Mastigobryum (Bazzania).—E. L. Morris (27d. 105-119) has published a 
revision of the species of Plantago commonly referred to P. Patagonica Jacq., 
in which fifteen species are recognized, six of them being described as new.— 
E. B, ULinE (Field Columbian Mus. Bot. Series 1: 413-422. pls. 22-24. 
1899) has described a new genus (/iginbothamia) of Dioscoreacee from 
Yucatan, a new Dioscorea, and five new species of Amaranthacez.—In the 
current number of Engler’s Botanische Jahrbiicher (28 : 145-272. 1900) the 
present series of papers (XIX) on the African flora is completed. E, GILG 
Mescribes a new genus (Brachythalamus) of Thymeleacez ; E. GILG and 
K, 
KRANZLIN presents the African Orchidacez, describing two new sss 
(Angraecopsis and Schwartzkopffia.) In the same number P. HENNINGS 
publishes a list of Japanese fungi, describing a new genus asian of 
Hydnacee.— In Deutsch Bot. Monats. (18: 26-27. 1900) W. N. SUKSDORF 
publishes three new species of Saxifraga, and a new variety of Vicia Ameri- 
cana, all from Washington.— J. M. C
