monograph of this genus.— L. Damazio (Bull. Soc. Bot. Geneve II. 6:171- 

 172. 1914) describes and illustrates a new fern (Elaphoglossum Beauverdii) 

 from central Brazil.— C. De Candolle (Bull. Soc. Bot. Geneve II. 6: 107- 

 126. 1914) describes new species in Piper, Cabralea, Gaurea, Cedrela, and 

 Begonia from Paraguay. The same author (Not. Syst. 3:38-44. 1914) has 

 published several new species of Piper and Peperomia, including 4 from Mexico, 

 and (Rep. Sp. Nov. 13:304-311. 1914) describes 16 additional species in these 

 genera from Bolivia.— L. Dirls (Philipp. Jour. Sci. Bot. 8: 157-158. 1913) has 

 published three new species of Menispermaceae from the Philippine Islands. — 

 S. T. Dunn (Notes Roy. Bot. Gard. Edinb. 8:153-171. 1913) in an article 

 entitled "Notes on Chinese Labiatae" describes several species new to science 

 and proposes a new genus, namely Parlamium, based on specimens collected 

 in Yunnan by Mr. Henry. — A. Engler (Bot. Jahrb. 51:225-471. 1914) in 

 cooperation with several specialists has published "Beitrage zur Flora von 

 Afrika xliii." Approximately 200 new species and varieties of flowering plants 

 are described, and the following new genera are proposed: Rhodohypoxis Nel 

 of the Amaryllidaceae, Melliniella Harms of the Leguminosae, Gilgiochloa 

 Pilger of the Gramineae, and Neosloetiopsis Engler of the Moraceae.— A. W. 

 Evans (Bull. Torr. Bot. Club 41:577-616. pi. 21. 1914) under the title 

 "Report on the Hepaticae of Alaska" includes the description of two new 

 species of Plagiochila and one of Radula from Alaska.— J. S. Gample (Philipp. 

 Jour. Sci. Bot. 8:203-206. 1913) under the title "Some additional bamboos 

 of the Philippine Islands" records further data concerning this group of plants 

 and adds a new species from Mindanao.— L. S. Gibbs (Jour. Linn. Soc. 42:1- 

 240. pis. 1-8. 1 9 14) under the caption "A contribution to the flora and plant 

 formations of Mount Kinabalu and the highlands of British North Borneo" has 

 published an important contribution to our knowledge of the flora of Borneo. 

 Prominent specialists have cooperated in the identification of the plants and 

 upward of 80 species are described as new to science. The following new 

 genera are proposed: Phyllocrater and Cowiea Wernham of the Rubiaceae, 

 Sigmatochilus Rolfe of the Orchidaceae, and Lophoschoenus Stapf of the 

 Crepyaceae— J. M. Greenman. 



Phenomena of parasitism.— Differences in the behavior of Monilia cinerea 

 and Botrytis cinerea are brought out by the studies of Cooley and of Brown. 

 These fungi represent the two sections of the genus Sclerotinia the members of 

 which have frequently furnished material for investigations designed to throw 

 light on the phenomena of parasitism. While the apothecial organs of these 

 fungi are much alike, their conidial fructifications are widely different; but 

 more interesting from a biological standpoint is the difference in the mode of 

 formation of sclerotia with which the contrasting behavior brought out in the 

 two papers can perhaps be correlated. Cooley,* who investigated the be-
