There are appendices (i) 

 school crarden: (2) on bio- 



logical collections of plants; and (3) on simple methods (mostly de\ised by the

Diatoms of the Pacific. — Mann^ has published the results of his investigation 

 of the diatoms collected by the Albatross of the U. S. Bureau of Fisheries, during 

 its fishery and deep-sea investigations in the Pacific in the years 1888-1904. The 



F 



contribution contains a synoptical catalogue of the species, the data of the stations 

 at which the diatoms were collected, and a very useful bibliography. The 51

The 



large genera are Navicula (54), Coscinodiscus (34), and Biddulphia (30). — J. M. C. 



Portraits of botanists. — The third and fourth parts of Dorpler's series of 

 portraits of botanists have been issued. A description of the general character of 

 the series was given in this journal (42:496. 1906) upon the appearance of the 

 first two parts. The third part contains the portraits of Rudbeck, Linne (4), 

 Haller (2), Scopou, Jacquin, and Allioni; the fourth part, Wxjefen, Ingen- 

 Housz, Hedwig, Gaertner, Kolreuter, Schreber, Pallas, Ehrhart, 

 Thunberg, and Lamarck. — J. M. C, 



Engler's Syllabus. — That the development of our knowledge of the relation- 

 ships of plants is very rapid is evidenced by the appearance of the fifth edition 

 of Engler's SyllabusJ The most recent information about Cycadofilices was 

 even so recent that it was inserted by means of a paster. It is a great boon to 

 botanists that this publication keeps so well abreast of current knowledge, for it 

 is a volume of daily consultation in every working laboratory. — ^J. M. C. 



Flora of the Canadian Rockies, — ^Miss Farr 



;ported by other botanists 



has presented a list of 763 species of vascular plants, 38 of which are pteridophytes
