range of subject matter. They indicate that 

 the work now being done by the university is 

 thoroughly specialized, and is organized on 

 the broadest possible basis. The number of 

 contributors is larger than in any previous 

 year, and includes authors of a wide range of 

 training and interest. In total bulk, the con- 

 tributions of the period just passed (Y82 pages, 

 38 plates, 235 text figures and 3 maps) are 

 larger than ever before in the history of 

 anthropological work in California.

 ANOTHER KKY TO SACOARDO 



A COUPLE of years ago a brief notice was 

 made in Science of a typewritten English key 

 to Saccardo's " Sylloge Fungorum " prepared 

 for the use of the myeological students in the 

 University of Nebraska, and the statement 

 was made that a few extra copies might be 

 obtained on application. The results of the 

 announcement were surprising. At once re- 

 quests for the key came from all parts of the 

 country, and within a week the small stock of 

 the books was all sold out, and it became evi- 

 dent that a reissue or a new edition must be 

 prepared. This has now been done by Pro- 

 fessor Dr. Clements, of the University of Min- 

 nesota, and proof is now being read upon the 

 new edition, which is to be printed and 

 brought out as a small book. It will contain 

 keys to " spore sections," to orders and fam- 

 ilies, and to the genera, besides some handy 

 indexes, glossaries, etc. As it has been an- 

 nounced to be " ready by September 20 " fur- 

 ther notice may be deferred until the appear- 

 ance of the completed work. In the mean- 

 time those who are especially interested in it 

 may communicate with the author, as above, 

 at Minneapolis. 



A NEW COLORADO BOOK 



Professor Kamaley, of the University of 

 Colorado, has given us in his " Wild Flowers 

 and Trees of Colorado " a charming little 

 book intended to serve as an introduction to 

 Colorado plants. In less than a hundred 

 pages he leads the beginner far on the road to 



a knowledge of the vegetation of this state. 

 He first discusses the general aspects of Colo- 

 rado vegetation (ecology we often have called 

 it in these later years) and then takes up the 

 forests and forest trees of the state. He recog- 

 nizes five zones or belts of vegetation, namely, 

 the plains zone, foothill zone, montane zone, 

 sub-alpine zone and alpine zone. These are 

 admirably illustrated by many half-tone repro- 

 ductions of well-selected photographs. The 

 forest trees are briefly described by means of 

 convenient keys, and the text is helped greatly 

 by many illustrations. A bibliography in- 

 cluding thirty-one titles completes this very 

 iiseful book. 



THE MINNESOTA BOTANICAL STUDIES 



The resumption of publication of the widely- 

 known " Minnesota Botanical Studies " is a 

 matter of more than ordinary interest to bot- 

 anists. The " Studies " were begun fifteen 

 years ago by Professor MacMillan, under 

 whom two fine volumes were completed, and 

 parts 1, 2 and 3 of the third volume were 

 issued, publication ceasing five years ago. 

 Now under Professor Clements, part 1 of 

 volume IV. makes its appearance with the 

 same style of cover, paper and t.ypography. 

 In the present part, which covers 132 pages, 

 there are six papers, viz : " Embryo-sac Devel- 

 opment and Embryology of Symplocarpus 

 foetidus," by C. O. Rosendahl ; " The Seeds 

 and Seedlings of Caulophyllum thalictroides," 

 by F. K. Butters ; " Influence of Physical 

 Factors on Transpiration," by A. W. Samp- 

 son and L. M. Allen ; " Two Basidiomycetes 

 New to Minnesota " and " The Pezizales, Pha- 

 cidiales and Tuberales of Minnesota," by D. 

 S. Hone; "A New Genus of Blue-green 

 Algae," by F. E. Clements and H. L. Shantz. 

 The promise is made, also, that an index and 

 title page " will be furnished at an early date " 

 for the three preceding parts which are to 

 constitute volume III.
