 of longitude west of Greenwich, comprising somewhat above 

 8,000 square miles in area. Within these limits there are found :

Total Anthophyta 1,919 



Total Pteridophyta 76 



Total Bryophyta . 461 



Total Thallophyta.. 3,021 



Total Protophyta 164 



The catalogue will prove useful not only to local collectors, on 

 account of the great care with which the stations have been 

 given but will be of service to all those who are interested in the 

 problems of geographical botany. G. l. g. 



2. List of Plants. — We have to note the following recent lists, 

 mostly with annotations. (1.) A list of plants collected by Dr. 

 E. A. Meai'nes, Arizona, by De. N. L. Britton. In the same 

 number is printed also a paper by Dr. Rusby on the general 

 floral chai'acters of the San Francisco and Mogollon Mountains 

 of Arizona and New Mexico. Trans. N. Y. Acad. Sc, vol. viii. 

 (2.) List of plants collected by Dr. E. Palmer, in Lower Califor- 

 nia in 1889. By George Vasey and J. N. Rose, from Proceed- 

 ings of U. S. National Museum, vol. xi. (3.) List of plants 

 collected by Dr. E. Palmer in 1888, in Southern California, by 

 the authors of the list above noticed, also by the same, the fol- 

 lowing : (4.) List of plants collected by Dr. E. Palmer, at Lagoon 

 Head, Cedros Island, San Benito, Guadalupe, and the Head of 

 the Gulf of California. The two last are printed as No. 1 of the 

 Contributions from the National Herbarium, Washington. (5.) 

 Plants from Baja, California, by T. S. Brandagee, including sup- 

 plementary papers by Dr. George Vasey, Dr. C. F. Mills- 

 paugh, Dr. H. W. Harkness, and others, Proc. Cal. Acad. Sc. 

 ser. 2, vol. ii. (6.) Provisional list of the Plants of the Bahama 

 Islands, by Professor John Gardiner, University of Colorado. 



3. Preparation of sections for the study of the development of 

 organs. — Goethart, (Bot. Zeit. June 6, 1890) makes a sugges- 

 tion in regard to the use of Elder-pith for the cutting of sections 

 which has proved useful in some rather troublesome cases. From 

 the pith, a long vertical slice is made which fits by means of a 

 tongue into a notch on the larger part, and thus a firm grasp is 

 obtained for the preparation placed between the two. Ai'ound 

 the upper part a very thin platinum wire is wound, and the whole 

 is then placed in alcohol to harden. Exceedingly thin sections 

 can be made in this manner ; the specimens can be placed at will 

 in any position and kept there firmly. g. l. g.
