■pages. The narrow limits into which the different life-zones are com- 

 pressed in these southern mountains, renders accurate delimitation a per- 

 plexing task, not to be accomplished without thorough field study; but for 

 San Jacinto this task has now been performed most successfully. The 

 flora of no other like area in the state has received so complete elucidation. 



The remaining pages are occupied* by a catalogue of the Sperma- 

 tophytes growing in the pine belt. These number 456 species and varieties, 

 all but one having been collected by Mr. Hall. The following plants are 

 here for the first time reported from Southern California : 



Panicum thermale, Bolander; Phleum alpinum, L. ; Poa alpina, L. ; 

 P Buckleyana, Nash; Trisetiim nutkaiense, S. & M. ; Carex Hallii, Bailey; 

 C. niidata. Boott ; C. Preslii, Steud. ; Listera convallarioides, Torr. ; Po- 

 tentilla lactea, Greene. Mr. Hall also finds Sambucus Mexicana, Presl., 

 a species whose presence in Southern California has been questioned. He 

 also refer to Piniis Hexilis, James, the white-barked pine of our higher 

 mountains, heretofore regarded as P. albicaulis, Engelm. The new species 

 proposed are Broiiiiis Porferi assimilis, Davy; Elyinus Parishii, Davy and 

 Merrill; Poa Howellii Chandleri, Davy; Stipa calif ornica, Merrill and 

 Davy; Oxytheca marginata, Hall; an elegant little plant; Potentilla acu- 

 minata, Hall; P. callida, Hall; Monardclla macrantlia vars. pinetorwn and 

 arida. Hall; Erigevon Jacintens, Hall; and Hiilsea z'estifa callicarpha.

Those interested in the habits of the Aboriginal Indians will find 

 Mr. Chestnuts "Plants used by the Indians of Medocino County" a mine of 

 interesting facts. The food and medicinal plants used by the Indians are 

 enumerated as well as the methods whereby they are rendered available for 

 use. The Indians has so modified his old habits that this is probably the 

 last work of the kind that can be written from direct observation. 



"The thirteenth annual report of the Missouri Garden" is practically 

 a Monograph on the Yuccege, by Dr. Treaiease. Coming from the pen of a 

 specialist the work is a most desirable one and its value is very much en- 

 hanced by 99 plates illustrating every known species, with maps showing 

 their distribution in N. America. The author has considerably modified 

 the nomenclature previously adopted b}- himself and other botanist. Our 

 Western species as amended now are Hesperoyucca Whipplei, Clistoyucca 

 arborescens, Yucca Moliavensis. To the southern species many new 

 varieties have been added and a new Genus Samuela has with two species 

 has been added to include the gamphyllous forms. The variety gfamini- 

 fotia of TT. Whipplei is not endorsed though it appears to the writer to be 

 desiring of at least varietal rank. 



Through the effort of ]>[r. Braunton the first accurate catalogue of our 

 ornamental shrubs and plants has just been issued by the Sycamore Grove 

 Nurseries. As a short description accompanies each species, it becomes a 

 useful handbook.
