Evolution in Leaves. Mrs. W. A. Kellerman. (Trans. Kans. 
Acad, Sci. xii. 168-173, illustrated). 
This is a statement of some facts observed in the lobing of 
leaves and development of stipules, followed by a discussion of 
the significance of the facts in relation to the forms of leaves. 
Rubus villosus, Vitis quinquefolia, Rhus Toxicodendron, Sam- 
bucus Canadensis, Negundo aceroides, Symphoricarpus racemo- 
sus and Cimicifuga racemosa are made use of as examples, and 
Rubus, Rosa, Tecoma and Vitis, are the subjects of illustration. 
There is also a list of plants designed to show that large leaved 
plants harbor fewer insects than finely divided ones, and that, 
therefore, the evolution from entire to dissected leaves was not 
due to an attempt of the plant to escape from the ravages of in- 
sects. The author is manifestly in sympathy with the views of 
Grant Allen, that leaves become dissected in their efforts to 
obtain air and sunlight. A. Hi. 
Flora Franciscana. Au attempt to Classify and Describe the 
Vascular Plants of Middle California. Edward L. Greene, 
(Part I, 8vo. pp. 128. San Francisco. Issued March 30, 1891). 
A portion of the collected results of Prof. Greene’s critical 
studies of the Flora of this part of Western America, extending 
over many years, is now, happily, given to the world. It is the 
first time that he has essayed to present a descriptive synopsis 
of the flora of a region, or anything in the nature of monographs 
of genera, all his available time for writing, up to the present, 
having been needed for the separation and characterization of 
new or obscure species, the discussion of questions of nomencla- 
ture, and other work of a non-consecutive character on the 
' plants of what has been, botanically, a little known area. Amer- 
ican botanists have awaited the production of the work now 
_ noticed, with impatience, for it has been felt that he, and he only, 
could satisfactorily bring together the multitude of facts and ob- 
servations which he has recorded in the publications of the Cali- 
fornia Academy of Science, Pittonia and the BULLETIN. Depart- 
ing entirely from the long-followed sequence of natural orders _ 
established by the elder DeCandolle, the Leguminose are placed
