A catalogue of 1194 Phanerogams, 20 Pteridophytes, about 
130 Bryophytes and a large number of Fungi, the result of the 
author’s eight years diligent botanizing in Plaquemines Co., 
Louisiana. The list is prefaced by some general remarks re- 
garding the Flora, the great abundance of lower cryptogamous 
plants being explained by the great humidity. Copies of the 
pamphlet (which appears to have been printed in St. Etienne, 
France) may be had of the author for twenty-five cents.

The results obtained are as follows: The apical growth is from 
a cluster of cells, each of which is at the tip of one of the longi- 
tudinal filaments; each cell divides to form the adult filament 
and the cortex. The diaphragm and bulb-cells originate from 
the filaments as outgrowths, and the branches each have their 
origin opposite a filament. 
Comparative Chemistry of Higher and Lower Plants.—Helen C. 
DeS. Abbott. (Amer. Nat., xxi. pp. 719-730 and 800-810;

This is an abstract of a lecture delivered in April last, before 
several of the Washington societies on a subject which has as yet 
obtained but little recognition in America. Among the many 
interesting suggestions, we note ‘the largest ash-percentages 
_.are found among those plants lower in the evolutionary scale,” 
and that the green of chlorophyll is generally darker in plants of 
_, more complex organization, though to this we might offer an 
~ exception in the dark-greens of Amthoceras and other Hepatics.
