IDENTIFYING EQU1SETUMS. 



AN interesting method of identifying the horsetails is by the 

 examination of their stems. Nearly all have very charac- 

 teristic outlines. Below is an illustration of several of 

 our common species, which we reprint from "Wayside and Wood- 

 land Blossoms," by permission of Messrs. F. Warne & Co., N. Y. 



HALF-SECTIONS THROUGH HORSETAIL STEMS. 



1. — Equisetum maximum. 4- — E.-sylvaticurn. 



2. — E pratense. 5 — E.Jluviatile. 

 3 — E. arvense. 0. — E. paluntre. 7. — E hycmale. 



LYCOPOD1UM CAROL INI A MJH. 



ONE of the daintiest of our American Lycopodiums is L. 

 Carolinianum. Its furthest habitat north \ seems to be 

 New Jersey, in the pine barrens of which state it is abund- 

 ant, loving to frequent sandy swamps. The sterile stems lie flat 

 on the ground and clings so tenaciously to their sandy bed that it 

 is difficult to collect the plant except in fragments. At first 

 sight it might readily remind one of a rather coarse selaginella, 

 but the slender, delicately poised fruit spikes will readily distin- 

 guish it from that tribe .— C F. Saunders. 



Mr. E. C. Kent of East Wallingford, Vt., has discovered a form 

 of Lycopodium clavatum in his vicinity that produces sterile stems 

 twenty inches high.
