covered with sand, but this does not prevent a fine growth of 

 trees. The hill west of the railroad station is a good example of 

 this and it is here that the lycopods grow in great profusion. 

 There are four species, viz.: Lycopodium tristachyum, L. com- 

 planatum, L. annotiniun and L. clavatum, besides an occasional 

 L. obscurum. The most common of all these is L. complanatum. 

 Lycopodium tristachyum grows in the woods which are composed 

 of deciduous trees, maple, beech, birch, etc. The soil is pure 

 sand. When you come to an open spot this species is replaced 

 by L. complanatum, which does not seem to be as fond of the 

 shade as its congener. L. tristachyum does not fruit so freely as 

 L. complanatum and there are many barren shoots. As has been 

 noticed before, the running stems lie below the surface of the soil, 

 but the habit of the plant is the same as that of this whole section. 

 It throws up single stems at intervals which, at a distance of about 

 2 inches from the soil begin to branch and produce fan-shaped stems 

 covered with leaves in 4 ranks, but not flat as in L. complanatum. 

 These leafy stems are much longer and slenderer and more droop- 

 ing than in L. complanatum. There are sometimes as many as 4 

 long fruit-peduncles produced from different parts of the main 

 upright stem and not in the least connected with each other, but 

 generally growing to the same height, so that there may be an 

 inch or two of difference in their length. At the top, each of 

 these bears 2 to 4 spikes about an inch long, preferably 4 of 

 them. Here again there is a difference which cannot be detected 

 in the pressed plants. In L. complanatum the short pedicels of 

 the spikes make an elbow from which the spikes stand up erect, 

 so that in case there are 4 spikes they form an exact square, or 

 if 3 only, then an exact triangle, the spikes standing up like can- 

 dles out of a candelabrum. In L. tristachyum the pedicels are 

 more slender and rise directly from the spot where they branch, 

 without the elbow but in an oblique direction. This difference is 

 very noticeable in the growing plant, but not particularly so in 

 the pressed specimens. 



Prof. Charles H. Peck, our New York state botanist, informs 

 me that he has gathered L. tristachyum in Essex Co., N. Y., and 

 that his impression is that it grows there more plentifully than
