discarded. Fortunately some drawings had been made which pre- 

 served characters easy of interpretation in the light of subsequent 

 discoveries. 



NOTES ON THE GENUS LYCOPODIUM 



By Francis E. Lloyd 



Lycopodium Chamaecyparissus. — Through the courtesy of Mr. 

 D. K. Gilbert, the writer has received specimens of this plant 

 collected at Alder Creek, Oneida Co., N. Y., at which place it 

 grows "plentifully in woods." This establishes the fact of the 

 plant's distribution in this State, from which it was not hitherto 

 reported. " The specimens were gathered in early October, and 

 you will see that the strobiles are old and brown. Those of L. 

 complanatum gathered at the same time and place were still yel- 

 lowish green and show that their time of ripening is much later 

 than that of L. CJiamaecyparissus" writes Mr. Gilbert. This dis- 

 crepancy in the time of ripening, first noted by Austin in New 

 Jersey, is an important physiological character distinguishing the 

 two species. Another observed difference is in the position of 

 the rhizome, which in L. Chamaecyparissus is underground and in 

 L. complanatum prostrate on the surface. Notes by field workers 

 on this point should be made during the coming season. 



L. pinnatum. — In August of the past year Professor S. M. 

 Tracy and the writer were collecting in the vicinity of Biloxi, 

 Miss., and a locality was found where this plant grows in abun- 

 dance, and in perfect form. The horizontal stems are quite pros- 

 trate and thin and the leaves are confined to one plane very closely. 

 The habitat is a very wet white or yellowish clay bank with full 

 insolation. In the same spot L. Carolinianum was found grow- 

 ing to a good size (18 cm.). There can be no doubt of the dis- 

 tinct specific value of this plant. When it grows in sphagnum 

 bogs, as was found to be the case near Auburn, Ala., a little later 

 in the same season, the plant becomes so spindling and distorted 

 as the result of its struggles in growing through the moss, that it 

 becomes very difficult to recognize it.
