mens of this plant. The stations known show that it encircles 

 Canada, and some of them are probably within our limits. Prin. 

 cipal Dawson obtained the alpine variety on the White Mountains, 

 Herb. Bot. Soc. Canada, It is a rare plant in the United States. 

 There are two forms of this species (both of which are figured by 

 Dillenius) : a. sj/haficus, leaves convergent, almost appressed; /3. 

 aljnnus, leaves widely-spreading, stems shorter. 



P. lucididus. Stem dichotomously divided into long erect 

 branches; leaves bright green, in about 8 rows, reflexed, linear- 

 lanceolate, acute, denticulate ; sporangia in the axils of the com- 

 mon leaves (not in spikes). Lj/coj^ocUum lucididum, MichauXj

 mon in New York State. " Frequently bears bulbs instead of 

 capsules," Pursh. 



\_P. alocuperoides, P. Beauv. — The habitat " Canada" is given 

 for Lycopodium alocuperoides, Linn., in the " Species Plantarum," 

 ed. 3, vol. ii, p. 1565; but it is probably not a Canadian plant.] 



P. inundatus, P. Beauv. Stems prostrate, adherent to the soil, 

 the fertile ones erect ? leaves secund, yellowish-green, lance-awl- 

 shaped, acute ; sporangia in distinct, terminal, leafy, sessile, solitary 

 spikes. Lycopodium inundatum, Linn., E. B., Michaux, Pursh, 

 Beck, Tuckerman, Torr. Fl. N. Y. ii, p. 508, Gray. Planantlius 

 inundatus, Beauv. L. alocuperoides, Linn., in part ? — In cedar 

 swamps and overflowed woods, Canada, Pursh. Professor Torrey 

 notices its occurrence in the north-western part of the State of 

 New York. Professor Gray observes, that the leaves are narrower 

 in the American than in the European plant, and suggests that it 

 may be a distinct species. I have not yet seen Canadian specimens. 



Lycopodium. 



L. clavatum, Linn. — Stems robust, and very long, prostrate, 

 rooting, forked, with short ascending branches; leaves pale, in-
