material. 



The paper of the evening was by Professor F. E. Lloyd, 



" Studies in the genus Lycopodimny Professor Lloyd discussed 

 the distinguishing characters of the North American species, with 

 reference to structure and habit. Two new species were recognized 

 in this review of the genus. One group of species is remarkable 

 for greater variation here than in Europe, producing five species 

 here and one there; including here L. inundatiim and its var. 

 Bigelovii, L, adpressum, L. alopecitroides and L. pinnatitm. The 

 type-specimen of L. pinnatuin of this group was exhibited. These 

 species develop toward the close of the season a strong, starchy 

 thickening of the growing end of the stem. This serves as a basis 

 of growth the next spring. Professor Lloyd also restored the 

 long -forgotten species L. Sitchense, which has 5 rows of leaves, 

 but has been confused with the 4-rowed species, L. sabinaefoliiim. 

 Dr. Underwood followed, remarking on the general distribu- 

 tion of Lycopoduun, about 94 species or perhaps properly about 

 120; of which 1 2 are North American ; perhaps 2 1 are peculiar 

 to the Andes, and with them grow many others which extend into 

 Mexico or Guiana ; about 8 are peculiar to Madagascar, 4 to 



India, etc.; mostly in mountain regions. L. cernitum probably en- 

 circles the world in the tropics. The local distribution along 

 Atlantic America is peculiar, L. alopecuroides, reported from New 

 England, cannot be traced by accessible specimens north of Long 

 Island. The sprawling and arching habit of this species with 



spongy interior and caterpillar-like or foxtail-like exterior gives it 

 a very peculiar effect. Dr. Underwood also described his discov- 

 eries of L. porophilum in Kentucky, Wisconsin, Alabama, etc. 



The Secretary raised the question of the distribution of L. 

 annotinnm, which is present in the Adirondacks, Catskills and
