asterisk (*) before the name. Further notes on distribution will 
be found under each species. No asterisk being used an extension 
in range only is indicated. 
Osmunda Claytoniana L. Sphagnous depressions, mesophytic 
woods, Camp Kennedy ; “ Moose yards,” North West Basin. 
* Osmunda cinnamomea L. Growing abundantly on the northern 
shore of the sphagnum bog, Great Basin. 
Aspidtium aculeatum Braunii Doell. Inlet of Chimney Pond, 
half way up to the crest, where it occurred only sparingly. 
* Asplenium Filix-foemina Bernh. Common in mesophytic 
woods of the Great Basin, extending into the North Basin 
and as far as Camp Kennedy in the South Basin; common 
in the North West Basin and along the west slopes of the 
North Spur. 
Pteris aguilina L. Open places, South Basin; common in 
sphagnum bog, Great Basin. 
Lycopodium Selago L. From summit to shores of Lower Basin 
Pond, imperceptibly grading into Z. Jucidulum Michx. Z. 
Selago is apparently a xerophytic form of Z. Zucidu/um, which 
replaces it in more mesophytic habitats. All transitions were 
found varying with the environment. 
* Lycopodium inundatum L. Abundant on the meadow-like 
shores of a small pond in the North West Basin. 
* Lycopodium annotinum L. Common in mesophytic woods, 
South Basin, and in the Arummholz (scrub growth) on the 
table-land. Passes into Z. annotinum pungens Spring, which 
replaces the type in xerophytic habitats. Extends up to West 
Peak. 
Lycopodium Sitchense Rupr. Frequent on floor of North West 
Basin. We are able to record an interesting variation in the 
length of the peduncle of this species. Lloyd and Underwood ! 
in their review of the North American species of this genus 
write in respect to the above species: “peduncles short (less 
than 1 cm.).” One specimen bearing nine strobili gave 
respectively the following measurements of the peduncle : I 
1.,.8, 1., .8,°.2, .3, sessile, and .1 cm. Another specimen from 
a shaded habitat bearing three strobili possessed peduncles of 
1 Bull. Torr. Bot. Club, 27: 162. 1900.
