2() Rhodora [January 



of August. Lust summer it was especially common owing probably 

 to the rainy season. To those accustomed to regard P. opkioglotaoidet 

 as the typical representative of the genus, P. trionthophora has an 

 unexpected habitat growing only in fallen leaves, the bulbous base 

 and roots lying loose among the fallen leaves and not fixed in the 

 ground. Utricularia resupinata appears to be a rare plant. I found 

 it only once in small numbers in sand with Gratiola just below the dam 

 at the foot of Lake Chocorua, This appears to be the locality where 

 it was collected by Dr. ( '. \Y. Swan, Aug. L888, according to a specimen 

 in the herbarium of the N. E. Hot. Club. In the rapidly Mowing water 

 close by grows the rare alga, Hormoapora purpurea Wolle, a species 

 whose position is still doubtful. 



The maritime Hudsonia tomentosa 1 have never found at Chocorua 

 but it is rather common on the west shore of Lake Ossipee close to the 

 cottages of the summer camp growing with Pruuus vuueuitt and a 

 Solidago which Prof. Eernald informs me is the maritime S. tcnuifolia 

 and not the S. graminifolia common by roadsides in the region. The 

 strand flora of the numerous small lakes in and about Chocorua differ 

 in some interesting respects from that of Lake Ossipee and some of 

 the lakes, as Lovell's Pond in Fryeburg, which lie to the northeast. 

 It seems to me that an interesting trip would be to follow the chain of 

 lakes extending from ( 'onway and Fryeburg to the Kezar Ponds farther 

 north but 1 have never had the time to explore that region. 



The fern-flora of Chocorua, contrary to the statements of summer 

 visitors, is poor and uninteresting if we except the OphiogloBsaceae. 

 1 found a considerable quantity of Opkiogloseum rulgatum in the 

 meadow opposite the Hotel, Botrychium lanceolatum and B. ramosum 

 are not uncommon and B. obliquum in several varieties and B. ierna- 

 tuiu are very common, the latter more luxuriant than I have ever 

 seen it elsewhere. With the exception perhaps of Sarracenia no plants 

 have so astonished different foreign botanists, who have visited 

 Chocorua, as the abundance of the different species of Lycopodium. 

 We who have always seen them have become more or less indifferent 

 to them but there is probably no place in the world where the northern 

 temperate Lycopodia can be better seen than in the region of Chocorua 

 where even the European species are more abundant than in Europe 

 except in rare localities. Isoetcs Tucker maiii is common in several 

 places in Lake Chocorua.
