78 Rhodora [May 
Corallorrhiza trifida Chatelain was growing in quite a colony under 
hemlocks. 
Microstylis unifolia (Michx.) BSP., only two specimens found. 
Smilacina trifolia (L.) Desf. There are rather large areas of this 
surrounding the little pools. It is one of the swamp plants that seems 
to have increased since we first collected it here. 
Clintonia borealis (Ait.) Raf. flourishes here. 
Calla palustris L. covers one section of the brook. 
Arisaema triphyllum (L.) Schott. In a very shady wet place, quite 
a colony of plants showed peculiarities that suggested its close rela- 
tion to A. Dracontium. Each plant was quite strict in growth, the 
spathe slender and more erect at the summit than is usual in the type. 
The leaves were five-parted. 
Solidago Elliottii T. & G. Two or three ie were growing in a 
rather open wet place. 
Utricularia clandestina Nutt. completely filled one of the little 
pools to the exclusion of all other growths. Not a trace of the plant 
could be found in any of the near-by pools. 
Nemopanthus mucronata (L.) Trel., lover of cold shady swamps, 
finds a congenial home here, and adds to the overhead tangle. 
Sarracenia purpurea L. has been reported from this region, but we 
have not found it. 
Carex subulata Michx. we suppose may, from the botanist’s stand- 
point, be called the chief treasure of the swamp. It seems to be 
quite abundant here and we might wonder why it should be so rare 
when its facility in fastening its mature seeds on the clothing can be 
so well demonstrated by lightly brushing past a clump of it. 
Stellaria borealis Bigel. grows in masses in and near the brook. 
So much for the deepest part of the swamp. As we push through 
the bewildering tangle and come to the foot of the knoll, once inhabited 
by the pines, we find a profusion of 
Lygodium palmatum (Bernh.) Sw. twining over the weeds and bushes 
and even clothing some of the old stumps with its delicate beauty. 
This fern has increased very much in the past years. 
Aspidium simulatum Davenp. has been collected here by Messrs. 
Bigelow and Bissell, and is reported as quite abundant in some parts 
of the bog. 
Linnaea borealis L. var. americana (Forbes) Rehder formed a thick 
mat over the roots of one of the old pine stumps. This was our great-
