Peramium tesselatum, Loddiges 

 The leaves are dark green, mottled with white or light 

 green, very variable. This rattlesnake plantain is distribu- 

 ted in the mixed forests over the north of Maine, New Bruns- 

 wick and Quebec. Flowers in July and August. 



Peramium Menziessi, Lind., P. dicipienSf Hook 



The largest of the rattlesnake plantains. The leaves 

 are dark, mottled with light green along the center, from two 

 to three and one-half inches long. Stem, 10 to 12 inches 

 and spike of sweet-scented flowers, two to four inches. I 

 have found two large patches with about 235 plants in New 

 Sweden, near the Capitol, 1904. In Perham I have found it 

 in four different places and about 300 plants, and a few sin- 

 gle plants in Woodland, habitat near the top of hills in 

 mixed forests of spruce, hemlock and some hardwood. In 

 Quebec, on Mt. Wissick, Temiscouata Lake, in August, 1913, 

 I observed a number of these plants, but they were smaller 

 than those I have found in Aroostook County. All the rattle- 

 snake plants were common on Mt. Wissick. They are in 

 flower in July and August. 



THE GREEN ADDER'S-MOUTH 



Malaxis unifolia, Michaux 



1 have only observed this plant in Perham in the north 

 and central part of the town. Flowers from July 10 to Aug- 

 ust 10. The height of the largest plant I have is 7 1-2 inches, 

 and one of the plants collected has two leaves on the center 

 of stem. The flowers are minute and very numerous and 

 have to be studied under the microscope. 



CALYPSO 



Cytherea bulbosa, Linne 



Among botanists, C. bulbosa is considered one of the 

 most beautiful and rare plants. Sometimes I find a good 

 number of these plants in the cedar swamps on the head- 

 waters of Caribou stream in New Sweden, Woodland and 

 Perham. Among the orchids it is the first one to open and 

 I have collected it the first week in May, or as soon as the 

 snow is off the ground, on my farm in Woodland in full 

 bloom; and I have sometimes found flowers the first week 

 in July. This is the most enduring fiower I have seen. 

 Sometimes I have had them standing in a little damp moss 

 in my room for three weeks before they have begun to 

 wither, and any ordinary frost, common with us in May and 

 June, seems to have no effect on them.
