bright yellow, slipper-shaped flowers, blooming through June, July, 

 to the middle of August. I have collected this species in Stockholm, 

 New Sweden, Woodland, Perham, Caribou, Fort Fairfield, Marshall, 

 Castle Hill, Chapman Plantation and Crystal. 



Ram's Head Lady's Slipper. 

 (Criosanthes arietum R. Brown.) 

 A very rare and local plant. I have never seen this Lady's Slip- 

 per, but it is liable to be found in some Aroostook bog. 



Moccasin Flower ; Stemless Lady's Slipper. 

 (Fissipes acaulis Alton) 



This plant has a wide distribution in Maine. It is mostly found in 

 spruce and hemlock forests. A plant with two large leaves near 

 the ground and stem from six to sixteen inches, with one large 

 Moccasin-like flower, white, sometimes pink or rose purple. May 

 30th to June 20th. I have a plant collected in Westmanland Plan- 

 tation June 13, 1918, with two large, white flowers on the same stem. 

 This is a very rare occurrence, as the textbooks do not mention it. 



I have collected these orchids in New Sweden, Woodland, West- 

 manland and Perham, Aroostook County ; in the forest between 

 Patten and Matagoman Lake, Penobscot County ; and Misry Town- 

 ship, Somerset County. 



Small Round-Leaved Orchis 



(Orchis rotundifolia Pursh) 



This is one of the rarest plants in the United States. I have found 

 this Orchis in a cedar swamp in Woodland, at Salmon Brook Lake 

 in Perham and at Han ford Siding, Perham. 



Stem eight to ten inches, with a single oval or orbicular leaf near 

 the base and a spike of four to sixteen white flowers with purple 

 blue spots. In bloom from June 14th to July 10th. 



Showy Orchis. 

 (Galeorchis spectahilis Linne) 

 I have not seen this plant in Northern Maine, but my friend, F. C. 

 Merritt, has collected it at Dover in Piscataquis County.
