3. SMALL NORTHERN BOG ORCHIS 



Hahenaria ohtusata (Pursh) Richards. (Plate XV.) 



Side by side with the two more striking round-leaved 

 orchis comes one related to them in structure, but so 

 different in appearance and habitat as to appear a very 

 distant relation. It is a tiny green and white plant, com- 

 monly known as the Dwarf Orchis, growing in cold, wet, 

 mountainous places. It is found in the Green Mountains 

 from the last of June on through July, and in the White 

 Mountains as late as August. Although it is not very 

 common, yet it is found growing in wet places throu^out 

 the states north of Lake Superior, and also in Colorado. 



The accompanying illustrations are so full in the en- 

 largement of their detail that they give but a faint idea 

 how tiny the flower is. The. whole plant is but a few, at 

 most ten, inches high. The single basal leaf is often not 

 more than two, never more than five, inches in length, and 

 barely an inch wide. The loose-flowered spike is from one 

 to two and a half inches long and the flowers do not measure 

 half an inch, and yet the arrangement for the reception of 

 insects is peculiarly careful, and the wide distribution of 

 the orchid along the wet places of the Northern States shows 

 that it has not suffered extermination for lack of fertilisation.
