Appendix 253 



Flowers white, small, in a densely flowered spike 2-10 inches 

 long. Slightly fragrant. Not constructed for self-fertilization 

 as the closely allied species H. hyperborea. Labellum entire, 

 dilated, or obtusely 3-lobed at base. Spur blunt and incurved. 

 Sepals ovate, obtuse, and small. Stem slender, often stout, 

 inferring that an intermediate form exists, which Dr. Rydberg 

 has designated specifically as fragrans. Leaves lanceolate. 

 Seed-capsule much twisted.

8.— HABENARIA FRAGRANS (Rydberg) Niles, 1901-1903 ' 



Fragrant Slender Bog-Orchis 



The specific na.m^^ fragrans, refers to the exquisite fragrance 

 of this species, which is so closely allied with H. dilatata and 

 of which it appears to be a form. 



Slender bogland orchid, with fleshy-fibrous roots. July. 



Flowers small, pure white, very fragrant ; in a slender 

 spiked raceme. Labellum narrowly linear, dilated at the base, 

 obtuse, shorter than the curved filiform spur ; otherwise as the 

 preceding species. Sepals lanceolate, acutish, strongly striate. 

 Stem very slender and leafy above, 8-12 inches high. Leaves 

 linear, several. 



Continental 7?aw^<?— Reported from a single station in Ver- 

 mont. Slender forms of//, dilatata, very fragrant and slightly 

 so, are present in the bogs of Pownal, Vermont, and North 

 Adams, Massachusetts, where the writer has collected them, 

 believing that they were forms brought about by the inter- 

 grading of the bogland Habenarias closely associated. Species 

 oi Ha ben aria appear to produce natural hybrids readily.* 



New England Range— Vermont. 



' Doubtfully reported for Hoosac Valley region, although 

 native of Vermont.
