3. GALE6RCHIS Rydb. 



Rootstock very short ; root of numerous fleshy fibres. Stem scape-like, with 2 

 large rounded leaves at the base. Flowers in a short loose spike with large leaf- 

 like bracts surpassing them. Sepals united above, forming a kind of galea, or 

 hood. Petals connivent, somewhat adnate to the sepals. Lip entire, wavy, pro- 

 duced below into a spur. Column short, scarcely extending beyond the base of the 

 lip. Anthers 2-celled, the sacs divergent ; pollinia granulose, i large mass in each 

 sac, produced into a slender caudicle. Glands enclosed in a pouch. [Compound 

 word of which the first part refers to the hood-like united sepals.] 



A monotypic genus, native of North America. It was established by Rafinesque 

 in 1836, under the name Galearis, which is antedated by Galearia Presl, of 1830.

4. PERULARIA Lindl.

 at the middle of the base. Spur slender, straight, longer than the lip. but shorter 

 than the ovary. Valves of the anthers horizontal, opening upward, dilated at the 

 base so as to form an oblong cavity, enclosing the orbicular incurved gland. Pol- 

 inia granulose, produced at the base into a caudicle. A genus of 2 or 3 boreal, 

 nearly related species, often included in Habenaria. [Latin, a little wallet.]

5. COELOGLOSSUM Hartman. 



Leafy plants, with biennial 2-cleft tubers. Flowers greenish in a long leafy- 

 bracted spike. Sepals free, somewhat arcuate, bent together and forming a hood. 

 Petals narrow. Lip oblong, obtuse, 2-3-toothed at the apex. Spur much shorter 

 than the lip, blunt, sac- like. Column short. Pollinia with long caudicles. 

 Glands small, scarcely wider than the caudicle, surrounded by a thin membrane. 

 A boreal genus of 2 or 3 species, often included in Habenaria or Platanthera.
