 1095.) Stem 2-2.5 ( ' in - high. Leaf varying from nearly orbicular to oval. 3-7 cm. 

 long, with I or 2 sheathing scales below it; spike 2-6-flowered ; flowers 12-16 mm. 

 long, subtended by small bracts ; sepals and petals oval, rose-color ; lip white, pur- 

 ple spotted, longer than the petals, 3-lobed, the middle lobe larger, dilated, 2-lobed 

 or notched at the apex; spur slender, shorter than the lip. In damp woods, Green- 

 land to the Rocky Mts., Me., N. Y. and Minn. June-July. 



3. GALEdRCHIS 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. [Compouiid. 

 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.

 them, obovate, sometimes 2 dm. long and 1 dm. wide, but usually smaller, clammy 

 to the touch ; spike 3-6 flowered; flowers about 2-5 cm. long, violet-purple mixed 

 with lighter purple and white; bracts foliaceous, sheathing the ovaries; lip whitish, 

 divergent, entire, about as long as the petals; spur obtuse, about 1.6 cm. long ;

4. PERULARIA Lindl. 



Leafy-stemmed plants, from a cluster of thick fibrous roots. Flowers small, 

 greenish, in a long open spike with long bracts. Sepals and petals broad, spread- 

 ing. Lip lanceolate, with a tooth on each side at the base, and a central tubercle 

 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.]

 sepals greenish yellow ; lip a little longer than the petals ; capsule about 8 mm. 

 long. In moist soil, N. H. to Minn., south to Fla., La. and Mo. June-July. 

 [Habenaria Jlava (L.) Gray.] 



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. 

 [Name Latin, compound, heaven-tongue.] 



1. Coeloglossum bracteatum (Willd.) Pari. Long-bracted Orchis. 

 (I. F. f 1 103.) Stem leafy, 1.5-6 dm. high. Leaves lanceolate, ovate or oval, or 

 the lowest sometimes obovate, 5-12 cm. long, the upper much smaller; bracts 

 longer than the ovaries, the lower ones 2 or 3 times as long ; spike 7-12 cm. long,
