ORCHIDACEAE. 57 



21. ANACHEILIUM llolinig. Epijihytic herbs with elongate flattened 

 pseudobulbs wliich bear several elongate erect leaves and a simple flowering 

 stem at the apex. Flowers nodding, subtended by often lanceolate bracts. 

 Perianth usually showy. Lateral sepals narrow and elongate, usually attenu- 

 ate, resembling the median one. Petals usually slightly shorter than the 

 sepals. Lip much shorter than the sepals and petals; blade very broad, 

 clamshell-like, entire. Column partly adnate to the lip. Capsules drooping, 

 wing-angled. 



1. A. cochleatum (L.) Iloffmg. Plants 2-5 dm. tall; leaf -blades linear or 

 nearly so, 1.5-4 dm. long: flower-stem simple: lateral sepals 25-30 mm. long, 

 linear-lanceolate and attenuate: lip brown or purplish; blade orbicular-reni- 

 form, 16-20 mm. long, entire, abruptly pointed : capsule-body 20-30 mm. 

 long. [Epidendrum cochleatum L.] — Hammocks. — F. K. (Bah., Cuba, Ant.) 



22. LIMODORUM [Gronov.] L. Scapose herbs with corms. Leaves 

 few, consisting of several sheathing scales, except one with an elongate blade. 

 Flowers iti a terminal raceme-like spike. Perianth mainly purple, pink- 

 purple or white. Lateral sepals inequilateral, shorter than the median one. 

 Petals nearly equilateral, somewhat narrowed at the base. Lip with 2 

 minute lateral lobes, and a dilated middle lobe bearded with clavate hairs. 

 — Grass-pink. 



Dilated portion of the middle lobe of the lip narrowed down to the lateral lobes. 



Lateral sepals broadly ovate : crest of the lip extending to the margins. 



1. L. miilti/loyinn. 



Lateral sepals oblong-ovate: crest of the lip central. 2. h. pinetorum. 



Dilated portion of the middle lobe of the lip separated from the 



lateral lobes by a linear stalk-like base. 3. L. Simpsonii. 



1. Ii. multiflomm (Lindl.) C. Mohr. Leaf -blades linear, 8-15 cm. long: 

 scape 2— i dm. tall: perianth deep-purple: lateral sepals ovate, 10-12 mm. 

 long, acute: petals 12-13 mm. long, the blades ovate or obovate: middle lobe 

 of the lip broadly cuneate, 8-9 mm. wide, truncate and mucronate: column- 

 wings rhombic. — Everglades. 



2. L. pinetorum Small. Leaf -blades narrowly linear, 0.5-1.5 dm. long: scape 

 1-2.5 dm. tall: perianth deep-rose: lateral sepals oblong-ovate, 10.5-11.5 mm. 

 long, acutish: petals 11-12 mm. long, the blade oblong: middle lobe of the 

 lip cuneate, 0-8 mm. wide, nearly truncate at the apex and mucronate: 

 column-wings half-orbicular.^ — Pinelands. 



3. L. Simpsonii Small. Leaf-blade narrowly linear, 30-40 cm. long: scape 

 5-9 dm. tall: perianth purple or rarely white: lateral sepals half-orbicular, 

 17-18 mm. long^ cuspidate: petals 20-22 mm. long, the blade oblong-ovate: 

 middle lobe of the lip 8-10 mm. wide, obreniform, emarginate, mostly over 11 

 mm. wide: column-wings broadly obovate. — Everglades. — (Bah., Cuba.) 



23. BLETIA R. & P. Caulescent herbs with corms. Leaves several 

 from the top of the corni, mostly persisting until after the lateral flower-stem 

 arises. Raceme loosely flowered. Perianth mainly pink or purplish. Lateral 

 sepals slightly inequilateral. Petals nearly or quite similar to the lateral 

 sepals. Lip wide, crested, 3-lobed, the middle lobe crisped. Capsules mostly 

 erect. 



1. B. purpurea (Lam.) DC. Leaf-blades broadly linear to linear-elliptic, 

 1.5-3.5 dm. long, attenuate: flower-stem 3-11 dm. tall: lateral sepals oblong- 

 ovate to broadly oblong. 11-16 mm. long, abruptly acuminate: petals oval 

 or ovate-oval, barely as long as the sepals; lip 11-15 mm. long, with a broad
