OECHIDACEAE. 57 



21. ANACHEILIUM Hoffmg. Epiphytic herbs with elongate flattened 

 pseudobulbs which 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.) Hoffmg. 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 conns. Leaves 

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

 Flowers in 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. multiflorum. 



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



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



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



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

 scape 2-4 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, 6-8 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 E. & P. Caulescent herbs with corms. Leaves several 

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

 arises. Eaceme 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
