ORCHrDACEAE. 37 



Anther-sacs with filiform appendages at the base. Stigma with a short 

 appendage, the glands naked. 



1. H. Garberi (Porter) Small. Stems 3-6 dm. tall: leaf -blades oblong to 

 oblong-lanceolate, 6-10 cm. long: lateral sepals very broad, 5.5-6.5 mm. long: 

 petals about 4 mm. long, sinuately 3-lobed at the apex: lip 6-10 mm. long, 

 broadly linear, obtuse: spur 12-18 mm. long: capsule-body 10-15 mm. long. — 

 Hammocks, U. keys. — [E. K.] — (Cuba.) 



3. PHYSURUS L. C. Rich. Caulescent succulent herbs, the stems leafy. 

 Leaves with wide blades. Spike compact. Perianth whitish or greenish. 

 Lateral sepals relatively broad, decurrent, together with the base of the lip, 

 as a sac partially adnate to the hypanthium. Petals mostly smaller than the 

 sepals. Lip 3-lobed. the terminal lobe quite as long as the body of the lateral 

 lobes, with a reflexed tip, the broad claw-like base forming part of the spur. 



1. P. querciticola Lindl. Plant 1-3 dm. tall: leaf -blades lanceolate to ovate, 

 1-6 cm. long: lateral sepals 4-4.5 mm. long: petals 3.5-4 mm. long, narrower 

 than the sepals, inequilateral. — Hammocks, Big Pine Key. — [E. K.] — (Bah., 

 Cuba, Ant.) 



4. ENCYCLIA Hook. Epiphytic herbs with terete pseudobulbs which 

 bear several erect or arching elongate leaves and a scaly elongate branched 

 flowering stem at the apex. Flowers nodding, subtended by small bracts. 

 Perianth often conspicuous. Lateral sepals rather broad, usually about as 

 wide as the median one. Petals usually of a spatulate type. Lip 3-lobed, the 

 middle lobe much broader than the lateral ones. Column slightly adnate to 

 the lip. Capsules drooping, ribbed. 



1. E. tampense (Lindl.) Small. Plants 1.5-6 dm. tall: leaf -blades linear to 

 narrowly linear-lanceolate, 8-20 cm. long: flower-stem typically branched: 

 lateral sepals 17-20 mm. long, slightly broadened upward: petals spatulate, 

 deeper brown-shaded than the sepals: lip white and rose-purple; blade 15-17 

 mm. long, the lateral lobes oblong-lanceolate, the middle lobe orbicular or 

 renif orni-orbicular : capsule-body 25-30 mm. long. — Hammocks, U. keys, L. 

 keys.— [E. K.] 



5. EPICLADIUM Small. Epiphytic herbs with short flattened pseudo- 

 bulbs which bear several short erect leaves and a relatively short mostly 

 simple flowering stem which is subtended by a long foliaceous spathe. 

 Flowers erect or ascending, subtended by minute bracts. Perianth showy. 

 Lateral sepals rather short, about as wide as the median one. Petals nearly 

 resembling the lateral sepals or more dilated upward. Lip shorter than the 

 sepals and petals, the blade usually rhombic. Column partly adnate to the 

 lip. Capsules nodding, winged. 



1. E. Boothianum (Lindl.) Small. Plants 1-2 dm. tall, with flattened subor- 

 bicular pseudobulbs: leaf -blades spatulate, 6-12 cm. long: flower-stem simple: 

 lateral sepals 11-13 mm. long, elliptic or slightly broadened, upward: petals 

 broadly spatulate, brown-spotted like the sepals: lip yellow or mainly so; 

 blade rhombic, 4-6 mm. long, the broad lateral lobes spreading; capsule-body 

 25-30 mm. long. — Hammocks, Key Largo. — [E. K.] — (Bah., Cuba.) 



6. AJSTACHEIIilUM Hoffmg. Epiphytic herbs with elongate flattened 

 pseudobulbs which bear several elongate erect leaves and a simple flowering
