and sheathing bases, the lower portion of the stem often merely scaly and 

 sometimes thickened after the manner of an elongate pseudobulb. Flowers 

 in a terminal open or contracted raceme or panicle, usuallj' long-pedicelled. 

 Perianth rather large, often showy. Lateral sepals obtuse, acute, or attenuate, 

 often elongate. Petals spatulate or slender and attenuate. Lip relatively 

 large, entire or fimbriate, the middle lobe, wanting, minute or elongate. 

 Column elongate, wholly adnate to the lip-base. Capsules drooping. 



Lip with 2 latfiral lobes directed forward and an elongate slender middle lobe : 

 petals slenderly attenuate : lateral sepals narrow. 1. A. nocturna. 



Lip with 2 broad spreading lateral lobes and a broad short notched 



middle lobe : petals spatulate : lateral sepals broad. 2. A. difformis. 



1. A. nocturna (L.) Small. Plants 3-11 dm. tall: leaf -blades oblong to 

 broadly linear, 8-16 cm. long: j^erianth showy: lateral sepals linear-attenuate, 

 40-60 mm. long, green: petals narrower than the sepals: lip white; blade with 

 2 ovate or oblong-ovate lateral lobes directed forward and a linear-setaceous 

 middle lobe 3.5-50 mm. long: capsule-body 3-5 cm. long. [Epidendrum noc- 

 turnum L.] — Hammocks. — {Bah., Cuba, Ant.) 



2. A. diflformis (Jaccj.) Small. Plants 1-3.5 dm. tall: leaf -blades oblong or 

 nearly so, 4-8 cm. long: perianth green: lateral sepals more or less oblique, 

 sometimes broadly simitar-shaped, 12-15 mm. long : lip green ; blade 7-8 mm. 

 long, reniform to orbicular-reniform, with broad rounded lateral lobes and a 

 short notched middle lobe: capsule-body 13-16 mm. long. [Epidendrum 

 difforme Jacq.] — Hammocks. — (Cuba, Ant.) 



19. 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 

 reniform-orbicular : capsule-body 25-30 mm. long. [Epidendrum tampeiise 

 Lindl.] — Hammocks. — F. K. 



20. 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 liroadonod u])ward : petals 

 l>roadly spatulate, brown-si>otteil like the sei)als: lip yellow or mainly so; 

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

 25-30 mm. long. [Epidendrum Boothianum Lindl.] — Hammocks. — F. K. (Bah., 

 Cuba.)
