Cayman l.rae, I'-ahamas, Cuba, 1 tispaniola, Porto Rico, Trinidad, Colombia, 

 Brazil. 



Plant L5 18 in. high. Stem somewhat stout, downy above, glabrous 



below, 3 dm. and over. Leaves 1 or 2, oval, acute, blade 11-15 em. 1., 

 3-5 cm. br. ; stalks 12-18 cm. 1. Sheaths 1 or 2, radical, below the leaves, 

 scarious, 2-5 cm. 1. ; caulinc tubular below, free part triangular, acuminate, 

 2 '< em. 1. Spike downy, lax, with several llowers, 3-15 cm. 1. Bracts 

 ovate, apex acuminate, awn-like, 5-nerved, longer than the o\ary, 

 2-2'5 cm. 1., abcut -5 cm. br. Ovary spindle-shaped (with stalk) 2 cm. 1. 

 Floivers greenish-white. Sepals linear-lanceolate, 7-nerved below (from 

 point of attachment at base of column) 2*8 cm. 1., barely 2 mm. br., 

 median 2 5 mm. br. ; spur tapering, obtuse. Petals similar to sepals, 

 attached throughout their length to the median sepal, nearly 2 cm. 1., 

 1*4 mm. br. Lip white, many-nerved. Column (below stigma) 3 mm. 1., 

 from base of column to apex of anther 9 mm. 1. Capsule broadly 

 ellipsoidal, with six shallow keels, dehiscing at some little distance below 

 the apex, 2 cm. 1., 8 mm. br. 



Var. glabra Cogn. is based on Harris Fl. Jam. 7863, the author says 

 " scapus usque ad apicem glaberrimus," but all the specimens which we 

 have seen bear the usual pubescence.

5. STENORRHYNCOS Spren 



Terrestrial herbs, root fibres generally fleshy, clustered, with 

 radical leaves, or flowering sterns leafless. Leaves elliptical to 

 ligulate, radical, tapering at base into long stalks which are 

 flattish, concave, sheathing at base. Flowers medium size to 

 small, in a spike. Sepals free, subequal ; median erect, cohering 

 with the petals ; lateral obliquely affixed at the apex of the 

 ovary, and decurrent with the column, produced at the base into 

 a chin or distinct spur, erect. Lip sessile or clawed, erect, con- 

 cave, embracing the column and sometimes adherent to it, 

 spreading at the apex, entire or indistinctly 3-lobed, without 

 calli. Column terete, at the base with a long foot ; stigma broad 

 under the erect, long rostellum ; clinandrium posteriorly short, 

 margins sometimes raised and continuous with the rostellum. 

 Anther erect, oblong-lanceolate, 2-celled ; pollinia powdery-granu- 

 lar, pendulous from a gland of the rostellum. Capsule obovoid 

 or ellipsoidal, 3-keeled. 



Species about 25, natives of tropical America. 



Leaves, several, elliptical 1. S. speciosus. 



Leaves, 1 or 2, or wanting during flowering season. 

 Plant with glandular-pubescent hairs. Perianth 



J- in. 1. Spur about J length of ovary 2. S. lanceolatus. 



Plant scurfy with white scales. Perianth 1-1^ 



in. 1. Spur about length of ovary 3. S. squamulosus. 



1. S. speeiosus Lindl. Gen. & Sp. Orch. ill (1840); plant 

 glabrous ; leaves several, elliptical ; bracts crimson or rosy-pink, 

 elliptical, acuminate, nerves 3, lateral branching, nearly as long- 

 as or longer than the flower ; perianth crimson or rosy-pink,
