On shrubs and trees, growing on limestone rocks ; in fl. and f r. June ; 

 Angels, near Spanish Town, and on hills near, Sloane Herb. vii. 86 ! in 

 very dry, calcareous mountainous places, Swartz ! Retirement, St. 

 Elizabeth, J. P. 460, Morris ! Stony Hill, J. P. 460 (2613) Symel Constant 

 Spring 650 ft., Stony Hill, 900 it.," Harris ! Fl. Jam. 5827, 10,411 (Marchl 

 in Hb. Kew. ; owing to the unsatisfactory condition of the flower, which 

 has apparently a glabrous lip, we have had some hesitation in referring it 

 to this species). Cuba, Hispaniola, Porto Rico, St. Thomas, Bahamas. 



Stem leafless on main stem, thick, 1 cm. or more br., shrivelling very 

 much, to 5 or 6 mm., when dry; internodes about 10 cm. 1. ; adventitious 

 roots often twisting spirally like tendrils. Leaves 3-8 cm. 1. Raceme with 

 8-12 sessile flowers, to 14 cm. 1. Bracts below like the leaves, but much 

 smaller, above triangular, acuminate, 2-* 5 cm. 1. Ovary as long as the 

 sepals, cylindrical. Floivers fragrant, glaucous green sepals with a white 

 and purplish lip, perianth nearly 2 ins. 1., crowded towards apex of raceme. 

 Sepals narrowly elliptical, obtuse, 4-4*7 cm. 1., 1-1 - 1 cm. br. Petals as 

 long as sepals, keeled, 1*3 cm. br. Lip roundish, crenate and curled on 

 upper margin, attached to column for two-thirds its length, with ramen- 

 taceous hairs inside along the central line, and at the sides below, 5 cm. 1., 

 about 4*5 cm. br. when flattened out. Column 3 cm. 1. Capsule ellip- 

 soidal-cylindrical, thickest in the upper part, narrowing gradually to the 

 base, 10 cm. 1., 1*6 cm. br. 



Swartz says, " flores albi . . . odor fortis Orchidearum." Grisebach 

 quotes Wright as saying "perigonium rufescenti-virens, labello rubro- 

 marginato et punctato, mediano intus barbato." We have not taken the 

 species name from Linnaeus's Cactus parasiticus owing to the great 

 confusion in his references. In the Systema (1759) he describes C. 

 parasiticus as "repens, teres, striatus, muticus," referring to (1) Sloan. 

 Jam. 224, f. 3, 4, the specimen of which is in Herb. Sloane, and is 

 Vanilla claviculata Sw. ; (2) Plum. Ic. 197, f. 2, probably a species of 

 Rliipsalis. In Species Plantarum, ed. 2, i. 668 (1762) he repeats the 

 diagnosis from the Systema, but drops the reference to Sloane, citing instead 

 Cactus parasiticus inermis etc. Browne Jam. 238. In the Linnean 

 Herbarium there is a specimen from Browne named Cactus parasiticus by 

 Linnaeus; this has no flower, and is either Dendrophylax funalis, or a 

 leafless species of Campylocentrum. 



2. V. inodora Schiede in Linnsea iv. 574 (1829); leaves 

 much longer than the internodes, elliptical, shortly acuminate, 

 membranous, very shortly stalked ; bracts in two ranks, foliaceous, 

 membranous, like the leaves but much reduced and varying in 

 size. Bolfe op. cit. 449 ; Cogn. op. cit. 320. Vanilla flore viride 

 et albo, fructu nigrescente, Plum. Nov. Gen. PL Amer. 25, t. 28
