Linn., is a small-flowered species with no spurs at the base of 

 the perianth, and a much shorter tail, it is a native of 

 Hispaniola, and, as above stated, has never been in cultivation 

 in so far as I know. 



Aristolochia trilobata has an extended distribution, from 

 Jamaica and many other West Indian Islands to Guiana, 

 and to Bahia in Brazil, and as with so many other species of 

 the genus, is said to be used by the negroes as a cure for 

 snake bites. The drawing was kindly executed by Miss E. 

 A. Ormerod, from a plant which flowered at Kew in July. 



Desce. A very slender climber, with glabrous almost 

 filiform branches, and scattered leaves of a bronze-green 

 colour. Leaves very variable, very broadly ovate, orreniform- 

 ovate, or orbicular in outline, two to four inches in diameter, 

 more or less three-lobed, sometimes more than half way down, 

 with obtuse, erect or spreading lobes, and rounded sinus be- 

 tween them, glabrous above, beneath clothed with a very 

 firm pubescence ; base truncate, rounded or cordate J nerves 

 spreading from the tip of the petiole finely reticulate ; petiole 

 slender, about as long as the blade or shorter, often tortuous ; 

 stipular leaf orbicular, with re volute margins. Flowers pale 

 dull green, mottled with brown, the terminal lobe and tail 

 deep brown. Peduncle and very slender ovary together 

 three to four inches long. Perianth variable in size ; basal 

 part oblong, one to two inches long, inflated, suddenly con- 

 tracted at the base, and there furnished with six reflexed 

 obtuse elongated conical spurs ; tubular part as long as the 

 basal or longer, sharply reflexed upon its cylindrical, with 

 a circular expanded hairy mouth ; bristly and spotted within 

 with dark purple ; lips reflexed ; terminal lobe (like the oper- 

 culum of a Nepenthes), curved over the mouth of the tube, 

 broadly ovate with reflected sides, suddenly contracted into a 

 twisted very slender tail about twice the length of the rest 

 of the perianth. Anthers six to eight, united with the styles into 

 a tubular eight-cleft cup with acute lobes. Capsule large, cylin- 

 dric, two to four inches long.
