v. s. in herb. Hook. ( Appun. 869, in flore, snb Hippocratea malpighiefolia) ; in herb. 
Mus. Brit. et Hook., Berbice (Schomb. 352); in herb. Hook., San Vincente 
(Guilding). 
This plant was erroneously referred to Hippocratea integrifolia by Dr. Seemann, at 
the same time that he confounded it with two other species of this genus; it was also 
wrongly considered by Dr. Grisebach to be identical with Hippocratea malpighiæfolia, 
Rudge. Schomberg states that it is “a ligneous twiner, with white flowers, which, 
however, become yellowish in drying. It has slender branchlets, divaricating at right 
angles, with axils 1-12 in. apart: the leaves, sometimes large, are 3-77 in. long, 13-32 
in. broad, on a petiole 3-6 lines long; they have the same peculiar dull apple-green 
colour, with fine raised reticulations, which peculiarly distinguish all the species of this 
genus, with the cartilaginous basal margins always continuous with the raised rim of the 
petiole. The axillary panicles are 3 in. long, on a peduncle 1-13 in., the primary sub- 
alternate branchlets 9 lines, the secondary 5 lines, the tertiary short, terminated by a 
single flower, on a pedicel 2-3 lines long; sometimes by the fall of the superior leayes, 
the compound inflorescence assumes the appearance of a large terminal corymb, 6-7 in. 
long, 34-6} in. broad; the branches are all very slender; the flower expanded is 6-8 
lines in diameter; the sepals, with broad membranaceous margins, are 1 line long, À line 
broad; the petals, 33—4 lines long, 13-2 lines broad, are extremely membranaceous, and 
of a pale bright yellow colour.
