MR. J. MIERS ON THE HIPPOCRATEACEA OF SOUTH AMERICA. 357 
saw mixed with the typical plants, and which belongs to Hippocratea levigata, Rich. ; 
Rudge's description, however, accords well with the type. 
Dr. Grisebach (Fl. Br. W. Ind. 148) gives a description, full of inaccuracies, being 
a medley of characters of different plants which have no relation with this species, appa- 
rently unknown to him; he quotes as its synonyms Hippocratea integrifolia, Rich., Ton- 
sella malpighiæfolia, Meyer (Tontelea longifolia, nob.), Hippocratea grandiflora (an un- 
known plant, which I have referred to the following species); he cites as the specimens 
seen by him Wilson's plant from Jamaica, Wright's from Cuba, Guilding's from 8. Vin- 
cente, all belonging to the genus Pristimera. From this it will be seen what little 
reliance can be placed in the determinations given in Dr. Grisebach's work. 
Meyer also confounded another Guiana plant with Rudge's species, under the name of 
Tontelea malpighiefolia; it is from Surinam, and described by me in a subsequent 
page under Tontelea longifolia. 
This species differs from the preceding in its stouter, more ascending branches, with 
more approximated axils, in its larger, more elongated, and more erect leaves, in its 
more compact inflorescence, with less-spreading ramifications, in its larger flowers, its 
more cuneiform, almost nerveless capsules. The leaves are 21-34 in. long, 13-12 in. 
broad, on a petiole 31-4 lines long; the peduncle is 7 lines long, its primary branchlets 
3 lines, the others diminishing upwards; the flower expanded is 5 lines in diameter; 
the capsules (of which one remains, and evidently in quite an immature state) are 21 in. 
long, 12 in. broad, and are not yet swollen by the growth of the seeds.
