358 MR. J. MIERS ON THE HIPPOCRATEACEA OF SOUTH AMERICA. 
pentagono, retrorsum brevissime scabrido-pilosulo; cæteris preecedentium: cap 
sulis 3, distinctis, ovatis, rotundatis, breviter stipitatis. In Antillis, ins. Trinidad 
(Van Rohr): v. s. in hb. Mus. Brit., Trinidad (Van Rohr); in herb. Hook., Trinidad 
(Lockhart ; Purdie, 13). 
The synonyms given above are confirmed by copious evidence. Vahl confounded this 
species with Aublet's Tontelea scandens, with which it has not the slightest affinity, 
others following his example, but giving it other names. M. Payen examined two other 
specimens of this or a kindred species of which he gives no details, one from Trinidad, 
collected by Anderson, the other from S. Vincente, collected by Callays ; it is uncertain 
to which of these may be assigned the analytical details he has published, both specimens 
existing in the herbarium of Delessert, under the manuscript name of Hippocratea 
grandiflora: these analytical details of the floral and carpical structures agree in the 
main with the characters of this genus; but the pulvinated portion of the disk is con- 
founded with the base of the filaments in fig. 35, probably through the fault of the 
engraver. The capsules shown in figs. 42 & 43 are in an immature state, and of a 
diminished size, as the seed in fig. 44 plainly denotes: this agrees with that I have 
described in the typical species, only that the basal wing is still shorter. The capsules 
described by Dr. Grisebach do not belong to this species; they conform in size and 
shape to those of Hippocratea Plumieri, nob. In this species the opposite axils are 
2-23 in. apart; the leaves are 3-6 in. long, 13-3 in. broad, on a petiole 3 lines long: 
as the leaves in the young flowering branchlets are very deciduous, the inflorescence, 
consisting of 3 or 4 separate panicles, thus assumes a more compound appearance; but 
the peduncle of each distinet panicle is 4-6 lines long, its branches 2 lines, the pedicels 
being 2-3 lines long; the flower expanded is 6 lines, and the disk 3 lines in diameter. 
4. PRIONOSTOMA VELUTINA, nob.: Salacia velutina, Camb. Fl. Bras. Mer. ii. 108 : frutex 
humilis, caulibus a basi plurimis; ramulis teretibus, glabris, griseis: foliis oblongo- 
lanceolatis, imo gradatim angustatis, apice acutiusculis vel rarius rotundatis, 
integerrimis, marginibus revolutis, coriaceis, supra pube brevissima velutinis, subtus 
pallidioribus, glabris, nervis utrinque prominulis; petiolo crassiusculo, supra sulcato, 
subtus convexo, limbo 16-plo breviore: paniculis axillaribus, subsessilibus, folio bis 
triente brevioribus, ramosis, ramulis subpuberulis ; bracteolis subulatis, ciliolatis ; 
floribus brevissime pedicellatis; sepalis rotundis, puberulis, ciliolatis; petalis 2-plo 
longioribus, oblongis, obtusis, patentibus, marginibus eroso-denticulatis, viridulis ; 
disco erenato-cyathiformi, margine basali expanso ; stylo brevissimo, trigono ; ovarii 
loculis 2-ovulatis. In Brasilia, prov. Minas Geraes, San Bento (St.-Hilaire): 
non vidi. 
This is described as a small shrub 2 or 3 feet high, and seems to approach all the 
preceding species in its entire downy leaves, its puberulous greenish flowers, with 
dentieulate sepals and petals, and an expanded disk. Its leaves are 3—4 in. long, 10-13 
lines broad, on a petiole 2-3 lines long : the panicle is 1-12 in. long, apparently branching 
a little above its base; the sepals are 2 line in diameter; the petals 13 line long.
