MR. J. MIERS ON THE HIPPOCRATEACE/E OF SOUTH AMERICA. 337 
4.. HIPPOCRATEA VAHLIANA, nob.: Hippocratea obcordata, Vahl. (non Lam.) Enum. 
ii. 22: Hippocratea scandens, Griseb. (non Jacq.), Pl. Cub. p. 56: ramulis op- 
posite patentibus, curvatis, teretibus, axillis transversim nexis, glabris, junioribus 
sub-4-gonis, fulvo-tomentosis : foliis ellipticis, acutis, vel elliptico-oblongis, imo rare 
subobtusis, sæpius acutis, superne sensim acuminatis, margine serrulatis, dentibus 
obtusis vel mucronatis, subrevolutis, limbo firme rigidulo, supra viridibus, subopacis, 
sub lente minute granulosis, nervis tenuibus, valde reticulatis, subtus concoloribus 
aut brunnescentibus, nervis prominulis; petiolo tenui, canaliculato, limbo 15-plo 
breviore; stipulis acutis, subsetaceis: paniculis corymbosis, axillaribus et termina- 
libus, 2-3-chotome divisis, folio dimidio brevioribus, ferrugineo-tomentosis, pilis 
articulatis, ramis valde divarieatis cum ramulis 1—3 brevioribus in dichotomiis; floribus 
pedicellatis, pedicellis sepalis petalisque extus rigide rufo-tomentellis, his intus 
subglabris et apice barbatis; filamentis latiusculis, ciliolatis; disco late conico, imo 
paululo latiore, tomentello ; ovario fere abscondito; stylo tenui, exserto; capsulis 3, 
distinetis, anguste oblongis, imo angustioribus, apice rotundatis, compressissimis, in 
medio carinatis, leviter striolatis, valvis tenuiter testaceis; seminibus samaroideis, 
locello oblongo, obliquo, ala crassiuscule membranacea paulo breviore sustento. In 
Antillis et in Guiana: v.s. in herb. Mus. Brit., Cayenne (spec. typ. Van Rohr, in 
^1 flore et fructu); in hb. Hook. Cuba, ad Monte Verde (Wright, 1147) ; Cayenne ( Poi- 
team, in fructu immaturo). 
Van Rohr's plant accords tolerably well with Vahl’s description, established upon 
another specimen of the same collector: he erred, however, in considering it identical with 
the H. obcordata, Lam., and with H. scandens, Jacq. Vahl was also wrong in stating 
that the leaves are rounded at their base, an oversight to make it conform with Jacquin’s 
drawing. In this species the axils are 1-1} in. apart; the leaves are 3-57 in. long, 1i- 
li in. broad, on a petiole 21-3 lines long: the axillary panicles are nearly 2 in. long, 
the terminal ones rather longer. The capsules are 18 lines long, 7 lines broad; the seeds 
are 14 lines long, 4 lines broad, have a superior, roundish oblong, rather oblique, fuscous, 
coriaceous, compressed cellule, 8 lines long, supported on a somewhat lateral wing, which 
is thicker and more opaque than usual.
