338 MR. J. MIERS ON THE HIPPOCRATEACEZ OF SOUTH AMERICA. 
barbatis; disco alte subconico, longitudinaliter sulcato, tomentello. In Guiana, 
Cayenne (Richard) : v. s. in herb. Mus. Brit., Cayenne, in sylvis circa pedem Gabiullæ 
(Martin). 
The above specimen accords well with Vahl's description: the axils are 14 in. apart; 
the leaves are 21—31 in. long, 1-1} in. broad, on a E 3 lines long: the peduncle is 
lin. long; the primary divaricating branches are + in. long, compressed, the pedicels 
1 line long; the flower in bud À line in diameter, when expanded 2 lines in breadth, all 
parts conforming with the santas characters of the genus. 
6. HIPPOCRATEA AUBLETIANA, nob.: Hippocratea volubilis, Aubl. (non Linn.), Pl. 
Guian. i. 30: scandens, ramulis teretibus, angulato-striatis, patentim divaricatis, 
junioribus cinereo vel fulvescente puberulis, corrugulato-striatis: foliis ovatis, imo 
rotundatis et in petiolum subito breviter cuneatim attenuatis, apice rotundiusculis 
et in acumen brevissimum obtusulum repente constrictis, crenato-serratis, supra 
pallide viridibus, ssepe fuscioribus, subnitentibus, aut opacioribus, nervis tenuibus 
arcuatim nexis venisque reticulatis vix prominulis, subtus rubescenti-brunneis, 
opacis, sub lente minute granulatis, nervis prominulis: petiolo tereti, canaliculato, 
filis spiralibus repleto, limbo 10-plo breviore: paniculis axillaribus, pedunculatis, 
supremis seepe dilapsu foliorum in corymbum terminalem laxe expansum confectis, 
ferrugineo-tomentellis, diehotome ramosis, ramis patentim divaricatis iterumque 
divisis, cum ramulis 2 brevibus in dichotomiis; floribus rufo-tomentellis; petalis 
intus barbatis ; disco alte conico, tomentello, apice tomentoso ; filamentis latis, extus 
tomentellis, subreflexis; ovario 3-gono, semiocculto, loculis 6-ovulatis: capsulis 3, 
distinctis, anguste oblongis, imo cuneatis, apice emarginatis, compressissimis. In 
Guiana: v.s. in herb. Mus. Brit., Cayenne (Aublet, in flore); Guiana Brit. (Schomb. 
410, in flore); Peru (Pavon, in flore et fructu) ; in hb. Hook., Peru, ad Coroico, in 
sylvis, alt. 3000—4000 ped. (Pearce, in fructu). 
This species is well distinguished from others by its broadly ovate subcoriaceous leaves 
with erenated margins, which (in the Peruvian specimen) are sometimes more gradually 
attenuated toward the petiole: they are 21—3$ in. long, 13-2 in. broad, on a petiole 3-5 
lines long: the axillary panicle, including the peduncle (10-16 lines), is 14-24 in. long, 
the very divaricated primary branches are 6-9 lines long, the rest gradually decreasing, 
the last very short: the flowers are said to be **cream-coloured," the petals are 2 lines 
long, the disk 13 line high and broad; in the Peruvian plant the immature capsules are 
18 lines long, 6 lines broad: in Pearce's specimen the capsules, not so young, are 2 in. 
long, 10 lines broad. The whole plant, especially the inflorescence, is replete with spiral 
vessels.
