356 MR. J. MIERS ON THE HIPPOCRATEACEJE OF SOUTH AMERICA. 
medium sensim angustioribus, imo rotundatis, apice rotunde truncatis, subemargi- 
natis, per medium marginesque carinatis, valde coriaceis, pallidis, parallele nervosis, 
tactu asperulis, singulis 8-spermis. In Guiana; Cayenne (Richard): v. s. in herb. 
variis, Guiana Brit. (Schomb. 710-270, in flore et fructu) ; Guiana (Martin, in flore). 
This species was considered by Vahl and DeCandolle identical with Tontelia scandens, 
Aubl., which was described by the former as T'onsella scabra, by the latter as Salacia 
scabra; but it is very different from either of these genera: it is well represented in 
Schomburg’s specimens. Its leaves are 13-22 in. long, 11-19 lines broad, on a petiole 
2-3 lines long. The panicle is 2-23 in. long, expanding to a breadth of 12-2 in.; the 
pedunele is 15 lines long, its branches 3 lines long; the flower, expanded, is 4 lines in 
diameter; the petals, 2 lines long, are inserted by their claws beneath the broad margin 
of the disk, which is + line in diameter and as high. The capsules are 2; in. long, 
12 lines broad, each opening by a median suture into two compressed navicular valves; 
each bears eight seeds, all attached to the rounded receptacle common to the six valves, 
which is about the size of a flattened pea, and upon which are seen the twenty-four very 
short, persistent funicles from which the seeds have fallen: the seed is nearly 2 in. long, 
3 in. broad, including the nuciform apex, 9 lines long, 4 lines broad, and 6 lines thick ; 
the embryo which fills this space is 5 lines long, 23 lines broad.

Griseb.), Pl. Guian. i. 10, tab. 8 (cum foliis male depictis); DC. Prodr. i. 568: 
ramulis adscendentibus, teretibus, substriolatis, infuscatis, tuberculato-rugulosis : 
foliis seepius imperfecte oppositis, subassurgentibus, oblongis, imo obtusis aut rotun- 
dioribus, apice in acumen breve obtusum subito constrictis, rigide coriaceis, integris, 
margine cartilagineo revoluto, supra pallidis, subnitentibus, costa nervisque utrinque 
6-7 rubidulis immersis, subtus pallidioribus, opacis, costa nigra nervis arcuatis 
venisque reticulatis valde prominentibus, glabris, sub lente minutissime punctulato- 
rugulosis, tactu asperulis; petiolo subtereti, canalieulato, fusco, ruguloso-striato, 
limbo 10-12-plo breviore; stipulis minimis, acutis, caducis: paniculis subcorymbosis, 
axillaribus et terminalibns, folio paulo brevioribus, pedunculatis, valde ramosis, 
ramis alternatim assurgentibus, subremotis, subumbellatim divisis, ramulis 8—4 sub- 
fasciculatis, iterum divisis, cum floribus 1-2 pedicellatis in axillulis, bracteolatis, 
rigide fulvo-tomentellis ; floribus in ramulis ultimis subcongestis; petalis orbiculatis, 
unguiculatis, ad medium pilosulis, marginibus glabris, membranaceis, profunde pec- 
tinatim incisis ; disco, staminibus pistilloque preecedentis : capsulis 3, distinctis, e basi 
cuneatim oblongis, apice subemarginatis, immaturis valde compressis, in medio vix 
carinatis, haud nervosis, coriaceis, fuscioribus, tactu asperulis. In Guiana: v. s. 
specimen typicum in herb. Mus. Brit., Cayenne (Martin) ; in herb. Hook., Guiana 
(Talbot). 
Rudge's drawing, an exact tracing of one of the typical specimens above cited, is 
correct in all respects except in the leaves, which are too lanceolate, narrower, and not 
abraptly apiculated, being evidently copied by mistake from another specimen, which I
