brunnea striata vix prominulis; petiolo ruguloso, torto, fusco, canaliculato, limbo 
9-plo breviore: floribus 3—4, longiuscule pedicellatis, in axillis fasciculatis, e gem- 
ma enatis, mole mediocri; pedicellis subeapillaribus, glabris; petalis 4-plo longi- 
oribus; sepalis parvis, semiorbicularibus, margine pectinato-ciliatis ; -petalis 4-plo 
longioribus, late cuneato-ovatis, rotatis, integris, submembranaceis; disco carnoso, 
conice pulvinato, imo late expanso; filamentis dilatatis, disco duplo longioribus, 
subreflexis; antheris parvis, subglobosis; ovario conico, profunde trianguloso ; 
stylo brevi; stigmate obtusatim 3-denticulato. In Guiana Britannica: v.s. in herb. 
Hook. (Schomb. 347). 
This is a well-marked species, apparently scandent, with slender patent branches, the 
axils being i—$ in. apart; the opposite leaves are 3-43 in. long, 13-2 in. broad, on a 
petiole 4-6 lines long; the almost capillary pedicels are 43 lines long; ; the flower ex- 
panded is 33 lines in diameter.

DC. Prodr. i. 569: Tonsella oblongifolia, Spr. Syst. i. 178: ramis validis, teretibus,

gentibus, teretibus, ad nodos oppositos dilatato-compressis, opacis, flavidiusculis, 
ruguloso-striatis: foliis elliptico-oblongis aut oblongo-ovatis, imo rotundatis, apice 
€ aut in acumen brevissimum obtusulum canaliculatum recurvum terminatis, 
is, coriaceis, marginibus crasso-cartilagineis subrevolutis, integris, supra palli- 
Abina, opacis, sub lente impresso-punctulatis, ad nervos tenues parallele divergentes 
venasque reticulatas omnino immersas sulcatulis, costa vix prominula, subtus flavide 
pallidioribus, valde opacis, costa prominula, nervis tenuibus, impresso-punctatis ; 
petiolo erassiusculo, semitereti, subcanaliculato, undique rugulose corrugato, limbo : 
12-14-plo breviore : pedunculo axillari, gemmzeformi, bracteolato-squamoso, pedicellis 
4-12 fasciculatis munito; pedicellis petiolo vix longioribus, subtenuibus, striolatis, 
glaucis, l-floris; floribus majusculis, rotatis; sepalis subrotundis, medio crassius- 
culis, margine late membranaceis, ciliato-fimbriatis; petalis duplo longioribus, sub- 
membranaceis, obovatis, ciliato-denticulatis : cseteris preecedentium. In Brasilia, ad 
Rio San Francisco (Martius): v. s. in herb. variis, prov. Piauhy, ad Gurguéa (Gard- 
ner, 2494). 
I have referred Gardner's plant to this species of Von Martius from the San Francisco 
river, as the Serra de Gurguéa is within the range of that river bounding the province 
of Piauhy, and as the above plant answers to Martius's description. Gardner states that 
it is a tree 20 feet high, growing on the banks of the river Gurguéa (which he mispells 
Gurgéa). The axils of the branches are 4-11 in. apart; the leaves 3343 in. long, 
13-2 in. broad, on a petiole 3-34 lines long; the axillary bud-like peduncle is thick, 
sessile; the pedicels are 3-5 lines long; the flower expanded i is 4 lines in diameter.
