ON SOTTTH-AMERICAN APOCTNACEiE. 137 



trorsum tortis et convolutis ; staminibus ad contractionem tubi jusertis. In Rio de Janeiro^ v. v. 

 in montibus OrganensibuSj in herb, meo (4056) . 



I found this species in flower in January 1838. The fistulose scandent branches are 

 ■J in. thick, with axils 7 in. apart; the opposite leaves are 3^-6 in. long, 2i-3| in. broad, 

 on petioles l|-2 in. long, which are inserted |-1 in. above the base of the blade ; panicle 

 spreading, 8-4 in. long, subtomentous ; peduncle bare at the base, 2 in. long; its 3 

 branches | in. long, each bearing 5-6 approximate flowers, on pedicels bracteate at 

 their base, bibracteate in the middle, 8 lines long ; bracts 6 lines long, 1 line broad ; 

 sepals the size of the bracts, reticulately veined, each having within at the base a small 

 alternate scale ; tube of corolla 1 in. long ; segments 9 lines long, 4 lines broad ; anthers 

 slender, 4J lines long, acutely acuminate, and sharply biaristate at the base, subpuberu- 

 lous behind ; disk 6 free fleshy roundish lobes nearly as long as the 2 roundish glabrous 

 ovaries; style slender; clavuncle incrassate, glandular, supported upon a peltate 

 membranaceous appendage. 



8. Stipecoma ovatAj nob. : scandens^ ramis strictis, crassis, teretibus, striatis, fistulosis, pallidis, cinereo- 



pruinosis, sparse lenticellatis ; axillis remotis, linea transversali notatis : foliis ovatis, imo orbicu- 

 laribus et nndulato-plicatis, apice sensim late acutis et mucronatis, marginibus revolutis, crassiuseule 

 chaxtaceis, supra fusco-viridibus, opacis, corrugulatis^ costa nervisque immersis, subtus flavide 

 ferrugineis; opacis, corrugulatis et granulosis, obsolete tomentosis, nervis basalibus 7 radiantibus, 

 lateralibusque utrinque 7 prominulis^ versus marginem arcuatim nexis ; petiolo vix cra;sso, angulato, 

 corrugulato, imo cirrose reflexo : pedunculo fructifero crasso, petiolum sequante ; folliculis 2 sub- 

 pedalibuSj paullo arcuatis, teretibus, striatellis, cinereo-nigrescentibus, apicibus subangustatis arete 

 JTlgatis: cseteris ut in char, generico. In Brasilia: v. v. infructu, montibus Organeijsibus, in herb, 

 meo (4058) ; v. s. in herb. Mus. Brit. Itagoahy (Bowie and Cunningham) . 



The branches are 3 lines in thickness, very fistulose, rigid, with axils 8 in. apart ; the 

 leaves are 4^-5^ in. long, 3-4 in. broad, on petioles l^-lj in. long, inserted | in. within 

 the border. The fructiferous peduncle, with the cicatrices of 2 abortive flowers, is 1^ in. 

 long; the follicles are 10^ in. long; the seeds (including the long glabrous rostrum 

 6 lines) are 14 lines long, 1 line broad, with an apical s.preading coma 13 lines long ; 

 funicle beneath the ring of the coma very short, but distinct. 



The follicles in Bowie and Cunningham's specimen, not yet ripe, are 7^ in. long, 

 4 lines broad. 



A drawing of this species in fruit, showing the carpical structure, and the analysis of 

 its seeds are given in Plate XIX. 



9. Stipecoma parabolicAj nob. : scandens, foliis subpeltatis, oblongis, imo rotundatis, supra medium 



sensim angustioribus, apice in acumen sublineare acutum recurvulum attenuatis, marginibus integris 

 subrevolutis, crassiuseule chartaceis, supra profunde viridibus, glabriusculis, nervis immersis, ad 

 insertionem petioli glandula rotundata signatis^ subtus opacis, ferrugineo-pruinosis ; petiolo tenui, 

 recurvato, 6plo breviore quam limbo, paullo intra marginem subtus peltatim affixo : cseteris ignotis. 

 In Brasilia : v. s. in herb. Mus. Brit, prope San Paulo (Bowie and Cunningham), sineflore etfructu. 



The leaves are 4J in. long, 2 in, broad, on a somewhat slender petiole f in. long, in- 

 serted 1 line within the margin.
