This is a species of much taller growth, its long slender branches being scandent, but 
in general appearance like those of the two preceding species. The axils of its branches 
are 11-1j in. apart; the leaves are 23—5 in. long, 11-21 in. broad, on a petiole 3-4 lines 
long. The panicles are 11-143 in. long, with alternate branches 3-4 lines apart, and uni- 
braeteolated at base, all again and again divided; the flower expanded is 21 lines in 
diameter, and when living is sulphur-coloured. | 
4. PERITASSA COMPTA, nob.: scandens, ramulis ruguloso-striatis, cinereis, verruculis con- 
cavis crebre asperatis, junioribus subcompressis : foliis cuneato-oblongis vel cuneato- 
ovatis, apice rotundatis, planis, coriaceis, integerrimis, marginibus cartilagineis, supra 
fusco-viridibus, subopacis, sub lente granulis minutissimis scabridulis brevissime 
-setiferis glauco-pruinosis, nervis valde divaricatis longe intra marginem arcuatim 
nexis omnino immersis, eveniis, subtus pallidioribus, brunneo-opacis, remotiuscule 
granulosis, sub lente creberrime et minutissime punctulatis, nervis paulo prominulis ; 
petiolo fusco, profunde canaliculato, subrugoso, limbo 12-plo breviore: paniculis 2-3 
subfasciculatis e gemma bracteolata axillari ortis, folio 4-plo brevioribus, alternatim 
ramosis, ramis tenuibus ramulisque alternis iterum divisis, subangulatis, interdum 
pilis rigidis brevissimis scabridulis; bracteolis parvis, acutis, denticulatis, alternatis ; 
floribus parvis, in ultimis ramulis approximatis, hine subaggregatis, glaberrimis ; 
sepalis rotundatis, fuscis, crassis, rugulosis, margine membranaceo sinuato-denti- 
culatis; petalis duplo longioribus, in alabastro rotundatis, fuscis, crassis, margine 
membranaceo eroso-pectinatis; disco breviter tubuloso, albido, valde membranaceo, 
margine erosulo; antheris parvis, flavis, lobis 2 ovatis, parallelis, ad connectivum 
latum nigrum apice excurrens extrorsum adnatis. In Guiana: v.s. in herb. Mus. 
Brit., Guiana Brit. (Schomburgk) ; in herb. Hook., Essequibo (Schomburgk, 38). 
The plant is described as a “ ligneous climber.” In habit and floral structure it re- 
sembles the preceding, and agrees with all the others in the peculiar surface of its leaves. 
The axils of its branches are about 1 inch apart; the leaves are 33-52 in. long, 13-2 in. 
broad, on a petiole 4-5 lines long; the panicles are 1-14 in. long, upon peduncles 6 lines 
long; the flowers are all in bud, 2 line in diameter. 
5. PERITASSA RUBICUNDA, nob.: arbuscula, ramulis vix scandentibus, fuscis aut rufes- 
centibus, subangulatis, rugoso-striatis, tuberculis nigris concavis crebre verruculosis, 
axillis dilatatis: foliis oblongo-ovatis, imo obtusis et petiolum versus brevissime 
euneatim decurrentibus, apice obtusis, vel in acumen breve obtusulum crassum re- 
pente constrictis, sepius naviculari-plicatis, coriaceis, integerrimis cum margine car- 
tilagineo, supra viridibus et paulo rubescentibus, opacis, rugulosis et creberrime sub- 
scabridulo-punctulatis, subtus pallidioribus, subferrugineo-opacis, costa nervisque 
tenuissimis fere immersis, subeveniis, sub lente creberrime granulatim rugulosis ; 
petiolo valido, fusco, canaliculato, angulato-striato, ruguloso, limbo 12-plo breviore: 
panieulis 2-3 subfasciculatis e gemma axillari bracteolata ortis, glabris, alternatim 
ramosis, rubescentibus, ramis repetitim divisis ramulisque angulatim striatis sæpe 
verruculosis; bracteolis parvis, acutis, alternis, rufo-ciliatis; floribus parvis, pedicel-
