5. PRIONOSTEMMA SETULIFERA, nob.: ramulis suboppositis, longis, patentissime divari- 
catis, teretibus, rufule setulosis, junioribus subangulatis, hispidule subferrugineis : 
foliis ovalibus, utrinque subrotundatis, margine cartilagineo crenulato-subserratis, 
supra pallide viridibus aut fuscioribus nervis tenuissimis, valde divaricatis et 
arcuatim nexis, reticulatis, opacis, obsolete hispidulis, taetu asperulis, subtus palli- 
dioribus, nervis venisque transversis prominulis et e granulis minutis densius setu- 
ligeris; petiolo tenui, tereti, supra sulcato, hispidulo, limbo 10-plo breviore: 
paniculis axillaribus, petiolo 4-plo longioribus, hispidulis, pedunculatis, breviter 
2-3-chotome ramosis, ramis brevibus crebriter divisis, ultimis flores 3 pedicellatos 
inter bracteolas gerentibus, pedicellisque hispidulis; sepalis parvis, fuscis, rugulose 
carnosulis, rigide pilosulis, margine albidulo pectinato-fimbriatis; petalis 3-plo 
longioribus, rotundato-ovatis, breviter unguiculatis, fusce carnosulis, extus obsolete 
puberulis, marginibus tenuibus minute dentieulatis; disco depresso, in medio 
pulvinato, carnoso, fusco, scabridule ruguloso, margine basali late explanato, sub- 
pentagono; filamentis latis, crassiusculis, rugulosis ; ovario conice trigono, profunde 
3-suleato; stylo brevi; stigmate albido, brevissime trilobo. In Guatemala: v. s. in 
herb. Hook., Fredericsthal. 
- A very distinct species, with extremely divaricating branchlets not quite opposite, and 
with axils about 2 in. apart: the leaves are 21-3 in. long, 12-2 in. broad, on a petiole 
21—3 long: in the younger branchlets they are only 15 lines long and 10 lines broad ; 
the peduncle of the inflorescence is 4-6 lines long, its branchlets 1-2 lines long; the 
pedicels are 1j line long, rather stout, and hispidulous: all the flowers are in bud, 
the petals being 13 line long, 1 line broad; the bracteoles are very acute, hispidulous, 
with ciliated margins. 
6. PRIONOSTEMMA KUNTHIANA, nob.: Anthodon decussatum, H., B., K. (non R. & P.), 
Nov. Gen. v. 140, tab. 443: scandens, ramulis teretiusculis, glabris: foliis oppositis. 
elliptico-oblongis, imo subacutis, apice subacuminatis, remote crenato-serratis, 
coriaceis, glabris, supra nitidis, costa nervis arcuatis venisque reticulatis prominulis, 
subtus vix pallidioribus; petiolo canaliculato, glabro, limbo 10-12-plo breviore : 
paniculis axillaribus et terminalibus, folio dimidio brevioribus, dichotome ramosis, 
cum ramo brevi abortivo in dichotomiis, glabris; bracteolis parvis, acute ovatis, 
glabris; floribus majusculis, pedicellatis; sepalis parvis, rotundatis, glabris; petalis 
multoties majoribus, ovato-oblongis, obtusiusculis, planis, crassiusculis, flavo-cineras- 
centibus, marginibus argute dentatis, breviter unguiculatis, sub disco in sertis, 
expansis; disco carnoso, depresse pulvinato, margine late expanso, subtrigono ; 
ovario 3-lobatim sulcato, 3-loculare, loculis 8-ovulatis; stylo brevissimo ; stigmate 
obsolete 3-lobo. In Venezuela, circa Angostura (Bonpland): non vidi. 
From the above ample description of Kunth, this plant appears to belong to this 
genus (not to Anthodon), as it corresponds in its most essential characters. It has 
greatly the habit of P. scabridula, agreeing in the size and shape of its coriaceous leaves, 
with very prominent stout nervures, also in its trichotomous inflorescence with large 
fleshy flowers. Its leaves-are 43 in. long, 18-19 lines broad, on a petiole 4-5 lines long;
