terised by the flowers not closely sessile in a globular head, 
but pedicellate, so as to form a simple umbell. 
23. C.? obovata, (sp. n.,) ramulis rufo-puberulis, stipulis 
parvis subulatis, pinnis 2-3-jugis, foliolis 2-4-jugis obovato- 
orbiculatis v. oblique subrhombeis uninerviis junioribus 
ciliatis demum glabris nitidis, pedunculis petiolo communi 
sublongioribus, floribus breviter pedicellatis, calyce turbinato 
dentato corolla subinfundibuliformi dimidio breviore.—Fo- 
liola rigidula, ultima 1-2 poll longa.  Petioli sepius eglan- 
dulosi, interdum vero glandulam observavi parvam inter 
pinnas juge infimae. ^ Pedunculi 2-3-pollicares. Capitula 
magna, speciosa. Pedicelli fere 2 lin. longi, corolla 2 lin. v. 
paullo longior, membranacea, minute puberula. Legumen 
non vidi.— Brazil, Lob. 
24. C. tubulosa, (sp. n.,) ramulis lutescenti-v. ferrugineo- 
pubescentibus, stipulis lanceolato-linearibus, pinnis 2-4-jugis, 
glandula scutelleformi ad basin petioli, jugalibusque sepe 
parvis inter foliola, foliolis 1-3-jugis oblique obovato-orbicu- 
laribus subrhombeisve supra parce subtus densius pubescen- 
tibus, pedunculis petiolo communi subbrevioribus, floribus 
breviter pedicellatis, calyce tubuloso ferrugineo-tomentoso 
breviter dentato corolla semi-5-fida sericeo villosa dimidio 
breviore.—Ramuli crassi sulcati. Stipule circa 3 lin. longe, 
rigidule, sepius obtuse.  Petioli communes semipedales ; 
Foliola iis C. obovate similes. Glandula petiolaris maxima, 
jugalia pauca minima. Capitula circa 10-flora. Pedicelli 
2 Jin., calyces 3 lin. longi, molliter tomentosi. Stamina bipol- 
licaria.— Brazil: banks of the Rio San Francisco, near

25. C. leptopoda, (sp.n.,) glabra v. molliter pilosa, stipulis 
maximis foliaceis late cordatis multinerviis reticulatis, pinnis 
unijugis, foliolis 2-4-jugis oblique obovato-falcatis, pedunculis 
gracilibus petiolo longioribus, pedicellis filiformibus flore 
multoties longioribus. — Frutex tripedalis, nunc glaber- 
rimus glaucescens, nunc totus pilis mollibus patentibus 
vestitus. Stipule superiores fere pollicem longe et late,
