Sect. I. Receptaculum paleis nullis. Pericarpium papposum. Flores flosculosi. 
Calyx 4-13-phyllus, parum infundibuliformis aut cylindraceus, bracteis aliquot juxta basin spar- 
ericarpia sessilia vel pedicellata, Pappus exquisite dentatus. Receptaculum marginibus 
scrobiculorum nunc obtusis equatum nunc membrana dentat& coronatis scabrum. Herba, vel 
Frutices succulenti. Folia planiuscula, dentata, facie seepe Sonchorum et Tussilaginum ; vel succus 
lenta, simplicia, pinnatifida, bipinnatave. Flores albi, lutei, aurantiacive: paniculis 5-150-floris ; 
nalibus. Genus } ‘um specierum in vivis tantummodo stabiliendum: non nullas 
bracteis carentes juste sepuravit Cl. Schreber, sed utinam alio titulo; cum species succulenta Africa- 
ne, que receptaculo scabro ab herbaceis Europeis longe abludunt, antiquum Kleiniew nomen potius sibi 
# Herbacee. 
C, foliis laciniato-dentatis, succulentulis, inferioribus lanceolatis, superioribus plus minus sagitta-

Botanists are obliged to Dr. Roxburgh, who has introduced so many Hindostan plants into 
Great Britain, for the knowledge of this Cacalia; and I learn from his useful Manuscripts, that it 
a foot and a half to five feet and a half long, divided near the base into several spreading branches, 
a little angulated and generally smooth. Leaves in shape like those of Sonchus, of a dark purple 
Receptacle rough with a narrow toothed membrane which surrounds the scars of the seeds : 
this respect it differs very materially from the Alpine Cacali: s of Switzerland, and | — As 
if it can remain in the same genus with the African shrubby speci It was communicated by 
the Right Hon>!e, Charles Greville. — 7 2
