Cult. Correa is a genus of very shewy flowering shrubs. 
They will thrive well in an equal mixture of loam and peat, an 
ripened cuttings will strike root freely if planted thinly in a pot 
of sand, and a bell-glass placed over them, without heat. They 
are also increased by inarching the rarer on the commoner sorts.

one, imbricate, containing many flowers. Flowers sessile, ed

of glandular pellucid dots, and are, as well as the branc es 
peduncles, and leaflets of involucre, closely covered with sany 
down. The many-flowered involucre appears like one term
