Cult. Corrida is a genus of very shewy flowering shrubs. 

 They will thrive well in an equal mixture of loam and peat, and 

 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.

 like those of Corrafa. Shrubs, with alternate oval leaves, full 

 of glandular pellucid dots, and are, as well as the branches, 

 peduncles, and leaflets of involucre, closely covered with starry 

 down. The many-flowered involucre appears like one terminal 

 pedicellate flower.
