Cooperia
(named after Mr. Joseph Cooper, a very successful cultivator, and at one time gardener at Wentworth House, in Yorkshire, the residence of Earl Fitzwilliam). ORD. Amaryllideae. Closely allied to Zephyranthes. There are two species of this genus in cultivation, with solitary Primrose-scented flowers, which are remarkable in the order, on account of their expanding during the night. They are hardy only in sheltered situations. For culture, propagation, &c., see Zephyranthes.
