 spread of which is greater than that of the leaves- calyx 

 large, deeply divided into five foliaceous lobes; corolla' white 

 with an occasional tinge of rose, 3*in. to 4iin. long, and as broad 

 at the mouth, campanulate, much like that of Lilium candidum ; 

 lobes very broad, waved, spreading; stamens ten; peduncles

B. D. hybridum (hybrid). A hybrid between R. Dalhousice and 

 R. formosum. The flowers are as large as those of the former,

 are intermediate in size, and quite glabrous. (B. M. 5322.)
