90 MONOGRAPH OF 



as stated, but commonly double, the outward 

 of 2 sepals, being mistaken for bracts, altho' 

 they persist in the fruit, and are quite similar to 

 the extra sepals of the CISTIDIAN tribe to which 

 this Genus evidently belongs, notwithstanding 

 the reduced stamens and seeds. This Genus 

 is in fact so ner to Anthelis (Helianthemum 

 T.) that the main distinction consists only in 3 

 petals instead of 5, and it is supposed that the 

 original L. major of Lin. was also his Cistus 

 canadensis ! or 9. variety of it !
