sight of some of Dumortier's originals, but in vain. Having 

 convinced myself of the distinctness of C. muWfora (nob.) from 

 C. connivens, I sought for some notice of the former in the works 

 of previous authors, and it seemed to me possibly identical with 

 C. lunidafolia Dum. The name suited well enough — not so well 

 the meagre diagnosis. The first question I asked M. Delogne 

 was about this plant, and he has been good enough to send for 

 my inspection two specimens from the herbarium, the one marked 

 by Dumortier (in the earlier part of his career) Jg. limulata Dum., 

 the other Ceph. hmidafoUa Dum. The latter from the classic 

 exsiccata of Moug. and Nestler is conclusive. I am glad of this, 

 as it gets rid of two names, mulfiflora and media, which were likely 

 to lead to a fight."
