Dr. Diels attached the name Rh. cephalanthum, Franch. var. 
platyphylium, Franch. to Forrest’s specimen No. 4155, and under 
the name the plant is recorded in Plantae Forrestianae.* There 
has been no other publication of the name, to my knowledge. 
From Dr. Diels it has been learned that he found the name 
written by Franchet on a sheet in the Paris Herbarium and 
adopted it, as he did in several other like instances. From the 
facts one may conclude that Franchet intended to mark the 
plant as different from Rh. cephalanthum, Franch., but circum- 
stances did not permit of his making critical examination of it,
