In our Revision of 1888 (p. 102), under #. prostratum we discussed the standing of 
“americanum, relerred to Walter by Sprengel, and of /. integrifolium Walter. As 
then stated, there is no /. americanum Walter, Sprengel having copied under that 
name the description of 1. integrifolium Walter. It has now been discovered by Mr. 
James Britten and Mr. Ek. G. Baker, of the British Museum, who have examined the 
type of FE. integrifolium Walter, that it is identical with L. virgatum Lam.
