ON THE GENUS SYMBOLANTHUS. 
By Jons Miers, Esa., F.R.S., F.LS., ETC. 
(Prare XCIV.) 
The genus Symbolanthus, established by G. Don in 1837, consisting 
of two species, natives of New Granada and Peru, was divided by 
Grisebach, in 1845, into two separate genera: to the former species, 
originally described by Kunth as Lisianthus anomalus, he now gave 
the name of Leiothamnus anomalus, designating the latter species, 
first described in the ‘ Flora Peruviana’ as Lisianthus calycogonus, R. 
and P., under the name of Syméolanthus calycogonus, Griseb. ; but 
Don's name of S. Pavonii will claim the preference on account of its 
having a priority of eight years. Among the plants collected by Weir 
in 1863, for the Royal Horticultural Society, is a new and handsome 
species of this genus from the Rio Magdalena, which is here figured. 
A more detailed character of the Peruvian species is here first given, 
in order that Weir's plant may be compared with it.
