ON THE GENUS SYMBOLANTHUS.
By John Mieks, Esq., F.R.S., F.L.S., etc.
(Plate XCIV.)
The genus Symbolmiihus, established by G. Don in 1837, consisting
of two species, natives of New Granada and Peru, was divided by
Grisebaeh, in IS-iS, into two separate genera :
to the former species,
originally describetl liy Kuuth as LisiantJius anomalus, he now gave
the name of Leiothaninus anomalus, designating the latter species,
first described in the ' Flora Peruviana' as Lmanthus calycof/onus, R.
and P., under the name of Symbolanthus cali/cogonus, Griseb. ; but
Don's name of .S". Fuvonu 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 th^ Peruvian species is here first given,
in order that Weir's plant may be compared with it.
