atus, Hoscblis hermaphroditis quadrifidis tetran- 
dris. Semina coinpressa alata membranacea, 
apice margine crasso coronata.—Obs. A singular 
genus, having a striking similarity with Eclipta L. 
Cenia Jussieu and Buphthalmum L. but different 
from either, and also from Calendula , to which 
Robin joins it. The name was an ancient one 
for some species of Buphthalmum. Raf. 
211. Mnesiteon Album Raf. Scabrum, ramis diffusis, 
foliis (alternis ?) linearibus integris, floribus gemi- 
natis. Raf.—Calendula 1. Rob. p. 439. Stem 
three or four feet high, leaves narrow with only 
one nerve : flowers small lateral and terminal, 
half an inch in diameter, entirely white both rays 
and disk, anthers grey, stigmas yellow ; seeds 
oblong blackish, the upper margin deep green. 
It blossoms in June, the branches are juicy, and the 
juice becomes black as soon as it comes in con¬ 
tact with the air ? This species has some analogy 
with Buphthalmum angustifolium of Pursh, which 
perhaps belongs here, and also with Eclipta 
erecta Wild, which is Verbcsina alba L. 
212. Mnesiteon album var. pumilum Raf.—Calendula 2. 
Rob. p. 439. Only four or five inches high, 
blossoming in April; probably a distinct species to 
which the name of M. pumilum may be given. 
€13. Mnesiteon luteum Raf. Pubescens, ramis divari- 
catis teretis, foliis oppositis serratis, floribus 
longe pedunculatis, discus conicus Raf.—Calen¬ 
dula 3. Rob. p. 439. This rises two or three 
feet and the flowers are entirely yellow. Strik¬ 
ingly different from M. album .
