gilded beneath. 
549. Genus ANTHELIS. 
The Genus Cistus of Linneus was a medley 
of 150 heterogenous species, the modern botan- 
ists in restoring Helianthemum of Tournefort 
overlooked the perfect identity with Helian- 
thus ! both meaning Sun flower. To avoid 
this equivocal name I changed it in 1812 in my 
Chloris Etnensis to Anthelis being a transpo- 
sition (flower of the sun) this correction is indis- 
pensable, Of this Genus 5 sp. have been des- 
cribed as North American, and with 5 others 
from Mexico and Brazil form a peculiar group 
or subgenus quite American ; Decandole calls 
this group Lecheoides owing to the similarity 
with Lechea , but if it is to become a Genus in 
future this derivation will not do. I am going 
to add several new sp. thereto and thus venture 
to call it Horanthes flowers of an hour. 
S. G. HORANTHES, sepals 5, external 2 
narrow, internal 3 margin scariose, petals 5 yel- 
low, stamens few 12 to 20, stigma capitate 
large sessile or subsessile, capsule glabrous uni- 
loc, 3 valve— small suflruticose plants, leaves 
opposite below, no stipules, flowers evanescent 
or petals fugacious. The H . tripetala of Mex- 
ico is probably a Lechea ! all our sp. are es- 
tival. 
550 Anthelis (Horanthes) podanisia Raf. 
erect pulverulent pubescent, stem virgate sim- 
ple, leaves adpressed linear cuneate acute mar- 
gin reflexed; flowers in axillary fascicles, or 
racemes, pedicels unequal, one terminal much 
longer, calix with 3 oval sepals, 2 linear equal, 
capsule oval equal to calix — on the Red River
