30 NEW SYLVA 



the var. sericea or B, chrysophyloides of fl. 

 Louis, with similar leaves, but silky silvery and 

 ffilded 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 Lecheoldes 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 suffruticose 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) pouanisia 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, 

 cap^sule oval equal to calix — on the Red River
