Relhania; a genus of lh. class Syngenesia, order Poly- 

 gamia-Superflua. GENERIC CHARACTER. Calix: common 

 imbricate, oblong; scales oblong, scariose. Corolla: com- 

 pound rayed; corollets hermaphrodite, numerous, tubular 

 in the disk; females ligulate in the ray; proper of the her- 

 maphrodites funnel-form, with a five-cleft border ; of the 

 females ovate, oblong. Stamina: in the hermaphrodites; 

 filamenta five, very short ; anthera tubular. Pistil .- in the 

 hermaphrodites; germen oblong; style simple; stigmas two, 

 reflexed; in the females; germen oblong, curved in a little; 

 style simple ; stigmas two, curved back. Pericarp : none ; 

 calix unchanged. Seeds: solitary, angular, crowned with a 

 membranaceous calicle, which is many-cleft and jagged, both 

 in the hermaphrodites and females. Receptacle: chaffy. 

 Observe. This genus differs from Athanasia in having a ray; 

 from Leysera, in not having a feathered pappus ; and from 

 Osmites, in the ray producing perfect seeds. ESSENTIAL 

 CHARACTER. Calix : imbricate, scariose. Corollets : of the 

 ray very many. Seed-crown : membranaceous, cylindrical 

 short. Receptacle : chaffy. For the propagation and culture 

 of this genus, see Athanasia. These plants are all natives o 

 the Cape. The species are, 



1. Relhania Squarrosa; Cross-leaved Relhania. Leaves
