Anticlea Kunth. 



This genus was established on A. Sibirica and A. glaiica with 

 A. Mcxicana added as a doubtful species. A. Sibirica, the first 

 one mentioned, must be regarded as the type. It differs somewhat 

 from our American species, especially in the narrow somewhat 

 recurved petals and sepals and the narrow glands, but these differ- 

 ences are rather unimportant and do not warrant any generic 

 separation. The genus is characterized by a membranous coated 

 bulb, linear glabrous leaves, greenish or yellowish-white flowers, 

 withering persistent petals and sepals, which are adnate to the base 

 of the ovary and bear a single obcordate gland ; free stamens and 

 a partly inferior ovary. The species are :

II. Another segregation needed, I have found in the genus 

 Rubles. If Dalibarda is to be held distinct from that genus and 

 DucJicsnca from Fragaria, etc., certain species have to be removed 

 from Rubus as now understood, as both in general habit and the
