This genus was established on A. Szdirica and A. glauca with 
A, Mexicana added as a doubtful species. A. Szdirica, 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: 
1. A. Srpirica (L.) Kunth, Enum. 4: 191. 1843; Melanthium 
Stbiricum L. Sp. Pl. 339. 1753; Zygadenus Sibiricus Kunth, 
Enum. 4: 192, as synonym.

II. Another segregation needed, I have found in the genus 
Rubus. If Dalbarda is to be held distinct from that genus and 
Duchesnea from Fragaria, etc., certain species have to be removed 
from Rudus as now understood, as both in general habit and the
