XXV. LEGUMINA ‘CEE: CALO’PHACA. 243 
& H. a.3 Sievérsii, H. Sievérsii Fisch., is a dwarf variety, very hardy, 
named by some as a species. H. S. 
An irregular, much-branched, rigid shrub, with a strigose grey bark, and 
leaves clothed with a whitish silky down. The flowers are numerous, resem- 
bling those of Zathyrus tuberdsus, both in colour and size; and they smell 
sweet. According to Pallas, it is much frequented by insects, especially of the 
genus Méloe Z., many species of which are peculiar to Siberia. It flowers 
freely from May to July, and, in moist seasons, later ; and, when grafted 
standard high on the common laburnum, it forms one of the most graceful 
drooping trees that can adorn a lawn.
