* H. a. 3 Sievers\\ t H. Sieversw 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 Z/athyrus tuberosus, both in colour and size ; and they smell 

 sweet. According to Pallas, it is much frequented by insects, especially of the 

 genus Meloe 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.
