Affumes the name of glafiifolia from the fimilitude which 
the leaves bear to thofe of the IJatis tinftoria , or Woad, 
Glafium of the old Botanifts. 
In this plant we have an excellent example of the Folium 
decurrens and Calyx ficariofus of JLinn^eus; the leaves alfo 
exhibit a curious phenomenon, having veins prominent on 
both their fides ; the feales of the calyx are moreover diftin- 
guiffied by a beautiful filvery appearance, which it is difficult 
to reprefent in colours. 
It is a native of the Eaft, as well as of Siberia; flowers 
with us in July, in the op.cn border, and is readily propagated 
by parting its roots in Autumn, which are of the creeping 
kind : requires no particular treatment. 
Miller, in the laft 4to edition of his Dictionary, enume- 
rates a Cent, glafiifolia ; but his defeription in detail, by nb 
means accords with the 'plant.
