CENTAUREA _glastifolia_ calycibus scariosis, foliis indivisis integerrimis decurrentibus. _Lin. Syst. Veg. p. 787._ _Gmelin Sib. 2. p. 83._ CENTAURIUM majus orientale erectum, glasti folio, flore luteo. _Comm. rar. 39. t. 39._ [Illustration: 62] Assumes the name of _glastifolia_ from the similitude which the leaves bear to those of the _Isatis tinctoria_, or _Woad_, _Glastum_ of the old Botanists. In this plant we have an excellent example of the _Folium decurrens_ and _Calyx scariosus_ of LINNAEUS, the leaves also exhibit a curious phenomenon, having veins prominent on both their sides; the scales of the calyx are moreover distinguished by a beautiful silvery appearance, which it is difficult to represent in colours. It is a native of the East, as well as of Siberia; flowers with us in July, in the open border, and is readily propagated by parting its roots in autumn, which are of the creeping kind: requires no particular treatment. MILLER, in the last 4to edition of his Dictionary, enumerates a _Cent. glastifolia_; but his description in detail, by no means accords with the plant. [63] ~Fragaria monophylla.
