Part II. JASiONE—LEIOPHYLLUM. 237 



niola, is easily propagated by division or by seed, and produces 

 its flowers white, with a faint green tinge, in early summer. The 

 leaves rarely rise more than a few inches high, the flower-stems 

 from ten to fourteen inches. 



JASIONE -BXmxm^.—DwarfJ. 



Not a showy but an interesting and pretty little plant, suited for 

 the select rockwork. The leaves are in rosettes, very slightly 

 toothed, stem-leaves larger, waved, and with sharp teeth ; all the 

 leaves ciliate at the base. The heads of light-blue flowers borne 

 on stems from one to two or three inches high, are from half 

 an inch to three-fourths of an inch across. A native of the 

 Pyrenees ; increased by division. This plant is related to 

 Jasione perennis, but is more ornamental. 



JEFFERSONIA TSXS'SITUhK.—T'winleaf. 



A PLANT very little known in England, and, where grown, usually 

 regarded as merely a botanical curiosity ; but when planted in 

 very sandy peat associated with subjects like the Epimediums, 

 Rhexia virginica, and Spigelia marilandica, it becomes a pretty 

 spring flower, as well as interesting from its curiously paired 

 leaves. The flowers are white, with yellow stamens, about 

 an inch across, and freely produced when the plant is in vigorous 

 health. A good plant for peaty and somewhat shady spots 

 on rockwork, and in a minor degree for the margins of beds of 

 dwarf American plants, planted in sandy peat, and flowers some- 

 what about the same time as the Bloodroot, in early spring. 

 A native of rich shady woods in North America. If seeds 

 are saved, they ought to be sown a few days after they are 

 gathered ; but generally careful division of the root, in winter, 

 must be resorted to where it is desired to increase the plant. 



LEIOPHYLLITM BUXIFOLIUM.— .S"a»rf Myrtle. 



A NEAT and pretty tiny shrub, forming compact bushes from 

 four to six inches high, and dens'ely covered with pinkish-white 

 flowers in May, the unopened buds being of a delicate pink hue. 

 It is particularly suited for grouping with diminutive shrubs, 

 such as the Partridge Berry, the sweet Daphne Cneorum, the 

 tiny Andromedas, and Willows like S. reticulata and serpyllifolia,
