232 Ornamental SlJrubs. 



is a, native of the United States, ranging from the Caro- 

 Hnas to New England, though ordinarily not very freely 

 distributed. It is everywhere a low and much-branched 

 shrub with elliptic-oblong foliage, smooth above, but of a 

 rusty brown beneath, thick and almost leathery, retaining 

 its vitality late in the season, becoming in the South al- 

 most an evergreen. The flowers, which come out in April 

 or May, are pure white, on short pedicels, oblong-cylin- 

 drical, and always attractive. They mostly spring from 

 the axils of the leaves and are borne in one-sided racemes 

 that cover almost the entire bush. It grows but from one 

 to three feet high, and for best effects should be planted 

 in groups or in connection with other shrubs. 



C. angustifolia is sometimes referred to as a distinct 

 species, but may be more properly described as a variety 

 which is in some respects an improvement on the original 

 form. It has longer and more narrow foliage, and slightly 

 varies from the type in the shape and disposition of the 

 blossoms. These last are in recurved racemes of the 

 purest white, with an oblong-ovate corolla slightly con- 

 tracted at the mouth. They, too, are on short flower 

 stems, and borne at the ends of the branches, appearing 

 in April. C. crispa is one of its synonyms, though some- 

 times catalogued as a distinct form.

THIS is a monotypic genus of the EricacecB and, 

 though a beautiful plant, is not so widely dis- 

 tributed as its merits would justify. It was named 

 after the famous Empress of Palmyra who lived in the
