XX. 2. THE DWARF CASSANDRA. 373 



is clothed with a grayish bark, with a few short leafy branches 

 near the top, and with umbels of drooping, snow-white or flesh- 

 colored flowers at or near the end. The branches are slender, 

 and covered with a pearly, sometimes reddish bark. The leaves 

 are on short petioles, narrow, lanceolate, much revolute at the 

 edges, pointed, glossy green above, of a pure glaucous or whit- 

 ish color beneath. The short, pearl-white flower-stems spring 

 from the bosom of ovate, concave, pointed bracts of the same 

 color. The short, acute, persistent segments of the calyx are 

 white, tipped with red. The corolla is five-angled, nearly glob- 

 ular, almost closing at the mouth, with the obtuse segments 

 revolute. A faint, rosy tinge is often spread over the whole 

 flower. The stamens are very short, with brown anthers, 

 which open in two terminal pores, and are tipped with short, 

 awl-like bristles. The round ovary terminates in a club-shaped 

 stigma. Flowers in June. It is found on the edge of Richards' 

 Pond, in Brookline ; on tussocks in a bog in Richmond, and 

 elsewhere. This plant, like others of its kind, may be prop- 

 agated by dividing the root or by layers. 



Several other species, which had been included in the genus 

 Andromeda, have been elevated by Don into new genera; 

 A. calyculata to Cassandra ; A. paniculata to Lyonia ; and 

 A. racembsa to Zenobia. Their great difference in habit and 

 appearance seems to authorize a change made on botanical 

 grounds. 



XX. 2. THE CASSANDRA. CASSANDRA. Don. 



A genus of two species of low shrubs, covered with a fine pu- 

 bescence, which makes them look as if sprinkled with dust. 

 The leaves are leathery and persistent ; flowers white. The 

 calyx is five-leaved, with two bracts at base ; the corolla oblong, 

 enclosing ten stamens, with anthers which terminate in tubes. 

 Both species are cultivated in Europe for their beauty. 



The Dwarf Cassandra. C. calyculata. D. Don. 



A low, leafy, evergreen shrub, from two to five feet high. 

 The bark on the principal stem and larger branches is very
