Spec. Char., Sfc. Leaves oblong-lanceolate, obtuse or ^TTX 64 



acute, and more or less rugose ; reticulately veined, 

 with undulated margins. Petioles short, hairy, con- 

 nected at the base, and sheathing the stem. Flowers 

 terminal, from 1 to 6, on short peduncles. Bracteas 

 sessile, leaf-like, pubescent, broad and concave at 

 the base, where they are connected, and terminating 

 in acute points. Pedicels short, and with the calyx 

 hairy ; calyx of 5 sepals. Petals 5 or 6, obovate or 

 wedge-shaped ; very much imbricate, more or less 

 crumpled. Stamens numerous, filaments smooth. 

 Style very short ; and stigma large, capitate, 5-lobed, 

 papillose. {Swt. Cist., 17.) A shrub about 3 ft. or 

 4 ft. high, and much branched ; the branches are erect, 

 and clothed with a brownish pubescence. The flowers are very large and 

 handsome, of a bright reddish purple, with a yellow spot at the base, above 

 which is a large dark velvet mark, surrounded with red, and slightly branched. 

 The petals are imbricate, and much crumpled. It is a native of the Levant ; 

 but when it was introduced into England is uncertain : it seems to have been 

 cultivated by Gerard under the name of Cistus mas angustifolius, " with 

 flowers of a purple colour, in shape like unto a single-flower briar rose, 

 having leaves very like those of sage, wrinkled somewhat like unto a cloth 

 new dried before it be smooth." It is rather tender; but, if planted near or 

 against a wall, requires no other protection. It flowers abundantly in June 

 and July, and is very ornamental. It grows very fast, and is easily propa- 

 gated by cuttings.
