POLYANDRIA— MONOGYNIA. Cistus. 25 



Root simple at the crown, branching below. Sfeins one or more, 

 erect, simple, leafy, round, clothed, like the rest of the herbage, 

 with fine, soft, spreading hairs. Leaves op^oaiie, stalked, ellip- 

 tic-lanceolate, flat, 1^ inch long, single-ribbed, with many 

 straight veins j less sharply pointed than is represented in the 

 old wooden cuts, Stipulas linear-lanceolate, acute, rather con- 

 vex or revolute, not half so long as the leaves. Fl. solitary, on 

 short thick hairy stalks, opposite to each leaf on the upper half 

 of the stem. Bracteas none. Cal. rough, most hairy at the 

 ribs and margin. Vet. small, obovate, entire, pale yellow, very 

 fugacious, and occasionally wanting. Caps, large, triangular, 

 polished, hairy at the upper part of the angles, single-celled, the 

 receptacles being not at all prominent so as to form partitions. 

 Seeds numerous, pale, roundish. 

 The C. annuus of Clusius, Hist. v. !. 76, whose figure is repeated 

 in Gerarde, Lobel, &c., and copied in J. Bauhin, v. 2. 13, is more 

 like some states of the present plant than that for which it was 

 apparently intended, C.saZici/b/t«s. These figures perhaps mis- 

 led Mr. Hudson. 



**** Dwarf shrubs, with stipulas.
