66 BRITISH BOTANY. 



R. lutea, Lin. Wild Mignonette. — e.b. 331. l.b.s. 126. 



A. 12. C. 30. Lat. 50-58°. East. Alt. 0-100 yds. Tern. 51-47°. 



Root rather woody^ annual or biennial. Stems rigid, branch- 

 ing, reclining or ascending, diffuse, leafy, 1-2 feet higb. Lower 

 leaves oblong-obovate, narrow at the base, entire or trifid ; stem- 

 leaves bipinnatifid, rarely palmate, with linear, undulate lobes. 

 Flowers in more or less dense clusters, pale yellow. Sepals six, 

 spreading, not enlarging after flowering. Capsule rigid, oblong, 

 triangular, with three teeth. Pedicels of the fruit erect, much 

 longer than the short caducous bracts. 



Chalky fields. Bien. ; June-August. 



Var. gracilis. Ten. Plant slenderer than R. lutea. Leaves 

 trifid, with linear-lanceolate, mucronate divisions ; fruit enlarged 

 above, with spreading stigmas. — On rubbish at Wandsworth, near 

 the Steamboat-pier. 



R. sufFruticulosa, Lin.— e.b. 2628. l.b.s. 127, 127 b. 



A. 10. 



Stem erect, glabrous, round, hollow, with many prominent, 

 sharp ridges, branching above, leafy. Leaves pinnate, with linear- 

 lanceolate, entire, decurrent lobes. Flowers white, in lax elon- 

 gate clusters (the cluster is dense when in flower, but lax in fruit), 

 on pedicels scarcely longer than the linear-pointed bracts. Se- 

 pals 5-6, linear, acute, spreading. Petals twice as long as the 

 sepals, with a trifid limb and obtuse linear lobes. Capsule ob- 

 long, quadrangular, with prominent angles, twice or thrice as 

 long as the calyx, crowned with four triangular teeth. Seeds 

 punctate. 



Waste places, here and there. Qy. Naturalized? Annual or 

 bijEBniaL; .Tune-September. 



Grenier and Godron give R. alba, Lin., as a synonym of this 

 plant. They also quote Reichenbach, 4448 and 4449, as pictorial 

 representations of this species. Hence it may be inferred that 

 they unite R. suffruticidosa and R. alba. 



CISTACEtE, Juss. {part.) The Cistus Family. 



Perennial or annual, half-shrubby or woody or herbaceous 

 plants, with opposite (rarely scattered), entire leaves. Flowers 

 regular and perfect, in terminal clusters, rarely in umbel-like 

 cymes or nearly solitary. Sepals five, free, persistent, the two
