190 28. R RUDIS. 



Stem arcuate, rougli, angular, furrowed. Prickles nearly 

 equal, slender but strong, compressed-conical, from a slightly- 

 enlarged base, sabpatent, chiefly placed on the angles of the 

 stem and scarcely passing into aciculi. Aciculi, setce, and 

 hairs many, very short, nearly equal. Leaves quinate. 

 Leaflets rather concave, deeply and coarsely dentate-serrate 

 or almost lobed, hairy, and having a dull lurid appearance 

 above, pale with many hairs on the ribs and much greenish- 

 white felt beneath; basal shortly-stalked, obovate-lanceolate ; 

 intermediate stalked, obovate-lanceolate acuminate ; terminal 

 oval or elliptic-obovate, acuminate; petioles which are flat 

 above, and midribs with short hooked prickles beneath; 

 stipules linear-lanceolate. 



Flowering shoot from fuscous scales, slightly wavy, hairy, 

 setose, aciculate. Prickles strong, from large bases, declining 

 or slightly deflexed. Leaves mostly ternate. Leaflets much 

 narrowed below, acuminate, greenish- white and felted beneath. 

 Panicle narrow, leafy, aciculate, setose ; ujoper prickles 

 slender ; branches short, ascending, between racemose and 

 corymbose, few-flowered, mostly axillary; top corymbose. 

 Sepals ovate-attenuate, aciculate, setose, hairy, felted, often 

 leaf-pointed. Petals distant, oblong, white. Filaments 

 white. Anthers and styles greenish. Primordial fruit-stalh 

 about as long as or slightly longer than the reflexed sepals. 

 Nut ^-obovate; inner edge nearly straight. 



The sulcate stem, nearly equal and scarcely scattered 

 prickles, short and nearly equal aciculi, setae, and hairs, 

 coarsely serrate or even jagged leaflets, and strongly re- 

 flexed and usually leaf-pointed sepals, distinguish this bram- 

 ble from R. Eadula. It is separated from R. . Hystrix by 

 the felted under side of its leaves and the sepals being so 

 much reflexed from the fruit as usually to press closely 

 against the peduncle. Barely, especially when it grows in 

 deep shade, the felt on the leaves seems to be wanting, and
