 axillary ones racemose its prickles many slender deflexed or de- 

 clining with many setae and aciculi, sep. ashy-felted hairy. — 

 a. fiisco-ater ^. Cokmanni Bab. — St. with a few aciculi and 

 setSB and scattered hairs. Pan. not felted. Pet. white. The 

 position of this plant is doubtful ; but it seems to be most allied

18. R. Sal'teri (Bab.); st. arcuate-prostrate angular furrowed 

 subfflabrous, prickles suhpatent slender compressed from a dilated 

 compressed base, 1. quinate. Its. thin coarsely and doubly patently 

 dentate green on both sides hairy only on the veins beneath, 

 term. It. broadly obovate cuspidate-acuminate subcordate, pan. 

 long lax hairy its ultra-axillary branches short few-flowered 

 corymbose patent its rachis wavy its prickles slender declining, 

 Sep. hairy felted erect-patent. — St. green, becoming quite gla- 

 brous, with a few aciculi and setse occasionlly. Lts. hard and 

 rough beneath. — a. Salteri; Its. lobed or doubly serrate, rachis

 Pet. white. — /3. R. calvatus (Blox.) ; Its coarsely dentate the

 lax pan. wavy branches subracemose and ascending the upper- 

 most corymbose and patent, sep. loosely reflexed. Many sunken 

 setoe on the panicle. Pet. pinkish or deep rose-coloured. — 

 These plants seem to be the extremes of one species. — Open

19. R. carpinifdlius (W. & N.) ; st. ered-arcuate angular stri- 

 ate with patent clustered hairs, prickles slender conical com- 

 pressed declining from a dilated compressed base, 1. quinate, 

 .ts. thin irregularly but finely serrate pilose above rather paler 

 or whitish and densely hairy beneath, term. It. obovate-acumi- 

 nate or cuspidate, pan. narrow racemose hairy setose its lower 

 branches axillary short few-flowered its prickles deflexed or de- 

 clining, sep. hairy setose loosely reflexed from the fruit. — R. G. 

 13. — St. forming a large lofty arch. L. with very fine but irre- 

 gular acute teeth remarkably directed forwards. Pan. often 

 nearly simple, cylindrical. Pet. white or reddish. — Open places

20. R. villicafUis (W. & N.) ; st. arcuate angular patently pi- 

 lose, prickles strong conical-compressed subpatent from a dilated 

 compressed base, 1. quinate. Its. thin dentate-serrate pale green
