614. Cean. sanguineus P. N. Hook. Eat. 

 Shrubby, branches purple, leaves subsessile cun- 

 eate oblong serrate pubescent beneath, panicle 

 axillary glomerate, flowers crowded — regions 

 of Missouri and Origon, seen dry, shrub 3 feet 

 high. 



615. Cean. glandulosus Raf. ovalis Big. 

 Beck, Eat. ovatus Dec. intermedius Hook. fl. 

 interm. var. corymbos. Mg. Perennial '( stem 

 sulcate pubescent, leaves ovatoblong obtuse 

 some obovate, glandular crenate trinerve, pe- 

 tiols and nerves pubescent, panicle terminal 

 corymbose formed by lax umbels — Canada and

 C, virgatus by Hooker, leaves 1 or 2 inches 

 long, large flowers, peduncles calix and corols

616. Cean. velutinus Hook. fl. tab. 45. 

 Shrubby, leaves rounded elliptic coriaceous 

 glandular dentate trinerve, white tomentose be- 

 neath, panicles terminal thyrsoidal foliose at 

 Ijase — in the Origon Mts. not seen by me, adop- 

 ted from the good figure of Hooker, and I add 

 two others of his to complete this monograph. 



617. Cean. levigatus Hook. fl. diflers from 

 last by, quite smooth, panicle quite foliose, flow- 

 ers glomerate — found at Nutka by Mcnzies.
