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. intermedins Hook. fl. 

 interm. var. corymbos. Mg. Perennial ? stem 

 sulcate pubescent, leaves ovatoblong obtuse 

 some obovace, glandular crenate trinerve, pe- 

 tiols and nerves pubescent, panicle terminal 

 corymbose formed by lax umbels — Canada and 

 Lake Champlain, a very distinct sp. my speci- 

 men is quite heterophylous, the name of Ova- 

 lis does not apply, blended with my Southern 

 C. virgatus by Hooker, leaves 1 or 2 inches 

 long, large flowers, peduncles calix and corols 

 white. Apparently not shrubby. This was 

 my Forrestia thyrsoides of 1808 but it is not 

 even a subgenus, unless the glandular leaves of 

 this and the 3 next appear to indicate one.

 Shrubby, leaves rounded elliptic coriaceous 

 glandular dentate trinerve, white tomentose be- 

 neath, panicles tenninal thyrsoidal foliose at 

 base— 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. differs from 

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

 ers glomerate— found at Nutka by Menzies. 



618. Cean. bicolor Raf thyrsiflora Esholtz 

 and Hook. fl. shrubby, branches angular, leaves 

 subsessile oblong trinerve, nerves pilose, glan- 

 dular serrate, panicle thyrsoidal base foliose—
