CEANOTHUS OEEGANUS, Nutt. MSS. 

 Bot. Mag. t. 5177. 



This species was first detected by Douglas in the woods of Oregon, 

 frequent from the Blue Mountains to the sea, and was also found by 

 Nuttall and Tolmie ; introduced to this country through William Lobb 

 from the same locality; the flowers white, in copious lateral panicles 

 during the month of May. The plant is now rarely seen. 



GEANOTHUS PAPILLOSUS, Torr. & Gray. 



Bot. Mag. t. 4815. 



One of the discoveries of David Douglas, for the Horticultural Society 

 of London, though not introduced to this country until William Lobb 

 sent seed to Exeter, from which plants raised flowered in an open border 

 for the first time in June 1854. 



CEANOTHUS VEITCHIANUS, Hook. 



Bot. Mag. t. 5127; Fl. des Serres, torn. iii. 2nd ser. 1858, p. 171; Sargent, Silva of 

 North America, vol. ii. p. 43. 



A magnificent hardy shrub introduced from California through William 

 Lobb, and generally the most successful of the genus. 



Though closely allied to Ceanothus floribundus, C. papillosus, and C. 

 Lobbianus, it is distinguished by its foliage, and surpasses these in an 

 abundance of bright mazarine-blue flowers, and a glossy, almost varnished, 

 leaf -surf ace. 



C. thyrsiflorus shows a tendency to cross with other species and 

 produce natural hybrids ; several had been suspected, and Dr. Parry, 

 who long studied the Californian Ceanothus in the field, reached the 

 conclusion that C. Lobbianus and C. Veitchianus are hybrids of this 

 species. 



CEANOTHUS VELUTINUS, Douglas. 



Bot. Mag. t. 5165. 



This species was first found on the Eocky Mountains, at considerable 

 elevations, by David Douglas, but not introduced to cultivation until sent 

 home by William Lobb. 



A white-flowered shrub with singularly dark-green leaves, glossy from 

 an aromatic resin exuded in hot weather, the under side velvety with a 

 whitish down.
