cnneate, rouiuled at the apex, margin rather distautlj' toothed, each tooth 

 terminated by a deciduous gland. Heads of flowers one to three inches 

 long, forming when in bnd broadly ovoid cones at the ends of the branch- 

 lets, covered with imbricating, silky scales. Rachit stout, villous. Pe- 

 duncles slender. Calyx-lobes erect or incurved, triangiilar. Petals with 

 rather long claws, and very broadly obovate, deeply cucullate laminae, of 

 a bright deep blue color, as are the joedicels, calyx and stamens. Ovary 

 depressed, three-lobed, lobes tumid at the apex. California, William 

 Lobb.— Hook, in Bot. Mag. vol. Ixxxv, t. 5124, June 1 (1859). 



C. rugosus. Stems stout but pliable, prostrate, glabrous in age, the 

 growing parts cauescently puberulent: leaves coriaceous, J-H in. long 

 including the short petiole, obovate- or elliptic-oblong, aciite at both ends, 

 closely and salieutly spinulose-serrate, 3-uerved, finely rugose on both 

 faces, tomeutulose beneath: fl. pale blue or white, in a short nearly simple 

 raceme, the peduncle equaling the leaf. — Top of a high hill near Truckee, 

 June, 1890. Sovne. Doubtless a hybrid of which C. cu7ieaius is one of the 

 parents. Mr. Sonne suggests that C. velutinus may be the other. The 

 young leaves are subtended by triaugmlar-subulate stipules a line long. —

tCeanothus? airopurpureus'Rat. Shrubby, quite smooth, branches terete 

 spi'eading rigid dark purple, leaves subsessile oblong entire, lower acute, 

 upper obtuse, not triuervate, tip of petiole and base of main nerve often 

 bearded — I refer protem to this genus, a doubtful shrub of Florida, 

 found without flowers in Collins Herb, owing to the similarities of habit 

 with the last [C. virgatus] and next [C sanguineus] sp. but it may turn 

 out to be something very different perhaps an Ilex? or Bumelia? Leaves 

 just like the last in size, but entire or slightly erose, and petioles exceed- 

 ingly short.— Kaf. New Flora, iii, 56, 1836.
