plant is eighteen feet high, eighteen feet wide, twelve feet deep 
(2. e. from back to front), covered with thousands of the beautiful 
thyrsoid flowers, so that the leaves are hardly visible. C. rigidus 
blossomed about six weeks ago; C. dentatus is now in full flower ; 
C. papillosus is just coming into flower; C. azureus will not 
blossom before August.” 
Dxscr. Our young plants are’ two and a half feet high, 
scarcely half the height they may be expected to reach; harsh, 
rigid, and very much branched, with the dranches opposite, 
straight, copiously leafy: at the internodes, or setting on of the 
leaves and branchlets, are two to four stout, sharp-pointed, large, 
smooth, brown warts. Leaves invariably opposite, on very short 
petioles, nearly sessile, spreading, subrotund or subcuneate, ob- 
tuse or retuse, concave above, glossy, as seen under the lens 
impresso-punctate ; the margin beset with rather distant, short, 
spiny teeth, pale beneath, and minutely reticulated ; the areole 
deep and pubescent. Unméels, rather than corymbs, lateral or 
more rarely terminal; the rachis from which the short rays 
spring short and fleshy. Flowers of a rich purple blue ; in other 
respects exactly resembling those of Ceanothus verrucosus, figured 
in our last number, Tab. 4660.
