PARRY — CEANOTHl'S. I«7 



to be cut for fuel, showing a dense cherry-red heart-wood, from whence 

 it has derived the common name of "red wood." Its inflorescence is 

 copious, on prolonged thryses, the flower of a light faded blue, the 

 forming fruit scarcely lobed, and strongly resinous coated. 



In a systematic point of view, special interest attaches to the species 

 from this locality first described by Nuttall as C. hirsutus. While eas- 

 ily recognized from the description in this, its original locality, it has 

 been confused in points farther north and south by an erroneous 

 reference to C. sorediatus, Hook. & Am. Being particularly anxious 

 to clear up, if possible, this confusion, the species has been traced as 

 far as practicable in its southern extension with the conclusion since 

 fully confirmed, that all the southern forms belong to C. hirsutus, and 

 while not as yet fully informed as to its northern range, I am of the 

 opinion that it does not overlap or mingle with the true C. sorediatus, 

 the character and range of which latter I am now able, as will be shown 

 farther on, satisfactorily to define. It must suffice at present to offer 

 the following notes on C. hirsutus as seen in its original locality: 



C. hirsutus, Nutt., Fl. N. Am., I., p. 266. Four to twelve feet in 

 height, branches spreading, rather slender, light brown on the older 

 stems, occasionally covered with small glandular warts, younger 

 branches strongly hirsute; leaves ovate to broadly cordate, petiolate, 

 finely glandular-serrate, dark green above with more or less hispid 

 pubescence, paler beneath with conspicuous triple and intermediate 

 veins, hispidly ciliate; flowers bright or light blue, inflorescence more 

 or less prolonged; fruit rather conspicuously crested, 4 mm. broad. 

 As seen in its southern range, extending into Lower California, it 

 occasionally assumes an arborescent aspect. According to the views 

 of Mr. Brandegee, C. arboreus, Greene, would represent the insular 

 form of this species, though few may be willing to accept his conclusions. 



Another typical Santa Barbara species is C. divaricatus, Nutt. This 

 is one of the most easily recognized species, varying in size from a low 

 bush to a medium sized tree, with light colored glaucous bark, rigidly 

 spinose branches, light green leaves, usually entire, but not infrequently, 

 especially on vigorous shoots, irregularly serrate, inflorescence diffuse, 

 flowers dull faded blue ; fruit orbicular, with scarcely any protuberances. 

 It may be here remarked that the swollen protuberances appearing as 

 lobes or crests on the back of the cocci are always most conspicuous 

 on the young forming fruit, which shrink away more or less at maturity. 

 The accessory intermediate appendages common in the Cerastes section 

 often persist as projecting horns.
