of the Santa Inez Mountains, back of the city of Santa Bar- 

 bara. It presents, with its naked stem, and rough, almost 

 black bark, the aspect of a plum tree. But C. cuneatus, 

 which abounds at lower elevations on the same mountains, 

 is always in bushy clumps, its stems when old being covered 

 with a smooth, ash-gray bark. Moreover, the C. cuneatus, 

 even in its milder climate of the lower altitude is several 

 weeks later in its flowering, than the kindred species of the 

 higher summits. The very able and discriminating botanist 

 who discovered C. macrocarpus, named it well; the fruits 

 being about twice the size of those of the allied species. 



Of the following I have seen nothing hitherto, except flow- 

 ering branches, which always come to us named C. cuneatus. 

 which it certainly is not. From the description it must be 

 distinct from C. macrocarpus, and should doubtless bear that 

 name, in our herbaria, which the discoverer of the species 

 gave to it. I shall copy, for the assistance of our southern 

 correspondents, to whom the valuable and rare book may 

 not be accessible, the account given by Mr. Nuttall himself, 

 and printed by Torr. & Gray in the Fl. N. Am.

 serrulate, glabrous above, minutely tomentose-canescent be-

 nute protuberances at the angles.
