Rhamnus crocea Nuttall. 33 Hollyleaf Buckthorn. 



Range. — California (coast mountains from central to southern part of State). 



NAMES IN USE 



Hollyleaf Buckthorn (lit.). Evergreen Buckthorn (lit.). 



« Britton and Shafer (op. cit., 677) have adopted for this small evergreen tree the name Rhamnus ilki- 

 folia Kellogg, believing that Rhamnus crocea Nuttall is a shrub. Although Nuttall characterizes the latter 

 as "A much branched thorny shrub," I can not find but that otherwise his description fits the holly- 

 leafed buckthorn, which is often shrubby, as well as sometimes a small tree.
