Greene, Cal ac b 2:392: ''Tree oft 20 3

 branches few and open: Ivs oblg-oval; 

 com 3' Ig, including the %' petiole, and

 cronate at apex, the margin slightly but 

 very regularly glandular-crenulate:

 fr also the same except as to s'z>. be- 

 ing much larger. The tree here spouen 

 of, although receiving its best develop- 

 ment on Santa Cruz, is well known in 

 western Cal from Lake Co southward 

 along the Mt Diablo range, and in hb 

 specimens may, with some excuse be 

 referred, as it long has been, to Nut- 

 tail's R. crocea; but no one in the field 

 can confound the two. 1 sav. p the same

 there is a little doubt aboui its being 

 the plant described by the kite Dr. ICel- 

 log-g. But in view of their probable 

 identity, I dare not propose a new name 

 for what, if it be the same, has already 

 two by the same author, ihe other one 

 being R. ilicifolia."
