name in use 



Live Oak 



81 Commonly a low shrub throughout its mainland range, becoming a small tree only on the south-coast 

 islands. 



Quercus Macdonaldii Greene, a southern California shrub or small tree, considered by some authors a 

 distinct species, but by others treated as a phase of Quercus dumosa Nuttall, is perhaps best disposed of 

 as by W. L. Jepson (Silva Calif., 49, 1910), who believes this tree to be a hybrid between Quercus dumosa 

 Nuttall and Quercus engelmannii Greene. 



v W. L. Jepson (op. cit., 219) considers this specifically distinct and has proposed for it the name Quercus 

 durata Jepson, "Leather Oak." 



« W. L. Jepson (op. cit. 218) considers the Shrub Oak Quercus turbinella Greene (West-Am. Oaks, 37, 

 1889; 59, t. 27, 1890) a variety of the Shrub Oak, calling it Quercus dumosa var. turbinella Jepson, a dispo- 

 sition that seems proper. The range of this plant, as now known, is in northern Lower California and 

 near Campo, San Diego. 



In this sequence should be recorded the shrubby Sadler's Oak or Deer Oak, Quercus sadleriana R. Brown 

 Campst, which occurs in southwestern Oregon (top of coast mountains along old Wimer Road) and in 

 northwestern California (Crescent City Trail, Del Norte County). See Forest Trees Pacific Slope, 285, 

 fig. 126, 1908. 



** Most students of southern trees have long observed that Quercus cirginiana Miller has been made to 

 include a thin-leafed and a thick-leafed form. The type specimen on which Quercus virginiana Miller 

 was based has not been preserved. C. S. Sargent (Bot. Gaz.. LXV, 443, 1918) believes that from circumstan- 

 tial evidence it is safe to assume that the type of this species is the thin-leafed form, which is the most widely 

 distributed one and includes practically all of the large live oak trees met with. The leaves of this foru. 

 are only slightly curled on the border, while the thicker-leafed form has leaves that ave conspicuously 

 curled op. their edges. Otherwise the mature trees of both forms are alike in their Labit of growth, bark , 

 and fruit
