over 3 mm.), and the leaves are broader for their length, much less 

 tapering at base. Leaves about 31 mm. long are about 10 mm. 

 wide. The venation appears to be normal ; the lateral veins leave 

 the midrib at an angle of perhaps 55 . (Figure i.)

 Fendleri. 



Southwest of Florissant, 1905 {Henderson & Ramaley). There 

 is a singular resemblance to the leaf which Lesquereux calls San- 

 talum americanum, but this latter is quite entire, and shows no 

 venation except the midrib. 



Quercus Ramaleyi sp. nov. 



Leaf about 42 mm. long and 17 mm. wide, apparently firm, 

 with prominent venation ; margins divided into low broad lobes, 

 their points directed apicad, and rather blunt, not mucronate, their 

 long outer margins convex. Similar to Q. Fendleri, but the lobes 

 somewhat less divergent and not sharp-pointed. In many respects, 

 the leaf recalls that of Myriea alkalina Lesq., but it is different in 

 detail, and the venation is that of Quercus. (Figure 2.)
