KNowLT(jN.] DESCRIPTION OF SPECIES. 49 



Loral !f>j. — Van Horn'.s ranch and vicinity, on South Fork of John 

 Day River, 12 miles west of Mount Vernon, Grant County, Oregon. 

 Coilected originally by C. D. Voy (Univ. Cal., Nos. 1796, 1796a). 

 Since collected by Maj. Charles E. Bendire (U. S. Nat. Mus., Nos. 

 2565, 2566, 2568, 2569, 2570), Dr. John C. Merriam in 1900 (Mus. 

 Univ. Cal., Nos. 838, 839, 841, 842, 848, 844, 847a, 849, 852, 859, 865, 

 872), and by F. H. Knowlton, in July, 1901 (U. S. Nat. Mus., Nos. 

 8999-9015).

XI, fig. 2, 1888. 



Leaves coriaceous in texture, narrowly lanceolate in outline, wedge- 

 shaped at base, slender!}^ acuminate at apex; provided with 4 or 5 

 pairs of alternate or subopposite lobes, which are deltoid or deltoid- 

 lanceolate in shape, usually sharp-pointed, but occasionally with the 

 basal ones obtuse and rounded; petiole very long and slender; midrib 

 moderately strong; secondaries usually at an acute angle, as man\^ as 

 the lobes and ending in their apices; intermediate secondaries few, 

 apparently craspedodrome; finer nervation not well retained. 



This species is now represented })y more than twenty-five more or 

 less perfect examples. The one shown in PI. VII, fig. 4, was figured 

 by Lesquereux under the name of Qacrcus ■pseudo-lyrata august iloha.^'' 

 As shown in Lesquereux \s figure, it appears to lack the basal portion 

 with the petiole, but this was covered by matrix, which has now 

 been removed, exposing the long, slender petiole. The other speci- 

 mens figured, as well as all but one or two of those now known, were 

 obtained in 1901. 



The first-mentioned example (PI. VI, fig. 6) is aliout 14 cm. long, 

 including the petiole, which is fully 4 cm. long. At the widest point 

 between the lobes it is only a little over 3 cm., while at the narrowest 

 point, which is near the middle of the blade, it is considerably less 

 than 1 cm. The still larger example, shown in fig. 6, must have been 

 15 or 16 cm. long and 6 cm. broad between the points of the lobes. At 

 the narrowest point it is about 2 cm. One of the smallest leaves is 

 shown in PI. VI, fig. 6. It is 9.5 cm. long, including the petiole of 

 about 1.5 cm. in length. The broadest portion between the lobes is 2 

 cm., and the narrowest only 7 mm. in width. 



The specimens representing this species are intimately associated 

 with the numerous leaves of typical Q. pseudo-lyrata, and it is hardly 



a This varietal name can not be retained, as it is preoceupieil liy Quercus nnc/iistilohn A\. Br., in 

 Ludgw. Palffiontogr., Vol. VIII, p. 103, PI. XXXVI, flg. 3, 1861.
