iqiq] SARGENT— north AMERICAN TREES 22 1 



leaves, like those of the other species of this group, probably show little evidence 

 of the prominent veinlets which are not conspicuous on them before early 

 summer. In collections of Texas plants C. Lhidheimerii and more frequently 

 C. laevigata var. texana have been confounded with C. reticulata. 



Seedlings raised at the Arboretum from seeds of a tree with rough, mostly 

 entire leaves growing at the Montezuma Well in central Arizona {Relider, 

 no. 537) have coarsely serrate leaves which are rough or nearly smooth above 

 on the same branchlet. 



From western Texas I have seen specimens of C. reticulata collected in 

 Uvalde, Kimble, Mitchell, Nolan, Callahan, Randall, Hartley, and Jeff Davis 

 counties. It ranges into western Oklahoma, and through southern New 

 Mexico to southern, central, and northeastern Arizona, and occurs on Cedros 

 Island off the coast of Lower California {Veatch, 1872, in Herb. Gray). 



Celtis reticulata var. vestita, n. var.— Differing from the 

 type in its more pubescent serrate leaves and more pubescent 

 petioles. Leaves broadly ovate, acute or acuminate at apex, 

 unsj-mmetrically rounded or subcordate at base, the margins 

 thickened, ciliate, and sharply but irregularly serrate, thick, dark 

 green and scabrate above, paler and coated below with short pale 

 pubescence with longer hairs on the slender midribs, primary veins, 

 and conspicuoulsy reticulate veinlets, 3.5-4.5 cm. long and 

 3-3.5 cm. wide; petioles densely tomentose, 4-5 mm. in length; 

 leaves on vigorous shoots acuminate, mostly cordate at base, more 

 coarsely serrate, rugose, and covered above with short white hairs 

 and more densely pubescent below, 6-8 cm. long and 4-4.5 cm. 

 wide, their petioles thickly covered with matted pale hairs, 8-9 mm. 

 in length. Fruit orange-red, 6-7 mm. in diameter. 



A small tree with a trunk 20-25 cm. in diameter and slender pubescent 

 branchlets, those of \dgorous shoots stouter and densely villose. 



Near Canton. Blaine County, Oklahoma, in low ground along the North 

 Fork of the Canadian River, D. M. Andrews, August 15, 191 5 (nos. 21, 49 type). 



Specimens of vigorous sterile branches collected by Palmer at Canadian, 

 Hemphill County, Texas, June 17, 1918 (no. 14109), may prove a distinct form 

 of this variety. The leaves are acuminate, obliquely cordate at base, coarsely 

 serrate, more pubescent below, 6-9 cm. long and 3 . 5-5 cm. wide; the petioles 

 and branchlets are densely tomentose.
