206 TREES AND SHRUBS. 



tree ; and it is due to the late Thomas Volney Munson (1844-1913), the distinguished viticulturist of Denison, where 

 it is very common on his land south of the city, that it is now possible to add it to the Silva of North America. 1 



i NOTES ON HICKORIES. 



This species, known formerly only from the valley of the Brazos River in Texas, has been found by Mr. George M. Brown on 

 the Arkansas River near Van Buren in the extreme western part of the state of Arkansas, and by Mr. G. H. Kellogg at Arkansas 

 Post at the mouth of the river. This interesting tree probably occurs therefore at other places on the Arkansas River in Qkl " 



Carta cordiformis, Wangenheim (Hicoria minima of Sargent's Silva N. Am. & Manual of the Trees of N. Am.). 



A form of this tree with broad leaflets may be distinguished as — 

 Var. latifolia, n. var. 



Leaves from seven- to nine-foliate, from 2.5 to 4 decimetres long, with slender petioles pubescent early in the season becom' 

 glabrous ; leaflets oblong-obovate to oval, acute, acuminate or rounded at the apex, coarsely serrate, villose above and hoarv 

 tomentose below when they unfold, at maturity thin, yellow-green and nearly glabrous on the upper surface, pale and somewhat 

 pubescent on the lower surface, the terminal leaflet acuminate and symmetrical at the base and often from 2.5 1 

 long and 1 decimetre wide and raised on a petiolule from 1 to 1.2 centimetres in length, the 1 

 unsymmetrical at the base, short-petiolulate, those of the upper pair often 1 decimetre long and frc 

 those of the other pairs gradually decreasing in size, the lowest not more than 7 centimetres long s 

 wide. Aments of staminate flowers from branches of the year and of the previous year, pedunculate. Fruit subglobose but some- 

 times a little longer than thick, 1.5 centimetres in diameter, opening by narrow winged sutures to the middle ; nut rounded at 

 the ends, distinctly four-lobed, especially at the base, slightly ridged below the apex between the lobes, puberulous, from 1.6 to 



A tall tree in woods, with close pale bark and slender orange-colored branchlets.

The leaves of the extreme form of this variety look very unlike the leaves of the common form of the Bitternut, with leaflets 

 not more than 2 centimetres wide, but trees with leaflets varying from narrow to the broadest of this variety occur in different 

 parts of the country. The pubescence of the variety is much denser than that on the common Bitternut, but the pubescence of 

 this species varies greatly on different individuals and cannot be depended on as a specific or varietal character. The lobed and

rowed and rounded at the apex, gradually contracted below into a thick short stipe-like base, L 

 mahogany color m drying, from 5.5 to 6 centimetres long and about 3.5 centimetres in diameter ; involucre from 8 to 9 milli- 

 metres thick, splitting tardily to the base by one suture, the others opening usually for less than one-third of their length; nut 

 acuminate at the ends, compressed, prominently four-angled to below the middle or nearly to the base, light-colored, from 4 to 

 4.o centimetres long, 2.5 centimetres wide and 2 centimetres thick, the shell from 2.5 to 3 millimetre, in thickness ; seed com- 

 parahvely large, of good flavor.
