2. HITHERTO UNDE8CRIBED SPECIES 



♦'Quercus microcarya 



A shrub, or a small tree sometimes 5 m. tall, with very smooth 

 branches and glabrous foliage. Leaves deciduous ; blades thin, 

 spatulate in outline, 5-10 cm. long, undulate or shallowly lobed, 

 gray-green above, yellowish green beneath, short-petioled, the 

 small bristles terminating the lobes early deciduous : acorns sessile, 

 less than 10 mm. long; cup deep saucer-shaped, 6-j mm. broad ; 

 nut globose-ovoid, often nearly one-half included in the cup. 



On granite outcrops, Little Stone Mountain, Georgia. 



Related to Q. nigra, but more delicate in all its parts. The 

 leaf-blades are relatively thin and more irregularly lobed, while 

 the very small acorns, always, as far as I have observed, less than 

 10 mm. in length, with their relatively deep saucer-shaped cups, 

 are very distinct from the larger fruit of Q. nigra with its very 

 shallow cup. The fruit is much smaller than that of any of the 

 species of the group to which this plant belongs. 



The original specimens were collected by the writer on Little 

 Stone Mountain, Georgia, September 11, 1894. Type in the her- 

 barium of the New York Botanical Garden. 



^ Quercus fusiformis 



A shrub 1.5-3 m - ta ^> w ^h slender or switch -like stems or 

 branches. Leaves persistent; blades leathery, oblong or ovate- 

 oblong, 3-5 cm. long, entire or sparingly spiny-toothed on the 

 twigs, gray-green and lustrous above, paler and scurfy-tomentose 

 beneath, slightly revolute, rounded or truncate at the oblique base, 

 short-petioled : acorns numerous, solitary or several on slender 

 peduncles; cup turbinate, 10-12 mm. high, gray; nut fusiform, 

 2-2.5 c m- long, long, acute, conspicuously striate, thrice surpass- 

 ing the cup. 



On arid limestone and granite hills, central Texas. 

 Quercus fusiformis belongs to the group formed by Q. minima, 

 Q. geminata and Q. Virginiana. It is most closely related to 



Q. Virginiana, but differs in the much elongated acorn with its 

 turbinate cup and fusiform nut. 



The original specimens were collected on Lacey's Ranch near 



M 



899- 



1900, and given to me by Professor W. L. Bray, of the University 

 of Texas. Locally known as Live Oak. Type in the herbarium 

 of the New York Botanical Garden.
