pilose-pubescent, bearing one or more narrow, glandular, cadu- 

 cous bractlets : calyx obconic, pilose-pubescent, the divisions 

 about 4 mm long, entire or nearly so, reflexed after anthesis : 

 petals nearly orbicular, 5~6 mm broad, the claw at the base broad 

 and short : stamens normally 10, 4-5 mm long, the anthers pur- 

 plish : styles usually 2, surrounded at the base with pale hairs : 

 fruit globose, 7 mm -i cm in diameter, red or yellowish green with 

 red cheek, ripening the last of September or early in October, 

 the cavity about 3 mm in diameter, surrounded by the calyx lobes 

 and remnants of the filaments : nutlets mostly in pairs, occa- 

 sionally single, very thick-walled and hard, 6-8 mm long, 3-4 mm 

 measured dorso-ventrally, the ventral faces nearly plane and the

Cratczgns tetrica is a common species on the limestone hills about Nashville, 

 Tennessee, and is related to C. sinistra above proposed and to C. engelmanni, 

 Sargent, 1. c. It may be distinguished from the former by its greater size, 

 larger leaves, round fruit and earlier period of ripening. From the last named 

 species it may be recognized by the broader and more abruptly narrowed leaves, 

 more persistent and harsh pubescence of the foliage and inflorescence, smaller 

 flowers (i.5 cm or less in diameter) and more floriferous corymbs. C. berberifolia 

 T. & G. , 1. c, differs from the species just described by having narrower leaves 

 with cuneate bases and flowers with more numerous stamens. 



The type material, consisting of flowers and fruit from the same tree, is pre- 

 served in the Biltmore Herbarium. — C. D. Beadle.

Quercus boyntoni n. sp. 



A shrub i~5 m tall, usually growing in large clumps or occa- 

 sionally with the aspect of a small tree with a short trunk less than 

 jdm m diameter, common on Lookout Mountain at elevations 

 between 250 and 300 meters, near Gadsden, Alabama. Leaves 

 obovate in outline, 5-9 cm long, i.5~4 cm broad, with 3-5 small 

 obtuse lobes above the middle, but usually near the summit of the 

 blades or nearly entire, the apex obtuse, cuneate or narrowed 

 from the lower lobes to the base and prolonged into short petioles 

 5 mm -i cm long ; they are tomentose at the time of unfolding,
