pubescent ; anthers longer than the filaments, prolonged into fili- 

 form tubes; drupe not seen. 



In sand, Florida to Louisiana. Spring; fruit ripe in the 

 summer. 



Certainly distinct from Gaylussacia diimosa, from which it dif- 

 fers in habit, size and leaf characters. The pubescence is always 

 diagnostic, the corolla is larger and much thinner than that of G. 

 dumosa, while the calyx- segments are longer and usually acumi- 

 nate. 



3. Gaylussacia nana (A. Gray). 

 Gaylussacia frotidosa var. fiana A. Gray, Syn. Fl. N. A. Ed. 2. 



2: Ft. I, 396. 1886. 



A low glaucous shrub I-4 dm. tall, spreading by underground 

 stems. Leaves leathery, the blades elliptic, obovate or nearly 

 spatulate, 2-3 cm. long, obtuse or minutely apiculate at the apex, 

 glaucous on both sides, becoming bright green above, prominently 

 rugose and sprinkled with amber-colored resin beneath, short- 

 petioled ; racemes few-flowered ; pedicels slender, puberulent when 

 young; calyx glabrous, 3 mm. broad, the segments triangular, 

 acute, about as long as the tube; corolla globose-campanulate, 

 3 mm. long, the segments ovate, acutish, longer than broad; fila- 

 ments short, glabrous ; anthers longer than the filaments, pro- 

 longed into slender tubes ; drupes subglobose, 6-7 mm. in 

 diameter, rather dry, glaucous. 



In sandy pine barrens, Georgia to Florida and Alabama. 

 March to April; matures its fruit in the summer. 



Easily distinguished from Gaylussacia frondosa, with which it 

 has been associated, by its very glaucous foliage and strongly 

 rugose and much smaller leaves, besides its peculiar underground 

 stems.

Gaylussacia tomentosa Pursh ; A. Gray. Syn. Fl. N. A. 2 : Pt. 

 1,19. As synonym. 1878.

 ton entose with brownish hairs. Leaves leathery, the blades 

 oblong or elliptic, often slightly broadest above the middle, 2.5-7 

 cm. long, obtuse and apiculate at the apex or sometimes notched, 

 brow n-tomentose on both sides, densely so beneath, short-petioled;
