t 

 Citharexylum punqatum, sp. nov. 



Shrub?: stem and branches terete, covered with a grayish bark; 

 ultimate branchlets subtetragonal, cinereous-puberulent: leaves ellip- 

 tic-oblong to subobovate, including the petiole i to 2 cm. long, 5 to 12 

 mm. broad, usually short acuminate or somewhat pungent-tipped, 

 entire or occasionally bearing i or 2 teeth on either margin, glabrous 

 on both surfaces, conspicuously impressed-punctate above, minutely 

 punctate under a lens beneath, narrowed at the base into a short 

 petiole: inflorescence terminating the stem and branches in short few- 

 flowered puberulent racemes, 1.5 cm. or less in length; bracts 

 minute, triangular, acute, shorter than the stoutish pedicels: flowers 

 2 to 6 in each raceme, 7 to 8 mm. long in anthesis: calyx tubular- 

 campanulate, 3 to 4 mm. long, sinuately 5-toothed, 5-angled in cross 

 section, ciliolate, otherwise glabrous: corolla subsalverform, 5 to 6 

 mm. long, externally glabrous, pubescent in the upper part of the 

 tube and in the throat; lobes oblong, about one-third the length of 

 the tube: stamens 5, equal, included; filaments adnate to the corolla- 

 tube: ovary and style glabrous; mature fruit drupaceous, slightly 

 oblong, 10 to 12 mm. long, purplish-black in the dried state; pyrenae 

 oblong, about 7 mm. long, deeply concave on the ventral or inner 

 surface, conspicuously corrugated or somewhat irregularly furrowed 

 longitudinally over the dorsal surface. BOLIVIA. Without definite 

 locality, Bang, no. 1917 (hb. Gray, hb. John Donnell Smith, and hb. 

 Field Mus.), distributed as ''''Citharexylum ilicifolium H.B.K. ," from 

 which, however, it differs in having smaller and entirely glabrous 

 leaves with an entire, not spinose-dentate, margin. The striking 

 impressed punctation of the leaves of C. punctatum serves as an 

 excellent diagnostic character. 



Citharexylum recurvatum, sp. nov. 



Stem terete, covered with a gray or grayish-brown bark ; ulti- 

 mate branches terete, compressed at the nodes, striate, glabrous: 

 leaves opposite, petiolate, lanceolate-oblong to subovate, including the 

 petiole 4 to 11.5 cm. long, 1.5 103.5 cm - broad, obtuse (rarely emar-
