ginate) to acute, entire, revolute-margined, narrowed at the base into 

 the petiole, dark green above, paler and minutely punctate beneath, 

 glabrous on both surfaces; midrib and lateral nerves rather prominent, 

 especially beneath; glands i to 4 at the junction of blade and petiole, 

 not conspicuous; petioles 0.5 to 2 cm. long, glabrous: inflorescence 

 terminating the stem and branches in simple rarely branched glabrous 

 racemes, becoming strongly recurved and i to 2 cm. in length; pedi- 

 cels persistent, 2 to 3 mm. long, jointed above the middle, equaling 

 or somewhat exceeding the minute subulate bracts: flowers small: 

 calyx tubular-campanulate, about 3 mm. long, shallowly sinuate, 

 minutely 5-denticulate, glabrous: corolla subequally 5-lobed: perfect 

 stamens 4, included: ovary and style glabrous: mature fruit an oblong 

 drupe, 5 to 7 mm. in length, bluish-black; pyrenae elliptic-oblong, 4 

 to 5 mm. long, 3 to 3.5 mm. broad, 2 mm. thick, smooth. C. villosum,

Citharexylum Schottii, sp. nov. 



Stem covered with a grayish bark and dotted with numerous len- 

 ticels; branchlets slightly 4-angled, striate, brownish, glabrous: leaves 

 opposite, petiolate, elliptic-lanceolate, including the petiole 4 to n 

 cm. long, t to 3 cm. broad, obtuse or submucronate-acute, entire, 

 gradually narrowed at the base into a slender petiole, glabrous on both 

 surfaces or very minutely hirtellous above, usually reddish-brown 

 beneath in the dried state, commonly bearing two glands at the junc- 

 tion of petiole and blade; petioles i to 2 cm. long: inflorescence a 

 terminal panicle; bracts subulate, equaling or slightly exceeding the 

 short jointed pedicels : flowers numerous: calyx tubular-campanulate, 

 during anthesis about 2.5 mm. high, sinuately 5-dentate, 5-angled in 

 cross section, becoming somewhat saucer-shaped in the fruiting stages: 

 corolla about twice as long as the calyx, externally glabrous or essen- 

 tially so, pubescent in the throat; tube exceeding the calyx, obconical; 

 lobes oblong-rotund, pubescent on the upper or inner surface, cilio- 

 late: fruit oblong-obovate, 5 to 7 mm. long, drupaceous; pyrenae 

 oblong, about 5 mm. long, the inner surface concave, the outer convex 

 and smooth or slightly furrowed towards the bidentate base. C. quad-

The species here proposed differs from C. quadr angular e, Jacq. in 

 its more profuse inflorescence, smaller fruit, etc. Superficially C. 

 Schottii resembles C. glabrum, Greenm., but from this species again it 

 differs in having the spicate branches of the panicle erect or ascend- 

 ing, and in having also a proportionately shorter corolla-tube, and the 

 lobes of the corolla glabrous or essentially so on the outer surface.
