 ovate-rotund to broadly oblong, 2 to 3 mm. long, nearly or quite as

 (hb. John Donnell Smith, and hb Gray). This number was dis- 

 tributed in the exsiccatae of John Donnell Smith under the name 

 ''Citharexylum reticulatum, H. B. et K. ," from which species, however, 

 the one here described differs in having larger leaves disposed in 

 whorls of three, and a paniculate inflorescence with longer individual 

 racemes. 



Citharexylum Kerberi, sp. nov. 



Stem terete to subtetragonal, covered with a light gray or whitish 

 bark, glabrous; ultimate branchlets reddish brown, pubescent: leaves 

 opposite, obovate to elliptic-lanceolate, including the petiole 5 to 15 cm. 

 long, 2 to 6 cm. broad, rounded to short-acuminate and acute at the 

 apex, narrowed at the base into a o. 5 to i cm. long petiole, hispidulous 

 above, densely pubescent beneath, usually biglandular at the junction 

 of blade and petiole; midrib and lateral nerves somewhat sunken from 

 the upper surface and rather prominent beneath: inflorescence ter- 

 minating the stem and branches in elongated spicate racemes 13 to 18 

 cm. in length; rhachis hirsute-pubescent; bracts subulate, equaling or 

 somewhat exceeding the short pedicels, usually persistent: flowers 

 scattered, 12 to 15 mm. in length: calyx tubular, 6 to 7 mm. long, 

 subulately 5-dentate, pubescent on both surfaces: corolla salver- 

 shaped, about twice exceeding the calyx, puberulent at the base of the 

 lobes in the throat and in the upper part of the tube, otherwise 

 glabrous; tube 8 to 10 mm. long; lobes obovrate to obovate-cuneate, 

 3 to 4.5 mm. long, two-thirds as broad: perfect stamens 4, included, 

 the fifth stamen much reduced, often to a mere staminodium: ovary 

 and style glabrous: mature fruit not seen. MEXICO. Without defi- 

 nite locality, E. Kerber, no. 430 (hb. John Donnell Smith) This 

 species passes under the native name of "Aceitunillo." 



Citharexylum macradenium, sp. nov. 



Shrub or small tree?, glabrous throughout: branches 4-angled, 

 covered with a light gray or whitish cortex; ultimate branchlets 

 striate, reddish brown, deciduously atomiferous glandular: leaves 

 opposite or rarely subalternate, lanceolate to elliptic-lanceolate, 7 to 15 

 cm. long, 2 to 3.5 cm. broad, acute, entire, narrowed at the base into 

 a i to 2 cm. long petiole, minutely punctate, dark green above, paler 

 beneath, bearing at the base of the blade at its junction with the 

 petiole commonly 2 large elliptic-oblong swollen glands especially 

 prominent on the upper side of the leaf; lateral nerves arcuate, 6 to 9
