574 PROCEEDINGS OP THE AMERICAN ACADEMY. 



Randia Nelsonii. Stems sparingly armed, covered with a grayish 

 or reddish-brown bark, rather numerously dotted with lenticels ; the 

 young shoots pubescent: leaves thin in texture, obovate or subcuneate, 

 1.5 to 3 cm. long, two thirds as broad, narrowed at the base into a short 

 petiole, usually rounded, but occasionally slightly retuse, obtuse, or even 

 short acumiiiate-apiculate at the apex, soft-pubescent on either surface : 

 flowers axillary, solitary, sessile : calyx including the slender spreading 

 lobes not exceeding 5 mm. in length, canescent-pubescent especially on 

 the tube : corolla including the lobes 2.5 to 3 cm. long ; tube about 1.5 cm. 

 long, externally puberulent, internally pubescent in the upper half; lobes 

 oblong-ovate, obtuse, nearly glabrous. — Collected by E. W. Nelson on 

 the way from Juchitan to Chivela, State of Oaxaca, altitude 46 to 277 m., 

 1895, no. 2635. 



A species somewhat resembling B. Pringlei, Gray, but readily distin- 

 guished from it by the texture of the leaves, the infloresence, the longer 

 corolla, and shorter calyx-lobes. 



Eupatorium Conzattii. Glabrous throughout: stems herbaceous, 

 ancipitally compressed and subhexagonal, striate, reddish-brown : leaves 

 petiolate, oblong-lanceolate, 5 to 15 cm. long, 2 to 6 cm. broad, acuminate, 

 acute, obtuse or somewhat rounded at the base and slightly decurrent on 

 the (7 to 20 mm. long) petioles, crenate-dentate, distinctly 3-nerved from 

 above the base, conspicuously veined, pellucid-jDunctate : inflorescence 

 terminating the stems in a compound pyramidal panicle : heads 8 to 9 mm. 

 long, clustered at the tips of the branchlets in threes or fives, sessile 

 or short-pedicellate, 5-6-flowered ; involucre cylindrical ; scales imbri- 

 cated, 5-6-seriate, oblong, obtuse or rounded at the tip, distinctly nerved, 

 purplish or stramineous, the outer gradually shorter and darker: flowers 

 about 8 mm. long: achenes 4 mm. long, glabrous; pappus equalling the 

 corollas. — Collected by Prof. C. Conzatti in humid forests on the Cerro 

 del Chiquihuite, Colonia Melchor Ocampo, Cordoba, State of Vera Cruz, 

 altitude 1,300 m., 7 December, 1895, no 17. 



This species may be recognized readily by the 3-nerved prominently 

 veined i^ellucid-punctate leaves associated with the few-flowered cylin- 

 drical heads. In general aspect E. Conzattii resembles E. vanillosmoi- 

 des, Sch. Bip., but is easily distinguished from it by the venation of the 

 leaves. From E. tepicanum, Hemsl., which is said to have ovate-lance- 

 olate pellucid- punctate leaves, our plant differs in having herbaceous 

 instead of woody branches. 



Eupatorium leptodictyon, Gray, in "Wats. Proc. Am. Acad. xxii. 

 420. Excellent specimens of this characteristic species were collected by
