MEXICO. State of Yucatan: near Izamal, Dr. Geo. F. Gau- 

 nter, no. 561 in part (hb. Field Mus.). Dr. Gaumer's specimens 

 correspond in every essential detail with the descriptions of this 

 species, and with material in the herbarium of the Field Museum 

 from the West Indies and from South America. This species 

 seems not to have been reported hitherto from Mexico or Central 

 America.

Phoradendron vernicosum Greenman, sp. nov. 



Glabrous throughout: younger parts more or less vernicose: 

 stems and branches terete; ultimate branchlets compressed 

 at the nodes: leaves lanceolate-oblong to ovate-elliptic, often 

 slightly oblique or subfalcate, 2 to 7 cm. long, i to 2.7 cm. broad, 

 obtuse or rounded at the apex, entire, narrowed below to a 

 subpetiolate base, 3~5-nerved: spikes sessile or essentially so, 

 i to 3 (rarely 5) in the leaf-axils, i to 2 cm. long; segments 2 to 

 5 (usually 4), 5 mm. or less in length, 6- 12 -flowered in the 

 staminate spike, 2-flowered in the pistillate spike; perianth 

 3-merous: berry ovate-oblong, about 5 mm. long, not con- 

 tracted below the calyx-limb, more or less glaucous; endocarp 

 distinct, ovate-oblong, 4 mm. long, 2 mm. wide, abruptly 

 acuminate. P. ftavescens, Millsp. Field Col. Mus. Bot. Ser. 

 i. 294 (1896) in part, not Nutt. MEXICO. State of Yucatan: 

 Izamal, 22 February, 1906, /. M. Greenman, no. 440 (hb. Field 

 Mus.), type; Silam, June, 1895, Dr. Geo. F. Gaumer, no. 876 

 (hb. Field Mus.); Chichankanab, Dr. Geo. F. Gaunter, nos. 1850,

The vernicose character of the young stem and leaves, the 

 short axillary inflorescences, the two-flowered segments of the 

 fertile spike and the distinctly acuminate endocarp well char- 

 acterize this species. The nearest affinity of P. vernicosum is 

 with P. Wattii Krug & Urban, from which it differs in having 

 relatively shorter and broader leaves, the fruit not constricted 

 below the limb of the calyx, and a smaller and distinctly acu- 

 minate instead of acute endocarp.
