A tree, the branchlets stout, nodose, gray, lenticellate, the younger parts tomen- 
tellous. 
Leaves 9 to 17-foliolate, the rachis fulvescent-tomentose, terete, 10 to 20 cm. long. 
Leaflets coriaceous, the petiolules terete, tomentose, 2 to 3 mm. long, the blades 
ovate to oblong, rounded at the base, rounded-obtuse at the apex, 2.5 to 6.5 cm. long, 
0.9 to 2.5 cm. broad, pilosulous or glabrescent, the costa and veins deeply immersed 
above, beneath pubescent-tomentose, reticulate, the costa and veins ferruginous- 
pubescent and prominent. Stipules acutely triangular, about 4 mm. long, hairy, 
caducous. 
Racemes numerous, paniculate at the ends of the branchlets, 6 to 8 cm. long, the 
rachis tomentose; bracts at the insertion of the racemes triangular-acute, pubescent, 
about 2 mm. long, caducous. Peduncles and pedicels densely 
ferruginous or fulvous-pubescent, the former very short or want- 
ing, the latter 2 to 4 mm. long; bractlets at the base and near 
the apex of the pedicel very small, orbicular, fulvous-pubescent, 
caducous. Calyx campanulate, subacute at the base, distinctly 
5-toothed, densely fulvous-pubescent, the carinal tooth longer, 
the 2 vexillar teeth connate into a rounded lobe. Petals deep 
pink; standard suborbicular (broader than long), subbilobulate 
and plicate at the base, more or less emarginate at the apex,

Type collected in Campeche, Mexico, by Houstoun. 
SPECIMENS EXAMINED: 
Mexico: Near Iguala, Guerrero, flowers, August 11, 1905, Rose 9380; young 
fruits, Pringle 10338. Izamal, Yucatan, flowers, 1895, Gawmer 996. 
British Honpuras: Near Toledo, in forest, young fruits, January 15, 1907, 
Peck 600. 
GuaTeMALA: Near Santa Rosa, Department of Santa Rosa, alt. 1,000 meters, 
flowers and young fruits, July, 1892, Heyde & Lux (J. D. Smith, no. 3281). 
Honpuras: Between El Chaparral and Meambar, road from Comayagua to 
Puerto Cortés, February 24, 1898, Niederlein (vernacular name ‘‘ masicaarén’’). 
These specimens differ from the original description in the larger number of leaf- 
lets and their very variable size. The inflorescence is a typical aphyllous panicle, 
like that of ZL. subglaucescens Mart., notwithstanding which neither of these two 
species belongs to the section Paniculati.
