 pinnate; leaflets 12 to 15 pairs, linear-lanceolate, granulate-roughened, 20 to 2S mm. 

 long, acuminate, crenate; flowers in panicles clustered at the top of the brandies; 

 flowers white; sepals 5, nearly orbicular, about 1 iniu. long; petals 5, oblong, obtuse, 

 2.5 mm. long, strongly veined; stamens 5, short; styles 3, short; fruit strongly 

 flattened and winged, nearly orbicular, slightly broader than high (6 mm. broad),

Collected by Mr. E.W.Nelson, at Oaxaca City, altitude 6,000 feet, April 6, 1895 

 (No. 2542); also by Rev. Lucius ('. Smith at Cuesta de E.jutla Nacaltepec, State of

 was also seen along his route to Tehuantepec. 



Three other species are credited to Mexico, two of which were originally described 

 as belonging to the African genus Smodhtgium. Engler, however, has very properly 

 separated them. The genus is new to the National Herbarium.

 Dr. Palmer reports that this is a very handsome tree. It is known to 

 the Mexicans under the name of "drago." It is perhaps nearest /'. 

 drago L. but differs in the dense pubescence 

 of the inflorescence, large flowers, larger and 

 paler leaflets, etc.
