TWO RARE ENDEMICS FROM NORTHEASTERN OAXACA 
AMONG other plants recently collected in northeastern 
Oaxaca, Mexico, were two interesting endemics. 
Oreopanax platyphyllum Marchal in Bull. Acad. 
Bruxelles, ser. 2, 47 (1879) 88. 
Mexico: Oaxaca, District of Choapam, Santiago Choapam, long. 
95°55’, lat. 17°20’, alt. 1000 m., May 13, 1939, Schultes & Reko 907 
(Econ. Herb. Oakes Ames No. 5833; Herb. Gray). 
Known apparently from only two other collections, 
Oreopanax platyphyllum, a member of the Araliaceae, 
is endemic to the District of Choapam in Oaxaca. In the 
original description, Marchal referred to the two collec- 
tions which were known at that time as follows: ‘‘Mexi- 
co, ad Jocatepec et Lobcoba, Liebmann nos. 17 et 18 
in hb. Haun.’’ No state was designated in the description, 
but these localities are in the District of Choapam very 
near the locality of Schultes & Reko 907. 'The Liebmann 
localities are often omitted from standard maps; it may, 
therefore, be helpful to note that they are situated as 
follows: Santiago Jocotepec, longitude 95 degrees 56 
minutes, latitude 17 degrees 83 minutes; and San Juan 
Lacova, longitude 95 degrees 55 minutes, latitude 17 
degrees 29 minutes. 
Besleria glabra ( Oersted) Hanstein in Linnaea 34 
(1865) 325. 
Mexico: Oaxaca, District of Choapam, San Juan Lalana, long. 
95°45’, lat. 17°25’, alt. 350 m., May 6, 1939, Schultes & Reko 7S4 
(Econ. Herb. Oakes Ames No. 7120; U.S. Nat. Herb.). 
Besleria glabra, a member of the Gesneriaceae, is also 
a very local endemic, known only from the District of
