is exceedingly dense, brown and coarse. The follicles also 
are larger than is usual in the genus.”’ 
The reddish sap which exudes when the stems of this 
vine are broken is extremely bitter. A decoction made 
of the stems of Connarus Schultesi is said to be used lo- 
eally by the Chinantecs of the District of Choapam as 
a taenifuge. In this connection, it is significant that a 
species of Connarus is similarly employed by primitive 
peoples in various parts of Africa (Heckel & Schlagen- 
hauffen in Ann. Fac. Sci. Marseilles 6, fase. 2 (1897) 
1-26). 
LEGUMINOSAE 
Erythrina horrida DeCandolle Prodr. 2 (1825) 413. 
Mexico: Oaxaca, District of Ixtlin, Santa Marié Jaltianguis, long. 
96°32’, lat. 17°21’, alt. 2000 m., June 20, 1939, Schultes 644a. 
This species of Mrythrina is known only from the 
State of Oaxaca. Krukoff (The American species of Ery- 
thrina in Brittonia 8 (1989) 259) cites ten collections. 
However, none of these are from the northeastern part 
of the state where Schultes 644a was collected. In the 
District of Ixtlin, Hrythrina horrida is called sompantle. 
Erythrina mexicana Arukoff in Brittonia 3 (1939) 
309. 
Mexico: Oaxaca, District of Tuxtepec, Cerro Verde near San Felipe 
Usila, long. 96°34’, lat, 17°51’, alt. 300 m., April 19, 1939, Schultes 
& Reko 687 ; District of Choapam, near Rio Chisme, Santiago Yaveo, 
long. 95°41’, lat. 17°20’, May 30, 1939, Schultes & Reko 952. 
Erythrina mexicana, known from Mexico (San Luis 
Potosi, Guerrero) and Guatemala, has previously not 
been reported from Oaxaca where, in the Districts of 
Tuxtepec and Choapam, it is the commonest species of 
the genus. It is known by the Spanish names co/orin and
