82 NORTH AMERICAN FAUNA. 



The type of this species is Dr. Edward Palmer's No. 129, from 

 Acapulco, Mexico, collected in 1894-95. To this species I would refer 

 specimens collected by Frank Lamb near Villa Union, State of Sinaloa, 

 January, 1893 (No. 428), and flowering specimens by W. C. Wright 

 from the head of Mazatlan River, January, 1889 (No. 1292), and also 

 those collected by J. N. Eose at Kosario. Sinaloa, July 10, 1897 (No. 

 1592), and July 22 (No. 1822). The latter two specimens are not in 

 flower and their reference here is attended with some doubt. The 

 seeds are larger and the pods less constricted between the seeds. Here 

 also belongs E. W. Nelson's No. 4303 from the Tres Marias, collected 

 May, 1897. I have tentatively referred to this species E. W. Nelson's 

 No. 2099, taken at an altitude of 480 meters, near Santo Domingo, State 

 of Oaxaca, June 18, 1895. It has similar pods, but is described as 

 being but 6 to 12 cm. high and has more bluntish leaflets. 



Dr. Palmer says this tree flowers in January, and is often used for 

 hedge fences. It differs from all other Mexican species which I have 

 seen in its white lanate banner. Its one-toothed calyx suggests E. 

 rosea, but in the latter the calyx is described as obliquely truncate. 



Phaseolus sp. 



Maria Magdaleua Island, May 26 to 28, 1897 (No. 4319). 

 Canavalia gladiata DC. 



A species of wide distribution, perhaps throughout tropical America. 

 May 3 to 25 (No. 4190). 

 Rhynchosia minima DC. 



A common Mexican species extending into South America and the 

 United States. May 3 to 25 (No. 4206). 



Rhynchosia precatoria(?) (H. B. K.) DC. 



This species has been reported from Acapulco and Panama. May 3 

 to 25 (No. 4179). 



Lonchocarpus sp. 



May 3 to 25 (No. 4310). 

 Ateleia ( ?) sp. 



Without flowers or named specimens for comparison it is impossible 

 to name this plant definitely. If it belongs to the genus Ateleia it is 

 perhaps A. pterocarpa, the only species known from Mexico. A shrub 

 or small tree 3.5 to 10.5 meters high. May 3 to 25 (No. 41S6). 

 Cassia emarginata L. 



Common in Mexico, South America, and the West Indies. May 3 

 to 25 (Nos. 4192 and 4297). 

 Cassia biflora L. 



Common in tropical America. May 3 to 25 (Nos. 4194 and 4196). 

 Cassia atomaria L. 



Common in Tropical Mexico and South America. Maria Magdaleua 

 Island, May 26 to 28 (No. 4321).
