 P- cereifera, Seem, in Bot. Herald, p, 182. t, 32. — Nomen vernaculum 

 Panamense, " Palo de A^elas." 



■ The geographical range of this remarkable plant appears to be very 

 limited, I found it in the central parts of the Province of Panama, 

 and no other traveller seems to liave noticed it in any other country.

 msertis, foliis petiolatis aliis simplicibus ovato-oblongis vel cuneato- 

 lanceolatis aliis trifoliolatis, foliolis ovato-oblongis utrinque attenuatis 

 integerrirais, petiolo communi superne anguste alato vel nudo, co- 

 roUge virescentis lobis undulato-crispis, fructu angulato tuberculato.

 This tree appears to be common ia the Tierra Caliente of Southern 



Mexico. According to Hernandez, it is found in Yauhetepec ; accord- 

 ing to Desvaux, in Guaxaca ; and according to Humboldt and Bon- 

 pland, in Campeche, at Gonacatepic. I myself have seen Mexican 

 specimens in Herb. Hook, from Schiede (no. 1207J and Coulter; the 

 latter had collected them at Zinapan,
