After returning to the town of Oaxaca and despatching the col- 

 lections which I brought with me from the south coast, I made an 

 excursion to the Chinantla, which had been represented as being 

 particularly worthy of my attention. The district so called lies in the 

 mountains north of Oaxaca and comprises several Indian villages ; 

 it is intersected by several large rivers which empty themselves in 

 the Gulf of Mexico, measures about thirty leagues in length, and 

 from one to five in breadth, and produces nearly all the tropical 

 fruits cultivated in Mexico in addition to the Soursop ( Achras 

 mammosa ) which is rarely seen in other parts of that country, and 

 the " Palao" a species of Passiflora, having a yellow fruit three 

 inches in length and two and a half in diameter ; the pulp of this 

 being rather acid is chiefly used in making refreshments. 



The whole district of the Chinantla from its broken surface and 

 well wooded mountains offers a great variety of climate and vegeta- 

 tion, but from my visit happening near the end of the dry season 

 my exertions did not meet my expectations. Having returned to 

 Oaxaca and despatched my collections to Vera Cruz, I prepared 

 to resume my journey to Guatemala. 



The following plants collected in the state of Oaxaca have 

 flowered or been raised in the garden, viz. : 



Epidendrum diotum 



— cochleatum 



— virgatum
