for the first time visits a tropical country, the very wealth of the 

 material completely nonplusses him for a time. The region abounds 

 in orchids. Only the smaller forms were collected although many fine 

 large ones were seen. A botanist is at once impressed with the 

 luxuriance of the epiphytic growths. A hasty visit was also paid 

 to the Rincon Grande, where a number of plants were collected

Only two hours were spent at Cordoba, between trains, so that 

 only a most hasty and superficial collection of plants was made of 

 the flora of this most interesting tropical region.
