BOTANY OF THE GUAYAXA HIGHLANDS PART IV (2)

A single very immature flower bud was found to have escaped the ravages 

 of insects. From this an imperfect concept of the anthers was obtained but no 

 sign of caudae could be found, a character usually well marked in the genus. 

 Perhaps they would be present in mature flowers.
