Discussion
Aldina yapacanmsis Cowan, Mem. N. Y. Bot. Gard. 8: 108. 1053.
The large number of recent collections of this species has made it necessary to join one of my species with an earlier one, but there is some consolation in the fact that the range of variation in the species is now much better understood. There is not a single key character used to distinguish A. yapacanensis which will now serve to identify it. The size of the flower-parts is especially variable in flowers of different ages; petals and ovary stipes, which are relatively small in bud, elongate enormously during anthesis and maturation of the flower. The type material of A. macrophylla shows mostly very large leaflets, but these recent collections indicate remarkable variability in leaflet size and shape. The following previously unreported collections represent this species.
