Tranlator Types Pollinia

Translator types in the Genus Hoya

In attempting to find new relationships of structure in this genus I have attempted to group the translators and the caudicles (two separate structures, one above the other normally) into groups of similar structure. The data was taken from my years of study and accumulation of data on the Pollinaria of this genus.

Structurally I see, without defining the structures too narrowly, that that there are two divisions that can be seen in the translators (1) translators that do not extend out beyond the proximal end of the pollinia (2) those that do extend further outward. The second group (2) can be divided roughly into wide translators and more narrow from the front on view of this structure. Within this later grouping there is considerable variation in shape from long ovals, to drumstick or delta shapes. There is much integration of types. A third category is where the translator extends externally from the side of the retinaculum, Hoya darwinii Loher is prime example. (3) Some I have placed in this group may be due to the pollinium slumping down when removed from the anther pockets for study.
