562 PHANER0GAM1A. 



polymorpha. Calyx very tomentose externally with whitish wool, tur- 

 binate, five-lobed. Petals and stamens deep red; the former a little 

 pubescent externally. Ovary deeply immersed in the bottom of the 

 calyx, three-celled, its summit only free. Fruit unknown. 



This is surely distinct from M. polymorpha, however polymorphous 

 that may be. The stout veins of the leaves, so salient underneath, 

 the bullate upper surface, and the rusty or ochre-coloured wool 

 of the lower surface, along with the subsessile flowers, at once dis- 

 tinguish it. Few specimens were gathered. Those of Gaudichaud's 

 collection are, I believe, destitute both of flowers and fruit.
