Near P. rotundifolia LINN. ; but distinguishable from it by the ovate 

 acute leaves with much fewer lateral veins along which the leaves are white 

 reticulated. There is a species called P. atropurpurea FRANCHET (Journal 

 de Botanique IX. p. 372) which I could not examine. It may presumably 

 be different from our plant.
