Central Paraguay, Morong (220). In dry soil about Asuncion. 

 December. 



The species here briefly characterized is nearly allied to P. Tarn- 

 berliki, Urban (known to me only by description), next which it 

 may be placed,^ but it has far smaller leaves, and comes from a 

 different region. 



In addition to the description given by Mr. Rolfe, it may be said 

 that the stems are 3 or 4 dm. in height. The corolla is violet, with 

 deeper purple stripes on the outside, having a deep purple base on 

 the inside, upon which rests a beautiful 5-pointed green star. It 

 spreads wide open rotately at anthesis. Seeds nearly black when 

 mature.
