This species, P. cernua, Franchet, P. deflexa, Duthie and 

 P. pinnatifida, Franchet, are very closely allied and perhaps not 

 all deserving of specific rank, but at present we prefer to keep 

 them separate. 



Wilson's 4036 is very similar in aspect, but the leaves are very 

 much more hairy and the calyx is farinose. 



P. muscarioides has, so far as the Kew material goes, almost 

 sessile anthers near the base of the corolla-tube, and the stigma 

 projects slightly from the mouth of the tube. P. cernua, in the 

 specimen examined, has the anthers attached near the top of the 

 tube, and the style is only about 1 mm. long. In Wilson's 4036, 

 which has been referred to P. dejlexa, Duthie, the anthers are 

 attached a little above the middle of the corolla-tube and are over- 

 topped by the slightly exserted style. Thus we have trimorphism 

 of the genitalia in this very distinct little group of Primula.
