Welwitsch distinguished this as a species, and gave it a name in his 

 Herb. It had been raised to this rank V,y R. Brown, from specimens 

 collected in the Congo region by Chr. Smith, and his herbarium name 

 A. pterojnis has been quoted in books. The striking character which 

 suggested Brown's name is the bn)ad wing on the short stalk of the 

 pinnae, which also pa'^ses down the rachis.

Welwitsch observes that as the sori are not limited to the sinus, but 

 extend up the margins, even to the apex of the lobes, this species 

 exhibits a transition from Lonchitis to Pteris.

This is Pelhm geraniifoUa Fee with the rounded distinct indusia of 

 Cheilanthes. Welwitsch says that a true indusium is present, which 

 appears not to be formed from the edge of the frond ; this would 

 transfer it to the genus Pteris, where Kuhn places it, but it is, in my 

 judgment, a true Cheilanthen.
