*** Vernation erect, acaulose. Fronds pinnate (Loxochlena). 

 L. punctulata (Sw.). 



OBS* This is a native of South Africa, and varies con- 

 siderably in the character of its fertile pinnae, some being 

 so contracted as to justify the species being placed in 

 Lomaria, while others are broad, and have distinct Blech- 

 noid sori. Scolopendrium Krebsii of Kunze, also a native 

 of South Africa, is considered by some to be a state of this 

 species ; it differs in the transverse soriferous vein not 

 being straight, but forming numerous acute angles pointing 

 outwards, the interior sides of the angles being sporangi- 

 ferous, thus facing one another as in the scolopendroid 

 genus Antigramma, which character led Kunze to refer it 

 to Scolopendrium. In the " Species Filicum " it is viewed 

 as a synonym of L. punctulata. But as living plants of 

 both forms have been under my notice for many years, and 

 as both have retained their respective characters, I am 

 therefore inclined to consider them as distinct species.
