 Near L. adtrata Svr., but diffei-s from it by the mncli narrower and 

 longer fronds with smaller and broader pinnae ; also 

 allied to Liridsmja linearis Sw. (in KliNZE Farn- 

 krauter I. t. 16-1) and Lindsaija gracilis=Lindsaya 

 securi/olia Presl. (Kunze Famki-auter I., t. 85-1), in 

 the linear lanceolate simple pinnate fi'onds. Perhaps a 

 form of L. cnltraia. Sw.
