2. L. Oreopteris (Presl) ; rhizome thick short, fronds pinnate, 

 pinnae linear-lanceolate pinuatifid glandular beneath gradually 

 decreasing from about the middle of the frond to near the root, 

 lobes oblong flat, clusters marginal. //. F. 14. E. B. 1019. 

 N. 187. Fronds remarkably narrowed downwards, rising in a

 lateral veinlet. 



3. L. Filir-mas (Presl) ; fronds lanceolate subbipimiate, pinnae 

 linear-lanceolate lowermost pair rather smaller than the second, 

 pinnules oblong blunt or acutish serrate (not spinulose) attached 

 by their whole width or often connected below, clusters near the 

 midvein. E. B. 1458. N. 198. Fronds only slightly nar- 

 rowed downwards and the lowest pinna of considerable size, 

 rising in a circle from a tufted rhizome. Stipe and rachis
