KEYS TO THE FERNS OF BORNEO 
3. L. crispa Baker. 
North Borneo. 
Local. 
4. L. gracilis. 
Sarawak, Dutch Borneo. 
Malaya to New Caledonia. 
This is an epiphyte with filiform rhizome; D. 
concinna is terrestrial, with stout rhizome and clustered 
fronds. Because the two have been confused, statements 
as to occurrence and distribution are questionable. 
5. L. repens (Bory) Bedd. 
Common. 
Oriental Tropics. 
6. L. pectinata Bl. 
Sarawak, British North Borneo. 
Malaya. 
7. L. scandens Hooker. 
Sarawak, British North Borneo, 
Malaya. 
8. L. lancea (L.) Bedd. 
Common. 
Tropics. 
L. repens seems in some places to shade into 
L. pectinata ; and L. pectinata and L. scandens surely 
blend, and may be represented by fronds on a single 
rhizome. Finally, the latter two species are sometimes 
(but rarely) bipinnate, and then develop long stipes; I 
cannot distinguish such fronds of L. scandens from ample 
fronds of L. lancea. 
9. L. longissima Christ. 
• Dutch Borneo, British North Borneo. 
Endemic. 
10. L. impressa Christ. 
Dutch Borneo. 
Endemic.
