 a foot long, the pinnules lanceolate - deltoid, glaucous- 

 green. Philippines. 



Litobrochia. See Pteris.

 differs from it in having marginal sori. The pinnae on 

 the barren fronds are broader than those on the fertile 

 fronds, which are developed in whorls.

 waved, deep-green. New Caledonia. G. 



L. gigantea. — A Tree-Fern with a short thick trunk, 

 bearing a crown of lanceolate-pinnate fronds 3 feet long, 

 light-green, the stipes black ; fertile fronds narrow with 

 linear pinnae; probably only a form of L. attenuata. South 

 Africa. G. 



L. lanceolata. — Fronds pinnatifid, 6 to 12 inches long, 

 | pinnae oblong- obtuse, slightly toothed, dull-green; caudex 

 ! tufted. New Zealand. G.

 clothed with chaffy scales. New Zealand, &c. G. 



Lygodium (Lygodictyon). — Elegant climbing Ferns, 

 with conjugate or palmate fronds. The veins are free, 

 extending beyond the margin, and there forming com- 

 pressed distichous sporangiferous spiculae. 



L. dichotomum (Jiexuosum). — A sturdy climber with 

 bipartite palmate fronds, the divisions 4 to 10 inches 

 long, ^ inch broad, rich-green; fertile fronds much con- 

 tracted. India, &c. 



L. japonicum. — In the way of L. dichotomum. but with 

 smaller pinnules, and less robust habit. Tropics. G. 



L. palmatum (fig. 723). — Fronds wiry, climbing in- 

 definitely; barren pinnae palmate, 2 inches wide; fertile 

 pinnae divided into small linear leaflets. May be grown 

 up a pillar in a cool house. United States. G. 



L. reticulatum ( For steri).— Fronds bipinnate, dichoto- 

 mously divided, scandent; pinnae broadest at the base, 

 bright-green. Polynesian Islands.

 nate; rachis zigzag, terminal pinnule lobed. A useful 

 plant for covering pillars. India, &c.

 by a reniform indusium, free or anastomosing veins, and 

 pinnate or compound fronds. They are generally easy 

 to cultivate, having a stout usually creeping caudex and 

 a robust root system.

 1 to 4 feet long; pinnae linear-lanceolate, deeply serrate, 

 bright-green; stipes light-brown. Ceylon.
