edge notched towards their gradually-narrowmg point ; they are of a soft, 

 papery texture, and the line of sori (spore masses) is not interrupted till it 

 reaches the crenations (notches) of the outer third of the upper margin. —

A greenhouse species, of somewhat large dimensions, native of New 

 Caledonia and the Isle of Pines. Its ample fronds, 1ft. to IJft. long. Gin. 

 to 9in. broad, broadly triangular, and tripinnatifid (three times divided nearly 

 to the midrib), are produced from a stout, creeping rhizome (prostrate stem) 

 densely covered with narrow filaments ; they are borne on stout, erect, 

 chestnut-brown, polished stalks 6in. to 9in. long, and are of a leathery texture. 

 The sori (spore masses) occupy nearly or quite the whole margin of the lobes, 

 which are of a pecuhar shape, being broader at their summit than at the 

 base. — Hooker, Sjjecies Filicum, i., p. 213.

This greenhouse species has a very wide range of habitat, being 

 a native of Hong-Kong, and, according to Beddome, found at the foot of the 

 Sisparah and Carcoor Ghats, in Malabar ; it also occurs at an elevation of 

 4000ft. in the Himalayas, whence it extends, to Queensland, the Polynesian 

 Islands, Mauritius, Madagascar, Natal, Cape Colony, and the Guinea Coast. 

 In general habit it is much like the popular Pteris cretlca, and it is 

 very variable in size and in the number of the leaflets. Its narrow-spear- 

 shaped fronds, 6in. to 12in. long. Sin. to 4in. broad, simple (undivided) at 

 their summit and simply pinnate (only once divided to the midrib) below, are 

 produced from a stout, creeping rhizome (prostrate stem) of a scaly nature, 

 and borne on wiry stalks 6in. to 9in. long. The leaflets, all distinctly stalked, 

 are usually disposed in pairs and of various shapes, only the barren ones, 

 which are broader than the others, being toothed. The sori (spore masses) 

 are disposed in a continuous line on the margin of the fertile leaflets, 

 which are abundantly produced. L. Griffithiana is a simple-fronded form of
