494 MOUNT WILSON AND ITS FERNS, 



Genus, Todea. 



Todea barbara or australis. Growing at the sides, and in the 

 running waters, of the creeks, some of the trunks 6 feet high, fronds, 

 many of which are nearly covered on the lower side with orange- 

 colored sori, 8 to 10 feet long. 



Todea Fraseri. One of our handsomest ferns, seen to great 

 advantage at the Happy Valley, Waterfall Creek, where almost 

 every stratum of the sandstone rock, up to 60 or 70 feet above 

 the bottom of the creek, is covered with long rows, growing in the 

 greatest luxuriance, with fronds upwards of six feet long. The 

 rhizomes are frequently 2 to 3 feet high. Plentiful also in the 

 Cascade Creek. 



Todea hymenophylloides, a very beautiful membranous fern 

 2 to 2 feet 6 inches high, but not so plentiful as at Katoomba. 



Genus, Lomaria. 



Lomaria discolor, and Lomaria falcata. Both very plentiful, the 

 latter forming an elegant plant. 



Lomaria (new), which I take the liberty of calling umbellata. 

 It is a showy variety with creeping rhizome, found only in one 

 spot in Cox's Creek, 2 feet 6 inches to 3 feet 6 inches high. 



Lomaria elongata. Growing in great profusion in many places. 



Lomaria filiformis. In the Happy Valley and Cascade Creek, 

 where this fern and certain species of Hymenophyllum almost cover 

 the trunks of some of the trees. 



Genus, Gleichenia. 



Gleichenia dicarpa, Gleichenia flabellata. These are not so fine 

 nor quite so plentiful as they are nearer the coast. 



Genus, Polypodium. 



Polypodium australe, and Polypodium Billardieri. Both growing 

 very luxuriantly. 



Polypodium attenuatum. Found in the basaltic soil on the 

 slopes.
