144 DESCRIPTIONS OF N.Z. FERNS. 



arising from the veins all over the under surface of the fronds, linear or linear-oblong, 

 simple or forked. 



SUB-GENUS EUGYMNOGRAMMA (Yu-gym-no-gramma) 

 Has the veins free, and the under-surface of the frond not powdery. It includes 



GYMNOGRAMMA POZOI. (Gym-no-gram-ma Po-zo-i.) 



PLATE X., Ho. 1. 

 The typical form of this fern is found in the North of Spain, North Africa, the 

 Coasts of the Mediterranean and other warm parts of the Northern Hemisphere ; van 

 B, otherwise " ruta;folia," i.e., rue-leaved, in Australia, Tasmania, and New Zealand, 

 and a Chilian form, var. G " papaverifolia," i.e., poppy-leaved, with more deeply cut 

 foliage, is also recognised. The New Zealand plant was first gathered near Cape 

 Terawiti, by a Maori shepherd, who took it into Wellington, and it has since been 

 found near " the Brothers " lighthouse at the entrance to Queen Charlotte's Sound, at 

 D'Urville's Island, the Port Hills near Christchurch, near Oamaru, and in the 

 Rangitata Country at the back of the Canterbury Plains, at an elevation of 3000 feet. 

 It grows in crevices of the rocks, and as it is said to occur usually in company with 

 Nothochlsena distans, I think it is also probably overlooked by colle6lors. The late 

 Mr. T. H. Potts considered the Canterbury plant to be different from the Australian 

 one, and proposed to call it " G. alpina," and it is certainly a far larger and differently 

 cut form from that, of which I have seen specimens, from Australia and D'Urville's 

 Island, though otherwise similar. This fern has a short, stout, eredl, rhizome, crowned 

 by a tuft of from three to twenty or more fronds, sometimes six inches high. Stipes 

 long, thin, yellowish and hairy. Rachis the same. Frond oblong, pinnate. Pinnae 

 far apart, short, stalked, fan-shaped, and more or less deeply divided into linear 

 divisions radiating from the stalk. Texture thinly coriaceous ; colour dull green. 

 The plant is quite unmistakeable, as its whole surface, both above and below, is 

 densely clothed with soft white hairs. Sori in lines radiating from stalks of pinnae, 

 brown. It is easily cultivated, requiring little moisture in any form. It is also called 

 " G. ruteefolia," " G. papaverifolia," " G. subglandulosa," " G. Alpina," and 

 " Grammitis rutaefolia." 



GYMNOGRAMMA LEPTOPHYLLA. (Gym -no-gram -ma lep-to-fil-la.) 



PLATE XVI., No. 6. 



This most lovely Httle plant, with only two others, is placed by the botanist. Link, 

 in a separate genus, under the name of " Anogramma," because they are annuals. 

 G. Leptophylla is very widely distributed, being found in the Azores, Madeira, the 

 Canary Islands, Jersey, Barbary, the Shores of the Mediterranean, Abyssinia, Cape 

 Colony, Persia, the Neilgerries, Australia, Tasmania, and the Andes from Mexico 

 southward to Ecuador, as well as in New Zealand. In the Colony it is rare, and getting
