CHARACTERS OF TRIBES AND GENERA. 341 



Type. Matonia pectinafa, P>. Br. 



Illust. Hook, and Bauer Gen. Fil., t. 43 ; Moore Ind. 

 Pil., p. 86 B. ; Hook. Syn. Fil., t. 1, fig. 8. 



OBS. This genus is founded on a unique and rare Fern, 

 as yet only known to be a native of Mount Ophir, in the 

 peninsular of Malacca. On account of the sori being 

 furnished with a peltate indusium I originally placed it in 

 Aspidece, but with which it has no other point of relation- 

 ship. With Gleichenia (with which I now associate it), it 

 not only agrees in habit but also in the character of the 

 sori, differing only in the sori being compital and indusiate. 



Sp. M. pectinata, E. Br. ; Wall. PL As. Ear. Ic., t. 16. 



198. STROM ATOFTERIS, Mett. (1861). 

 Gleichenia sp., Hook. Syn. Fil. t 1865. 



Caudex slender, subfrutescent, branching, erect. Fronds 

 in terminal tufts on the branches, and distant lateral ones 

 below the tuft, linear, about 12 inches in length, pinnati- 

 fidly pinnate ; segments sub-rotund, about an inch in 

 length, numerous, contiguous, adnate to the rachis, cori- 

 aceous and concave on the under side. Veins pinnate, 2 to 

 3 venules on each side, the lower forked. Sori punctiform, 

 solitary on each segment near the base. Sporangia 3 to 6, 

 mixed with numerous pilose hairs. Ring horizontal, broad. 



OBS. This genus is founded on a remarkable Fern, a 

 native of New Caledonia, of which there are specimens in 

 the Kew Herbarium, but those having arrived since the 

 failure of my sight I have consequently not been able to 

 examine them. It was first described as a new genus by 

 Mettenius in 1861. In the first part of the "Synopsis 

 Filicum," published in 1865, Sir William Hooker places it 

 in Gleichenia, with which it agrees in the sori being formed
