 In the second edition of the ' Synopsis Filicum,' in 1874, about 200 



tree-ferns are described as distinct species. Since that date upwards 



of eighty new ones have been found. 



Genus 8. MATONIA R.Br. 



M. sarmentosa, Baker, in Journ. Linn. Soc. XXIV, 256 (see Plate 

 XIV). Rachis slender, terete, with long internodes. Segments 

 3-4 from each internode, linear, rigid, glabrous, simple or forked, 

 4-5 in. long, in. broad. Veins indistinct, simple, or forked. 

 Indusium globose, rigid, superior, attached by a short central 

 stipe, splitting by circumscissile dehiscence, so as to leave a 

 patelliform persistent base. Sporangia 8-10 in a cluster, with 

 a short stipe and incomplete vertical ring. Niah, Sarawak, 

 Borneo, collected by Mr. Charles Hose in 1887, sent to Kew 

 by the Bishop of Singapore and Sarawak. 



This is the most interesting novelty that has been found 

 during the period which this paper covers. It has entirely the 

 indusium and sporangia of the old well-known Matonia pecli- 

 nata, on which this genus was established by Robert Brown,
