late inferior ones gradually shorter semiovate above on the 

 dichotomous veins especially towards the margin quite rough 

 with harsh raised points, the margin entire, fertile fronds 

 dwarf much shorter than the sterile ones and on a longer 

 stipes in proportion coriaceous rigid pinnated very obtuse 

 scarcely attenuated below, pinnae oval-oblong very obtuse 

 crowded, involucres broad. (Tab, Nostr. CXLIV.) —

Hab. Chile, E. B. Philippi. Chiloe, Cuming, n. 2. — Our specimens of this 

 plant collected by Philippi, kindly communicated by Dr. Klotzsch, and those of 

 Mr. Cuming, exhibit a very peculiar mode of increase by what may be called 

 sarmenta (runners). A frond, as it would appear, instead of taking a rather 

 lanceolate form and rising erect, becomes contracted and decumbent, and having 

 attained its full length, takes root at the extremity and sends up new fronds, as 

 we have endeavoured to show in our figure. Similarly changed fronds I have 

 remarked in L. lanceolafa, yet I have not observed them to be proliferous. Indeed, 

 our plant is too near some of the dwarfer forms of that species. Independent, 

 however, of these frondose runners, if I may so call them, the very short 

 stipites and the remarkable rough upper surface and margins of the frond (like a 

 delicate file), and the dwarf nature of the fertile fronds, will, if permanent cha- 

 racters, afford good distinctions. 



17. L. Spicant, Desv. ; caudex or rhizome stout subterra- 

 nean copiously rooting scaly towards the extremity, scales 

 mostly lanceolate brown, fronds tufted a foot to two feet and 

 more high, sterile ones more or less spreading subcoriaceous 

 lanceolate slightly acuminate attenuated below deeply pec- 

 tinato-pinnatifid nearly to the rachis, segments horizontal 

 approximate linear or linear-oblong subfalcate obtuse very 

 opaque entire, veins oblique forked extending nearly to the 

 margin, fertile fronds much taller upon longer stipites gene- 

 rally with the same outline or circumscription as the sterile 

 ones pinnated, pinnae 1-2 inches long falcate distant narrow- 

 linear acute almost apiculate, sori when young intramarginal 

 in age appearing to cover the whole under surface, involucre 

 pale-brown membranaceous. — Desv. in Berl. Mag. v. jj. 325.
