MADE BY Aftt. W. TOOL IN MABAGASOAR. 415 



4-5 in. broad. Many upper pinna? simple, central lanceolate ; lowest 

 largest, subdeltoid, with lowest pinnule on lower side sometimes del- 

 toid and more or less piniiatifid. Ultimate segments ligulate-oblong, 

 cuneate at the base, £-1 in. long, 2-4 lines broad, deeply toothed at 

 the barren tip. Texture membranous. Both surfaces naked and 

 bright green, the main rachis castaneous. Veins fine, distinct, erecto- 

 patent, all except the uppermost forked. Sori running from the top 

 of the cuneate base to within a short distance of the tip of the seg- 

 ments. Involucre pale, broad, persistent, glabrous. 



Very distinct. Most like the West-Indian Pteris Jteferopfa/lla, 



Linn. 



P. pedata, Linn. 



A variety with free veining.

63*. P. (Litobrochia) platyodon, Baker, n. sp. Stipe (broken 

 away) grey-stramineous, naked, as is the rachis. Frond rhomboid- 

 deltoid, a foot long by rather less broad, simply pinnate. Pinnae 

 below the large caudate pinnatifid tip 5-(i on a side, linear, the upper 

 ones adnate, the lower shortly petioled, half a foot long, an inch 

 broad, irregularly repand with deltoid obtuse teeth that sometimes 

 reach halfway down to the rachis, and an acuminate entire tip. Tex- 

 ture subcoriaceous. Both surfaces green and naked. Veins fine, 

 distinct, anastomosing in copious, often pentagonal, areolae without 

 any free included veinlets. Sori continuous from the base nearly to 

 the tip of the pinnae following the undulations. Involucre narrow, 

 firm, persistent, glabrous, very distinct. 



LOMARIA ATTENUATA, Willd. Var. HETEROPHYLLA. 

 L. BORYANA, Willd. 



L. pubescens, Baker, n. sp. Fronds dimorphic, barren oblanceolate, 

 12-15 in. long, 2-3 in. broad at the middle, narrowed to both ends, 

 its grey puberulent stipe 2-3 in. long, cut down to a very narrow 

 wing into close lanceolate denticulate pinnae f inch broad, the central 

 ones \-\\ inch long, the lowest obtuse and little longer than broad. 

 Texture membranous. Both surfaces deep green, the lower one, 

 and especially the slender grey-stramineous rachis, finely pilose. Veins 

 distinct, erecto-patent, forked. Fertile frond pinnate with distant 

 ligulate-subulate erecto-patent pinnae 1-3 inches long, 1 1 . 2 inch broad. 

 Most like the Australian L. lanceolata, but pilose.
