and the midrib of pinnae and end of the pinnules furnished with the same bristly hairs. 

 Pinnae 40—50 jugate, close, sessile, regularly pectinate, at most an inch long, under J / 4 inch 

 broad cut down to tbe racbis into distinct, parallel, entire, erecto-patent pinnules under 

 half a line broad. Veins one central to each pinnule. Sori round, one at the base of 

 each pinnule, like tamariscinum in cutting and texture, but recoguisable at a glance by its 

 basal sori. 



Polypodium expansum Baker n. sp. (Polyp, dilatatum Hook, et Baker, Syn. Fil., 

 p. 365, ex parte, non Wallr.) Ist wahrscheinlich identisch mit Drynaria acuminata Brack, 

 in Brackenridge's Ferns, p. 47. Wir geben auch hiervon die vollständige Baker'sche 

 Diagnose : Rhizome short-creeping, i j 2 inch thick. Stem stout, naked, a foot long. 

 Lamina rhomboid, 3 feet long, a foot broad, narrowed to both ends, cut down' nearly to 

 the rachis troughout into simple, close, patulous, lanceolate, acuminate pinnae 1 — l 1 ^ inch 

 broad. Pinnae about 20-jugate ; wing of main rachis on inch broad. Texture membranous; 

 rachis and surfaces quite glabrous. Main veins rather distinct halfway to the edge ; areolae 

 fine, with copious, free, included veinlets. Sori round, not immersed, scattered irregulary, 

 3 or 4 between midrib and edge. 



Ausser diesen neu aufgestellten Arten sind noch folgende als neu für die polyne- 

 sischen Inseln zu bezeichnen: Davallia Emersoni Hook., Nephrodium inte 1 : 'medium Baker, 

 Vittaria scolopendrina Thwaites und Lycopodium serratum Thunb. 

 21. J. G. Baker. J)ie Farne, welche S. J. Whitmee in Samoa gesammelt hat. 2. Abthei- 

 lung. (No. 4.) 



Auch in dieser zweiten Abtbeilung finden sich eine Anzahl von Arten, welche für 

 die polynesischen Inseln als neu zu bezeichnen sind. Es sind dies Pteris Wallichiana 

 Agardh, Nephrodium hirtipes Hook und folgende neu aufgestellte Arten, von denen wir 

 ebenfalls, wie bei der ersten Abtheilung, die vollständige Originaldiagnose wiedergeben. 



Cyathea Whitmei Baker n. sp. Frond ample-, tripinnate. Rachises pale brown, 

 unarmed and quite naked. Pinnae oblong-lanceolate, l ] / 2 — 2 feet long, 8—10 inches broad. 

 Pinnules sessile, lanceolate, cut down to the rachis into ligulate deeply inciso-crenate tertiary 

 Segments i j fi inch broad. Veinlets 10—12 jugate, erecto-patent, deeply forked. Texture 

 membranous; both surfaces naked except numerous small pale bullate scales scattered on 

 the under side. Sori medial, 8—10 to a pinna. Involucre large, pale, campanulate, persistent, 

 the mouth nearly entire. 



Cyathea scabra, Baker n. sp. Frond ample, tripinnate. Rachises castaneous, glabrous 

 scaleless, scabrous with dense raised points. Pinnae oblong-lanceolate, l 1 ^ — 2 feet long, 8 — 10 

 inches broad. Pinnules sessile, lanceolate, 3 / 4 — 1 inch broad, cut down to the rachis into ligulate 

 deeply crenate tertiary segments 1 / 8 inch broad. Veinleits 10—15 jugate, deeply forked, 

 erecto-patent, distinct. Texture moderately firm; both surfaces and rachises nearly free 

 from hairs of scales. Sori 10 - 16 to a segment, ultimately filling the whole surface except 

 the tip. Involucre large, membranous, breaking up irregularly. 



Aspleniitm (Athyrium) oosorum, Baker n. sp. Fronds ample, quadripinnatifid. 

 Rachises naked, glossy, pale brown. Pinnae oblong-lanceolate, reaching a lenght of l 1 ^— 2 

 feet and a breadth of 8 10 inches. Pinnules lanceolate, 12—15 lines broad, cut down to a 

 narrow wing into deeply pinnatifid spaced lanceolate tertiary segments '/<> mcn broad. 

 Veins sparingly pinnate in the quarternary lobes. Texture moderately firm ; both surfaces 

 quite naked. Sori oblong, subcostal, half a line long, usually one only at the base of each 

 quaternary segment. Involucre firm, persistent, glabrous. 



Nephrodium (LastreaJ pubirachis Baker n. sp. Caudex erect. Sterns densely 

 tufted, pilose, clothed, especially in the lower half, with many large lanceolate pale brown 

 membranous scales. Frond oblong-lanceolate, bipinnate, 8—10 inches long by 4 5 inches 

 broad, not reduced at the base. Pinnae lanceolate, 2— 2'/ 2 inches long, V2— 5 /a iach broad, 

 sessile, cut down to the rachis into close ligulate sub-entire or toothed obtuse segments 

 under '/ 8 inch broad, the lowest pair of pinnae much deflexed. Texture moderatly firm, 

 the rachises pilose and rest of the surfaces naked. Sori copious, medial. Veins simple, 

 6—8 jugate. Involucre firm, persistent, glabrous.
