29-4 FERNS OF FIJI. 



Trichomanes maximum, Bluine. — Two varieties, one with tufted 

 stipites, the other with a creexnug rhizome, witli dwarfed dimorphic 

 fronds attached. 



Dlcksonia muJiiccana, Blume, var. inermis, Baker. — Differs from 

 the type, whicli is only known in Java, by the absence of prickles 

 \j on the rachises. Momitains of Namosi, Viti Levu, at 1500 feet 

 above sea-level, Home, 841 ! " Stipe 6 feet long and an inch in 

 diameter ; frond triangular in outline, 12 feet long, 10 feet broad at 

 the base." — Home. 



19''\ DicKsoNiA INCUKVATA, Bcikef, n. sp. — Frond 6-lQ feet long, 

 including the stout castaneous naked stij)e, deltoid, tripinnate, quite 

 glabrous and scaleless, moderately firm in texture, the rachises of all 

 grades bright brown below, pale brown on the upper side of the frond, 

 I the main one with a few small pricldes. PinuiB oblong-lanceolate, 

 the lower ones 1^-2 feet long. Pinnules lanceolate, the fullest- 

 developed ones 1-1 i in. broad, cut down to the rachis into oblong- 

 rhomboid deeply pinnatifid free sessile tertiary segments, whicli are 

 produced and parallel with tbe rachis on the upper side at the 

 base, cut away cuneately on the lower side. Veins fine, copiously 

 pinnate in the tertiary segments, with ascending forked veinlets. 

 Sori placed at the base of the ultimate sinuses, incurved, with a 

 deep persistent cup-shaped glabrous indusium. Forests near the 

 source of the Yaseri river, in the southern part of Viti Levu, 

 at an elevation of 1000 feet above sea-level, Home, 971 ! The stipe 

 and rachises are two distinct colours, dark chestnut-brown on the 

 back, pale brown on the face, and the two colours do not blend into 

 one another, but are bounded by a sharp line. Allied to the com- 

 mon American D. cicutaria. 



Davallia hijmenophijlloidcs. Baker. — " This very pretty Davallia 

 I found in two places in Fiji, in densely wooded mountains in 

 1 Vanua Levu, between Waiwai, Savusavu Bay, and Lomaloma, and 

 Viti Levu on the loamy banks of streams, near Navasi saw-mills. 

 In the latter station it was associated with D. Bhuneana, Hook." 

 — Home, 636 ! D. hymenophylloides has not been found x^i'eviously 

 nearer Fiji than New Caledonia. D. Blumeana has been gathered 

 several times in iSamoa, and once in Fiji, by Mr. Cairns. 



Davallia stolonifcra, var. acutifolia, Baker. — A curious new 

 variety, with narrow deeply pinnatifid pinnas, nearly an inch long, 

 narrowed gradually from the base to an acute point. On trees on 

 the tops of the mountains near Namosi, Viti Levu, and other 

 stations in the same island, in a region where the rainfall reaches 

 150 inches in a year. Home, 815 ! 



16.''' Adiantum Hoenei, Baker, n. sp. — Stipites tufted, 6-8 in. 

 long, glossy, nearly black, with a coating of small dark linear palere 

 near the base, glabrous, as are the rachises. Lamina deltoid, 

 1 about half a foot long and broad, the lower pinnae with 1-2 branches, 

 the other three or four simply pinnate, the texture firm, both 

 surfaces glabrous, the lower slightly glaucous. Segments con- 

 tiguous, oblong-rhomboid, akout f in. broad from top to bottom, 

 ^-f in. diameter oi)X)osite the rachis, the lower shortly petioled, the 

 upper ones subsessile, the inner margin parallel with the rachis,
