183 33. LOMAEIA, §§ PLAGIOCYRIA. 



33. L. Fraseri, Cunning. ; caud. elongated, stout, suberect, densely clothed 

 with linear dark-brown scales at the crown ; st. 4-C in. 1., strong, erect, scaly ; 

 fr. ovate-acuminate, bipinnatifid, 12-18 in. 1., 4-G in. br. ; pinnce linear-lan- 

 ceolate, the lower ones 2-3 in. 1., i-| in. br., cut down very nearly to the rachis 

 into linear-oblong mucronate slightly-toothed pinnl., their bases decurrent into 

 a pinnatifid wing to the main rachis with triangular lobes ; texture herbaceous ; 

 veins fine, the lateral ones of the pinnules usually once forked ; fertile fr. similar 

 in size and cutting. — Hk. Sp. S.p. 40. 7c. PI. t. 185. 



Hab. New Zealand. — Very dissimilar in habit to all the other species, combining a 

 frond like one pf our common Lastrem with the fructification of a Lomai-ia. 



34. L. voluUUs, Hk. ; fr. 20 ft. 1., scandent and twining ; pinnce distantly 

 placed, deltoid-ovate, 1 ft. or more 1., by neai-ly as broad, with a terminal pinnl. 

 and several opposite pairs, which are oblong, the largest 4-6 in. 1., 1 J-1^ in. br,, 

 narrowed suddenly to a long acuminate point, the upper part slightly toothed 

 and rounded at the base to a short petiole ; texture subcoriaceous ;' veins fine, 

 close-placed; usually simple ; rachis and both surfaces naked ; fertile pinnl. 

 narrowly linear, 4-6 in. 1., 1 in. or more apart at the base, with a broad con- 

 tinuous invol. springing from the edge of the leafy rib not more than a line wide. 

 —Hk. Sp. 3. p. 39. t. 150. 



Hab. Banks of the Kio Negro, Spruce, 1263 ; and since gathered by Dr. Spruce at 

 Napes (2,800), and by Appun in British Guiana (995). — This remarkable plant appears 

 quite to agree in habit with Blechnvm mlubile, of which it is probable it will ultimately 

 be shown to t« an abnormal Lomarioid form. 



§§_ Plagiogyria, Kunze. Base of the stipe suddenly dilated, fleshp,1/riqiMrms, 

 furnished with large spongy glands. Capsules with an oblique ring. Sp. 35-39. 



35. L. (Plag.) semicordata, Baker-; caud. short, erect ; st. dilated at the base, 

 winged below, erect, naked, 3-6 in. 1. ; fr. ovate-lanceolate, 1-2 ft. 1., 4-6 in. br. ; 

 pinnce numerous, spreading, linear, 3-4 in. 1., J-| in. br., finely serrated 

 throughout, the lower ones deflexed, the point narrowed gradually ; texture 

 subcoriaceous ; veins fine ; fertile fr. similar, but the pinnae more distant and 

 narrowly linear ; rachis strong, erect, naked. — Lomaridium, Presl. L. biserrata, 

 M. S L. Hk. Sp. 3. p. 19. Lomaria Fialhoi, F&e, 



Hab. Tropical America from Mexico to Peru, and South Brazil. 



36. L. (Plag.) adnata, Blume ; caud. short, stout ; st. 6-18 in. 1., firm, erect, 

 naked, dilated at the base ; fr. ovate-lanceolate, 12-18 in. 1., 4-6 in. br. ; pinnce 

 linear, falcate, the largest 3 in. 1., | in. br., the lowest equal to those next in 

 order, the lower ones narrowed at the base. below, -j in. apart, the point narrowed 

 very gradually and finely toothed ; texture subcoriaceous ; veins conspicuous ; 

 fertile fr. similar, but the pinnce more distant and narrowly linear ; rachis 

 naked, erect.— //£ Sp. S.p. 19. t. 147. 



Hab. Java and Khasia at 14,000 ft. — ^This and the preceding have the central pinna; 

 of the barren frond dilated, but the other three have them narrowed at the base and 

 distinct from one another, as in species 21-30. 



37. L. (Plag.) gloMca, Blume ; st. 1 ft. 1., naked, erect ; fr. ovate, 12-24 in. 1., 

 6-9 in. br. ; pinnce contiguous, erecto-patent, linear, 3-6 in. 1., \ in. or more br., 

 parrowed gradually and sharply toothed towards the point, narrowed on both 

 sides at the base ; texture coriaceous ; veins fine, subparallel, under surface 

 glaucous ; fertile fr. similar, but the pinnae distant and narrowly linear ; rachis 

 stout, erect, naked. — Hk, Sp. S.p. 22. 



Hab. Java and Khasia at 6,000 ft. ; gathered by Drs. Hooker and Thomson. — 

 Readily distinguishable by the silvery whiteness of the under side of the frond.
