182 33. LOMAIIIA, §§ PLAGIOGYRIA. 



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

 with linear davk-brown scales at tlie crown ; st. 4-G in. 1., strong, erect, scaly ; 

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

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

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

 a pinnatifid wing to the main racliis 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. 3. 2>- 40. Ic. PL t. 185. 



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

 frond like one of our comm6n Lastrew with the fructification of a Lomaria, 



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

 placed, deltoid-ovate, 1 ft. or more 1., by nearly as broad, with a terminal pimil, 

 and several opposite pairs, which are oblong, the largest 4-5 in. 1., lj-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 i'liiiol. springing from the edge of the leafy rib not more than a line wide. 

 —BL Sp. 3. p. S'J. t. 150. 



Hab. Banks of the Rio 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 Blechnum volubile, of which it is probable it will ultimately 

 be shown to be an abnormal Lomarioid form. 



§§ Plagiogyria, Kunze. Base of the stipe suddenly dilated, fleshy, triquetrous, 

 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-G in. 1. ; fr. ovate-lanceolate, 1-2 ft. 1., 4-G in. br. ; 

 pinnce numerous, spreading, linear, 3-4 in. L, 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. & L. Hk. Sp. 3. p. 19. Lomaria Fialhoi, Fee. 



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-G 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, \ in. apai-t, the point narrowed 

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

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

 naked, erect. — Hk. Sp. 3. p. 19. t. 147. 



Hab. Java and Khasia at 1-4,000 ft. — This and the preceding have the central pinnjc 

 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.) glauca, Blume ; st. 1 fti 1., naked, erect ; fr. ovate, 12-24 in. 1., 

 G-9 in. br. ; pinnce contiguous, erecto-patent, linear, 3-5 in. )., \ in. or more br., 

 narrowed 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. 3. p. 22. 



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

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