plant, it is now recognised as simply a variety of L. virescens. — Hooker, 

 Synopsis Filicicm, p. 106. 



L. caudata — cau-da^-ta (tailed). A variety of L. trapeziformis. 



L. COncinna — con-cin'-na (neat), /. Smith. 



A pretty species, native of the Philippine Islands and Borneo. Its fronds, 

 6in. to 12in. long, fin. broad, and simply pinnate (only once divided to the 

 midrib), are produced from a short-creeping rhizome (prostrate stem) and 

 borne on erect stalks Sin. to 4in. long and of a wiry nature. The leaflets, 

 which are of a soft, papery, and somewhat transparent texture, are very 

 blunt on the outer edge, and the upper ones are very closely set together, 

 but not overlajDping. The sori (spore masses) are disposed in a continuous 

 or somewhat interrupted line along the upper edge, which is slightly notched. 

 — Hooker, Species Filicum, i., p. 205, t. 61b. 



L. (Schizoloma) COrdata — Schiz-ol-o'-ma ; cor-da'-ta (heart-shaped), 

 Gaudichaud. 



This species, of very peculiar appearance and dwarf habit, native of the 

 Malayan Peninsula, where it is said to be rare, is totally distinct from all the 

 other members of the genus, inasmuch as the fertile and the barren fronds are 

 completely dissimilar in every respect. The fertile ones, which rise altogether 

 above the others, measure from 3in. to 6in. in length ; they are usually linear 

 (very narrow), entire or forked, or sometimes divided into three long, narrow 

 leaflets, on which the sori (spore masses) are disposed in a continuous, 

 marginal line. The barren fronds, on the contrary, are quite entire (undivided), 

 somewhat heart-shaped, 2iu, to oin. long, and lin. to l^in. broad. Both 

 kinds are of a leathery texture, are produced from a short-creeping rhizome 

 (prostrate stem), and are borne on slender, erect, wiry stalks, which are 

 longer in the fertile than in the barren ones. — Hooker, Species Filicum, 

 i., p. 219, t. 66a. Beddome, Ferns of British India, t. 299. 



L. CUltrata — cul-tra'-ta (shaped like a plough- coulter), Siuartz. 



A very elegant species, also known in gardens as L. Lohhiana, native oi 

 the East Indies, Java, Ceylon, Luzon, and the Philippine Islands ; in the 

 Himalayas it ascends to 4000ft. ; it has also been found in the Neilgherries
