L. Macgillivrayi — Mac-gil-liv-ray'-i (Macgillivray's), Carruthers. 



The fronds of this species, native of New Caledonia and the Isle of 

 Pines, are 1ft. to l-|ft. long, triangular, bipinnate (twice divided to the 

 midrib), and borne on straw-coloured, naked stalks. The leaflets, nearly 

 1ft, long and lin. broad, are furnished with stalked pinnules (leafits) disposed 

 alternately (not opposite), of a leathery texture, and with both surfaces naked 

 and green ; their upj)er border is straight and the lower rather ascending. 

 The sori (spore masses) are disposed in a continuous line along the upper 

 and outer edge. In habit this species resembles L. Kirkii and some large 

 forms of L. guianensis. — Hooker, Symrpsls Filicum, p. 109. 



L. (Synaphlebium) media — Syn-aph-leV-i-um ; med'-i-a (intermediate), 

 B. Bra ion. 



This species, native of Tropical Australia and the adjacent islands, has 

 the habit of L. fiabellulata ; but its triangular fronds, Gin. to 12in. long, 

 bi- or tripinnate (twice or three times divided to the midrib), and borne on 

 flexuose (zigzag-bending), shining, pale stalks Gin. to 12in. long, are of thicker 

 texture. The pinna3 (leaflets), Jin. long and Jin. broad, have their lower 

 line nearly straight and the upper one rounded. The sori (spore masses) are 

 disposed in a continuous, marginal Hne. — Hooker, Species Filicum, i., p. 112.

L. (Diellia) Michleriana — Di-eF-li-a ; Mich'-ler-i-a'-na (Michler's), Eaton. 



A very curious species, native of the Cataract of Truando, New Granada, 

 with fronds Ift. to IJft. long, broadly spear-shaped in general outline, and 

 bt)rne on slender, elongated stalks of a slightly scaly nature ; they are pinnate 

 (once divided to the midrib) below, with leaflets oin. to oin. long and lin. 

 broad, the upper half linear, undulated at the margin. The sori (spore masses) 

 are nearly marginal, and ]mve the outer valve of their involucre (covering) 

 of the same shape, but the margin of the frond is produced beyond it and 

 unaltered. — Hooker, Synopsis Filicum, p. 113. 



L. (Isoloma) microphylla — Is-ol-o'-ma ; mi-croph-yr-la (small-fronded), 

 Sicartz. 



This greenhouse species, of medium dimensions, is a native of New 

 Zealand and Temperate Australia. Its fronds (Fig. 91), Gin. to IcSin. long,
