112 20. LINDSAYA, SCHIZOLOMA. 



Hab. Malayan islands. There is no specimen of this in the Hookerian Herbarium. 

 The pinnae are said to be very deciduous. 



41. L. (Schiz.) ensifolia, Swartz ; rhizome creeping, stout, paleaceous ; st. 6-9 

 in. 1., wiry, flexuose ; fr. 6-12 in. L, 3-4 in. br., with a linear-lanceolate simple 

 or pinnatifid point, simply pinnate below ; pinnae usually in numerous pairs, all 

 stalked, 1^-6 in. 1., J-l in. br., varying from linear-acuminate to lanceolate in 

 shape, only the sterile ones, which are broader than the others, a little toothed ; 

 texture herbaceous ; veins copiously anastomosing ; sori in a continuous marginal 

 line. Hk. Sp. \. p. 220. Gard. F. t. 62. Hk. & Gr. t. 3. S. Agatii, Brack, 

 t. 30. L. Griffithiana, Hk. Sp. \.p. 219. t. 68. B. L. pentaphylla, Hk. Sp. 1.

Hab. Hongkong, and 4,000 ft. in the Himalayas, southward to Queensland, and east- 

 ward to the Polynesian Islands, Mauritius, Madagascar, Natal, Cape Colony, and Guinea 

 coast. This has quite the general habit of Pleris cretica, and is very variable in size and 

 the number of pinnae. L. Griffithiana is an unbranched form. 



42. L. (Schiz.) macrophylla, Kaulf. ; st. 12-18 in. 1., strong, erect, polished ; .fr. 

 about 12 in. L, with an entire ovate undivided apex, about 6 in. 1., 2 in. br. ; 

 pinnce about as long but rather narrower, ovate-lanceolate, oblique at the base, 

 decurrent on a short petiole, not toothed ; texture between herbaceous and 

 coriaceous ; sori in continuous submarginal lines. Hk. Sp. 1. p. 220. 



Hab. Brazil and Guiana. The inner valve of the involucre is a membranous line, 

 and the edge of the frond is produced beyond the line of the sorus, and cannot be said to 

 be altered in texture. 



43. L. (Schiz.) Fraseri, Hk. ; rhizome slender, creeping, fibrillose ; st. 2-3 

 in. 1., slender, erect ; fr. 9-12 in. L, 1 in. br., simply pinnate ; pinnce in distant 

 pairs, the largest ^-f in. L, ^-f in. br., cordate-ovate, toothed above and some- 

 times deeply lobed at the base, the upper ones almost as broad as long ; texture 

 thinly herbaceous ; sori in a continuous marginal line. Hk. Sp. 1. p. 221. t. 70. B. 



Hab. Queensland. It is not at all unlikely that this is a small delicate variety of 

 L. heterophylla. 



44. L. (Schiz.) heterophylla, Dry. ; rhizome short-creeping ; st. 4-8 in. 1., 

 firm, naked, erect; fr. 6-12 in. L, 3-6 in. br., lanceolate or oblong-deltoid, 

 varying from simply pinnate, with large linear-lanceolate entire pinnce, to bipin- 

 nate, with erecto-patent branches, 3-4 in. 1., with oblong lanceolate blunt pinnl. 



in. L, in. br. ; texture herbaceous ; sori in continuous marginal lines. 

 k. Sp. 1. p. 223. 



Hab. Neilgherries, Ceylon, Hongkong, Malayan peninsula and islands. The pinnae 

 or pinnules of the barren frond are slightly toothed. L. cuneata, Willd., is this species 

 from the Mauritius. 



** Diellia, Brack. Sori not quite marginal, transversely oblong or linear, the 

 outer valve of the involucre membranaceous, similar in shape to the sorus, but the 

 frond on the other side usually produced beyond them and not altered in texture. 

 Sp. 45-48. 



45. L. (Diellia) pumila, Hk. MSS. (non Klotzsch) ; st. tufted, 1-2 in. 1., wiry, 

 blackish, polished ; fr. 4-9 in. L, -1 in. br., simply pinnate ; pinnce 4-6 lin. 1., 

 1-^-2 lin. br., ovate-rhomboidal, rounded at the point, slightly undulated, 

 auricled at the base on the upper side ; texture subcoriaceous ; veins immersed ; 

 sori transversely oblong, submarginal. Diellia pumila, Brack, p. 219. 



Hab. Sandwich Islands. A very distinct plant, with the habit of a large form of 

 Aspknium Trichomanes.
