CoLENSO. — On New Cryptogamic Plants. 455 



Ohs. A very neat little species, allied to G. marginata, 

 Col. (" Trans. N.Z. Inst.," vol. xviii., p. 241), but differing in 

 several characters. Its place and manner of growth, nearly 

 hidden among the close-growing and erect Aneura, is peculiar ; 

 and it is not easily detected. 



Genus 8. Chiloscyphus, Corda. 



1. C. involucrata, sp. nov. 



Plant creeping, 2in.-3in. long, 1-lJ lines broad, symmetrical, 

 regular, distantly branched ; light-green. Branches very few, 

 alternate, divergent, simple rarely sinuate, rooting largely at 

 stipules ; roots long, tubular, white, hyaline. Leaves nume- 

 rous, very close throughout, densely imbricate, decurrent, 

 broadly ovate-deltoid with apex truncate ; margins sub-sinuate; 

 tips 2-horned, a horn at each extreme angle, long, divergent, 

 broad, 4-celled transversely at base, the upper horn usually 

 longer ; sinus deep, sides sinuate, the centre (at base) notched. 

 Cells large, orbicular with beaded centres, and minute tri- 

 angular intermediate cellules ; cell-walls stout, conspicuous. 

 Stipules large, extending across stem, connate with leaves 

 below, 4-fid, each of the two inner lobes having a small lobule 

 or tooth on its outer margin. Fruit terminal on a short basal 

 branch ; sometimes two such branches are near each other on 

 the same side of stem. Involucral leaves large, connate, 

 spreading, and (with perianth) darker green, their tips lacini- 

 ate ; laciniae long, flexuous. Fruit-stalk slender, erect, ^in. 

 long ; capsule small, elliptic, blackish. 



Hah. Eooting, mostly hidden, among, and epiphytal on, 

 small caespitose Aneura polijmorplia, Col. {infra), on rotten 

 logs, low wet woods south of Dannevirke, County of Waipawa ; 

 1889 : W. C. 



Ohs. A neat species, pretty closely allied to C. spruceana, 

 Col. (" Trans. N.Z. Inst.," vol. xxi., p. 59). 



Genus 13. Lepidozia, Nees. 



1. L. retrusa, sp. nov. 



Plant small, single, sub-erect, lin. high (rarely above, 

 mostly under), 3-6 lines wide; main stem brownish; cells 

 parallelogrammic, pinnate (very rarely bipinnate), branches 

 alternate, distant, tips flagellate ; flagellae long, capillary, 

 flexuous, pale, with small scattered bundles of long white hy- 

 aline rootlets. Leaves numerous close imbricate concave, pale- 

 green their margins darker green, sub-quadrate, 4-fid; lobes ex- 

 tending one-third of leaf, broad, triangular, divergent ; margins 

 slightly sub-sinuate ; sinuses wide ; cells distinct, sub-quadrate- 

 orbicular, regular in size, guttulate, obscure. Stipules rather 

 distant, small, broadly ovate ; tips slightly 2-3-toothed ; cells
