Jfyce.] FLORA OP NEW ZEALAND. 223 



structure is that of L. spectabilis. Stickidia either thickly fringing the margin of fertile specimens, or springing from 

 the nerve, lanceolate, simple or multifid. Colour "dark purple" (Colenso); a dark reddish-brown when dry. 

 Our first specimens of this plant were received from M. Chauvin, who obtained them from New Holland.

1. Amansia (??) Marchantioides, Harv.; fronde horizontaliter expansa inferiore pagina radicante fla- 

 belliformi varie lobata prolincationibusque marginalibus ascendentibus extensa tenui-membranacea ecostata 

 transversim parallele zonata striis longitudinalibus radiantibus decussata hexahedre areolata, cellulis oblongis, 

 fructu . . ? 



Hab. Cape Kidnapper and Hawke's Bay, on tidal rocks, Colenso. 



Frond at first prostrate, emitting rootlets from the whole of the under surface, flabelliform, excentrically ex- 

 panding in patches an inch or more in diameter, deeply laciniate or pinnatifid, the lobes erecto-patent, crenate, irre- 

 gularly dentate, and finally lobed at the edges, very variable in breadth and in division ; the primary lobes emitting 

 secondary flabelliform frondlets, which lie over the margins of the first, until there results an intricate stratum of 

 imbricated fronds. In more advanced specimens the ultimate lacinias are destitute of rootlets on the under surface, 

 probably therefore erect, linear, elongate, crenate, dentate or pinnatifid ; the margin undulate, and the apices blunt. 

 Membrane thin, conspicuously areolated, with diverging, longitudinal, and subconcentric transverse stria?. Cells 

 oblong. 



Probably very different in aspect when fully grown. Our specimens are evidently immature. We think it 

 also probable that it will eventually be made the type of a separate genus, but are unwilling to found one on such 

 imperfect data.

 Probably some mistake. A. triangulare has not of recent years been brought from the southern hemisphere ; 



it is a common West Indian species.
