CLIFTONIA PECTINATA, Haw. 



Gen. Char. Frond stipitate, formed of secundly proliferous, halved, pec- 

 tinate pliyllodia. PJiyllodia costate, with diverse sides ; one side flat, 

 areolate, membranous, very entire ; the other pectinato-partite, the 

 laciniae articulated, polysiphonous. Fructification unknown. — Clif- 

 TONiA [Harv.*), in honour of George Clifton, Esq., E. N., the inde- 

 fatigable and successful explorer of the Algse of Western Australia.

Geogr. Distr. Western Australia. 



Descr. Root discoid. Btem coriaceo-cartilaginous, terete, rigid, one or two 

 inches long, branched, the branches ending in phyllodia. Phyllodia 3-3 

 inches long, corab-sliaped, having a cylindrical, densely cellular, opaque costa, 

 falcate, incurved ; the external or convex side of the costa winged with 

 a very narrow, linear lamina, scarcely more than \ line in width, com- 

 posed of oblong, hexagonal cellules, set in horizontal rows ; all of equal 

 length, and 2-3 times as long as broad ; the internal or concave side closely 

 pectinated with a double row of slender, subulate ramelli. These ramelli 

 are four-tubed (of the stnicture of a Polysiphonia), articulated, the arti- 

 culations as long as broad ; they are nearly i inch long, and of the thick- 

 ness of horse-hair. Young phyllodia are given off proliferously from the 

 costa of the older, and are always directed toward the side on which the 

 lamina is developed. The colour is a deep crimson-lake. The substance is 

 membranous, and not very soft, and in drying the plant adheres but imper- 

 fectly to paper. No fructification has, as yet, been observed.
