CLIFTONZA LAMOUROUXII, Hav. 
Gun. Cuar. Frond stipitate, formed of secundly proliferous, halved, pec- 
tinate phyllodia. P/yllodia costate, with diverse sides ; one side flat, 
areolate, membranous, very entire; the other pectinatopartite. Fructi- 
fication wiknown.—Curonta (Harv.*), in honour of George Clifton, 
Esq., R.N., the indefatigable and successful explorer of the Alge of 
Western Australia. 
Frons stipitata, ex phyllodiis secunde proliferis hemiphyllis hine pectinatis evoluta. 
Phyllodia costata, lateribus diversis ; uno latere plano areolato membranaceo 
integerrimo, altero pectinatopartito. Hructus ignotus. 
Curronma Lamourouwii; phyllodia scimitar-shaped, semipinnate, their 
laciniz cultrate, flat, toothed on the lower margin, shorter than the 
breadth of the lamina.

Descr. Root unknown to me. Stem 1-2 inches long, nearly a line in diameter, 
coriaceous, rigid when dry, arched, naked, or more or less fringed on the 
concave side with the remains of pinnules. Phyllodia numerous, springing 
from the convex side of the stem, 2-4 inches long, nearly } inch wide, 
scimitar-shaped, the older ones with a valid costa, the younger with a very 
slender one. ‘The outer or convex side of the phyllodium is winged with a 
semilanceolate, transversely striate, delicately membranous lamina, 2 or 3 
lines in width, composed of oblong, hexagonal cellules, set in horizontal 
rows, all of equal length, and about twice or thrice as long as their diameter. 
The internal or concave side is closely pinnulated with a double row of cul- 
trate lacinia, which are rather shorter than the width of the opposite 
lamina. These dacinia are flat and leaflike, and composed, like the opposing 
lamina, of hexagonal, oblong cellules, regularly disposed in transverse lines ; 
they are nearly straight, and quite entire on the upper margin, curved and 
denticulate on the lower; the form is almost exactly that of a coulter. The
