432 ALG4E OF TASMANIA. 
The Cape of Good Hope species which I have sent to 
several of my friends either as * Rytiphlea? n. sp.," or “Nov. 
Gen.” may be thus characterised :— 
Pollexfenia Jaciniata, Harv.; fronde flabelliformi basi cu- 
neatá, in segmentis lineari-cuneatis, laciniatis, palmato- 
multifidis, vel subdichotomis, erecto-patentibus, profunde 
fissa; margine lacero-dentato ; sinubus obtusis; apicibus 
laceratis ; keramidiis sessilibus. 
At Muysenberg, False Bay, C. B. S., growing with Tham- 
nophora corallorhiza near low water mark, W. H. Harvey. 
Fronds tufted, 6-7 inches high, narrow at the base, becoming 
gradually wider till they are half an inch broad; then spread- 
ing with a fanshaped or broadly ovate outline, and divided in 
a partly dichotomous, partly pinnate manner, the segments 
generally half an inch wide, nearly linear, erecto-patent, and 
again dividing in the same irregular manner. The axils every 
where rounded, but not very broad. The apices generally 
jagged; and the margin either toothed, lacero-dentate or 
almost ciliate at times. Keramidia sessile, generally neat the 
margin, few on each frond, depresso-ovate or mamilleform, 
thick and fleshy. Stichidia unknown. Colour fine purple- 
ted, with iridescent tints when fresh, becoming darker and 
duller on drying. It adheres to paper. ; 
4. Dasya naccarioides, Harv.; caule crasso, longissimo, 1 
diviso, ramisque nudo, cartilagineo ; ramis alternis, p10- 
natis vel sub-bipinnatis ; pinnis claveformibus, filis verti- 
cillatis, dichotomis, articulatis, minimis, densissime vestis 
filorum axillis patentibus, articulis inferioribus subduplo, 
superioribus quadruplo diametro longioribus; stich 
oblongis, obtusis, spherosporas biseriales includentibus. — 
George Town, V. D. L., R. Gunn, Esq., n. 1287.—Stem 12 
inches long or more, 1-2 lines thick, cartilaginous, shrinking 
in drying, quite naked, undivided, but furnished from base tò — ; 
apex at distances varying from 4 inch to an inch, with 
spreading, alternate, undivided branches similar to the Sem» — 
but only one fourth of its diameter. These produce a -— 
series of undivided branchlets or pinnze, which are also about > 
3 the diameter of the branches ; and in luxuriant !
