DASYA SARCOCAULON, Zar. 
Gun. Cuan. Frond filiform or compressed, dendroid; stem and branches 
coated with small, polygonal cells (rarely articulated, and many-tubed) ; 
the axis articulate, composed of several radiating cells surrounding 
a central cavity; ramelli articulated, one-tubed. Fruetification: 1, 
ovate or urceolate ceramidia; 2, lanceolate stichidia, attached to the 
ramelli, and containing triangularly-parted tetraspores in transverse 
rows.—Dasya (dy.), from dacus, hairy. 
Frons filiformis v. compressa, dendroidea. Caulis ramique majores strato cel- 
lularum corticati (raro pellucide articulati), ramellis monosiphontis obsessi ; 
axis articulatus, ex cellulis pluribus radiantibus tubum centralem cingentibus 
formatus. Fruct.: 1, ceramidia ovata v. urceolata ; 2, stichidia lanceolata, 
ex ramellis enata, tetrasporas transversim ordinatas foventia. 
Dasya sarcocaulon ; frond rosy, dendroid, forked or subsimple, very thick 
and succulent, alternately decompound; stem and branches thickly 
corticated with minute cellules, glabrous, beset with short brush-like 
ramuli; ramuli subulate or filiform, spreading to all sides, clothed 
with short, very slender, taper-pointed, dichotomous ramelli; articu- 
lations of the ramelli about thrice as long as broad.

Geocr. Distr. Western Australia. 
Descr. Root unknown. Frond at least 4-5 inches long (but probably much 
more), 1-2 lines in diameter, opaque and thickly coated with small cells 
throughout, tapering to the ends of the branches, irregularly divided, but 
(comparatively) not much branched. Stem and branches quite glabrous, 
bare of ramelli; the branches spreading to all sides, sometimes bearing a 
second series of similar branches, which, as well as the primary, are 
sprinkled with short ramuli. These ramuli are patent, either awl-shaped or 
thread-shaped, opaque, and beset on all sides with very slender, minute, 
dichotomous ramelli. Ramelli scarcely a line, often not half a line in length, 
articulated; their articulations thrice as long as broad. ructification un-
