These are hut varieties of the plant represented in Plate XXXII. Fig. 146. The one to 
the left with branches wide-spread, and mostly opposite, is / 3 . patens. The other clothed with 
quadrifarious horizontal branchlets, is y. squarrosa. (See under Fig. 146.) 
Fig. 152. DASYA AEBUSCULA. 
Colour. Pale reddish-brown ; sometimes deep red. 
Substance, Soft and tender. 
Character of Frond. A very delicate little bush; tufted. Stems as thick as a fine hog’s 
bristle ; much and irregularly branched ; sometimes forked {dichotomous)^ sometimes 
furnished with wavy, more or less spreading, alternate branches, which are several 
times re-branched, and all densely clothed with slender fringing branchlets. Branch- 
lets short, forked, horizontally set, giving the stems a roundish bottle-brush ap- 
* pearance ; crowded at the tips as in D. ocellata. 
Measurement. From 2 to 4 inches high. 
Fructification. Of two kinds. 1. Clustered spores- in ovate capsules^ which have a long 
cylindrical mouth ; external, on the branchlets. 2. Tetraspores in pointed oblong 
stichidia. 
Habitat. South of England (Plymouthj &c.). Ireland and Scotland. Very fine at Bantry. 
On rocks at the verge of low-water mark. Xot common. 
" A more slender variety, with more regularly forked branching, is obtained by dredging. 
Alike as this pretty little plant and Dasya ocellata are to each other in general look, they may 
easily be distinguished on careful examination. The stems of D. ocellata are usually quite 
simple, and in shape like a peacock’s feather ; or else slightly branched in the upper part ; 
while those of D. arbuscula are profusely branched either in a forked manner, or with alternate 
branches which are more than once re-branched. The fringing branchlets are common to 
both species, but those of D. arbuscula are not above one- sixth of an inch in length. 
Fig. 153. CHYLOCLADIA PAEVULA. 
Colour. A fine but fugitive pinky-red. 
Substance. Soft and somewhat gelatinous. 
Character of Frond. Slender ; tubular ; constricted at intervals into somewhat inflated joints ; 
much branched and entangled. Branches irregular ; alternate, or secund; of various 
lengths ; with or without scattered branchlets, which taper slightly to the base. 
Joint-contractions as long as broad. Boot a mass of fibres. 
Measurement. Two or 3 inches long. 
Fructification. Of two kinds. 1. Masses of spores in conical capsules; external; seated 
{sessile) on the branchlets. 2. Teti^aspores ; imbedded in the same. 
Habitat. South of England. Not uncommon on the shores of Ireland and west of Scotland,
