Plate XXXI. 
Fig. 137. DASYA OCELLATA. 
Colour. A brownish or bright purple. 
Substance. Eigid for so small a plant ; spongy. 
Character of Frond. A delicate little bush ; tufted. Stems simple or nearly so; as thick as 
hogs’ bristles ; opaque ; unjointed ; marked with veiny lines ; densely clothed all 
round with short fringing branchlets which are specially crowded above, making all 
the tips strikingly round and blunt. Branchlets slender, erect, several times forked ; 
jointed throughout. 
Measurement. One or 2 inches high. 
Fructification. Only one kind found in England ; viz. tetraspores^ in long, slender, pointed 
stichidia. 
Habitad. South of England and Ireland. On mud-covered rocks near low-water mark. Bare. 
Fig. 138. CHYLOCLADIA REFLEXA. 
Colour. Purple or dull red. 
Substance. Soft, membranaceous ; not distinctly gelatinous. 
Character of Frond. Small; creeping; oddly bent and branched. Lower branches cylindrical, 
slender, arched, tubular ; attaching themselves to the rock, by tiny branchlets, 
tipped with discs. Secondary branches springing from the arched ones ; very irre- 
gularly placed (sometimes three from one point), tapering at both ends ; contracted 
at intervals as if drawn in ; the joints so formed about once and a half as long as 
broad ; sometimes bearing a few scattered, curved branchlets. 
Measurement. Two or 3 inches high. 
Fructification. Of two kinds. 1. Clustered spores in globose, unstalked {sessile) capsules; 
external : 2. Tetraspores immersed in the smaller branches. 
Habitat. South and west coasts of England ; Ireland, generally. On rocks near low-water mark. 
Now Lomentaria reflexa. Dr. Harvey considers this a variety of G. Kaliformis. 
Fig. 139. BOSTRYCHIA SCORPIOIDES. 
Colour. Dull purple, becoming blackish in drying. 
Substance. Elastic ; but tender. 
Character of Frond. Entangled tufts of slender threads {filaments)., whose tips are more or less 
tightly curled in (like those of a young fern) ; very much branched. Branches very 
wide-spread ; wavy ; furnished with a second or third set, equally spreading ; the 
uppermost with their tips turned in {involute). The whole frond set, at intervals, 
with short, many-tirnes-divided branchlets ; almost horizontally spread. 
Measurement. Four or 5 inches high. 
Fructification. Only one kind observed in England; viz. Tetraspores in lanceolate ; 
external ; borne either on the sides or ends of the branches. Very rarely found. 
Habitat. Certain stations only on our coasts. Muddy sea-shores, near high-water mark ; at 
the estuaries of rivers ; in salt-water marshes and ditches, adhering to the roots of 
flowering plants ; said also to grow on submarine rocks. Very local ; therefore rare.
