Fig. 187. KHODYMENIA CILIATA. 



Colour. A deep, fall, more or less bright red; becoming darker in drying. 

 Substance. Thick; firm; elastic; quite crisp when fresh. 



Character of Frond. A flat, ribless, leafy expansion; rising from a very short stalk; 

 more or less broadly lanceolate, or once forked. Margins toothed; or fringed 

 with small, hair-like frondlets, some of w^hich expand into leafy, lanceolate, or 

 once-forked formations like the first; while in others, both on the margin and 

 surface, the capsular fruit is formed. Root fibrous. Fruiting in winter. 



Measurement. From 2 to 8 inches long; width of leaves varying from i to IJ inches! 



Fructification. Of two kinds. 1. A mass of spores in globose capsules, formed in 

 the hair-like frondlets. 2. Tetraspores forming cloud-like patches; dispersed 

 over the surface. 



Habitat. Our shores generally, except the extreme north-east. At Bridlington, but 

 not at Filey. On rocks, &c. near low-water mark, and beyond. Frequent. 



Now GciRihlepharis ciliata. The tips of the hair-like frondlets in which the 

 capsules form are turned aside by the swelling, and project sideways, like the 

 bill of a bird. (See figure.) 



Fig. 188. KHODYMENIA JUBATA. 



Colour. A dull purplish, or pinkish-red. 

 Substance. Thick; soft; elastic; limp. 



Character of Frond. A flat, ribless, leafy expansion; rising from a cylindrical stem; 

 narrow-lanceolate; tapering to the base; branched with leafy formations of the 

 same character; or sometimes with thread-shaped, fibre-like tendrils which 

 spring both from the surface and margins; fringed (like JR. ciliata) with lesser 

 hair-like frondlets, in which the fruit of both kinds is produced. Root fibrous. 

 Fruiting in summer. 



Measurement. From 1 to 8 inches long. Width varying almost incredibly. 



Fructification, Of two kinds. 1. A mass of spores in hemi- spherical capsules, seated 

 {sessile) on the fringing frondlets. 2. Tetraspores immersed in the same. 



Habitat. South and west coasts. On the bottoms of tide-pools between tide-marks; 

 chiefly near low-water mark or among the roots of L. digitata. Frequent. 



So various in width and size that it is very difficult to describe. Sometimes 

 "filiform and entangled," and resembling Gigartina acicularis,
