the appearance of a shrub putting forth its spring leaflets. In early 
growth these little leafy ramuli are nearly oval in form, but as the plant 
advances in growth the ramuli lengthen, and even occasionally taper at the 
apex, which, in most instances, is obtuse or rounded, the bases being 
always attenuated and sometimes even slightly stalked. Globular capsules 
are produced on each side of these ramuli; tetraspores are immersed 
within them. JL. articulata (Fig. 86), formerly, and until very lately, 
Chylocladia articulata, is one of the most abundant of its tribe, being 
found under the shelter of large over-hanging weeds, on rocks, and in tide 
pools, clinging to the surfaces by means of its fibrous roots, like a beautiful 
crimson fleece. This, however, is the stunted form of the species. This 
plant is taken in perfection during the summer months only, by means of

the dredge; though occasionally it is thrown up from deep water. Such 
specimens are deservedly very much admired. The illustration represents 
a luxuriant form of one of these. They are sometimes above 12in. long, and 
are excessively branched ; the stems and branches throughout being con- 
stricted at regular intervals, composed in fact of chains of elliptical bead- 
like joints, and here and there, from the articulations of the upper branches, 
spring whorls of similarly constricted ramuli, the beaded joints of which 
are much shorter and the tips usually pointing upwards ; the whole plant 
when spread out having generally a beautifully rounded outline. Spores 
are contained in conical capsules; tetraspores in the elliptical joints of the 
ramuli. L. parvula, formerly Chylocladia parvula, then removed by Dr. 
Harvey to the genus Champia, and recently placed by Agardh in the genus
