on the other hand, they are lateral, when they carry antheridia, some-

form only several branches ; the longest branches consist only of 4, or 
at the most of 5, cylindrical cells, which are hardly twice as long as 
e terminal cells bear hairs abundantly; they are proportion 
coiled. The inferior ramuli serve as shoots of prolification in 
persisting plants. The formation of gelatinous substance 1s not 80
