F o u n d on various parts of the British sea shores. Miss
Biddulph has obligingly communicated it in fruit from South-
ampton, see / g . I ; along with C. verticillata in the same
state, which we subjoin a t/ . 2, as an addition to our t. 1718.
C. spongiosa differs from verticillata in being more of an
olive or greenish hue, and especially in the fine filaments which
clothe its stem and branches being scattered, not whorled, as
well as constantly simple. The capsules are stalked, obovate,
situated on the shorter filaments of the branches, whereas those
of the verticillata, not known to Mr. Dfilwyn, are observed
by Miss Biddulph to proceed from the filaments of the old
stem only, and to be of an elliptic-oblong shape.
