CHYLOCLADIA REFLEXA, ZLenorm. 
Grn. Cuar. Frond tubular, constricted at regular intervals, and divided 
by internal diaphragms into joints, filled with watery juice, and 
traversed by a few longitudinal filaments; periphery composed of 
small, polygonal cellules. ructification of two kinds, on distinct 
individuals ; 1, spherical, ovate, or conical capsules (ceramidia) con- 
taining a tuft of wedge-shaped seeds, on a central placenta. 2, tri- 
partite ¢e¢raspores, immersed in the smaller branches near their apices. 
Cuyociapia (Grev.)—from xvdds, juice, and Kdados, a branch. 
Cuytoctapia refleva; frond membranaceous, purple; lower branches 
cylindrical, slender, arched, attaching themselves by short ramuli 
tipped with discs; secondary branches simple, mostly secund, moni- 
7 hform, spindle-shaped ; ramuli few, scattered, patent or recurved.

Grocer. Distr. Coast of Normandy. North coast of Devon. 
Descr. Root an expanded, fleshy disc. Frond from two to three inches high, 
half a line to a line in diameter, branching from the base in an irregular 
manner ; the lower or main branches cylindrical, scarcely constricted, slender, 
arched, zigzag, forming successive ares in one direction, and furnished at 
the concave side of the are with short holdfasts, tipped with dises, by 
means of which the frond attaches itself to neighbouring objects, in a 
creeping manner; the upper or secondary branches springing from the 
arched ones, either two or three from one point or solitary, generally uni- 
lateral, simple, spindle-shaped, moniliform, constricted at regular intervals 
into joints about once and a half as long as broad, the upper joints gradually 
shorter to the tips. Ramuli few, short and mostly secund, patent or re- 
curved, sometimes but rarely binate. Capsules spherical, with a pellucid 
border, containing a very dense mass of angular seeds. Tetvaspores abun- 
dantly produced in the tips of the branches and ramuli. Colour a dull 
purple. Substance membranaceous, adhering to paper.
