THE HALF-TIDE POOL. 57 



Chylocladia Paettjla. — A small species, much 

 resembling Chylocladia Kalyformis, and may be recog- 

 nized by its growing parasitical on other plants ; also 

 from the shape of its fruit, which is ovate, not spheri- 

 cal. Colour a pinky-red. Height from two to three 

 inches. Found in deep rock-pools near low-water mark. 



Chylocladia Ovalis (Oval-leafed Chylocladia). — 

 This is a very pretty specimen, but to Lave it in per- 

 fection, seek it in the months of April and May, 

 on rocks and stones within tide marks. There is a 

 difference in its structure that will help the collector 

 in naming it. The stem is not jointed, but solid ; 

 from two to ten inches high, and edged with oblong 

 leaf-like little branches : some of these appear to be 

 single cells, some are compound and set on little stems, 

 like leaves ; if divided length-wise, these joints are seen 

 to be hollow chambers partitioned off by one or two 

 membranes, and filled with fluid. 



Chylocladia Eeflexa (Arched Chylocladia). — 

 This is rare, and properly belongs to low-water mark ; 

 but as it is the last species we shall name, there is no 

 need of separation. . The collector will bear in mind that 

 if he desires to make his collection perfect, and seeks 

 this Chylocladia, it must be on rocks in the sea at 

 lowest ebb of the tide. It is small, and has a creep- 

 ing habit ; sending out arched zigzag branches with 

 little feet or discs, which adhere to the rock like 

 suckers. This alone will enable us to secure a rare 

 plant, found hitherto only on the north coast of Devon, 

 coast of Normandy, and Channel Islands.
