3. Cliantraiisia liallaudica Kylin. 



H. Kylin (1906) p. 123. 

 Ch.parvula Kylin (1906) p. 124. 



Kylin in 190() described Iwo allied species, Ch. hallandica and Ch. pannila, 

 dilTering from each other by the lihimenLs being a lillle thinner, giving branches 

 off at all sides and consisting of longer cells, further by the sporangia being often 

 stalked and then usually placed two or three together in Ch. hallandica, while 

 Ch. parvida is smaller, 

 has shorter, a little 

 thicker filaments with 

 branches placed in one 

 or two rows and usually 

 sessile sporangia. In se- 

 veral places in the Da- 

 nish waters I have met 

 with C/ja/?/ransz(c agree- 

 ing exactly with these 

 two species, but I have 

 also found specimens 

 which were intermedi- 

 ate in regard to one or 

 more of the characters 

 mentioned. As I have 

 also found sexual or- 

 gans, besides the spor- 

 angia described by Ky- 

 lin, it will be necessary 

 to mention these plants 

 more closely. 



In the plants corre- 

 sponding to Kylin's Ch. 

 hallandica, the basal cell 

 is (7,5— ) 9— 11 (—14)/^ 

 in diameter, thick-wall- 

 ed; it gives oir usually 



3, at the most 4 erect filaments, (4 — )5 6 /t thick and consisting of cells usually 

 3—4 ( — 5) times as long as broad. Hyaline hairs are usually present. The origi- 

 nally terminal hair is often pushed aside by the cell bearing it growing out sym- 

 podially in the same direction as before, and the hair leaves then only a faint 

 mark at the upper end of the cell which has produced it; but in other cases the 

 hair retains it terminal position, and the filament, i. e. the branch, grows out in 

 another direction (fig. 21 E). Transitional cases are also found. The cells contain
