1914] Setchell: The Scinaia Assemblage 117 



A slender species, known only from two specimens in Ilerl). Far- 

 low, collected at St. Lucie, Florida, by Mrs. G. A. Hall. G. IlalUae 

 approaches G. Okamurai but is thinner-walled, somewhat taller, with 

 less number of dichotomies, and is widely separated geographically. 

 The other species of the genus are either found in the Pacific Ocean 

 or in the Indian Ocean and the occurrence of an undoubted species of 

 this genus in the North Atlantic suggests the extreme possibility of 

 there being other members of the genus Gloiophloea on the American 

 or European coasts.

 Scinaia furcdlata Barton, Journ. of Botany, vol. 31, p. 144, 1893(?). 



Plant 7-9 cm. high, 7-11 times dichotomous, cylindrical, continuous, 

 1-3 mm. broad (dried), dark red, fleshy cartilaginous; axis invisible; 

 cystocarps irregularly aggregated ; — axial strand slender, loose ; adult 

 cortex 110-150jLt thick, the outer cortex 60-85/i, thick, of anticlinal 

 moniliform rows of colored cells with 1-2 sets of utricles at different 

 heights, the inner cortex 50-65/a thick, of loosely interwoven hyphae; 

 dioecious ; antheridia covering almost the entire surface of the anther- 

 idial plant, single at the tips of slender elongated cells, oblong; cysto- 

 carps broadly obpyriform, 65-130/a (R) by 115-150/x (T), with a 

 filamentous periderm of 5-9 layers of filaments. 



Gloiophloea capensis is founded on an antheridia! plant collected 

 at Port Alfred, Cape Colony, by J. Burtt Davy in 1908. Another 

 antheridial plant collected in the Cape Colony region by Poeppig 

 exists in Herb. Farlow and has been examined. Finally I have found 

 a cystocarpic plant collected at ''The Koaahc," South Africa, by Dr. 

 H. Becker among the specimens of Scinaia kindly loaned from the 

 Herbarium of the Konigliche Biologische Anstalt 7a\ Helgoland 

 through the kindness of Dr. Paul Kuckuck. This account then has 

 b(»en drawn up after a study of tliese three specimens. 



Gloiophloea capensis is a true Gloiophloea in the light of what has 

 been said here of the genus and is dioecious. From Gloiophloea 

 confusa, the other dioecious species known to me, it is to be dis- 

 tinguished by its small number of dichotomies and its decidedly 

 thicker outer cortex. The cortex is comparatively thin in the cysto- 

 carpic plant and noticeably thicker in the antheridial plant. It is 

 probable that the various references to the occurcuce of Scinaia 

 fiiycdhtia on the South African coasts refer to this species wholly or 

 ill part.
