XXX. A NEW SPECIES OF ALARIA. 



DE ALTON SAUNDERS. 



During the summer of 1896 while investigating some physio- 

 logical problems in the Hopkins Sea-side laboratory, the writer 

 collected an Alaria which did not seem to agree with any of 

 the described species. No specimens of the Pacific coast Ala- 

 rias were at hand for comparison and the writer being loath to 

 add further to the synonymy of this variable group laid the 

 plant aside until a favorable opportunity for study should pre- 

 sent itself. Recently a specimen of this plant with several other 

 species of Alaskan algas was submitted to Dr. Kjellman who 

 pronounced it a new species, related to his A. -prcelonga and 

 A. angusta. 



Alaria curtipes nov. sp. (Plate XXXIII.) 



Plant of medium size, one to three or more meters long, dark 

 olive brown, coriaceous ; stipe very short (1-4 cm. long), firm, 

 robust, black, narrowed below, but little flattened above ; rachis 

 short, somewhat compressed, gradually passing into the midrib ; 

 blade linear or narrowly lanceolate, 1-3 dcm. wide, narrowed 

 above ; midrib prominent, 1-2 cm. broad, projecting equally on 

 both surfaces of the blade, quadrangular in cross section ; spor- 

 ophylls ovate, lanceolate or elliptical, obtusely rounded above, 

 2-3 cm. wide, 7-15 cm. long, 16-40 or more borne sedately on 

 a distinct stalk 5-10 mm. long ; fruiting area confined to the 

 lower half of the sporophylls. 



Abundant on exposed rocky points on the central Californian 

 coast, Monterey bay, Carmel bay, and Point Sur. 



A. curtipes is related to A. prcelonga * Kjellm., and A. an- 

 gusta f Kjellm. but according to Dr. Kjellman's comparison 

 " Differs from A. prcelonga in its broader midrib and its shorter
