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 A/arza which did not seem to agree with any of 
the described species. Nospecimens of the Pacific coast A/a- 
vias were at hand for comparison andthe 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 algz was submitted to Dr. Kjellman who 
pronounced it a new species, related to his A. frelonga and 
A. angusta. 
Alaria curtipes nov. sp. (Plate X XXIII.) 
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 seriately 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. prelonga * Kjellm., and A. an- 
gusta ¢ Kjellm. but according to Dr. Kjellman’s comparison 
** Differs from A. pre/onga in its broader midrib and its shorter
