164 DR. HARVEY ON A COLLECTION OF ALGE 
Stem 2-3 inches long. Fronds numerous, closely inserted, 
2-3 feet long, 1-14 line in diameter, in outline of branches lan- 
ceolate. Lateral branches 4-6 inches long, in pairs or irregularly 
scattered, patent, sub-bipinnate; the lower pinnules leaf-bearing, 
the upper vesiculiferous, each ramulus having a vesicle below its 
apex. Vesicles 1-1} line long, like the pods of some Lepidium. 
No fruit on our specimens, which quite agree with those distri- 
buted by Dr. Ruprecht, from the Sea of Ochotzk. Though nearly 
allied to C. geminatum, J. Ag., it appears to be distinct.
