according to Tuiuer, who sent Esper his specimens, although 

 the hitter represents them as having ])een l)ronght from Nootka 

 Sound, B. C, by Cook. They were collected by Menzies accord- 

 ing to Turner. This form is a slender form of the more southern 

 waters, and we have not seen any characteristic specimens of it 

 from our territory. No. 313 of Tilden's American Alga^. from 

 8an Juan Island, Wash., may represent this form, l)ut the 

 specimen is not very complete. Kuetzing's figure of Lophura 

 ffoccosa (1865, ])1. 38, c-e) may be of this form. ])ut it is- transi- 

 tional to f. )i/arr(iraiif}i(i. Fiicus pihilifer of Turner (1819, pi. 

 230) seems to us not to he of this species, but proba})ly a much 

 battered plant of (). Ahiitica. It Avas collected at Nootka Sound, 

 B. C, by Menzies.

A luxuriant form, near f. fi/j)ira, hnt with the lu-anchlets 

 more numerous, longer, slender and recurved so as to give a 

 compact, shaggy appearance to the whole plant. The collecting 

 of the stichidia and cystocarpic branchlets into compact heads 

 with involucre-like outer branchlets characteristic of the species, 

 reaches its extreme in this form as may be seen from the figures 

 on Plate 27. The distichous arrangement of the branchlets is to 

 be seen plainly only at the very ti]i, and even there is often 

 obscure, especially in dried specimens.

This form is sufficiently distinct in ai)pearance to l)e told at a 

 glance, but it is really only a more luxuriant form of tlie typical 

 condition. It seems to be confused at times with Rhodomda 

 Larix, but is distichous in its scheme of branchlets, less coarse 

 and less rigid.
