No. 2. S. Montagnei. Bailey. Leaves linear, somewhat serrated, less branch¬ 
ed than the preceding; air vessels spherical, stalked. 
Found floating occasionally at Red Hook and Hurlgate; is abundant in the Sound near our harbor, 
whence it probably drifts with the tide into our waters. 
Genus FUCUS. Linnaeus. 
Root scutate ; plant linear, flat, or compressed, cylindrical at base, dichotomous ; 
air vessels, when present, simple; receptacles generally at the apices, traversed by a 
net-work of jointed fibres, pierced by numerous pores. 
No. 8. F. vesiculosus , L. Flat, thick, coriaceous, linear, dichotomous, midrib- 
bed ; air vessels when present mostly in pairs ; receptacles elliptical at the apices.— 
Hook. 
Very abundant on most rocks in the harbor; in unfavorable localities ten inches ; frequently two feet, 
and at Hurlgate and Yellow Hook four feet long. 
No. 9. F. vesiculosus , id. Yar. A, 
A variety occasionally found floating in the harbor; air vessels entirely absent. It is very abundant on 
sandy shores in the Sound. The lens will show two rows of circular holes on either side of the midrih; these 
holes are inhabited by a Zoophyte, who, like the hermit crab, exhibit no scruples in occupying the house 
of a neighbor. Unlike the hermit crab, however, this insect allows his neighbor to live in a miserable, half- 
famished condition ; the plant in this state is always dwarf, and we may account for the absence of air ves¬ 
sels, by supposing this insect, with his tentacula active, to be of less specific gravity than water. 
No. 10. F. vesiculosus , id. Yar. B. 
This variety is common in all parts of the Bay ; it inhabits the rocks at and above high water mark ; it 
will serve as an apt lesson to those wearied of life. This plant, from the position of its habitat, is frequently 
for several consecutive days above the reach of the tide, and moistened only by the spray. It lives seemingly 
in hope of a spring tide, or a favorable change in domestic affairs; the long hoped for billows generally bring 
floating sticks, chips, and other matter, to fret and tear its sides, so that it is sometimes difficult to recognize 
it as belonging to the family Fucaceae. 
No. 11. F. nodosus , L. Coriaceous, without midrib, distichous, occasionally 
sub-dichotomous, linear, attenuated at base ; air vessels oblong; single receptacles 
lateral. 
Common on most rocks, and particularly abundant at Staten Island, Owls Head, Yellow Hook, and 
Hurlgate; perennial, fruiting in winter and spring; frequently five feet long; dark shining olive; not so 
abundant as F. vesiculosus, though the same rock is often the habitat of both species. 
No. 12. F. nodosus , id. Yar. A. 
This dwarf variety is abundant in the Sound ; occasionally found floating at Red Hook and at Hurlgate 
Sometimes the olive color natural to this plant, is changed to a dull yellow, probably the effect of bleaching 
No. 13. F. Mackaii , Turn. Cylindrical or sub-compressed, slender, much 
branched ; branches dichotomous; air vessels elliptical, solitary; receptacles lateral, 
lanceolate, ovate or forked, pendulous, scattered near the base of the branches._ 
Grev. 
Found by a friend at Hurlgate, on one occasion only. I have not had the good fortune to find it, though 
I have repeatedly visited every visible rock at Hurlgate.
