DR. Е. BORGESEN ON FUCUS SPIRALIS, LINNÉ. 109 
Which are usually more or less swollen and roundish-oval, and oecur terminally 
either two on each branch, or cordate if the bipartition is not complete. On 
observing а well-pressed herbarium specimen of a typical Fucus spiralis 
(e. g., Areschoug’s Exsicc. No. 54), all the receptacles will be seen to occur 
along the periphery of the plant, while in var. platycarpa they are situated 
along the main branches, beginning from somewhere near their base. Itis 
a pity that Kjellman, who in N. I. refers this species to Fucus spiralis, does 
not give any reason for having in * Handbok ° given 16 the name F. Areschougit. 
In his description of В. borealis, Kjellman just writes in a footnote :— If the 
name Fucus spiralis, L., agrees with this species, then it must most properly 
be applied to the northern form. 
“With regard to forma папа (fig. 96%), the latter is only a small dwarf 
form of f. typica. I have reported Fucus limitaneus, Mont., as synonymous 
with this form on the strength of some specimens gathered in the Canary 
Islands by the late Mr. O. Gelert.... Further, Prof. Sauvageau kindly sent 
Fucus spiralis, L., f. папа. 1:1. (Н. Westergaard, del.) 
me specimens of this form from Cap du Figuier in the Bay of Biscay ; he 
calls them Fucus platycarpus, var. limitaneus у and with reference to them he 
writes, l. с. pp. 171-2 :— En 1896, j'en ai récolté sur un bloc situé en avant 
du Casino, de petits, gréles et bien fructifiés, en touffes éparses, de 2 à 3 
centimétres de longueur, et j'étonnerai probablement les algologues qui ont 
exploré seulement les régions plus septentrionales, en disant que j'aie pu 
faire rentrer dans une boite d'allumettes ma récolte, qui se composait d'une 
dizaine d'exemplaires bien entiers” The Færüese specimens from exposed 
localities are often as small.
