to paper. Tetraspores sometimes cruciate, but generally triangularly divi 
immersed in the ramuli, near theiy apices, and generally disposed in longi- 
tudinal series on the outer edge of the branchlet. Fuvelle sessile on the 
outer margin of the ramuli, subglobose, or irregularly shaped, occasionally 
lobed, containing very numerous angular spores, and clasped by two or 
three short, involucral ramuli.

We are informed by Mr. Turner, in his ‘ Historia Fucorum’, 
that a specimen of this beautiful plant, of British origin, but 
uncertain locality, had long been preserved in the Banksian 
Herbarium under the MS. name Fucus glandulosus, but remained 
unpublished until Mrs. Griffiths, in September, 1803, fortunately 
discovered it again upon the Devonshire coast, and enabled him 
to figure and describe it for the first time. Since that period it 
has been found, as far as I am aware, in but two other British 
stations, and in neither of them of such large size as in Torbay. 
''o Miss Warren of Flushing I am indebted for a great number 
of specimens, and to Mrs. Griffiths for the fine specimen here 
represented, and others in both kinds of fruit. I believe no one 
in Britain but Mrs. Griffiths has yet found Favelle. On the 
continent, Microcladia glandulosa is decidedly rare, though found 
along the shores of France and Spain. Professor J. Agardh 
omits it im his ‘Algze Maris Mediterranei’, but Kiitzing has 
received it from Marseilles. Bishop Agardh mentions specimens 
from Kamtschatka, which, though somewhat different from the 
European plant, he considers to belong to the same species. 
This, if correct, is an interesting fact im the distribution of so 
rare a plant. 
As a genus, MWicrocladia is very closely indeed allied to Cera- 
mium, with which it agrees in habit, and merely differs in some 
minor points of structure. Some specimens of Cer. rubrum nearly 
resemble it, but the absence of external jomts in the Wicrocladia, 
is a character sufficiently obvious to distinguish it from the Cera- 
mium.  Microcladia glandulosa is often found tangled with other 
Alge, upon which it grows; and sometimes, as Mrs. Griffiths 
observes, creeps over them in the manner of a Cuscuta, throwing 
out root-like fibres along the branches. These adhere so strongly, 
that it is impossible to disengage them without laceration.
