the apex, the young shoot rising with a cylindrical stem, which soon expands 
into a frondlet resembling the primary one, and this in old specimens often 
gives birth to a second or third. Tuéercles or nemathecia very convex, dark 
red, sessile on the tips of the frond, composed of dichotomous, densely 
packed, moniliform filaments, radiating from a centre.—8. is not quite two 
inches high, once or twice proliferous, of a fine rose-red colour, the frond- 
lets often bearing above the middle a broad, elliptical, dark-red, thickened 
spot, composed of ¢etraspores.

“The study of natural history,” remarks Mr. Turner in his 
history of the present species, ‘‘ independantly of the advantages 
so nobly ascribed by Cicero to polite literature in general, that it 
nourishes our youth, delights our age, is an ornament in prospe- 
rity, and a comfort in adversity, may justly boast a still superior 
object, in leading, and, indeed, in foremg man to the admiration 
of the wisdom, and the goodness of his divine Creator, in the 
contemplation of the works of his Almighty hand. In addition 
to this it mixes itself also with the daily occurrences of social life, 
and gratifies the best feelings of our nature, by uniting in the 
bonds of friendship those whose pursuits were already the same ; 
while, by permitting the names of its votaries to be affixed to 
plants, it records their zeal im its service, and touches one of the 
most powerful springs of human action. Among those who emi- 
nently deserve to be thus mentioned, stands forward the name of 
James Brodie, Esq., of Brodie, in Scotland, a man at once zealous 
in the pursuit, and liberal in the patronage of universal science, 
and especially of the Botany of Britian.” Mr. Brodie was par- 
ticularly attached to the study of the Algz, among which he made 
many interesting discoveries, the present among the number, and 
during a long and active life, enjoyed the affectionate respect of 
a large circle of scientific friends; the genus Brodiea is conse- 
crated to his memory. The specimen of Phyllophora Brodiai, 
which I here represent was collected by Mr. Brodie, and given to 
me among many others by Dr. Walker Arnott, the present 
owner of the Brodizean Herbarium.
