the apex, the young shoot rising with a cylindrical stem, which soon expands
into a fronillet resembling the primary one, and this in old specimens often
gives birth to a second or tliii’d. Tubercles or nemathecia very convex, dark
red, sessile on the tips of the frond, composed of dichotomous, densely
packed, moniliforin filaments, radiating from a centre.— is not quite two
inches high, once or twice proliferous, of a fine rose-red colom', the froud-
lets often healing above the middle a broad, elliptical, dark-red, thickened
spot, composed of tetraspores.
“ 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 prosperity,
and a comfort in adversity, may justly boast a still superior
object, in leading, and, indeed, in forcing 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 in its service, and touches one of the
most powerful springs of human action. Among those who eminently
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 particularly
attached to the study of the Algæ, 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 Brodioea is consecrated
to his memory. The specimen of Bhjllophora Brodiæi,
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 Brodiæan Herbarium.
