;lly the Lichens of the 

north of California, and of the Rocky Mountains, 

ledgement is here due to the liberality 

the late much-lamented Sir, T\\V. Hooker ; to whose ^ 

open hand I also owe an important collection made 

in connection with the Oregon Boundary Commission by 

Dr. Lyall, and a smaller one, from Palliser's British 

I th American Expedition, by Bourgeau. 

Of our own naturalists, Mr. Charles Wright, who has 

herborized, with an eye open for Lichens, in perhaps 

more countries of the globe than any other botanical 

ler, was the earliest to attempt any special collec- 

:n California, and though much limited (as botan- 

N jrth Pacific Expedition,) in time, suc- 

d making several important additions to what 

:nown. i'endler had before communicated 

ries of Lichens collected by him 

was followc : 



the valuable contributions to our knowledge of the 
Lichen-Flora, as well of the coast as of the interior 
mountains, made, during the Mexican Boundary Sur- 
vey, by Mr. Wright and Dr. C. C. Parry ; for which, as 
for many other, long continued favours, I am indebted 
to Professor Torrey. Alectoria Fremontii is a memori- 
al of the celebrated expedition of Capt. J. C. Fremont. 
Other naturalists who have contributed to the extension 
of our list are. Dr. F. V. Hayden (Miss. & Yellowstone 
Expedition) who collected in some of the eastern Val- 
leys of the Kocky Mountains ; and Mr. E. Hall. To 
the careful observations of the latter, and to those, a 
season more recent, of Dr. Parry, almost the whole of 
our scanty knowledge of the important alpine Flora is 
confined. 

The Coast-Flora, especially of California, is however 
still more interesting than the alpine ; and if we except 
some small collections by Professor Newberry, and, at 
San Diego, by Dr. J. G. Cooper, it remained still almost 
unexplored, when Mr. H. N.Bolander, who had already 
devoted himself to the Mosses of the region, collecting, 
says Mr. Lesquereux (Calif. Mosses, in Trans. Amer. 
Phil. Soc.) ' in less than one year . . as many species 
as all the other collectors together, ' turned, happily, his 
attention to the plants before us. 

The intention of this publication is to shew, at the be- 
ginning of careful exploration, exactly what is known 
of the Lichen-Flora of the west coast, south of Van- 
couver's Island ; and of the great, western system of 
mountains, within the same range of latitude. Of the 
very extensive alpine districts embraced, nothing is in- 
deed ascertained, illustrating their lichenose vegetation, 
except in the interior ranges ; but it is likely that these 
represent, in this regard, those nearer the coast. Though 
the deficiences of the list are almost surprising as the

conceptions of the System, to state briefly 
at apprehension of it. Of late long-occupied 
with a tropical Lichen-Flora, I have found great ad- 
vantage in consulting, and to some extent, have foil, 
the method of, the learned memoirs of Dr. Nylander, 
who has added more to the sum of knowledge of t: 
cal Lichens than any other writer, and whose opinions 
derive indisputable weight from the universality of his 
star • '.ever one thing to follow, in a new 

field, the track of a method already indicated, and an- 
other to accept the .System which lies behind ; nor is 
thing more certain than that the long-continued, 
sufficient investigation of particuki . . implies, 

and ought to imply re-tatements of our general notions. 

pie of the illustrious 
s then my full persuasion that his sy 
interpretation of nitiee of Lichens, taken gen- 

erally, or in all its larger features, is still adequate to 
the phenomena; and that succeeding expositions, far 
from supplanting, have derived already not a little of 
their vitality, or nire to seek it, from the pro- 

fou:. jf the botanist of U] 

But science does no: till. The observations of

uon, which De Notaris, Leighton, Massalongo, ana 
Koerber have so sincerely cultivated ; and a new con- 
tent was added to' the conception of species. These 
groups of individuals derive all their value from their 
ideal centres, from the idea, which they more or less 
imperfectly exhibit ; and every advancing approxima- 
tion to completeness in our apprehension of this idea ia 
most obviously important, and may be expected to be 
felt throughout the System. How far, and in what 
manner, the present writer's studies incline him to ap- 
preciate the sporal phenomena of Lichens, will be seen 
from what follows. (*) 

I conceive then, that while less weight than has been 
often assumed should be given to spore-differences of a 
merely gradal character, or such others as depend only 
upon mensuration, more than has sometimes been al- 
lowed should be yielded to those that seem to be typi- 
cal.J Analysis appears to me to indicate two well-de- 
fined kinds of lichen-spores, complemented in the high- 
est tribe only by a well-defined intermediate one. In 
one of these (typically colourless) the originally simple 
spore, passing through a series of modifications, always 



(*)A11 consideration of the notion of 'species' is embarassed 
by the different and uncertain values which (he word is used to 
express. We must distinguish in order to combine. And so 
short is lite, that a generation may be employed in separating, 
What it shall 'fall to another to bring together again; and yet 
the whole honesc concern of both have been the determination of 
'species.' Large views are only possible as the results of much

from which we must be well aware is inadequate ; such

is unknown to us.

sufficiently significant instances, in which nature ap- 
pears to point in the direction we have taken, must be 
left for another place. Let me however be permitted 
at least to say, that if no lichenist would venture to 
separate generically the two forms of Arthonia cyrtodes, 
of the present writer, (Wright Bich. Cub. n. 245,246) 
the way then is plain ly open for the whole of the argu- 
ment! Thellp*ore-oharacter of Biatora, Naeg. & Hepp 
(Hepp Abbild. Sp. t. 1) is in entire accordance with the 
view here taken of the spore-characters as well of 
Biatora and Bccidea as oiBecanora; but I am unac- 
quainted with any writer who has touched the instan- 
ces alluded to in a really appreciative way beside Dr. 
Th. Fries (Lich. Arct. p. 137, 185, 226,) though except 
in a very few, isolated examples, as Gyalecta and Bhi- 
zocarpon (Gen. p. 91) the reasoning suggested by his 
observations has not as yet appeared to modify his con- 
structions. 

According to these views Barmelia proper, Ach., will 
fall into Theloschisles** Barmelia, and Bhyscia ; and 
Lecanora into Blacodium (DC.) Naeg. &. Hepp, Becan- 
ora, and Binodina. Excluding the biatorine forms of 
Blacodium from the Becideei, the latter will have no 
examples of the polar-bilocular sub-type ; but BTetero- 
thecium, corresponding to Bhyscia and Binodina, will

less types and decolorate conditions ; and vice versa. 
The anomalies of Collemaceous Lichens must be con- 
sidered by themselves, and in another place. And to 
this, which is now offered, for what it shall prove to be 
worth, I venture only to add the expression of my 
earnest conviction, that with all the new light which 
the researches of the last thirty years have thrown upon 
Lichenology, this study has not yet advanced so far as 
safely to neglect the wide views, divinations as we now 
know they often were, of the elder lichenographers : — 
or, in other words, that no structural detail, of whatever 
apparent value, can safely assert itself in defiance of the 
argument from general structure ; or otherwise than as 
elucidated by the subtle mediation of Habit.

not hesitate to arrange with this last its fruticulose exaltation, 
so remarkably exhibited on the west Coast. The only known 
example ol this type, was Lecanora fruliculosa Eversm (Sphcero- 
thallia, Fr. Nees, pro p. ) but this is distinguishable, as a mem- 
ber ot the section Aspicilia, from L. Bolanderi, &c. ; and the

cia are distinguishable, by the contrast of colours, by 
the naked eye, but require a powerful lens for their 
(external) examination. They are much more evi- 
dently gyalectine than G. epulotica, Ach., a lichen 
which I am now inclined to consider as best placed 
by Koerber, together with G. odora, Schser., under 
JLccanor a sect. A <j> : <di /, and are comparable rather 
with the Cuban lichen (Wright Lick. 1. c. 5, p. 414.) 
described by me as Gyale ta asteria (Obs. L:<-h. I. c. t 
5, p. 414.) From this the present differs in its black 
exciple with a constantly pore-like aperture, and 
especially in the interesting point that the spores are 
always simple; thus completing the sporal history of 
the genus. It now appears impossible to doubt, that G. 
asteria is identical with Parmelia (Urceolaria) Valen- 
zuehana.'M.ovt. PI. Cell. Cub. p. 205 ; and the Cuban- 
species must therefore take the name of G. Valenzue** 
liana. Samonia, Stizenb., founded upon this lichen 
(Beilr. z. Flechtensyst. p. 1G8) was probably a syste- 
matic consequence, due to Montague's reference of his 
plant to Urceolaria. But it is even more difficult to 
follow Nylander (Obs. in Pot. Zeit.)\n subsuming such 
structure as this under Lecanora. — One word here of 
respectful homage to the memory of that genial cryp- 
togamist who first illustrated the plant we have been 
considering. If a reverent handling of nature, and
