248 BOTANY OF THE VOYAGE OF H.M.S. HERALD. 
authentic specimen. The present species is nearly allied to S. damcscornis, and may even prove to "be a 
variety of it. The upper surface is of a rather bright ochroleucous hue, rugose and scrobiculated (but less 
so than in the allied species, S.faveolata, etc.) ; lacinice several times forked, comiculated at the apices, rather 
broad towards the base, i. e. the centre of the thallus. The under side is naked or sparingly clothed with 
brown pubescence ; cyphclla; urceolated, tumid, externally yellowish, scarcely paler -within ; apothecia prin- 
cipally marginal, rather small, rufous, their margin at length erect, somewhat waved and crenulatcd.

of BouquctCj Vcraguas ; fertile. 
The present plant is also found in other parts of New Granada and in Peru. "Whether it is distinct 
or not from S. dmecta, Ach., I am unable to say, being unacquainted with his var. corrosa {S. dissecta, 
Delise). 
1204. Sticta Seemannii, Chnxcli. Bab. MSS. ; fronde stipitata flabellata laciniata glanca passim 
nifescente^ laciniis elongatis linearibus subcanalicidatis repetitim dichotomis superne tantum sub- 
costatis, marginibus undulatis intcgcrriniis, subtus omnino nuda fuscescente, cyphcllis minutissimis 
profunde immersis buUatis albis, stipite brevi lignoso crassissimo, apotlieciis marginalibus elevatis 
liberis, disco nigricantc margine tcnui snbflexuoso pallido femigineo-fusco. Volcano of Chiriqni, 
Veraguas. 
A handsome Lichen, which I am not able to refer safely to any described species, although it is just 
possible that it may be a form of S.JlUcina, Ach. The lobes of S.Jilicina are much less elongated (being 
Binuated and scarcely dichotomous) , and are erose and crenate at the extremities ; the under side is of a 
bright ferruginous colour, and the costae extend to the extremities of the lobes ; the apothecia ia fine are 
red. S. htijrons, A. Eich.! {S. Menziesii, Hook, fil.! et Tayl.!) is likewise allied to S. Seemannii ; it has, 
however, very broad and Httle divided fronds ; the apothecia are scattered over the surface, and the cyphellse 
are very large and not bullated; it is pubescent beneath. S. marginifera, Mont.!, is barren, and may pos- 
sibly be the present species : the specimen in the Hookerian herbarium is small and unsatisfactory. Dr. 
Seemann's specimen spreads Hke a fan, from a thick stipes about an inch long ; the circumscription of the 
frond is nearly semicircular, the radius being from four to five inches, with an irregularly wedge-shaped 
base. The ramification is not unlike that of Sticta damcBCornis or S. macrophylla^ but it is more repeatedly 
forked. The upper surface is concave, glaucous green, tinged with red towards the base ; the under side 
is black near the stipes, passing off into a pale ferrugiuous brown, perfectly naked ; the apothecia are all 
marginal, almost stipitate, and the disc black.
