276 ARCTIC LICHENS. 
superioribus subalternis spathulatis vel sublinearibus ; capitulis mini- 
mis, ad apicem ramorum solitariis paucisve aggregatis. 
D. Drummondii, A. Gray (in Hook. Ic. Pl. tab. 855). 
South-western Australia, Drummond.—Stems 3-5 inches long, weak. 
Capitulum less than a line long before fruiting; the scales of the in- 
volucre not at all complicate nor involving the female flowers.  Ligule, 
— if the slightly explanate upper part of the obliquely truncate ccrolla 
may be so called, shorter than the style, very much shorter than the 
auricles of the ovary. Ovaries of the dise wholly sterile, bearing an 
obscure crown at the apex. The singular achenium becomes fully a 
line and a half in length, very much exceeding the involucre; it is 
more or less hirsute, with hairs which are capitate at the apex; the 
stronger hairs of the auricles are glochidiate. The margins of the wing 
are entire, and involute from the first, but they become thicker as the 
achenium matures; the two incurved ascending linear-oblong auricles 
into which they are extended above, are half as long as the achenium 
itself.—This genus is evidently related to Silphiosperma, Steetz, also from 
West Australia, and especially to his S. perpusillum, which is described 
as differing from S. glandulosum in its few-flowered capitula and wni- 
serial involucre. But it is said to have the involucral scales plicate and 
involving the female flowers; and the achenia plano-compressed, not 
excised at the apex or with anything like the singular auricles of the 
present plant. Both genera should doubtless be referred to the Melam- 
podineæ-Parthenieæ. 
Notice, by the Rev. CHuRcuILL BaBiNGtoN, M.A., of the LICHENS 
collected by Dr, Sutherland, during the Arctic Voyage of Capt. Penny, 
in the “ Lady Franklin.” 
No. 91. Parmelia elegans, a, miniata, Scher. ! n. 338 ; on limestone, 
fine and fertile; accompanied by other lichens in an imperfect state, 
among which are, as it seems, P. pulverulenta or aquila, Ach. (barren), 
and P. (Lecanora) vitellina, Ach.: also the scattered apothecia of 
another Lecanora : likewise another lichen (without any crust) which 1 
have also gathered in the Tyrol, which Dr. Montagne (in list) considers 
a Ferrucaria, “ belle et bonne espèce nouvelle," but which recedes 50 
much in character, that it seems to me rather to belong to Fries’s
