Mr. Griffith is satisfied that the L. lanatus and L. chalybei- 
formis are not distinct, nor have I yet seen any specimens 
which can justify a different opinion.

Very black, exceedingly tender, resembling very fine wool 
or rough silk. Linn, This elegant plant is not more than 2 
inch high, spreading, without any proper stem; branches very 
slender, interwoven like lace; divisions forked. Ditt. Of a 
black fuscous’ colour, but paler towards the extremities. Saucers 
near the centre of the plant of an olive colour; very rarely 
found. They are at first concave with an inflected margin, 
wrinkled when magnified. ‘They scarcely rise above the thread- 
like branches, but at length the margins become reflected and 
the saucer more elevated, assuming the shape of a tubercle, 
about the size of a vetch seed. ‘The plant-has not the polished 
appearance when in fruit. Mr. Grirrrru. From the specimens 
before me it would seem that the plant in its younger state is 
quite black and polished, brown black when older, losing its 
polish, and when very old bleaching to pale brown and even to 
white. Linnzus had given the above figure of Dillenius to his 
variety of the L. islandicus marked y, but Mr. Lightfoot after 
an examination of the original specimen of Dillenius and com- 
ey Se with the figure, was decidedly of opinion that Linné 
been mistaken, and that it was really the L. pubescens. In 
a finely fruited specimen sent by Mr, Brown the saucers are, 
sometimes edged with prickles like projections, probably the 
origin of young branches ; they are brown black on the surface, 
White and pithy within. _Mr. Brown says it always produces 
fructifications on the summit of Lochain in Breadalbane, though 
tarely elsewhere in the Highlands. Tei i ‘tei
