Very black, exceedingly tender, resembling very fine wool or rough silk. 
Linn. This elegant plant is not more than half an inch high, spreading, 
without any proper stem : branches very slender, interwoven like lace ; 
divisions forked. Dill. 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. 
Griffith. 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. Linnaeus 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 comparing it with the figure, was 
decidedly of opinion that Linnaeus had been mistaken, and that it was 
really 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 rarely elsewhere in the 
Highlands.
