1857-] SALTER DEVONIAN PLANT-REMAINS. 75 



A fossil fern found in Orkney and described in Hugh Miller's 

 work (p. 25) has not occurred among the specimens under our 

 notice. 



Lycopodites Milleri, sp. nov. PI. V. figs. 8a, 86. 



L. ramis fiagelliformibus, 2 pedes et ultra longis; ramulis remotis, 

 foliis secundis 2-3 lineas longis, lanceolatis [obtusisV], 



This fine specimen is worthy of a name on account of the rarity 

 of such remains in rocks of this age ; but not much can be said as 

 to its structure. The stem (only a fragment 2 feet long is pre- 

 served) is flexuous, about fths of an inch thick, and was probably of 

 prostrate growth as indicated by the secund arrangements of the 

 foliage, and the length and slenderness of the stem itself. In this 

 length of 2 feet are only two short branches, about an inch long, 

 and about 7 inches apart, and set on at a very oblique angle, as often 

 seen in recent Club-mosses. The foliage is much larger than in the 

 Lepidodendron next described. The leaves are very indistinct, but 

 are about -^rd of an inch long, lanceolate (obtuse ?), and much curved 

 upwards to one side (the upper side probably). There is some in- 

 dication of their being set on in spiral lines, instead of quincuncially. 



Locality. Near Thurso. (Mr. John Miller's collection.)

Stems about a foot long, or even longer, and nearly \ an inch 

 broad, tapering but very little from end to end ; the branches short, 

 set on at an acute angle, and blunt at their terminations. Leaves in 

 7 to 10 rows, very short, not a line long, and scale-like, of an ovate, 

 acuminated form, and rather spreading than closely imbricate. Their 

 acuminate tips are about as long as their broader bases (fig. 9 c). 



Our specimens do not agree exactly with that figured by Unger, 

 having the scales or leaves rather longer. But his figure appears to 

 show only the cicatrices, not the leaves themselves ; and the size, 

 diameter of the branches, and close small leaf-scars in both agree, 

 and are different from any species that I have seen figured from the 

 Coal-formation. 



Loc. From Stromness, Mr. Peach ; Thurso, Mr. John Miller. 

 Abundant. 



The late Mr. Hugh Miller figured* a fine and much-branched 

 specimen of this species. We have others, in which the main stem 

 (a little flexuous) gives off short and narrower branchlets, which are 

 again branched, as in his figure. The tips of the shoots often 

 scarcely show the scales.
