BRITISH HEPATIC JS. 69 



The fertile state •was unkiiowii to Hooher, although, plants with immature calyces 

 -were sent to him from Ambleside, 1813, G. Lyell I The late W. Wilson, Esq., found 

 it in fruit at Wybenbury Bog, Cheshire, July 1863 ! 



Obs. — Sir W. Hooher, who first published J. anomala and /. Taylori as distinct 

 species, states that the principal difference between them "consists in the ovate 

 and acute leaves of the former, •which are wholly wanting in the latter : other marks, 

 although much less to be depended upon, may be found in the densely crowded 

 patches in which I have always seen J. Taylori grow, so that the individuals are 

 forced into a nearly erect position, and in the colour, which in all the specimens which 

 have fallen under my observation, has been far deeper, and generally with a purplish 

 tinge throughout." 0. Lyell, Esq., in a letter dated Ambleside, July 1813, also states : — 

 "Here and everywhere else it [/. anomala\ retains the characters assigned to it, 

 and no one finds any difficulty in distinguishing it from J. Taylori. I think the 

 leaves are more thin and membranous, and that the cellules are larger when com- 

 pared with the size of the leaf." It will be better, however, to examine the forms 

 in detail, 



Sub-Sp. Tayloui. 

 Pl. IX. Fig, 30. 



Stems (f. 30, 1) densely cEespitose, ascending or erect, flexuose, 

 stout, herbaceous, brownish at the base, green or purple near the 

 summit, tomentose on the under side. 



Rootlets proceeding from the* bases of the leaves and amphi- 

 gastria throughout the length of the stem, long, capillary, trans- 

 lucent or of a flaxen colour ; sometimes, as mentioned by Lyell, 

 " termined by a minute bulb or vesicle." 



Shoots (f. 30, 1, 2) 2" to 4" or more in length, by yo' i^ diameter, 

 gradually increasing in size towards the apex, simple, or innovant 

 from the ventral aspect, or the axils of the iavolucral bracts 

 (f. 30, 6). 



Leaves (f. 30, 2, 3) bifaviously imbricated, alternate, orbiculate 

 to.obovate, -^g" to -y^" in diameter, horizontally patent, rarely secund, 

 the base obliquely amplexicaul, saccate, shortly decurrent, upper 

 portion convex ; margin entire, sub-undulate, apex slightly recurved. 

 Upper leaves crowded together so as to form a rosulate tuft. 



Amphigastria (f. 30, 5) subulate, mostly entire, from the dense 

 rootlets distinguishable only near the summit of the shoots. 



Texture thick, sub-carnose, when dry cartilaginous, repand. 



Colour ferruginous, of a deeper purplish-brown near the summit, 

 rarely green ; lower leaves dirty-brown. 



Mr. Lyell observes that " this species has an agreeable odour, 

 resembling that arising from the flowers of the heath." 



Areolation grossly reticulate, dotted ; from the large size of 

 the trigones, " the cells present a curiously-punctated appearance, 

 observable even to the naked eye " (f. 30, 4, dextral figure).
