FURTHER NOTES ON HIERACIA. 169 



and was put aside to await better material and further light. In 

 July, 1888, Mr. J. A. Martindale sent good mature specimens from 

 " Crevices of Rock Wren Gill Slate Quarry, in the upper portion of 

 the sprint, " and from "ledges of limestoue rock at the Force, on 

 the stream between Anna Well and Shap (?)." These specimens 

 were seen by Mr. Baker before I received them ; one he called 

 •■* murorum" and the other at first "anglicum " but this determi- 

 nation he erased, and put a "?" instead. The following month 

 Mr. H. E. Fox sent me some fine fresh plants from "Wet rocks 

 in Ghyll, at the back of Kirk Fell, Ennerdale, at 2000 ft.," since 

 which time I have had the plant in cultivation side by side with 

 ordinary f/. anglicum from the same locality, and find it to retain 

 its distinctive features. In 1890, Mr. Fox again sent it me from 

 " Dollywaggon Pike, Cumberland, at 2750 ft.," and in the autumn 

 of the same year the Kev. E. F. Linton sent further examples with 

 other Hieracia to be reported on for the Botanical Exchange Club. 

 The specimens were again Mr. Fox's, and were labelled, "Dove 

 Crag, 2000-2500 ft., Fairfield, Westmoreland." On these speci- 

 mens Mr. Linton made the following pertinent note : — "This came 

 with some genuine H. anglicum, from which it differs by smoother 

 stems, phyllaries shorter, tips senescent, more glabrescent petioles 

 (? thinner leaf), stalked (as a rule) st.-leaf, a floccose-edged phyllary ; 

 and it is a « stylosa ' form — no perfect ligule." There appears to be 

 no example of this form in Mr. Backhouse's herbarium. It is note- 

 worthy that it is usually, if not always, associated with the ordinary 

 form of H. anglicum, and may possibly be a hybrid, but of this we 

 have as yet no sufficient proof. 



H. cerinthiforme Backh. in litt.* var. Harm, n. var. — Mr. 



* The discovery of this extreme form removes all doubt from my mind as to 

 the propriety of specifically separating H. cerinthoides a . of Backhouse from 

 his forms >3. and y. So long ago as the autumn of 1887 I corresponded with 

 him on the forms of "H. anglicum" when he wrote of his own accord, U I 

 sometimes half suspect that my H. cerinthoides a., from the Clova and Braemar 

 district, is not specifically identical with my II. cerinthoides fi. (which latter is 

 Babington's II. anglicum, and well so named). I think that his anglicum and 

 my H. cerinthoides y. are certainly varieties of the same species; but I feel a 

 little doubtful about the other."' The following month he again wrote on the 

 subject, "I feel no doubt that the II. cerinthoides Q. and y., of my monograph, 

 are forms of one species, which I should now call 'II. anglicum a. and /J.' 

 Whether my 'cerinthoides a.' (of the monograph) is specifically ike same as 

 these, I have some doubt ; nevertheless I think it is safest to regard it as such, 

 and to call it var. cerinthiforme.'' On the authority of the above extracts, 

 I introduced the "var. cerinthiforme Backh. in litt." into the th edition of the 

 London Catalogue, and I trust that I may not be charged with any breach of 

 the rules of botanical nomenclature if I still retain Mr. Backhouse's name as 

 the author of "II. cerinthiforme " when used as a specific rather than varietal 

 name. To retain the form I am here describing under the same specific name 

 as the ordinary forms of II. anglicum Fr. would be to violate common sense, 

 though I am prepared to admit that specimens exist which it may be difficult to 

 alloc e with certainty to either species ; but this remark applies quite as much 

 to forms which appear to be equally referable to either anglicum or iricum, yet 

 no one would question the specific differences of these plants, and in nine cases 

 out of ten there is not the slightest difficulty in separating them. I have 

 endeavoured to give full weight to Backhouse's remarks on pp. 38 and 39 of his 



Monograph; his later letters, however, show how much he was prepared to 

 modify his earlier opinions.
