seldom 1 to 5, medium-sized or rather large, wedge-shaped at the 

 base, afterwards slightly rounded. Phyllanes linear, clothed with 

 whitish, rather curly, eglandular, and straight, unequal, glandular 

 hairs (sometimes very few), and, principally towards the base, 

 with fine floccose down ; outer bluntish, rather senescent, inner 

 glabrescent, acute, hyaline at their borders, or wholly so. Ligules 

 golden yellow, about twice as long as the inner phyllaries, quite 

 glabrous at the tips. Styles livid or blackish. Achenes dark 

 chestnut. Pappus dirty white. 



Exsiccata.— E. S. Marshall, Nos. 3589, and 3610 to 3617, 

 inclusive. 



I name this striking plant after my wife Fanny Isabel {nee 

 Foster), in commemoration of our recent " silver wedding " and 

 in gratitude for her constant, sympathetic companionship on so 

 many botanical excursions, over and above the fact that some of 

 the gatherings on which this species is founded were made by her 

 while I was amusing myself by fly-fishing on Loch Ericht, with 

 indifferent success. 



H. Isabella is frequent by rocky alpine and subalpine streams 

 in the neighbourhood of Dalwhinnie, E. Inverness (Shoolbred & 

 Marshall, July, 1911), extending over the county " march " into 

 Perthshire, at 1800 to 2500 feet. Doubtless it will be found else- 

 where. The stations at present known to me are as follows : — 



V.-c. 88, Mid Perth. — Allt Coire Luidhearnaidh, west of Dalna- 

 spidal, and north of Loch Garry. 



V.-c. 96, East Inverness. — Allt a' Choire Bhathaich ; Allt Beal 

 an Sporain ; streamlets on the west side of Ben Alder, below 

 Coire Chomlain ; and Allt an Lochain Dhuibh, about five miles 

 north of Cluny Castle. All these are somewhat shaded localities, 

 with the exception of the Perthshire one, where alone the 

 bronze-leaved state was obtained. It seems to be equally at 

 home on gneiss and granite. 



I believe that this species should be referred to the subsection 

 Aljpina Nigrescentia; the root-leaves show considerable resem- 

 blance to such members of the group as H. nigrescens Willd., and 

 //. submurorum Lindeb., though they have a peculiar fades of 

 their own : and the presence of a few small marginal stalked 

 glands favours such a conclusion. Like H. hyparticum Almq. 

 (otherwise totally different), it has cuneate-based heads; but 

 there are never so few black-stalked glands on any other British 

 member of the subsection. Its nearest ally appears to be 

 //. callistoplujllum F. J. Hanb., the var. cremnanthes of which 

 (fust published under H. Marshall* F. J. Hanb.) has winged 

 petioles. Their head-clothing is much alike, though the simple 

 hairs are more plentiful in H. callistophyllum, which also I incline 

 to refer to Alpina Xigrescentia, and consider to be closely related 

 to II. MarshalM. Lindeberg at first called H. callistophyllum 

 "H. nigrescens* forma; at squamae obtusiores et magis floccosae."
