ALGr^I 



H. C. Hart first drew my attention to this variety, which he 

 discovered many years ago on Slieve League, Co. Donegal. The 

 original specimens were by no means carefully dried, and I referred 

 them at the time to H. anr/licum Fr. var. cerinthiforme Backh. in litt. 

 (of the 8th edition, London Catalogue). Last summer I had the 

 opportunity of visiting this mountain in Mr. Hart's company, and 

 found the plant in profusion and just coming into flower; indeed, it 

 was the Hieracium of the mountain. Though nearer to H. cerinthi- 

 forme than to any other previously named form, it is yet so distinct 

 in many particulars as to fully warrant a fresh varietal name. As 

 the plant reaches maturity the obovate radical leaves almost or 

 quite disappear, whilst from three to five large ovate or obovate, 

 acute, entire or minutely and acutely toothed, sessile and strongly 

 amplexicaul stem-leaves alone remain. The broad and rather 

 obtuse, green, lax, softly hairy and pilose-tipped phyllaries afford a 

 further very distinctive character.

ADDITIONAL NOTES ON THE MABINE ALGiE OF THE 



CLYDE SEA-ABEA. 



By E. A. L. Batteks, B.A., LL.B., F.L.S. 



During the period which has elapsed since the appearance of 

 my «Alg« of the Clyde Sea-area' (Journ. Bot. 1891, 209,229,273), 

 the Committee formed for the investigation of the marine flora of 

 "Western Scotland has been actively employed pursuing its work of 

 exploration. Shore-collecting has been systematically carried on, and 

 through the kindness of Dr. John Murray, who on several occasions in 

 July and August put the steam yacht ■ Medusa ' at the disposal of the 

 Committee, dredging operations have to some extent been under- 

 taken. The work of exploration was commenced by Miss E. 

 Barton in June, and was continued during July, August, and part

The localities 



most carefully worked were the islands of Great and Little Cumbrae 

 by myself and party, and the coast of Ayr between Saltcoats and 

 Fairhe by Mr. Holmes. At short intervals since September till 

 the present time Prof. T. King and, more recently, Mr. F. G. 

 Pearcey have examined various portions of the coast, and sent to 

 me for identification whatever they found. I am, therefore, 

 responsible for the correctness of all the names attached to the 

 species recorded in this list, with the exception of a few plant 

 gathered and identified by Mr. Holmes, as well as for the localities 

 to which no other name is attached. Several local collectors have 

 also sent me their collections for examination; it is therefore hoped 

 that the present paper, with the previous list, completes the 

 enumeration of the algae known to inhabit the Clyde sea-area. As 



a result of the work undertaken by the Committee, the following
