 lieic/i. Ic. Fl. Germ, et Helv. Vol. VI. Mah. Tab. CLXXVIII. Fig. 4857. 



Stem erect, very stout. Leaves 5- to 7-lobed, with short 

 velvety pubescence. Peduncles several together, shorter than the 

 leaves from which they spring. Epicalyx 3-lobed, longer than the 

 sepals. Projecting point of the torus conical, ribbed. 



On maritime rocks, especially such as are insulated. On the South 

 and West coast, from Hants to the Isle of Man, and possibly native 

 on Ailsa Craig at the mouth of the Eirth of Clyde. Often culti- 

 vated ; and as it becomes readily naturalized, it is to be found in 

 various other places, as on the Bass Rock in Haddingtonshire, and 

 on other islands in the Firth of Forth. 



England, Scotland ?, Ireland. Biennial. Late Summer and 



Autumn. 



Stem woody, 2 to 8 feet high, and in large examples often 1 

 inch in diameter. Leaves stalked, sometimes attaining a diameter 

 of 8 or 9 inches, roundish, cordate at the base, the large ones 

 7- and the upper ones 5-lobed ; lobes deltoid, crenate or crenate- 

 dentate. Flowers 1^ inch across, pale purple with broad dark veins 

 confluent at the base, arranged in racemes or raceme-like panicles at 

 tlie exti'emity of the stem and branches. Epicalyx very large, with 

 o broadly-ovate obtuse lobes united nearly to the middle. Sepals 

 deltoid. Petals wedgeshaped-obovate, truncate and emarginate at 

 the apex. Styles about equal to the stamens in length. Carpels 

 ])ale olive, flat on the sides, with radiating wrinkles ; the sides 

 not rounded oflp, but forming a sharp angle with the back, which is 

 reticulated with elevated lines, glabrous. Fruiting calyx closely 

 connivent. Plant rather dull green, covered with a thin soft coat 

 of stellate hairs. 



The enormously large epicalyx with 3 ovate obtuse lobes 

 sufficiently distinguishes this from the other British Malvace;e, 

 from all of which it also differs in its mode of growth, which 

 resembles that of a miniature tree.

Epicalyx of 3 separate leaves. Calyx 5-cleft. Fruit deprcsscd-

 when ripe into l-scededindchiscent cocca.
