SPECIES I— LAVATERA ARBOREA. Linn. 

 Plate CCLXXIX. 

 Reich. Ic. Fl. Germ, et Helv. Vol. VI. Malv. 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 Pirth of Clyde. Often culti- 

 vated ; and as it becomes readily natiu-alized, it is to be found in 

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

 on other islands in the Pirth of Porth. 



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. Plowers \\ inch across, pale purple with broad dark veins 

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

 the extremity of the stem and branches. Ej)icalyx very large, with 

 3 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 

 pale olive, flat on the sides, with radiating wrinkles ; the sides 

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

 reticulated with elevated lines, glabrous. Pruiting calyx closely 

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

 of stellate hairs. 



The enormously large epicalyx with 3 ovate obtuse lobes 

 sufiiciently distinguishes this from the other British ZMalvacese, 

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

 resembles that of a miniature tree. 



Tree Mallow. 



French, Lavatere en Arhre, 



GENUS 7J7.— MALVA. Linn. 



Epicalyx of 3 separate leaves. Calyx 5-cleft. Pruit depressed- 

 orbicular. Carpels without a beak, separating from the torus 

 when ripe into 1-seeded indehiscent cocoa.
