 Channel Islands. 



Great liurnet, with its tall purple llovverheads, is a conspicuous plant 

 in most meadows laid to j^rass in the summer. In meadows, fields, 

 and pastures it orows side by side with Yellow Rattle, Sorrel, Saw- 

 wort, Field Scabious, Ox-eye Daisy, &c. 



Quite a familiar sight in the meadows in summer, the tall erect 

 stems of the Great Burnet are branched, with egg-shaped, half-heart- 

 shaped leaflets, the leaves smooth, the lobes one each side of the 

 common stalk, and distant or few. 



Deep purplish-brown, the heads of flower are conspicuous amid 

 the green sea of wild flowers and grasses in a meadow. The spike 

 is egg-shaped or oblong, with calyx and stamens of the same length, 

 the latter not shorter than the sepaloid calyx, which is smooth. In fruit 

 the calyx is four-winged in the upper part. 



Two to three feet Is the height of this species. It flowers from 

 June to August. A deciduous, herbaceous perennial, it is propagated 

 by means of seeds. 



The flower has no corolla, and the caly.x does duty for petals. 

 This in the lowest part (and the middle belongs to the tube of the 

 receptacle) surrounds the ovary, and the middle part, a fleshy ring 

 round the base of the style, secretes honey, while the upper part 

 spreads out into four dark-purple, sepal-like lobes. The anthers and 

 stigmas develop together. The plant is monoecious, the se.xes being 

 on the same plant. The flowers are pollinated by insects, unlike P. 

 satignisorha, though the stigma is divided as in a wind-pollinated 

 flower, and the character is doubtless inherited from a wind-pollinated 

 ancestor resembling Poterimu. 



The fruit is dispersed by wind, the caly.x is four-winged and 

 encloses the achenes or fruits, helping to disperse them by the wind. 



Being addicted to a sand soil it is sand-loving, or clay-loving, and 

 found on a clay soil, but it usually grows on sandy loam. 



Burnet leaf-spot, Xcucdoclins carbouariits, is j^arasitic upon it.
