and leafy stems, and an abundance of pale purplish 

 wide-open bloom, large for the size of the plant. 

 Most of the Thistles, however handsome in leaf, are 

 disappointing in flower. This good plant, on the

 penta; and of smaller plants, Anomatheca cruenta, 

 Anemone fulgens y and in the south, Amaryllis Bella-

 power of assimilation with the forms and surfaces of 

 ancient buildings. For a permanent covering of any- 

 thing ugly of brick or stone it is also a most helpful 

 auxiliary, and though I am just now considering ways
