 from Chili growing 3 to 4 ft. high, with 

 clusters of snowy white flowers. 



C. amplexicaulis. A fine kind with 

 soft green leaves clasping the stem and

 in autumn. Ecuador. 



C. hyssopifolia. One of the best of 

 the dwarf kinds, bearing loose clusters

 numerous small brown dots top of the 

 stems. Its foliage resembles a Mimulus, 

 creeping along the ground, and it is a 

 very interesting dwarf rock-garden plant.

 4 ft. high, with large light-green, nmch- 

 wrinkled foliage, bearing large, pale- 

 yellow, slipper-shaped blossoms. It is a

 autumn and winter flowering. The petals 

 were formerly used to flavour dishes in 

 old English cookery, hence its name.

 and may be sown in the open ground 

 either in spring or autumn. There are 

 now pretty varieties, single and double.

 small hardy trailing Arum, with white 

 spathes. Flowering in summer, and in-

 of the best plants, but its beauty is best 

 seen when it is allowed to ramble over 

 rich muddy soil. N. America and N.

 districts. Australia. 



CALLISTEPHUS (China ^ Aster). 

 Among the many annuals now in cultiva- 

 tion China Asters (C. chinensis) are among 

 the best, and when well grown and cared 

 for they do as much to adorn a garden 

 during summer and autumn as any 

 annual plant. To see them in their beauty, 

 however, they must be grown in masses, 

 and well cultivated not at any stage left
