PLANTS GROWING IN DRY SOIL. 293 
Black-eyed Susan, or Susie, as her playmates call her, is a 
beautiful wild country girl with a striking brunette face, and a 
gown of yellow and black, which fairly makes the meadows 
dance with life and gaiety. Perhaps she lacks that wealth of 
charm which cultivation gives, and is rather careless in choos- 
ing her companions. No doubt she is governed entirely by her 
love of fun. Her manner of growth is certainly ungraceful and 
her leaves and stem are rough and uncouth. 
She is perfectly at home in the east, although she first came 
to us hidden in clover seeds from the west; where she is called 
by the unpoetical name of “ nigger-head.”’ 
The southern rudbeckia (Plate CLI) is a more gorgeous 
flower, the cone of disk-flowers being much higher and the 
leaves broader than those of the above species. 
R. Brittoniz, Britton’s cone-flower, has flower-heads that are 
from two to three inches broad. Its-.rays are two-lobed and 
about twelve in number. They are tipped with purple. The 
stem leaves are nearly oval and often occur with a lateral lobe. 
In the mountains of Pennsylvania, Virginia and Tennessee and 
in the woods it blooms abundantly from May until July. 
The plant is stout and vigourous and it bears, as will be 
noticed, the name of Dr. Britton, who has expended so much 
time and affection upon the floral world.

Perhaps this is the most common of all the golden-rods that 
abound in dry fields. The flowers grow in.a dense plume, or 
compound panicle, along the upper side of the stem ; and the 
few tapering leaves are of a dull greyish green. It seldom 
grows over two feet high. ‘The simple stem has a cottony look. 
S. Canadensts, Canada golden-rod, is a tall species with spread-
