BELLFLOWER, LOBELIAS AND GOODENIAS. 59 
to two genera, Helichrysum and Helipterum, so called because 
some species of the former with golden-yellow flower-heads 
resemble the sunflower in miniature, while the Helipterums differ 
in having not the denticulated pappus-hair of Helichrysum, but 
plumes forming the pappus. Thus these two genera differ almost 
from each other like the ordinary Thistles from the Plum-thistles. 
The name of the ordinary large and yellow-flowered everlasting is 
Helichrysum lucidum. The ray of these plants is formed by the 
inner elongated bracts (or involucre-scales), not by the outer 
flowers as in Chamomiles, Chrysanthemums, Asters, Daisies, the 
Capeweed (Cryptostemma calendulaceum) and many other 
genera of Composites. The bracts of everlastings may vary 
white, pink or yellow in the same species. A dwarf perennial 
composite herb, with leaves reminding of those of Primroses, and 
with small yellow ray-flowers frequents our pastures; this is 
the Cymbonotus Lawsonianus ; it is geographically remarkable 
as the only plant of the large Arctotis-tribe known as indigenous 
beyond Africa. The enormous genus Senecio, counting nearly 
one thousand species in all parts of the globe (absent in North 
Australia), is represented in our colony by many and chiefly 
yellow-rayed species. The involucre consists only of one series 
of bracts, which are connate and give the appearance of a calyx. 
The Cineraria of the Canary Islands (Senecio cruentus), which is 
such a favorite for window-culture, demonstrates well the general 
structure of these kinds of plants; they as a rule possess a 
peculiar somewhat aromatic odor. 
IX.—THE BELLFLOWER, LOBELIAS, GOODENIAS 
AND ALLIED PLANTS. 
AUSTRALIA possesses of the beautiful genus of Bellflowers only 
one species, Campanula gracilis, and this plant, when growing 
copiously gives occasionally to our meadows that blue tint, which
