The little pointed scollops that rim the cup suggest these petals. Now, the tiny cup is descended from a five-petaled ancestor, growing upon its individual stem and depending upon insects for its fertilization. The flower was small, however, and many of them must have been overlooked by the insects
But those blossoms that, growing very close together, formed little clusters, were more conspicuous than the solitary ones, and were discovered, visited for their honey and incidentally fertilized by the winged freebooters. These blossoms bore fruit and their descendants inherited the social instinct prompting them to draw together that each might give the other its help and co-operation in attracting the insects. So, by degrees, the co-operative habit became fixed in the clover, and in many other plants, until the compositæ became a botanical fact. In other words, the individuals formed a body social of their own, growing from a compact cluster from a common stem, each giving and receiving, constantly, its use and share in the common life. The many-petaled flowers found it inconvenient to arrange themselves in the composite order, and so, as we see in the clover, the petals have pressed closely together and united to form a tube-shaped flower, and as the tubular form is best adapted to receive fertilization by the bee, which insect is the most useful to the clover blossom, that form has been perpetuated in this plant.
Thus by the simple process of each individual giving itself to the common life, the mutual protection and development of the whole, this order of plants has become the largest in the floral kingdom. The compositæ have circled the globe. They fill our hothouses and flourish in our gardens; they greet us by the dusty road, and in the summer woods. The lovely golden-rod, the sturdy asters, the aristocratic chrysanthemums, the dainty daisies all belong to this great order. So does helianthus, the big, beaming sunflower.
It is quite true that each blossom of the compositæ has given its life to the race. But what if, after all, life with our fellows is a giving instead of the receiving we are wont to think it?
What if, after all, the true outlook upon Society will one day show us that our neighbor is put here that we may have the great, the inestimable joy of living for him?
