372 The child who brings me the oddities of vegetable forms is knowing in the normals of his class of curiosities, or else he would not see the novelties from the finding and exhibiting of which he gains so much pleasure. The person who is familiar with the striking beauty of the cardinal flower (Lobelia cardinalis) is the one who rejoices at the variations that may occur in the tints of the bright corolla. His delight would reach a high pitch should the conspicuous spikes be found upon dry ground, and not by the bank of some stream half hidden by the overhanging grass. But should the wandering plant display white flowers, then an albino of a most interesting kind has been met with, and some reason for it is sought in the unusual locality. Only a few days ago a white variation of the Lobelia syphilitica, cousin to the cardinal, was seen by the writer treasured in the Botanical Garden at Cambridge, Mass., and it called to mind the rage for pink water lilies, that twenty years ago were only met with wild in ponds at Plymouth, Mass. I asked an expert recently if there was any call for the pink or "Plymouth" lilies, and he informed me that the fad had died out with the transplanting and widespread culture of the pink "sports" of the nymphæa ponds.

Abnormal colors in flowers are among the most common freaks in wild plants, and none are more frequent than the albinos. One could fill a page with instances of this sort. Some of our most common weeds, as the moth mullein (Verbascum blattaria), have a large percentage of the plants with white blossoms, and the patches of the white interspersed with the normal yellow-flowered plants in poorly kept meadows and neglected land has led the writer to gather seed of each to test the truth of the opinion that the white strain may be transmitted to the offspring, but the proof is not yet at hand.

The writer knows where there is a patch of the hound's tongue (Echinospermum) with a good sprinkling of plants producing white corollas instead of the normal deep maroon. The two colors make a good subject for students who are gaining an elementary knowledge of the stability of species, and the range of striking variations that must be allowed for them,

Next to the albinos the instances where the floral parts approach leaves in size and color are the most common. A few weeks ago while passing through a field once devoted to corn, but now overgrown with weeds, and therefore of special interest to a botanist, my eyes fell upon a daisy plant all the heads of which were with olive-green ray flowers instead of the ordinary pure white ones. These rays were smaller than the normal and quite inclined to roll, as shown in Fig. 1, and form quills, as seen in some of the fancy chrysanthemums. By the way, our common field daisy is a genuine chrysanthemum and that which is produced in one species under
