"Full many a flower is born to blush unseen
And waste its sweetness on the desert air."

The little yellow blossom has, so far as the writer knows, no name in the text-books on botany. It is a tiny blossom, growing very close to the ground, and it opens only at night. Then, whoso chances to pass through a patch of these flowers is treated to incense such as never exhaled from the most redolent orange orchard.

The perfume is given off in vast quantities, and is sweet beyond the power of language to describe, yet it is not the sickening, overpowering perfume of some plants.

One does not need to lift the flower to the face to get the fragrance,—the air is fairly saturated with the sweet odor. The daylight, however, puts an end to both blossom and perfume. There is not a sign of the blossom to be found when the morning sun lights up the desert plain. It is only the night traveler who is favored with the sweet experience arising from an acquaintance with this strange plant.
