Orange, yellow and scarlet.
New Jersey south-ward and westword.
Flowers: very showy; axillary; growing in terminal corymbs. Calyx: five-toothed. Corolla: two and a half inches long; trumpet shaped with five lobes, veined on the inside. Stamens: four, in pairs, two shorter than the others. Pistil: one. Leaves: odd-pinnate; opposite; with four or five pairs of ovate pointed, toothed leaflets. Stem: woody, climbing by aerial rootlets. Pod: long, a little flattened.
To watch the way in which this bold vine climbs by means of the aerial rootlets that spring from the stem, is a good lesson in moral philosophy. It appears to take vigourous delight in its upward course, and in showing us its belief in the survival of the fittest, by crushing out any weaker plant that comes within its reach. We almost take a step backward to view it from a safer distance.
Its abundant growth and the difficulty in extirpating it makes it a rather troublesome weed in some of the western states. In the east it is cultivated as one of our most beautiful climbers.
