Narrative

Plants show a highly elongated hypocotyl and minimally elongated epicotyl at seedling emergence. Plant expresses nyctinastic leaf movements with both the pinnae and petiole moving downward at night. The cotyledons as well as the leaflets undergo upward nyctinastic movement. Plant is not seismonastic. Although this plant will flower in the spring, will not flower in the spring of the year of establishment. Plant height varies with rainfall, but under reasonable moisture and growing conditions, plant will grow to a height of 1.25 to 2.5 meters. Plant becomes woody at base as matures, and develops a cylindrical, woody, branched taproot. Begins flowering in late August or early Sept. Flowering and seed set can be greatly modified by drought and heat stress, and if soil or water variation exists within a field, flowering within a field can be modified by several days to more than two weeks. Flowers are round heads or condensed spikes born 1-2 in the axils of the leaves. Plant flowers profusely and will set pod in clusters of 8 or 9 pods per cluster. Each pod about 13 to 15 seeds that will weigh 0.54 to 0.65 grams per 100 seed. Fruit shape linear; endocarp elaborated into hair-like structures between the seed; and distal end of legume fruit has an attenuated beak. Pods dehiscent along both sutures. Leaf color green to dark green (5 GY 4/4 to 7.5 GY 4/4). Stem and pods tend to turn red (5R 3/4) in the fall as temperatures cool down. Immature pods mostly green, but as pod starts to mature turn red on the upper surface. Leaf bipinnately compound with about 6 pairs of pinnae per leaf and about 24 pars of leaflets per pinnae. Petiole length about 65 t0 75 mm and the longest pinnae about 35 to 40 mm. Stipule length about 3.5 mm. Fully mature seed brown (2.5 YR 3/4).
