Description
''Ellisia nyctelea'' is an annual plant that grows to tall. Lower leaves are arranged oppositely on a somewhat succulent stem, while upper leaves are alternate. The hairy leaves are typically long by wide and are deeply lobed or divided, with seven to 13 lobes or leaflets on each leaf.
The small flowers are found on short slender stalks arising from the leaf axils. Each flower has five white or light blue petals that are united at the base to form a tube; these may be streaked or dotted with purple coloration. The calyx is hairy, green, and has five large teeth.[
