Leaves long ovate to lance-shaped, the lower ones tapering to margined petioles, the upper ones smaller, acute, and ses- sile. Flowers in loose panicles, usually dioecious, numerous, white or often tinged with pink, fragrant, each about an inch broad, opening in the evening and closing after sunrise the next day; each of the five petals is deeply notched at the outer edge, and at the inner point is a pair of white, scale-like bracts, narrowing the throat of the flower which is fertilized by long-tongued, night-flying moths.
