Flowering from March to July, this plant produces white flowers tinged with red to purple, delicately arranged in umbels. Growing with glandular-puberulent stems less than 5 centimeters tall, it has a distinctive scapose habit. Its simple opposite leaves are 10 to 15 centimeters long, with kidney-shaped or heart-shaped blades that are crenate or shallowly lobed, featuring a blade much smaller than its petiole. The distinctive fruit consists of glandular-puberulent mericarp bodies 8 to 10 millimeters long with a persistent style column and stiffly hairy beak segments.
