The inflorescence arises on several stems up to about 30 centimeters tall, each stem bearing an array of up to 100 flowers each. Near the flowers are small, pointed bracts tipped with shiny spherical resin glands. The flower has 4 to 11 petals, each up to about a centimeter in length and oval in shape with a notched tip.
