Flowers are available with plain tepals and ruffled tepals .
However, these authors did not observe the initiation of tepals and stamens on the same whorl on individual flowers.
The six subequal tepals are arranged in two whorls and horizontally spread.
The blossoms vary in the number of thick tepals , or petals, and last only two to four days.
The flower closing occurs through upward movements of the tepals , which return to their bud position.
