Sedella is a genus of plants fromthe thick-leaf family (Crassulaceae). The botanical name of the genus is a diminutive of the name of the genus Sedum and refers to the very small size of the plants.
description
The species of the genus Sedella are annual , bare plants that usually branch out with often red or reddish shoots that are usually less than 10 centimeters long. Their sitting leaves are opposite to the base of the shoots and alternately above them. They are elongated ovoid to obovate and blunt to rounded. The leaves usually fall off before flowering.
The terminal zymous inflorescence consists of one to several branches, with the wraps rolled up almost in a circle. The upright, almost sessile flowers are five-fold and are located on very short flower stalks. The same sepals are erect and almost free. They are triangular in shape, pointed and not spurred. The bright to light or greenish yellow petals often have a reddish midrib and are much longer than the petals.
The nut-like fruits are club-shaped, thin-skinned and do not tear open. They each contain an elongated, clubbed, longitudinally striped seed 0.7 to 1.5 millimeters in size.
