description

Crassula longipes is an upright herbaceous plant that reaches heights of growth of up to 2.5 centimeters. The lanceolate to wrongly lanceolate leaves are 2 to about 5.5 millimeters (rarely from 0.3 millimeters) long. The tip of the spade is pointed to blunt.

A four-fold flower is formed per node , which stands on a flower stalk about 1.5 to 3 millimeters (rarely up to 8 millimeters) long . The more or less triangular sepals are 0.4 to 0.7 millimeters long and 0.3 to 0.6 millimeters wide. Their triangular, pointed petals have a length of 1.1 to 1.7 millimeters and are 0.4 to 0.6 millimeters wide. They are longer than the sepals. The thread-like nectar flakes are 0.4 millimeters long.

12 to 14 elongated, reddish brown, slightly ribbed seeds are formed per carpel . They are about 0.25 to 0.32 millimeters long and 0.15 millimeters wide.
