description

The species of the genus Sinocrassula are hapaxanthe , annual , biennial or perennial , succulent herbaceous plants . They are bald or papilose and rarely downy-haired. The plants are patterned with reddish brown thin lines or points. Their roots are fibrous. The rosettes, which usually dissolve during the flowering period, reach a diameter of up to 10 centimeters, but are usually smaller. They consist of about 10 to 70  leaves . The fleshy-succulent, unspired, blunt to tapering, sitting leaves are mostly alternate and only rarely arranged opposite one another. They are 15 to 40 millimeters long (rarely 8 to 60 millimeters) and 5 to 12 millimeters wide (rarely 2 to 25 millimeters). The leaf surface is often speckled.

The terminal and only rarely lateral inflorescence is equilateral. It becomes about 4 to 30 centimeters (rarely up to 60 centimeters) long at flowering time. The stalked, bell-urn-shaped flowers are hermaphroditic, five-fold and haplostemon. They are 1.6 to 6 millimeters long. Their green, somewhat fleshy, upright sepals are fused together at the base. The free, upright petals are somewhat elongated to lanceolate, fleshy and incline somewhat like an urn. They are somewhat whitish to greenish or pink and mottled more or less intensely red, orange or brown.

The fruit is an upright follicle fruit . The more or less brown, cylindrical seeds contained therein are about 0.5 to 1.2 millimeters in size and have about 10 to 15 parallel longitudinal ribs.
