Umbilicus horizontalis
Encyclopedia
Horizontal navelwort is a fleshy perennial flowering plant
in the stonecrop family Crassulaceae
(in the genus
Umbilicus
) native to the eastern Mediterranean region in rocky habitats.
Horizontal navelwort grows to an average of 25 cm (10 in) high. The thickly clustered, bell-shaped flowers are pale green, and grow in a raceme
perpendicular to the spike, unlike common navelwort
, whose flowers droop (thus the term "horizontal").
The plant often grows on shady walls or in damp rock crevices that are sparse in other plant growth, where its succulent, dark green leaves develop in rosette
s that are about 7 cm (3 in) wide. Horizontal navelwort is similar to common navelwort in many respects, but is noticeably more succulent.

Raceme
A raceme is a type of inflorescence that is unbranched and indeterminate and bears pedicellate flowers — flowers having short floral stalks called pedicels — along the axis. In botany, axis means a shoot, in this case one bearing the flowers. In a raceme, the oldest flowers are borne...
