Umbrella Thorn Acacia

Acacia tortilis

Description:

Branches of acacia trees have both short hooked spikes and long straight spines with feather-like leaflets. Flowers are white or pale yellow in color and form a ball-like cluster on the end of a short stem. Seeds pods of A. tortilis and A. raddiana are curved, twisted like a spiral. Leaves and pods of A. tortilis are covered in hairs, but A. raddiana's are not.

Habitat:

Generally, acacias grow in rocky or sandy wadis and crevices. A. raddiana does not grow well at higher elevations, but has been recorded up to 1400 m in Sinai. A. tortilis is very resistant to drought and salinity, but grows taller on non-saline soil. Acacia spp. are common throughout the lower elevations of Sinai.

Notes:

Either Acacia tortilis subsp. raddiana OR Acacia tortilis subsp. tortilis

Thanks, Sachin! It is one of my favorite trees to photograph. I love the contrast between the reddish branches, green leaves, and white spikes and flowers.
