They are native to temperate areas, with a breakdown of 52 species in Europe, 30 species in North America, 78 in Asia, 24 in tropical East Africa, and 24 in temperate South America.

Tragacanth Tragacanth is a natural gum obtained from the dried sap of several species of Middle Eastern legumes of the genus "Astragalus", including "A. adscendens", "A. gummifer", "A. brachycalyx", and "A. tragacantha". Some of these species are known collectively under the common names "goat's thorn" and "locoweed". The gum is sometimes called Shiraz gum, shiraz, gum elect or gum dragon. The name derives from the Greek words "tragos" (meaning "goat") and "akantha" ("thorn"). Iran is the biggest producer of this gum.
