Two landraces, one tested

Leafly calls both landraces: Durban Poison a pure sativa from Durban, Lamb’s Bread “a landrace from the island of Jamaica”.2,7 Only Lamb’s Bread has been put to a genetic test in the literature we found, and the one sample sold under the name turned out nearly identical to an Afghan indica (see genetics).8
