Watsonieae is the second largest tribe in the Ixioideae subfamily (which is included in the Iridaceae family) and named after the best-known genus in it — Watsonia. The members in this group are widely distributed in Africa, mainly in its southern parts. They sometimes have the typical sword-shaped leaves of the Iridaceae family, but sometimes, like in Lapeirousia pyramidalis or Lapeirousia divaricata, they are very specific. The rootstock is a corm.
