Is the Loasa genus or the Ferula genus more useful to humans?
Ferula Ferula (from Latin "ferula", "rod") is a genus of about 170 species of flowering plants in the carrot family, native to the Mediterranean region east to central Asia, mostly growing in arid climates. They are herbaceous perennial plants growing to 1–4 m tall, with stout, hollow, somewhat succulent stems. The leaves are tripinnate or even more finely divided, with a stout basal sheath clasping the stem. The flowers are usually yellow, rarely white, produced in large umbels. Many plants of this genus, especially "F. communis" are referred to as "giant fennel," although they are not fennel in the strict sense.
Amphimas Amphimas is a small genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Faboideae. It is a west African tree used for medicine and for wood. "Amphimas" was traditionally assigned to the tribe Sophoreae; however, recent molecular phylogenetic analyses reassigned "Amphimas" into an unspecified position in the Meso-Papilionoideae.
