 For example, other non-bulbous plant groups, like various genera within the subfamily Agavoideae, are well known to produce bulbils that do not actually meet the botanical criterion to be considered a bulb.Within Agavoideae, bulbils develop on the inflorescence of a blooming plant.The development of bulbils in this group is common in approximately 17 "Agave" species, all "Furcraea" species, and has been somewhat documented in "Yucca" (particularly "Yucca elata"), and "Hesperaloe".
