| | The Classification Of Liliopsids |
 | | Liliopsida are divided into about 19 orders: Alismatales, Arales, Arecales, Bromeliales, Commelinales, Cyclanthales, Cyperales, Eriocaulales, Hydatellales, Hydrocharitales, Juncales, Liliales, Najadales, Orchidales, Pandanales, Restionales, Triuridales, Typhales, and Zingiberales. |
 | | If there is only one family in an order, this etymology is always the case: Arecales, Arecaceae; Bromeliales, Bromeliaceae; etc. |
 | | So we see that the family Poaceae is the most economically important family in the plant kingdom. |
