Monocots

 1. Acorales                                                                                                                                                               Wikipedia

Inflorescence spadix with spathe; leaves axils with mucilaginous intravaginal squamules ovules atropous, seeds with epidermal perisperm and copious endosperm ethereal oils

  2. Alismatales

Mostly herbs and aquatics; rhizomatous infl ± scapose; G often apocarpous placentation often laminar; endosperm helobial 

  3. Dioscoreales

Twining vines (often); leaves often reticulate ovary often inferior, style short, branched steroidal sapogenins/alkaloids

  4. Pandanales

Some woody (with terminally tufted lvs) infl sometimes with spathe + spadix

  5. Liliales                                                                                                                                                               Wikipedia

Geophytes (bulbs, tubers, rhizomes); leaf bases often not sheathing flw T sometimes spotted, nectaries on T, anthers extrorse seeds ∞ phytomelan lacking; fructans in stems, chelidonic acid

  6. Petrosaviales

Stem with ring of bundles; fr follicle; East Asia

  7.  Asparagales                                                           Wikepedia: General, Families

Often geophytes fr capsule or berry seed coat obliterated or with phytomelan

  8. Arecales

Woody, often monopodial lvs often palmately or pinnately pseudocompound, reduplicate-plicate intense primary growth, large apical meristem, infl often with spathe alkaloids

  9. Poales                                                                                                                                 Wikepedia

Herbs (mostly); lvs grassy; epidermis siliceous mycorrhiza – (in most) flw often anemophilous, minute, chaffy, without nectaries

 10.  Commelinales

Inflorescence thyrsus or scorpioid cymes flower monosymmetric or not, stamens few fertile phenylphenalenones  

 11. Zingiberales

Herbs, rhizomatous, large-leafed; pseudostem common flw irregular/monosymmetric, septal nectaries A often strongly modified/reduced, G inferior; seeds often arillate
