	Table of contents	Genus index	Protected species index	Invasive species index

The orders Commelinales and Zingiberales are members of the commelinids clade within the monocots.

commelinids

Arecales (palms, not naturalized in NY)

Poales (grasses, rushes, sedges)

	Zingiberales (gingers, banana, unlikely naturalized in NY)

	Commelinales (spiderwort, water hyacinth)

The monospecific order Ceratophyllales is thought to be the phylogenetic sister to all the eudicots, which include all the angiosperms that follow.

Wild Flowers of New York Part 1, Plate 7. Spider Lily, Spiderwort - Tradescantia virginiana (1918)

Spiderwort (Tradescantia) is a New World genus of herbaceous perennials, named by Carl Linnaeus in honor of John Tradescant the Elder (ca. 1570–1638). Although all spiderworts listed in New York are considered to be native to eastern North America, none are listed as New York natives by the New York Flora Atlas.

Tribe Commelineae[edit | edit source]

The Commelineae in New York include the dayflowers (Commelina spp.) and dewflowers (Murdannia spp.).

Commelina[edit | edit source]

Commelina erecta L.
slender or whitemouth dayflower

The only dayflower (Commelina sp.) listed as native to New York is Commelina erecta (slender dayflower),^[1] which is thought to be extirpated from the state.

The introduced Asiatic dayflower (Commelina communis) is fairly common in many parts of the state. It is reported to be invasive in Pennsylvania, Maryland, West Virgina, Virginia, and Kentucky.^[2]

Eichhornia crassipes
water hyacinth

Pontederia crassipes (water hyacinth) is an attractive free-floating aquatic perennial that is known to be very invasive in the south. It has been reported outside of cultivation in New York State, but it's not able to overwinter this far north. However, it may be able to grow as an annual, and there is concern that water hyacinths may eventually evolve resistance to the cold.^[1]^[2]
