Order Proteales

The order Proteales contains the lotus (Nelumbonaceae) and sycamore (Platanaceae) families, each of which has a single species known to be native or naturalized in New York.

Family Nelumbonaceae

The Nelumbonaceae (lotus family) has two species of aquatic plants found in New York.

Nelumbo

Nelumbo lutea, Sodus Bay, Homer D. House, State Botanist, 1916

Nelumbo lutea (American lotus) is a North American native that was probably introduced to New York from further south prior to widespread European settlement. Early botanists considered Nelumbo lutea to be native to the area around Sodus Bay, but it may have been cultivated there by Native Americans using plants brought from the South. It is now extirpated from that area, but naturalized pants persist elsewhere in the state.

Nelumbo nucifera (sacred lotus) is from tropical Asia and has been excluded from the New York Flora Atlas. It is likely to be cultivated and would be considered invasive if allowed to naturalize.

Family Platanaceae

The Platanaceae (sycamore family) is represented in New York by the native American Sycamore and the London plane tree, which is probably a hybrid of the American Sycamore (Platanus occidentalis) and the Oriental plane (Platanus orientalis) from Eurasia.^[1] Although widely planted as a street tree, the London plane tree is not known to naturalize extensively in New York.

Platanus

Platanus occidentalis

Sycamore is a common wetland and riparian tree and is among the largest of the eastern deciduous trees. Sycamores are among the fastest-growing trees in the region and reach the largest diameter of any North American hardwood.^[1] The New York State Champion sycamore tree was reported in Dutchess County in 2011 at 117 feet tall, with a circumfrence of 27 feet.^[2]

Pachysandra

Pachysandra terminalis - Japanese pachysandra

Japanese pachysandra is widely planted as a ground-cover and tends to persist, spreading vegetatively to adjacent wooded areas, where it can be difficult to remove.
Allegheny pachysandra is planted as a "native" substitute, and is probably unlikely to naturalize as far north as New York State.^[1]

↑ New York Metropolitan Flora Project, 02/07/2012 considers reports of naturalized Pachysandra procumbens to have been based on planted specimens.

Family Altingiaceae

The Altingiaceae (sweetgum family) contains only about fifteen species and its segregation from Hamamelidaceae has only recently been widely accepted. One of its three genera (Semiliquidambar) may comprise intergeneric hybrids of the other two (Altingia and Liquidambar), so revisions within this family may be forthcoming.

Liquidambar

Liquidambar styraciflua

Liquidambar styraciflua is the only North American species of Liquidambar, or sweetgum. It is most common in the forests of the southeastern United States, but its native range appears to extend as far north as southeastern New York State. It is cultivated elsewhere in the state and seems to be able to naturalize in some upstate locations.

Rhodiola

Rhodiola rosea

In New York, Rhodiola consists of two species of endangered plants.

Rhodiola integrifolia ssp. leedyi is an isolated subspecies of a common western cliff-stonecrop species (transferred from Sedum integrifolium in 1999). It has been found mainly on northwest-to-northeast-facing cliffs in southeastern Minnesota and near the southern part of Seneca Lake. It was discovered at Watkins Glen State Park in Schuyler County in 1918. The largest known population (at least 6000 plants) was discovered that same year, along about 2 miles of Glenora Cliff, on the western shore of Seneca Lake, in Yates County. It wasn't until 1994 that a third New York population was found near Glenora Falls, also in Yates County.^[1]^[2]

Myriophyllum

The subgeneric system used here for Myriophyllum is based on Michael L. Moody and Donald H. Les (2010). "Systematics of the Aquatic Angiosperm Genus Myriophyllum (Haloragaceae)." Systematic Botany, Vol. 35, No. 1 (Jan.-Mar. 2010), pp. 121-139.

The three Myriophyllum species M. spicatum, M. heterophyllum, and M. aquaticum are listed as invasive in New York State.

Myriophyllum subg. Brachytheca

Myriophyllum heterophyllum

Although Myriophyllum heterophyllum (variable-leaved water milfoil) is listed as native to New York, in is also listed as very highly invasive and prohibited by state regulations.
