Genus Rhus[edit]

Rhus contains the sumac trees, which are all beneficial New York natives. However, the Chinese sumac or tree-of-heaven (Ailanthus altissima) in the Simaroubaceae (quassia family, below) is a potentially invasive non-native.

Genus Toxicodendron[edit]

Toxicodendron contains the native, but often unwelcome, poison ivy, poison oak, and poison sumac trio. All of these produce the resin urushiol which can cause severe skin and mucous-membrane irritation in those who have a sensitivity to it.

Toxicodendron sect. Toxicodendron[edit]

While both eastern poison-ivy (T. radicans) and western poison-ivy (T. rydbergii) are rhizomatous and may occur as low shrubs, only eastern poison-ivy has aerial roots, allowing it to also occur as a trailing or climbing liana.^[1]

Eastern poison-ivy — In North America in general, T. radicans ssp. radicans occurs primarily east of the Appalachian Mountains and can be considered as a coastal taxon, while ssp. negundo occurs primarily west of the Appalachians. In New York, ssp. radicans occurs primarily in the southeast part of the state and up the Hudson Valley, while ssp. negundo occurs in the western and central parts of the state.^[2]

T. radicans	Leaflets	Petioles	Drupes	Stems
ssp. radicans	fairly flat, underside glabrous except on main veins; tufts of hair on vein axils	glabrous	pubescent, scabrous, or papillose	may have aerial roots
ssp. negundo	fairly flat, underside softly pubescent	pubescent	usually glabrous	may have aerial roots
ssp. rydbergii	thicker, somewhat folded, underside glabrous to sparsely strigose, upper surface glabrous	glabrous	larger, glabrous	without aerial roots

Western poison-ivy — Toxicodendron rydbergii is closely related to eastern poison-ivy, and despite its morphological differences and lack of climbing ability, may still be considered a subspecies or variety of T. radicans.^[3]

Family Sapindaceae[edit]

The Sapindaceae (soapberry family) ... ^[1]

Subfamily Hippocastanoideae[edit]

Tribe Acereae[edit]

Genus Acer[edit]

The genus Acer is represented by about fifteen native or naturalized species in New York. These species are here separated into sections following de Jong (2002).^[2] These sections are further organized into three tables corresponding to the three clusters (aceroid, palmatoid, and platanoid) described by Grimm et. al. (2006).^[3]

Most Acer species go by the common name maple, and all have opposite leaves. Maples are represented by the initial letter 'M' in the mnemonic "MADCap Horse," which can be used to remember which trees have opposite leaves. The other opposite-leave trees represented are Ash, Dogwood, Caprifoliaceae, and Horse chestnut. Of course there are exceptions.

Grimm, Susanne S. Renner, Alexandros Stamatakis & Vera Hemleben, 2006. A Nuclear Ribosomal DNA Phylogeny of Acer Inferred with Maximum Likelihood, Splits Graphs, and Motif Analysis of 606 Sequences.

Aceroid sect. Acer[edit]

Sugar maple (Acer saccharum) and black maple (Acer nigrum) are often treated as conspecific, with black maple identified as a subspecies of sugar maple. There are significant morphological differences, but little genetic difference between the two trees, which commonly hybridize. So it's thought that the morphological differences may be more the result of local conditions.^[1] The range of black maple does not extend much farther east than New York, while sugar maple is common in both New England and the Mid-west.

The Eurasian sycamore maple (Acer pseudoplatanus), also in the Acer section, is not common in New York, but it can become weedy and is now prohibited due to its demonstrated invasive potential.

Palmatoid sect. Negundo[edit]

Box-elder (Acer negundo) is a common, often weedy tree that may be native to only the south-central portion of New York State, in the vicinity of Binghamton and Ithaca. Elsewhere in the state it is considered to be introduced. Box Elder is considered to be introduced and invasive in parts of Canada.
