Order Vitales

The order Vitales contains the single family Vitaceae.

Family Vitaceae

The Vitaceae (grape family), in New York State, consists of Vitis (grapes), Parthenocissus (creepers), and Ampelopsis (porcelainberry)

Vitis

Vitis riparia (river grape) Although they are often treated as weeds, most wild grape vines found in New York are native plants that provide good nourishment for wildlife. Their problem stems from their tendency to dominate trees and shrubs on forest edges. Due to the fragmented state of much of New York's woodland, the edges comprise a large portion of the forest that most people experience. Many of what we consider natural areas or family woodlots are primarily forest edge, giving grape vines an undesired advantage over native trees and shrubs. Grapevines don't tolerate shade well, so they are easy to control in an established woods. It may be beneficial to allow grapes to dominate exotic invasive trees and shrubs.

Parthenocissus

Parthenocissus quinquefolia Virginia creeper tendril Parthenocissus is made up of two disjunct groups: a North American clade and an Asian clade. The two North American creepers found in New York (Virgina creeper and thicket creeper) are very similar in appearence. Both have similar five-lobed leaves, but they differ in the way their tendrils attach to surfaces for climbing. Virgina creeper (P. quinquefolia) attaches using adhesive pads, allowing it to climb smooth surfaces such as smooth rocks and buildings, similar to the way Boston ivy climbs. The tendrils of thicket creeper (P. inserta) attach by twining around objects.

	Leaflets	Habit	Tendrils	Fruit	Inflorescence
P. quinquefolia Virginia creeper	dull above, pubescent below	high-climbing or on ground	several branches terminating with dilated adhesive discs	rare, smaller	central axis with 25-200 flowers in panicled groups

Order Zygophyllales

The Zygophyllales contain the two families Krameriaceae and Zygophyllaceae according to A.P.G. III (2009).

Family Zygophyllaceae

The Zygophyllaceae (bean-caper or caltrop family) contains two exotic species that are not known to truly naturalize in New York but are of concern because they are listed as invasive in parts of North America.

Subfamily Tribuloideae

Tribulus

Puncture vine Puncturevine is considered to be invasive in much of the U.S., but is not thought to have fully naturalized in much of New York. It is a weed of at least 21 crops in 37 countries and is toxic to livestock, which can also suffer injury to their mouths, eyes, digestive tracts and skin from its burrs.

Subfamily Celastroideae

Euonymus

Of the six native and naturalized Euonymus species in New York, three are native, and three have been introduced and are considered to be invasive.

Euonymus subg. Euonymus sect. Euonymus

The most common native Euonymus in New York is Euonymus atropurpureus (or eastern wahoo). It is sometimes confused with the somewhat-invasive Euonymus europaeus (or European spindle tree). The two can be distinguished by several characteristics, including:

	Euonymus atropurpureus (American wahoo)	Euonymus europaeus (European spindletree)
Leaves:	pubescent beneath or entirely glabrous	glabrous above & beneath
Petals:	wide, dark brown-purple	narrow, light green-yellow-white

Celastrus

Celastrus scandens American bittersweet The genus Celastrus contains both a fairly rare American bittersweet and a very highly invasive Oriental bittersweet. The two species, which are known to hybridize, can be distinguished by their inflorescences, which form at the ends of the branches of American bittersweet and at the joints (axils) of Oriental bittersweet. Also, the leaf margins of American bittersweet are finely toothed, while those of Oriental bittersweet are wavy.

Order Oxalidales

The order Oxalidales contains seven families, of which, only Oxalidaceae members have been discovered growing outside of cultivation in New York.

Family Oxalidaceae

The Oxalidaceae (wood-sorrel family) has traditionally been included in the Geraniales, but is now included here with phylogenically similar Rosids. The only Oxalidaceae genus known to grow in the wild in New York is Oxalis.

Oxalis

Oxalis (or wood-sorrel) species are not closely related to the several edible plants referred to as sorrel in the Rumex genus, and their visual appearance is quite different, but the taste of their leaves is said to be similar. Of the four Oxalis subgenera, only subg. Oxalis species have been found in New York.

Oxalis subg. Oxalis sect. Oxalis

Oxalis montana - northern wood-sorrel Sect. Oxalis contains several species of white wood-sorrel, of which only northern wood sorrel (Oxalis montana) is listed in New York.
