Order Vitales edit

The order Vitales contains the single family Vitaceae.^[1]

↑ Vitales in P.F. Stevens (2001 onwards). Angiosperm Phylogeny Website. 15 July 2015.

Family Vitaceae edit

The Vitaceae (grape family), in New York State, consists of Vitis (grapes), Parthenocissus (creepers), and Ampelopsis (porcelainberry)^[1]

The tribal classification used here is based on Jun Wen et al. (2018).^[2]

Tribe Ampelopsideae edit

Ampelopsis s.l. was shown to be paraphyletic in recent phylogenetic studies and was split into the two genera: Ampelopsis s.s. and Nekemias.^[1]

Ampelopsis edit

Ampelopsis glandulosa

The two North American peppervine species Nekemias arborea and Ampelopsis cordata are not known to naturalize in New York State, but two native Chinese Ampelopsis species, including the highly invasive porcelain berry (A. glandulosa), have been found to naturalize in the southeastern part of the state and more recently in the Finger Lakes region.^[1]

Tribe Cayratieae edit

Tribe Cayratieae contains the genera: Cayratia, Causonis, Pseudocayratia, Acareosperma, Cyphostemma, and Tetrastigma,^[1] none of which are known to have naturalized in New York State, but Causonis japonica (Thunb.) Raf. (bushkiller) has been reported in adjacent states and would be considered highly invasive in New York.

Tribe Viteae edit

Vitis edit

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.

Tribe Parthenocisseae edit

Parthenocissus edit

Parthenocissus quinquefolia
Virginia creeper tendril

Parthenocissus is made up of two disjunct groups: a North American clade and an Asian clade. ^[1]

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.

Euonymus subg. Euonymus sect. Euonymus edit

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 edit

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 edit

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

Family Oxalidaceae edit

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 edit

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 edit

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.

Oxalis subg. Oxalis sect. Corniculatae edit

Oxalis stricta
common yellow wood-sorrel

Sect. Corniculatae contains the North American yellow-flowered caulescent Oxalis species, five of which are found in New York. This section has also been treated as the separate genus Xanthoxalis.^[1]

Recent research has suggested that Oxalis corniculata (arguably the weediest of this section) is likely to be a native of southeast Asia.^[2]

Oxalis exilis, a native of New Zealand and Tasmania, was reported in Jones Beach State Park in 2011.^[3] That identification seems to be in question however.^[4]
