The first pair of Rosales families on this page (Rhamnaceae and Elaeagnaceae) contain several small trees and shrubs that are particularly invasive in many parts of New York. These include the autumn olive, Russian olive, common buckthorn, and glossy buckthorn.

Family Rhamnaceae[edit | edit source]

The Rhamnaceae (buckthorn family) in New York contains three species of native shrubs (two New Jersey tea and one buckthorn species). It also contains two highly invasive non-native buckthorns, both of which are prohibited in New York.[1][2]

Subfamily Rhamnoideae[edit | edit source]

Tribe Rhamneae[edit | edit source]

Besides the two highly invasive exotic buckthorn species, the Rhamneae tribe contains the native alder-leaved buckthorn.
Rhamnus[edit | edit source]
Native alder-leaved buckthorn (Rhamnus alnifolia).

The native alder-leaved buckthorn (Rhamnus alnifolia or Endotropis alnifolia)[1][2] should not be confused with the invasive exotic "glossy buckthorn" (Frangula alnus), which also goes by the similar common name "alder buckthorn."

The two non-native buckthorns Rhamnus davurica and Rhamnus utilis have not been reported as naturalized in New York, but they have been reported outside of cultivation in neighboring states.

Frangula[edit | edit source]
Invasive Frangula alnus
Glossy buckthorn
The only Frangula species reported in the wild in New York is glossy buckthorn (Frangula alnus), which is an Old World species that is considered highly invasive and is prohibited in New York. Frangula alnus is sometimes known as "alder buckthorn" and as noted above, should not be confused with the native Rhamnus alnifolia.

The seven or so North American Frangula species have not been reported in New York, but Carolina buckthorn and perhaps others may be able to survive cultivation in parts of the state.

Humulus[edit | edit source]

Humulus lupulus var. lupuloides
Northeastern hops
At least two species of wild hops are present in New York, depending on how they are recognized taxonomically. Of the three varieties of common hops (Humulus lupulus) found in New York, two (var. lupuloides and var pubescens) are considered native and one (var. lupulus) is European. A fourth variety (var. neomexicanus) is also native to North America but has not been reported in the wild in New York. Although similar in appearance, based on molecular and morphological studies, these four varieties can also be treated as separate species (H. lupuloides, H. pubescens, H. neomexicana, and H. lupulus s.s.).[1][2]

Morus rubra
red mulberry fruit
Of the dozen-or-so species of mulberry trees found worldwide, two have been found in the wild in New York. The red mulberry (Morus rubra) is native to eastern North America, including New York, and the white mulberry (Morus alba, the primary host for silkmoth caterpillars) was introduced from eastern Asia and is known to escape cultivation. M. alba is considered to be invasive in Mid-Atlantic states.[2]

Urtica[edit | edit source]
Urtica gracilis ssp. gracilis
Many sources treat Urtica gracilis, the American stinging nettle, as a subspecies of Urtica dioica, which contains the European stinging nettle. Henning et al. (2014) proposed the transfer of the North American U. dioica subtaxa to U. gracilis, the holotype of which was collected on the Hudson Bay.[1]

U. gracilis differs from U. dioica in that the native plant is monoecious and has a less dense population of stinging hairs than the European species.
