Sorbus

The mountain-ash trees in the genus Sorbus are not closely related to the ash trees of the genus Fraxinus and as such are not subject to the ravages of the emerald ash borer. The use of the term "ash" is probably due to the superfical similarity of the compound leaves. The mountain-ashes are more closely related to the hawthorns, apples and crabapples, which are also in the Maleae tribe.

Sorbus sect. Sorbus

There are two native mountain-ash trees in New York,.

The European mountain-ash, or rowan, is a commonly-planted ornamental tree that does naturalize in the state. European mountain-ash trees can be distinguished from the American species by the long villous hairs on the undersides of the leaves as well as on the twigs and bud scales of the European species.

Malus

Malus contains the apples and crabapples, one species of which (the sweet crabapple) is considered to be native to New York.

Malus sect. Chloromeles

Malus coronaria The sweet crabapple (Malus coronaria) has in the past been treated as a number of separate taxa, but most modern sources treat them as a single species. This is the only New York native crabapple and probably the only North American native crabapple found in the wild in New York. The native crabapple is not widely planted due to its susceptibility to cedar-apple rust (Gymnosporangium juniperivirginianae), cedar-quince rust (G. clavipes), and cedar-hawthorn rust (G. globosum).

Malus sect. Malus

Section Malus contains the common domesticated apple (Malus pumila or Malus domestica) along with a number of Eurasian crabapples. Qian (2010) proposed conserving Malus domestica as the acceped name of the domesticated apple.[1] It is important to note that apples are extremely heterozygous, resulting in naturalized apples that bear little resemblance to domestic apples, which are generally propagated by grafting.[2] So the presence of apples in the wild that look and taste like cultivated apples is usually the result of long-living planted apple trees being subsumed by the wild and not by apple seeds being spread into a natural area.[3] ↑ Guan-Ze Qian, Lian-Fen Liu and Geng-Guo Tang (2010).

Pyrus

Pyrus communis common pear Pyrus contains two species of pears that have naturalized in New York. The common pear (Pyrus communis) is grown for its fruit and occasionally escapes or persists from cultivation. The Bradford or Callery pear is widely planted as an ornamental tree, but has been found to naturalize in some locations, particularly in Suffolk County.
