The order Fagales is part of the nitrogen-fixing clade:

nitrogen‑fixing clade 

Fabales




Rosales




Cucurbitales


 Fagales 

Fagaceae (beech family: oak, chestnut, and beech)





Myricaceae (bayberry family: sweet-fern and bayberry)



Juglandaceae (walnut family: walnut and hickory)




Betulaceae (birch family: alder, birch, hornbeam, and hazelnut)







However, the vast majority of species able to form nitrogen-fixing root nodules are in the Fabaceae (legume family). In the Fagales, only the Myricaceae (bayberry family) and Alnus (alder) species are able to fix nitrogen.

Fagales species primarily take the form of trees. They have also been placed in the Juglandales.

Subfamily Quercoideae

edit

The Quercoideae, as organized here, includes the oaks and the chestnuts.

Tribe Querceae

edit
Querceae currently comprises only genus Quercus. In previous schemes, the tribe also included upgraded Quercus subgenera, including Macrobalanus (large-fruited white oaks) and Erythrobalanus (red and black oaks).[1][2]

Quercus
edit
The genus Quercus contains the oaks, which comprise about 30 taxa of trees and shrubs in New York. Two sections of oaks in the subgenus Quercus are found in the state: sect. Quercus (white oaks) and sect. Lobate (red oaks). They commonly hybridized only within their own section.[1]

Quercus montana
chestnut oak
The Quercus section Quercus contains the white-oak group, most members of which have leaves with rounded lobes. White oaks produce acorns that mature in a single season and are relatively sweet.

  1. ↑ Trelease (1924) considered Q.× deamii to be Q.alba × Q.muehlenbergii. Bartlett (1951) showed that Q.macrocarpa × Q.muehlenbergii were more likely to have been the real parents of Q.× deamii. Meanwhile E.J.Palmer (1948) published the name Q.× fallax for oaks with that parentage. So now Q.× fallax is considered to be a synonym of Q.× deamii.
Quercus sect. Lobatae
edit
 
Red oak

The Quercus section Lobatae (similar to sect. Erythrobalanus) contains the red oak group, most members of which have leaves with pointed or spiny lobes. Red oaks produce acorns that require two seasons (18 months) to mature and are relatively bitter.

Note that Quercus lobata (a California native) is a member of sect. Querca, not sect. Lobatae, as might be inferred from its name.

The oaks of this group are especially susceptible to the oak wilt fungus (Bretziella fagacearum. formerly Ceratocystis fagacearum).[1]

Castanea dentata (Marsh.) Borkh.
American chestnut
Native American chestnut trees (Castanea dentata) were a major component of many New York forests until the introduction of the exotic chestnut blight fungus (Cryphonectria parasitica) in the late 19th century. Mature American chestnuts are now rare, but stump sprouts are keeping the chestnut genome alive.

  1. ↑ Castanea dentata status is misleading because although the species is not rare and will likely persist, chestnut blight prevents the trees from maturing. Most grow from root suckers.

Subfamily Fagoideae

Fagus

American beech (Fagus grandifolia)
The American beech, Fagus grandifolia, is a widespread hardwood tree in New York, and historically associated with Acer saccharum (sugar maple) in beech-maple climax forests. The American beech, however, is susceptible to beech bark disease, which is now common in New York. The disease is made possible by the non-native beech scale insect, Cryptococcus fagisuga, which pierces the bark to feed on the sap. The resulting holes allow Nectria fungus spores to enter. Eventually the exotic fungus kills portions of inner bark and induces cankers that often girdle and kill the tree.[1] Given these facts, the "secure" status for American beech may be counter-intuitive, but the loss of larger infected trees increases the number of root suckers and stump sprouts, causing dense beech thickets, which have little benefit for wildlife or timber harvesters. So, as with other disease-prone trees such as American elm and American chestnut, the threat of extirpation is low, even though the health of the existing population remains poor. In fact, foresters in New York often consider the American beech to be a native invasive or interfering species and treat beech tree stumps with glyphosate immediately after cutting to prevent such resprouts.[2]

Family Myricaceae

edit
The Myricaceae Blume 1829 (bayberry family) contains the bayberry, sweetgale, and sweet-fern species.[1]

Robert L. Wilbur (1994) recommended splitting Myrica (bayberry and sweetgale), moving most of the bayberry species to Morella and leaving sweetgale in Myrica. He also expressed doubt about whether the two eastern North American bayberry species, M. pensylvanica and M. caroliniensis, were distinct enough to be considered separate species.[2] In 2002, Wilbur made the recommendation that the two eastern North American bayberry species should be treated as a single species, Morella caroliniensis.[3]

Morella

edit
Some sources, including the New York Flora Atlas, treat northern and southern bayberry as a single species. Other sources treat them separately. If treated as two distinct species, only northern bayberry (Morella pensylvanica) is thought to be native or naturalized in New York. But, if treated as as single species, Morella caroliniensis would have priority as the species name.

  1. ↑ NYFA lists Morella pensylvanica as Morella caroliniensis (Mill.) Small, with Myrica pensylvanica as a synonym. However, the other sources listed here (except for Flora Novae Angliae @Go Botany) do not treat northern and southern bayberry as the same species. Flora of North America lists southern bayberry as Myrica heterophylla, and after discussing the minor differences between northern and southern bayberry, states "Whether these differences are sufficient to warrant the recognition of distinct species is yet to be satisfactorily resolved."

Family Juglandaceae

edit
The New York members of the Juglandaceae (walnut family) include about ten reported native walnut and hickory species, and a single non-native walnut species.[1] These trees are valuable both for their timber and nut production.
  1. ↑ Juglandaceae Troy Weldy & David Werier (2013) New York Flora Atlas. New York Flora Association, Albany, New York.

Subfamily Juglandoideae

edit
Both of the New York Juglandaceae tribes are placed in the Juglandoideae. Their fruits are similar in that they are composed of a nut surrounded by a fleshy outer covering so that they somewhat resemble a drupe such as a peach or plum.

Tribe Juglandeae

edit
The Juglandeae in New York consist of the relatively common native black walnut and butternut (or white walnut) trees.
Juglans
edit
Black walnut (Juglans nigra) may not be native to all parts of New York. It was once a dominant tree in the midwest and southeast, and was probably cultivated by Native Americans in parts of the state where it didn't occur naturally.

Most butternut (Juglans cinerea) trees in the state appear to have been infected by the butternut canker (the fungus Sirococcus clavigignenti-juglandacearum) . Some naturalized "English" and possibly "Japanese" walnut trees have also been found in the southeastern part of the state.

Tribe Caryeae

edit
Carya
edit
 
Carya cordiformis
North American hickories (Carya) are often divided into two groups: the true hickories (sect. Carya) and the pecan hickories (sect. Apocarya). Section Apocarya contains the pecan hickories, including pecan (Carya illinoinensis), water hickory (C. aquatica), and nutmeg hickory (C. myristiciformis). The wood of the trees in this section is generally considered to be a bit less dense and softer than that of the true hickories.[1] The only member of sect. Apocarya found in New York is bitternut hickory (Carya cordiformis). Section Carya contains the true hickories.

Recent molecular data does not strictly support using those two groups.[2]

Betula

edit
 
Betula papyrifera
Betula (ˈbech-ə-lə) in New York consists of about nine native species of birch trees, at least two native hybrids, and a single naturalized non-native species (though others have likely been planted). Here they are segregated into four subgenera:
  • Subg. Betulenta: B. alleghaniensis & B. lenta
  • Subg. Betula: B. populifolia, B. papyrifera, B. cordifolia, & B. pendula
  • Subg. Neurobetula: B. nigra
  • Subg. Chamaebetula: B. pumila, B. glandulosa, & B. minor
Betula subg. Betulenta
edit
 
Palustrine forest of hemlocks, sweet birches (Betula lenta), and yellow birches (Betula alleghaniensis) along Fall Creek, Monroe County, Pennsylvania.
Subgenus Betulenta contains the wintergreen-oil birches, which in New York consist of yellow and black birch. These contain a noticeable amount of methyl salicylate in their twig bark, giving the twigs a minty odor when broken.

Subfamily Coryloideae

edit
The Coryloideae subfamily of the birch family generally includes the hornbeam (Carpineae) and hazel (Coryleae) tribes.

Tribe Carpineae

edit
The Carpineae comprise the hornbeams (Carpinus) and hop-hornbeams (Ostrya). A single species of each is native to New York.
Ostrya
edit
 
Ostrya virginiana
American hophornbeam
The genus Ostyra is generally known as hop-hornbeam, or ironwood. Of the approximately nine Ostyra species worldwide, only the Eastern hop-hornbeam species is known to grow outside of cultivation in New York. Because of its small size, shade tolerance, low timber value, and high reproductive rate, hop-hornbeam is often considered to be an undesirable understory species in forests being used for commercial timber production.[1][2]

Carpinus caroliniana
American Hornbeam
The only species of hornbeam native in New York goes by the name American hornbeam, blue beech, or muscle-wood. It also goes by the name ironwood, but as that name is also commonly used for the related hop-hornbeam tree, perhaps it should be used for neither.
