Order Juglandales[edit]

The Juglandales, as used here, includes the beech family (oak, chestnut, and beech), the bayberry family (sweet-fern and bayberry), the walnut family (walnut and hickory), and the birch family (alder, birch, hornbeam, and hazlenut). These plants primary take the form of trees. They are often placed in the Fagales.

Quercus sect. Quercus[edit]

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. 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[edit]

Genus Fagus[edit]

The American beech, Fagus grandifolia, is a widespread hardwood tree in New York, and historically associated with Acer saccharum 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.[2] 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.

  2. 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 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.

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. Butternut canker (the fungus Sirococcus clavigignenti-juglandacearum) appears to have infected most butternut trees in the state. Some naturalized "English" and possibly "Japanese" walnut trees have also been found in the southeastern part of the state.
