Family Juncaceae edit

The rush family (Juncaceae) in New York consists of the rushes (Juncus) and the woodrushes (Luzula).

Luzula edit

The genus Luzula (woodrush). The classification used here for Luzula the one used by the Database of Vascular Plants of Canada (VASCAN), which cites Kirschner et al. (2002)[1] for subgenera and section assignments.

Luzula subg. Luzula edit

Luzula subg. Luzula sect. Anthelaea edit
 
Luzula luzuloides
Luzula sect. Anthelaea Griseb. (1846) contains about ten species, originating primarily in southwestern Europe, the Alps, and Macaronesia. Of these, only Luzula luzuloides has been reported outside of cultivation in New York.

Luzula subg. Luzula sect. Diprophyllatae edit
 
Luzula parviflora
Luzula sect. Diprophyllatae Satake (1938) contains about 12 species worldwide. Only one of those, Luzula parviflora, has been collected in New York. The New York Flora Atlas currently lists this taxon only at the species level, naming ssp. melanocarpa as a synonym. But a number of recent sources, including Kirschner (2002), list fastigiata, melanocarpa and parviflora as acceped subspecies of L. parviflora. Of these, only ssp. melanocarpa has a range that includes New York.

Juncus articulatus
Juncus sect. Ozophyllum Dumort. (1827), the largest Juncus section, with about 84 species worldwide,[1] is well represented in New York, with about 15 mostly-native species. Four of these are considered endangered in the state. One member, Juncus diffusissimus, is considered to be a native to the south-central United States, and has only recently been discovered on Long Island.[2]
