### Subtribe Rudbeckiinae

* Rudbeckia is a North American genus and very commomly found in New York, but only a few of its taxa are considered to be truly native to the state. Rudbeckia is here separated into the sections described by the Flora of North America.
* According to the New York Flora Atlas, among the Rudbeckia species, only R. laciniata var. laciniata is fully native to New York. However, R. triloba var. triloba is thought to be native in an unspecified part of the state, and introduced elsewhere in New York.

##### Xanthium

* Although the New York Flora Atlas and the USDA-NRCS Plants database list three varieties of Xanthium strumarium, the Flora of North America does not recognize any varieties for this species, finding that their differences "mostly involved subtle differences in the burs." The other sources used here follow that circumscription.
