Abstract This paper reports the results of an inventory of the vascular plants at the Hugo Wildlife Management Area in southeastern Oklahoma. A total of 573 specific and interspecific taxa of vascular plants in 359 genera and 113 families were collected. The most commonly collected were of the families Poaceae (75), Asteraceae (76), Fabaceae (40), and Cyperaceae (38). One hundred sixty-four species were annuals or biennials, and 409 were perennials. Ninety-seven species of woody plants were present. Fifty-one exotic species were collected representing 9% of the flora. Fourteen species tracked by the Oklahoma Natural Heritage Inventory were found. This study reports 256 species previously not documented in Choctaw County.

Additions to the Vascular Flora of the Red Slough Wildlife Management Area, McCurtain County, Oklahoma

ABSTRACT  The Red Slough Wildlife Management Area (7,800 ha) is located on the West Gulf Coastal Plain in southeastern Oklahoma. The inventory was motivated by land acquisitions and is intended to augment a 1999 inventory. We report an additional 202 taxa of vascular plants, with 186 species, 16 infraspecific taxa, 158 genera, and 68 families. This is a 62% increase in the number of taxa previously listed for the site. The largest families were the Poaceae (with 35 taxa), Asteraceae (20 taxa), and Fabaceae (18 taxa). Thirty-one nonnative taxa and 19 taxa tracked by the Oklahoma Natural Heritage Inventory were encountered.

The Vascular Flora of the Little River National Wildlife Refuge, McCurtain County, Oklahoma

ABSTRACT   The Little River National Wildlife Refuge (6,070 ha) is located on the west Gulf Coastal Plain in southeastern Oklahoma, a region of high plant diversity for the state. An inventory of the refuge yielded 708 taxa of vascular plants in 688 species, 410 genera, and 128 families. The largest families were the Asteraceae (n = 88 taxa), Poaceae (n = 76), Cyperaceae (n = 49), and Fabaceae (n = 44). Sixty-seven nonnative taxa were collected, representing 9.5% of the flora. Sixty-two taxa were present that are tracked by the Oklahoma Natural Heritage Inventory, including the Oklahoma endemic, Leavenworthia aurea var. aurea. In addition, we report the first Oklahoma collection of Polygonum glabrum.
