Comments on the distribution of \u3ci\u3eBotrychium lunarioides\u3c/i\u3e (Ophioglossaceae) in Texas

Botrychium lunarioides (Michx.) Sw. (Ophioglossaceae) is now known to be widespread and abundant throughout the eastern portion of Texas. In 1996, Do, et al. reported ten additional county records in the central portion of the Post Oak Savannah of Texas, thereby extending the known distribution of the species up to 273 km to the west. Additional field studies during 1996 have yielded nineteen new county records for the species in Texas. These new reports are primarily from the Post Oak Savannah, Pineywoods, and Blackland Prairies of northeast Texas and from the southern portion of the Post Oak Savannah. The most notable occurrence of the species is at Lake Bastrop State Recreation Area, Bastrop County, about 45 km ESE of Austin, which extends both the western and southern known limits of the species

New County Records of \u3ci\u3eBotrychium lunarioides\u3c/i\u3e in Texas.

Recent collections of B. lunarioides in east-central Texas indicate that the species is more widespread within the state (Fig. 1). Other than for Navarro County, the new records are in the Post Oak Savannah Region of the state, with the Navarro County location classified as being within the Blackland Prairie Region or in part of an extension of the Post Oak Woods/Forest in the Blackland Prairie Region. All specimens previously cited by Thomas (1979) and Thomas et al. (1981) were from the eastern part of the Pineywoods Region. The San Augustine site is about 32 km from the state line of central Louisiana, whereas the Cass County record is approximately the same distance from southwestern Arkansas. The new locations extend the known distribution of the species from 161 to 273 km to the west. This may indicate, especially when the Oklahoma distribution is considered, that the species is to be expected in similar habitats throughout the intervening areas of the Pineywoods and Post Oak Savannah Regions of Texas
