Trillium texanum, the Texas trillium or Texas wakerobin, is a species of flowering plant in the family Melanthiaceae. It is found in east Texas, extreme southwestern Arkansas, and extreme northwestern Louisiana. Due to its limited range, it is designated as a vulnerable species.
Trillium texanum is a perennial herbaceous plant that flowers from March to early mid-April, with white flower petals. [5]
Trillium texanum was first described by Samuel Botsford Buckley in 1861. [3] Its type specimen was collected in Panola County, Texas, [6] but that specimen is now lost. [7] The specific epithet texanum refers to the U.S. state of Texas, its primary location.
As of April 2023 [update], the name Trillium texanum Buckley is widely recognized, [1] [2] [4] [8] but a few authorities regard it as a variety of Trillium pusillum, either T. pusillum var. texanum or T. pusillum var. pusillum. [9] [10] The taxon is a member of the Catesbaei group ( Trillium subgen. Delostylis), a group of pedicellate-flowered trilliums that includes Trillium catesbaei.
Trillium texanum is found primarily in east Texas, [11] hence the common name Texas trillium. It also occurs in extreme southwestern Arkansas and extreme northwestern Louisiana. [1] It typically grows in forested wetland habitat. [5]
As of April 2023 [update], the global conservation status of Trillium texanum is listed as vulnerable by both NatureServe and IUCN. [1] [2] It is critically imperiled in both Arkansas and Louisiana. [12] It is under review by the U.S. Fish & Wildlife Service. [13]
