Trillium sulcatum Patrick View in CoL View at ENA , Brittonia 36: 27–35, f. 1–5. 1984.

Type:— USA. Tennessee: Grundy Co., rich bouldery woods at base of N-facing slope near Deer Lick Falls in Layne Cove , elev. ca. 420 m, western escarpment Cumberland Plateau, 2 km due N of Monteagle , 21 Apr 1980, Patrick, Perkins & Horn 1122 (holotype: TENN!; isotypes: BH, DUKE10000089 About DUKE digital image!, GH00030175 digital image!, MO-104974!, NCU00000629 About NCU digital image!, NY00319900 digital image!, UNA, US 00406395 digital image!) .

Heterotypic synonyms: Trillium erectum var. sulcatum Barksdale, J. Elisha Mitchell Sci. Soc. View in CoL 54: 280–281. 1938. Type:— USA. North Carolina: Surry Co., in deep woods near Roaring Gap, 27 Apr 1937, Lyons s.n. (holotype: NCU00000625 digital image!; isotypes, NCU00000621 digital image!, NCU00000622 digital image!, NCU00000623 digital image!, NCU00000624 digital image!, NCU00000626 digital image!).

Note:— This name was published without a Latin diagnosis and is thus invalid. The date of collection is given as “1934” on plants.jstor. org, but the specimen labels read 1937.

Trillium sulcatum f. albolutescens T.S.Patrick View in CoL , Brittonia 36: 30. 1984. Type:— USA. North Carolina: Ashe Co.; rich shady western slopes of “The Peak,” in western part of Ashe County, 16 May 1950, Harper 4167 (holotype: MO-104973!; isotypes: GH00030176 digital image!, NY00319901 digital image!, US 00406185 digital image!).

Notes:— This species is similar to T. erectum but occurs mostly occurs to the west, largely on the Cumberland Plateau in Kentucky, Tennessee and adjacent Alabama. The two are sympatric in a small portion of their distributions in eastern Kentucky, north-eastern Tennessee, south-western Virginia, and north-western North Carolina along the Blue Ridge escarpment of the Southern Appalachians. In some cases, the two species are hard to separate based and may be better regarded as a single variable species with a broad range of variation and similarities in floral fragrance and habitat preferences. However, in cultivation, lower-elevation T. sulcatum is a better garden plant and more vigorous. In the Ridge and Valley of Tennessee, white-flowered forms in uniform populations have been misidentified as T. flexipes , but these forms have dark ovaries and the wet-dog floral fragrance of the typical forms (AF pers. obs.).
