Lycianthes ceratocalycia (Donn.Sm.) Bitter (1919: 498)

≡ Brachistus ceratocalycius Donnell Smith (1909: 297) .

Type (lectotype, designated here):— GUATEMALA. Alta Vera Paz: Bergwald bei Cobán, 1600 m, Jan 1908, von Tuerckheim II 2060 (US barcode 00624002!, isolectotypes BM barcode 000514916( BM) [digital photo!], E barcode E00190707 [digital photo!], F barcode 0072757F [digital photo!], M barcode M-0171534 [digital photo!], NY barcode 00007074 [digital photo!], US barcode 00624001!; image of the lectotype is available at https://collections.nmnh.si.edu/search/botany/) .

Nomenclatural notes:— Donnell Smith (1909) cited one gathering in the protologue: von Tuerckheim II 2060 with no herbarium specified. We traced several specimens in the herbaria BM, E, F, M, NY, and US belonging to the cited gathering: Tuerckheim II 2060 ( US barcode 00624002), BM barcode 000514916( BM), E barcode E00190707, F barcode 0072757F, M barcode M-0171534, NY barcode 00007074, US barcode 00624001). These specimens completely agree with the protologue and with the current application of the name ( Gentry & Standley 1974) and can be safely considered as original material (Art. 9.3. of the ICN, McNeill et al. 2012). One of the von Tuerckheim II 2060 specimens at US ( US No. 1335153 [barcode 00624002]) is selected here as the lectotype for the name Brachistus ceratocalycius .

Taxonomic notes:— Lycianthes ceratocalycia is an herb to shrub with purple, stellate corollas that occurs in southern Mexico and Guatemala. It was under-collected until quite recently and mainly known from the type specimens. One of its most distinctive characters is a rough, scurfy texture on the young branches formed by horizontal indentations.
