Cacalia porophyllum Linnaeus View in CoL , Species Plantarum 2: 834. 1753.

"Habitat in America." RCN: 6036.

Type not designated.

Original material: Herb. Linn. No. 976.9 ( LINN); Herb. Linn. No. 976.8 ( LINN); [icon] in Morison, Pl. Hist. Univ. 3: 106, s. 7, t. 17, f. 7. 1699; [icon] in Plukenet, Phytographia: t. 161, f. 1. 1692; Almag. Bot.: 100. 1696 - Typotype: Herb. Sloane 95: 166 ( BM-SL) .

Current name: Porophyllum ruderale (Jacq.) Cass. View in CoL ( Asteraceae ).

Note: Keil (in Ann. Missouri Bot. Gard. 62: 1234. 1975) indicated either Herb. Linn. 976.8 or 976.9 (LINN), neither of which he had seen, as “Type”. As these two collections are evidently not part of a single gathering, Art. 9.15 does not apply and the name seems as yet untypified.
