Jarvis, Charlie, 2007, Chapter 7: Linnaean Plant Names and their Types (part G), Order out of Chaos. Linnaean Plant Types and their Types, London: Linnaean Society of London in association with the Natural History Museum, pp. 529-556 : 529

Gnaphalium obtusifolium Linnaeus , Species Plantarum 2: 851. 1753.

"Habitat in Virginia, Pensylvania." RCN: 6183.

Lectotype (Reveal in Jarvis & Turland in Taxon 47: 362. 1998): Kalm, Herb. Linn. No. 989.64 ( LINN) .

Current name: Pseudognaphalium obtusifolium (L.) Hilliard & B.L. Burtt ( Asteraceae ).

Note: Blake (in Rhodora 20: 72. 1918) discussed this name, as did Hilliard & Burtt (in Bot. J. Linn. Soc. 82: 205. 1981), who treated 989.63 and 989.64 (LINN) as syntypes. As these collections are neither syntypes nor part of a single gathering, Art. 9.15 does not apply. Reveal’s appears to be the first explicit type choice.
