Chapter 7: Linnaean Plant Names and their Types (part H) Author Jarvis, Charlie Department of Botany, Natural History Museum, Cromwell Road, London, UK text 2007 Linnaean Society of London in association with the Natural History Museum London Order out of Chaos. Linnaean Plant Types and their Types 557 585 book chapter https://doi.org/10.5281/zenodo.291971 978-0-9506207-7-0 291971 Houstonia purpurea Linnaeus , Species Plantarum 1 : 105. 1753 . "Habitat in Virginia." RCN: 858. Lectotype (Reveal & al. in Huntia 7: 234. 1987): Clayton 63 [ "506" ] (BM-000042707). Current name: Houstonia purpurea L. ( Rubiaceae ). Note: Terrell (in Rhodora 61: 168. 1959) evidently regarded material on 128.2 (LINN) as the type, but this collection was a later addition to the herbarium, and ineligible. Reveal & al. designated what is evidently Clayton 63 (BM) as lectotype , despite describing it as Clayton 506. Subsequently, Terrell (in Syst. Bot. Monogr. 48: 50. 1996) has rejected their choice in favour of Clayton 63 , but it seems clear that both are talking about the same sheet and there has merely been confusion over labelling.
