The botanical legacy of Martinus Houttuyn (1720 - 1798) in Geneva Author Wijnands, Dirk Onno Author Heniger, Johannes Author Veldkamp, Jan Frederik Author Fumeaux, Nicolas Author Callmander, Martin W. text Candollea 2017 2017-05-12 72 1 155 198 journal article 20627 10.15553/c2017v721a11 ae864518-b1d7-49da-85dc-905b1a4e6809 2235-3658 5721887 95. Renealmia capensis Houtt., Nat. Hist. II(8): Aanwyz. Plaat. [2], 335, tab. 47, fig. 1. 1777. ≡ Villarsia capensis (Houtt.) Merr. in J. Arnold Arbor. 19: 360. 1938. Lectotypus (designated here by Veldkamp & Callmander): SOUTH AFRICA : Cape , Thunberg s.n. ( G-PREL [ G00074336 ]!; isolecto- : G-PREL [ G00818091 , G00818092 ]!, UPS-THUNB n° 4228 image seen). = Menyanthes capensis Thunb., Prodr. Pl. Cap. : 34. 1794 . Typus: SOUTH AFRICA : Cape , Thunberg s.n. ( holo- : UPS-THUNB n° 4228 image seen; iso- : G-PREL [ G00074336 , G00818091 , G00818092 ]!). Notes . – Original material of Renealmia capensis in Houttuyn’s Cape herbarium is designated here as the lectotype . It was very likely collected by Thunberg and also represents a duplicate of the type of the later name Menyanthes capensis Thunb. Two further specimens in the Burman herbarium in G-PREL were annotated by Thunberg as Menyanthes capensis and represent original material of both Houttuyn’s and Thunberg’s names. Menyanthes ovata L. f. (LINNAEUS f., 1782: 133) is also based on the same Thunberg collection at UPS-THUNB, but this name is superfluous, as well as the combination by VENTENAT (1803 - 1808: sub tab. 9): Villarsia ovata (L. f.) Vent. ( CALLMANDER et al., 2017 ). The generic Renealmia Houtt. was published by Houttuyn in 1777 (Nat. Hist. II(8): 335). Houttuyn noted “A new genus ... which I ... baptise with the name now available”. Up to the beginning of the 19th century botanists often regarded that a name placed in synonymy was then available for another use, a practice that is no longer allowed. The generic name Renealmia had previously been validated by LINNAEUS (1753: 286). Both are nom. rej. [against the nom. cons. of LINNAEUS f. (1782: 7)].
