Ind.: 233. 1768. Lectotypus (designated by STEENIS, 1934: 288 ): INDONESIA . Java : s.d., Anon . s.n. ( G-PREL [ G00348837 ]!). = Plectranthus scutellarioides (L.) R. Br. , Prodr.: 506. 1810 . ≡ Ocimum scutellarioides L. , Sp. Pl. ed. 2: 834. 1763. (Lamiaceae) Notes. – In the protologue, BURMAN (1768: 233) simply referred to an illustration ( PETIVER, 1712: 38 , tab. 14, fig. 2) as (unnamed) variety β . He did not mention any collector, merely “ Habitat in Java ” as locality. But his comment about the variety β (“[...] cum javanica sit ovata [...]”), a comparison between Petiver’s plate and an actual Javan specimen, may be regarded as implicit specimen citation. Fig. 4. – Lectotype of Polypodium adianthoides Burm. f. in G-PREL. Asingle specimen of original material is extant in G-PREL [G00348837]: it bears a reference to Petiver’s illustration and the name of the new species, both from N.L. Burman’s hand, as well as a few notes by John Briquet (1870 – 1931), former curator of the Delessert Herbarium (“ Java / non filix / non Petiver ” in front of the reference to Petiver’s illustration). MERRILL (1921: 337) treated Polypodium ovatum as of doubtful status. This name refers indeed to a commonly cultivated form of Plectranthus scutellarioides ( Lamiaceae ) , as correctly identified by STEENIS (1934: 288) , who also designated the above specimen (seen as photograph!) as “actual type ”. This implicit lectotypification is accepted here.
