(2814) Proposal to conserve the name Leea macrophylla against Aralia lappifolia ( Vitaceae )

(2814) Leea macrophylla Roxb. ex Hornem., Hort. Bot. Hafn.: 231. 1813 [Angiosp.: Vit.], nom. cons. prop. Typus: India, Serampore (C barcode C10020284). (=) Aralia lappifolia Retz., Observ. 6: 27. Jul–Nov 1791, rej. Lectotypus (hic designatus): “Aralia Lappaefolia n.” (LD 1754684). Noltie (in Taxon 62: 1340. 2013) successfully proposed the outright rejection of name Aquilicia samudraca Jones Asiat. Res. 4: 265. 1795) as it threatened Hornem. (Hort. 1813), a well-known species from South and South-East Asia. This proposal similarly seeks to maintain nomenclatural stability by another earlier synonym Retzius (Observ. 1791) described (as ‘lappaefolia’) based on specimens that he received Johann Koenig in India. Fischer Bull. Misc. Inform. Kew 1932: 53. 1932) noted presence two sheets Lund herbarium represented original material for lappifolia. tentatively identified plant macrophylla. In our opinion this is correct identification specimens. We here select specimen with better-developed inflorescence lectotype name. Ridsdale Blumea 22: 85. 1974), last complete revision Leea, L. was rather variable vegetatively, particularly terms stature at maturity leaflet number, but floral morphology more consistent. It has been suggested should be split up (Molina & al. J. Linn. Soc. 171: 354. 2013). Therefore, type available possible someone splitting “Leea complex” future may find desirable use “lappifolia” epithet, conserve against lappifolia, than reject latter outright, preventing way, being displaced (l.c.) referred “in Herb. Roxburgh s.n., (C)”. There sheet Copenhagen labelled back Serampore”, which we take one Ridsdale, though handwriting not Roxburgh's. Possibly later collection, Ridsdale's effective lectotypification neotypification. However, no other available, typification accepted us. reported acceptance all recent floras across its range. also substantial body research publications, notably medicine, ethnobotany chemistry, employing (nearly 500 entries 2016 onwards Google Scholar). therefore propose much-used conserved scarcely since publication.
