Notes. – The type specimen of Ixia campanulata is in the Cape herbarium in G-PREL. MERRILL (1938: 327) did not recognise it as Houttuyn’s. BROWN (1929: 133) and LEWIS (1962: 126) recognised this collection as the holotype, whereas GOLDBLATT & MANNING (2016: 185) correctly accepted Brown’s mention as an implicit lectotypification. Four collections of possibly different gatherings are present in UPS-THUNB for Ixia aristata (UPS- THUNB n° 917, n° 918, n° 919 and n° 920). The better-preserved specimen is designated here as the lectotype.

Several other collections of Ixia L. are in Houttuyn’s Cape herbarium: I. maculata L. (G-PREL [G008181221]), I. monadelpha D. Delaroche (G-PREL [G008181217, G008181218]), I. polystachya L. (G-PREL [G008181219]), and I. scillaris L. (G-PREL [G00818120]). Two further specimens identified by Houttuyn as I. grandiflora D. Delaroche are now recognised in Sparaxis Ker Gawl. as S. grandiflora (D. Delaroche) Ker Gawl. (G-PREL [G00818122, G00818123]).
