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]).
