Notes
Hallier’s treatment is possibly to be preferred since lax-flowered specimens are very close to I. ficifolia Lindl. Species 23–26 form a complex and may be a singlespecies but then the variation would be very wide and cover some easily distinguished if somewhat unstable types. Genetical work is clearly indicated. Dammer gives the corolla-length of his species as 3.9 cm. but the preserved isotype unfortunately has no corollas.
