Could this possibly be Dietes grandiflora? According to San Marcos Growers, "This plant has been long grown as Dietes iridioides or D. vegeta in the nursery trade but is rightlyfully Dietes grandiflora. This can be determined by examing the flower tepals and style arms; Dietes grandiflora has brown markings on the inner tepals and dark violet style arms where Dietes iridioides lacks markings on the tepals other than the yellow spots on the outer tepals and has pale violet style arms." - ref:
