  “Very closely allied to N. purpurata” [N. kotschyi var. purpurata] according toFl. Trop. E. Afr., Orchid. 2: 275, but “further material is needed before an assessment of its relationships to N. purpurata and N. kotschyi can be made”. Taxonomic status uncertain: N. similis was considered a synonym of N. kotschyi by Pettersson, 1991: 60. The same author commented on N. similis in Nord. J. Bot. 9: 491, 1990: The original type of Stolz 2347 in B was destroyed in World War II. Isotypes are present in BM, K, PRE. The K sheet is the only one having a leaf in addition to the flowers. But Schlechter (Bot. Jahrb. Syst. 53: 554, 1915) stated that he had seen no leaves. And the leaf is very similar to that of N. shirensis. Stolz 2347 was collected in the same place and on the same day as Stolz 2348 (= N. shirensis). The flowers of N. shirensis were then ± over, while those of N. similis were in best anthesis. Therefore it is likely that the leaf belonged to N. shirensis. However, it is possible that the leaf was added later, on a second visit to the same place. A mistake during mounting of the herbarium sheet at K cannot be excluded. The K sheet has 4 inflorescences and an original Stolz label; Pettersson selected this sheet as a lectotype, excl. the leaf.
