Distribution:— Northeastern, southeastern and southern Brazil: Bahia, Espírito Santo, Rio de Janeiro, S"o Paulo, Paraná, Santa Catarina. TDWG code: 84 BZE-BA BZL-ES BZL-RJ BZL-SP BZS-PR BZS-SC.

Taxonomic notes:— Many different interpretations were given to the accessory lip structures in species of Paradisanthus   . Originally described as unguiculate, erect lateral lobes with a sac between them (Reichenbach 1852b), Pupulin et al. (2009b) described them as unguiculate or sessile with an antrorse callus. We agree with Hoehne (1953), who described it as unguiculate without lateral lobes, but we characterize the callus as semi-conic, retrorse with irregular margins.

Cogniaux (1898b), Hoehne (1953) and Schlechter (1918b) distinguished the species of Paradisanthus   based on leaf width, lip shape, presence of hair on the callus, and callus margin. Pabst & Dungs (1977) apparently also followed the same circumscriptions. However, after examination of the nomenclatural types and many specimens, it 28 • Phytotaxa 238 (1) © 2015 Magnolia Press MENEGUZZO ET AL.

was observed that these authors possibly based their concepts on misinterpreted structures repeated in the literature with few specimens personally examined. Variation in leaf width and lip shape and size are not useful for identifying natural taxa because transitional forms are often found. In addition to that, a hairy inner lip surface is present in all specimens.

The northernmost distribution of species is Bahia, where flowers of most continental (Chapada Diamantina) and coastal specimens (from Valença to Una) are described in herbarium specimens as white to pinkish. However, flowers of a few scattered specimens from coastal regions also are reported to be green. Specimens south of Una always described as green. At this time, we were not able to gather enough field information about distribution of colour patterns within and between populations from Bahia to segregate morphotypes as different taxa. In addition to colour, there is no obvious morphological discontinuity between collections. The selected lectotype of P. bahiensis   has white flowers in concordance with the protologue, whereas all other names were described as green.

Nomenclatural note:— The type of Paradisanthus bahiensis   was not found at W-R. In this herbarium, there are three sheets under the same name with original Reichenbach identifications (W-R 3325, 38097, 38098, see additional material examined). There is also a sheet with an original identification by the same, but under P. mosenii   (W-R 38118), mounted with an illustration referred as a Kramer specimen, the same type collector of P. bahiensis   (W-R 38118). On sheet W-R 38097 there is an illustration by Reichenbach that is dated September 1880, so this illustration cannot be considered part of the lectotype because it is dated after the protologue. W-R 38098 is to be disregarded because it also postdates the protologue. There are fragments of P. mosenii   and pseudobulbs and rhizome of an unidentifiable orchid. Due to the impossibility of identifying original material, we were unable to choose a lectotype among these three sheets, so we opted to choose a neotype that is unrelated to them.

It was observed in original of Paradisanthus mosenii   in Mosén’s herbarium at S that specimen numbers refer to a sequence of genera and species, not collection numbers. Thus, different specimens could be placed under the same number. The lectotype of P. mosenii   was chosen among distributed duplicates under the number cited in the protologue. It is not possible to confirm that specimen Mosén 3486 (P 447841) is a nomenclatural type because there is no information of its provenance or date. It was obtained from the Glaziou herbarium, identified with unknown handwriting, which was not that of Mosén, Barbosa Rodrigues or Glaziou.

The holotype of Koellensteinia espiritosantensis   was not found at MBML. In the spirit collection there we found a well-preserved specimen identical to the illustration in the protologue, for which morphology agrees with the number and shape of pseudobulbs and leaves and inflorescence branching. There is a new label made after the floods that destroyed part of the herbarium in 2000: “10/03/1954; Koellensteinia espiritosantensis Ruschi   ”. Ruschi did not always cite the herbarium in which he deposited his specimens, and there are no data in the spirit specimen that allows it to be inferred as the holotype. Probably there was a mistake when transcribing and distributing the new labels among the broken jars. No record book was found to crosslink the spirit specimen data and protologue. Because of this, we choose the original illustration as lectotype.

For first time Paradisanthus mosenii   var. virens   is registered as a name in scheda.
