Introduction
Moussonia Regel (Gesneriaceae: Gesnerioideae: Gloxiniinae) is a neotropical genus comprising 23 species, up from 11 recognized by Wiehler (1975) in his re-establishment of the genus, and about 10 according to Skog (1979). The genus is distributed from Mexico to Panama, except for Belize.
A revision of Moussonia was published as an e-book by the first author (Ramírez-Roa, 2017), and consisted of 3 main contributions: 1) a complete taxonomic survey of the genus; 2) segregation of the heterotypic synonyms included in Moussonia elegans Decne. complex, and 3) presentation of 5 new species; thereby adding 11 species to those already included in Moussonia as circumscribed by Wiehler (1975) when he separated the genus from Kohleria Regel. From the synonyms in M. elegans, 5 were again considered as species to be accepted, M. collina (Brandegee) Ram.-Roa, M. costaricensis Klotzsch ex Oerst., M. jaliscana (S.Watson) D.L.Denham ex Ram.-Roa, M. papillosa Oerst. ex Hanst, and M. pedunculata (Brandegee) Ram.-Roa. Moussonia formosa Van Houtte ex Regel was transferred to the synonymy of Moussonia deppeana (Schltdl. & Cham.) Klotzsch ex Hanst., and 2 varieties were given new status as species: M. pendula (C.V.Morton) Ram.-Roa, formerly Kohleria papillosa (Oerst. ex Hanst.) Fritsch var. pendula C.V.Morton, and M. solitaria (C.V.Morton) Ram.-Roa, formerly Kohleria papillosa var. solitaria C.V.Morton.
The names of the new species and the new combination in Moussonia (Ramírez-Roa, 2017) were published according to Article 29.1 of the Shenzhen Code (Turland et al., 2018). However, one of the revived names, M. pedunculata, and one of the stat. nov. species, M. pendula, require modifications to be validly published.
Materials and methods
Following Article 30.4 of the Shenzhen Code (Turland et al., 2018), the modifications are presented here to make the species’ names effectively published.
Results
First modification
Moussonia pendula is a name given new status from Kohleria papillosa var. pendula for a species endemic to the state of Jalisco in Mexico. A single gathering was designated by Morton as type, E.T. Hooper s.n., however 2 specimens were indicated, one in MICH and another in US, with neither specimen selected by Morton as holotype (Ramírez-Roa, 2017). Taking into consideration Article 9.6, example 5 and Article 40.2, note 1 of the Shenzhen Code (Turland et al., 2018), these 2 specimens should be considered syntypes. Here, the specimen at MICH is designated as lectotype:
Moussonia pendula (C.V.Morton) Ram.-Roa, comb. et stat. nov. ≡ Kohleria papillosa (Oerst. ex Hanst.) Fritsch var. pendula C.V.Morton, Baileya 15: 72-73. 1967. Type: Mexico. Jalisco: 15-20 mi. SE of Autlán, Sierra de Manantlán, on the “bajada” S and W of the divide between Aserradero San Miguel Uno and Durazno, at ca. 1,700 m., on steep W-facing slopes in pine forest, March 2, 1953, E.T. Hooper s.n. (lectotype here designated: MICH!; isolectotype: US!).
Second modification
The name Moussonia pedunculata, is based on Kohleria pedunculata Brandegee from Chiapas in Mexico and Guatemala. Brandegee typified the species on a specimen at UC, C.A. Purpus 6664. Duplicates of the Purpus number exist in several herbaria, but all the sheets are either mixed collections with other species of Moussonia, particularly M. tacanaensis Ram.-Roa, a new species included in the revision (Ramírez-Roa, 2017), or not Moussonia pedunculata at all. For example, the specimen of Purpus 6664 at MO is wholly M. tacanaensis, the specimen at UC is partly M. skutchii (C.V. Morton & D.N. Gibson) Wiehler, and the other specimens of Purpus 6664 are mixed M. pedunculata and M. tacanaensis. The first author realized the problem of the mixed collections, but unfortunately selected a completely different collection as lectotype, which does not comply with Article 9.14 of the Shenzhen Code (Turland et al., 2018), therefore the correction is made here.
