The most interestingamong them were those corresponding to thenomina nuda from Brotherus published inMildbraed (1922) on material coming fromAnnobon. Happily, several specimens have beendetermined during recent revisions and theiractual names were written on the label.These nomina nuda have consecutively beencompiled both in the general African moss list(Schultze-Motel 1975, O’Shea 1997) and in thepreliminary checklist for Equatorial Guinea(Heras & Infante 1996).128After examination, as we supposed, these nominanuda corresponded to previously described taxa,but some of them still provide interestingfloristical and chorological data both for theRepublic of Equatorial Guinea and the Africancontinent.Revised nomina nuda from AnnobonThere are twelve nomina nuda from the AnnobonIsland in the Mildbraed (1922) paper. Touw(1976) stated that Thuidium annobonense wasThuidium gratum (P. Beauv.) Jaeg. and in thispaper we present the identity of eight additionalnames (Callicostella parvula, Calymperesannobonense, Calymperes subtenellum,Cyclodictyon annobonense, Leucophanesannobonense, Philonotis annobonensis,Porotrichum annobonense and Vesiculariaannobonensis). Unfortunately, in the BrotherusHerbarium of the University of Helsinki we couldnot find the specimens corresponding to the otherthree existing names: Distichophyllumannobonense, Mittenothamnium pallescens andSematophyllum annobonense.Callicostella parvula Broth. in Mildbraed, nomennudum = Callicostella constricta (C. Müll.)Kindb. (det.: W.R. Buck, 6.1998).“Afr. Occ., ins. Annobon, Gipfel der Sta. Mina,600 – 650 m, Nebelwald. J. Mildbraed 6706, 9/1911” (H-BR 0756326).Known from several African countries (O’Shea1997), mainly from West and Central Africa(Cameroon, Gabon, Central African Republic,Ivory Coast, Nigeria and Zaire) but also in EastAfrica (Tanzania, Madagascar and ComorosIslands). It was also recorded in Bioko.Calymperes annobonense Broth. in Mildbraed,nomen nudum = Calymperes erosum C. Müll.(det.: W.D. Reese, 1987).“Afr. Occ., ins. Annobon, 400 m, Polster anOelpalmen Stammen. J. Mildbraed 6692, 9/1911” (H-BR 0781038).Widespread species throughout many West,Central and East African countries (O’Shea1997). Recently collected in Bioko (Müller 1996)and the Continental Region of Equatorial Guinea(Infante & Heras 1998).Calymperes subtenellum Broth. in Mildbraed,nomen nudum = Calymperes palisotii Schwaegr.(det.: W.D. Reese, 1987).“Afr. Occ., ins. Annobon, trockener Waldoberhalb San Pedro, auf Stein, c. 100 m. J.Mildbraed 6755, 9/1911” (H-BR 0781039).This is also a well recorded moss in West, Centraland East African countries (O’Shea 1997). It is avery common species in the Continental Regionof Equatorial Guinea (Infante & Heras 1998).Cyclodictyon annobonense Broth. in Mildbraed,nomen nudum = Cyclodictyon vallis-gratiae (C.Müll.) O. Kuntze. (det.: F. Demaret, 1953).“Afr. Occ., ins. Annobon, Gipfel der Sta. Mina,600 - 650 , Nebelwald. J. Mildbraed 6705, 9/1911” (H-BR 1101040).It seems to be a rather spread species inSubsaharian Africa (O’Shea 1997). Recentlyfound in Bioko (Müller 1996) and the ContinentalRegion (Infante & Heras 1998).Leucophanes annobonense Broth. in Mildbraed,nomen nudum = Leucophanes unguiculatumMitt.. (det.: P. Heras, 4.1998).“Afr. Occ., ins. Annobon, 400 m, Quioveo, 500- 600 m. J. Mildbraed 6570, 9/1911” (H-BR2466011).An endemic species from West Africa (Salazar1993) only known from Nigeria and PrincipeIsland (O’Shea 1997). New record for theEquatorial Guinean bryoflora.Philonotis annobonensis Broth. in Mildbraed,nomen nudum = Philonotis uncinata (Schwaegr.)Brid. var. glaucescens (Hsch.) Florsch. (det.: D.Griffin III, 9.11.1998)“Afr. Occ., ins. Annobon, 400 m, Vorland,Bachbett auf Lava. J. Mildbraed 6689, 9/1911”(H-BR 3087045).Dana Griffin III (in litt.) noted that the specimenmatches with this pantropical and lowland -medium elevation species, common in theNeotropics. However it has not been recorded inthe Subsaharian Africa moss literature (O’Shea1997).Porotrichum annobonense Broth. in Mildbraed,129nomen nudum = Porotrichum elongatum (Welw.& Duby) Gepp (det.: J.L. De Sloover, 1982).“Afr. Occ., ins. Annobon, Aufsteig zum Quioveo,400 m. J. Mildbraed 6683, 9/1911” (H-BR3376022).Very widespread species in Subsaharian Africa(O’Shea 1997). It occurs also frequently inEquatorial Guinea, both in Annobon and BiokoIslands and the Continental Region (Heras &Infante 1996, Infante & Heras 1998).Vesicularia annobonensis Broth. in Mildbraed,nomen nudum = Vesicularia strephomischos(Welw. & Duby) Broth. (det.: W.R. Buck,6.1998).“Afr. Occ., ins. Annobon, Bacbett bei Santa Cruz,über feuchten Steinen. J. Mildbraed 6597, 9/1911” (H-BR 4342027).In Africa this species is only recorded fromAngola (O’Shea 1997, Kis 1985). New recordfor the Republic of Equatorial Guinea.AcknowledgementsWe are very grateful to Drs. W.R. Buck and D. GriffinIII for identifying the Callicostella, Vesicularia andPhilonotis material. We want also to express ourgratitude to Dr. S. Piippo for the loan of the Annobonspecimens in the H-BR Herbarium and Dr. T.
