Holub & Pouzar is lectotypified from Wollaston's specimen of D. affinis (Lowe) Fras.-Jenk. at MANCH, which maintains the stability of the nomenclature of the group. INTRODUCTION Dryopteris pseudomas (Woll.) Holub & Pouzar was raised by Holub to provide a name for the European D. affinis (Lowe) Fras.-Jenk. group, sens. Jat., and following the subdivision of the group as a critical complex, was subsequently applied by him to what is now called D. borreri Newm. However Wollaston also intended his name to apply to what is now the whole D. affinis aggregate and had no intention to confine it to D. borreri. His description emphasised the scaly, truncate-pinnuled, glossy nature of the plant and would obviously be most aptly applied to what is now D. affinis. But in fact his original specimen, marked by him as type, contains both species, so could be lectotypified in either sense. However the most obvious and characteristic morphology, as emphasisised in Wollaston's description, is that of the larger, left hand and main specimen on the sheet, which is a specimen of D. affinis, and is therefore selected here as lectotype. The small right-hand specimen is a compact and scaly D. borreri. LECTOTYPIFICATION Lastrea pseudomas Wollaston, Phytologist, n.s. [ser. 2] 1: 171-172 (1855). Dryopteris pseudomas (Wollaston) Holub & Pouzar, in Holub, Fol. Geobot. Phytotax. (Praha) 2: 329 332 (1967). Lectotype of L. pseudomas, designated here: Britain, England: "Lastrea pseudo-mas (Wol.) Type. Geo. B. Wollaston [G.B. Wollaston scripsit]. Nat. order 93, no 1793 C. Lastrea lix-mas (Presl) var. paleacea (Moore). Loc.-, Coll. George B. Wollaston, Date July 1884. Herbarium Walter W. Reeves bbenned label of Reeves]. Herbarium Sr Museum. [With lectotype labels from H.V. Corley in 1972 [ined.] and C.R. Fraser-Jenkins in 1979 and 1981]." (MANCH!). Left hand specimen only, which fits Wollaston's protologue descriptions (Wollaston 1855 and see also 1863 and 1915 and Wollaston's description in Moore 1855) much better than does D. borreri. The date of July 1884 is almost certainly, and is presumed here to be the date of acquisition Reeves, filled in by him on his herbarium label, printed with the categories, 'Loc.’, 'Dat etc., rather than the date of actual collection by Wollaston, whose own label oats that this is original (pre 1855) material and can therefore be chosen as lectotype rather than neotype. Other Reeves specimens in MANCH collected by him (sometimes with others) have a full date (including day) and locality given, unlike the present one, and another specimen from Wollaston of D. oreades, labelled var. abbreviatum, likewise has the same date of July 1884 and no locality. Manchester is where Wollaston's herbarium was sent (via Reeves) and there exists no other pre 1855 Wollaston material labelled as 285 FERN GAZ. 18(6): 284-285. 2009 representing L. pseudo-mas at MANCH or at KEW (in Moore's herbarium and the general herbarium), nor at BM, E, CGE or OXF, but at Paris there are two sheets (Herb. C.W.W. Hope 29 Jan. 1914) of D. affinis borreri, labelled as cultivated by P. Neill Fraser from plants sent to him by Wollaston as typical (P!). These specimens (along with his citing var. paleacea Moore [sensu Moore, pro parte = D. affinis| and var. borreri Newm. in his protologue) help to indicate that Wollaston's concept of Lastrea pseudomas was mixed and, as might be expected, he did not distinguish between what are now the constituent species of the aggregate, but referred to the more typical or characteristic "D. affinis-like" plants, more-or-less regardless of the modern species in the group. This further supports the suitability of the above lectotype of D. affinis as representing the "more characteristic" species. CONCLUSION Lectotypification in the present and most obvious sense has the effect of stabilising the current nomenclature of the group (see Fraser-Jenkins 2007) regarding the widely used name D. borreri, which might otherwise have been replaced by D. pseudomas had that been lectotypified from the other specimen on Wollaston's sheet. Although Fraser-Jenkins (1980) mentioned that L. pseudomas was illegitimate, he was merely misusing the term at that time to mean a synonym and has not subsequently thought of it as being illegitimate. In the same paper, when placing D. pseudomas in the synonymy of D. affinis subsp. borreri (Newm.) Fras.-Jenk., he had not then fully investigated the identity of many names applied to the group, as he did subsequently in his detailed unpublished monograph of the D. affinis group (copy at BM). The present lectotypification helps clarify the views expressed by Ekrt ef al. (2009), where it is suggested that D. pseudomas might apply to D. borreri.

The general species richness found in previous studies is low. This study presents an annotated list containing 122 species and three varieties of ferns and lycophytes from Biological Reserve of Uatuma, a large reserve that includes small patches of rich soils in Central Amazonia. The study site is located ca. 200 km north of Manaus, AM, Brazil. Inventories were made more intensively inside a grid system of trails of 5 x 5 km and less intensively in some white-sand forests and waterfalls in the surroundings of Balbina’s Village. Reference to the original description, habit, habitat, material examined, geographic distribution and voucher information are presented for each taxon. This is the first floristic survey of ferns and lycophytes from areas with relatively rich soils of Central Amazonia. The high number of species found challenges the concept that Central Amazonia is species-poor for the two groups studied and the strong relationship with soil conditions reinforces the proposal to include ferns and lycophytes as indicator groups of the distribution of biodiversity in the region. RESUMO Poucos séo os inventarios de samambaias e licdfitas feitos na Amazonia brasileira e a maioria destes foram feitos em areas cujos solos sdo pobres em nutrientes. Nao obstante, a riqueza de espécies encontrada em estudos prévios foi baixa. Neste estudo é apresentada uma lista anotada de 122 espécies e trés variedades de samambaias e licofitas da Reserva Biologica do Uatuma, uma reserva grande em extensdo e com pequenas manchas de solo rico na AmazOnia Central. O estudo foi realizado a cerca de 200 km ao norte de Manaus, AM, Brasil. Os inventarios foram mais intensos dentro de uma grade de trilhas de 5 x 5 km e com menor intensidade em areas de campinas e campinaranas e e cachoeiras nos arredores da Vila de Balbina. Para cada taxon sdo apresentadas informacdes acerca do local da publicagao original, habito, habitat, material examinado, distribuicaéo geografica e voucher. Este é o primeiro estudo sobre samambaias e licofitas em areas com solos relativamente ricos na Amazonia 287 FERN GAZ. 18(6): 286-306. 2009 Central. A alta riqueza de espécies encontrada afeta a idéia geral de que a Amazonia Central € pobre em espécies destes dois grupos e a forte relacdo entre as espécies e as condi¢ées do solo reforga a sugestao de se incluir samambaias e licdfitas como grupos indicadores da distribuicdo da biodiversidade. INTRODUCTION Central Amazonian soils are generally deep, highly lixiviated and nutrient-poor (Chauvel et al., 1987, Laurence, 2001, Mertens, 2004), and this may be the reason for the low species richness of ferns and lycophytes (39 to 83 species per site) reported in many inventories in this region (Costa et al., 1999, Costa et al., 2005, Zuquim et al., 2007). The same pattern is probably true for the Rio Negro Basin, which is mainly covered by poor sandy soils (Freitas & Prado, 2005). In Western Amazon, Tuomisto ef al. (2002) sampled relatively richer-soil areas and found 140 species in a 20 x 25 km study site in Ecuador. To contribute to the knowledge of the Brazilian Amazonian flora, we present here an annotated checklist of the species of ferns and lycophytes found in the Biological Reserve of Uatuma. Our evidence suggests that the low species richness in Central Amazonia sampled until now (as compared with other Neotropical forests) may be due to low sampling effort from the infrequent patches of rich soils that are difficult to access. MATERIALS AND METHODS Study area - the study was conducted at the Biological Reserve of Uatuma (Rebio Uatuma) and surroundings of Balbina’s Village, about 200 km to the North of the city of Manaus, AM, Brazil (Fig. 1). It is located in the municipalities of Presidente Figueiredo, Sao Sebastiao do Uatuma, and Urucara. The Reserve was created in 1990 and it is the largest Biological Reserve in Brazil. The reserve comprises a mosaic of white-sand shrublands (campinas), white-sand forests (campinaranas), and dense Terra Firme forests. The gradient of soils is broad and varies from very poor and coarse sandy soils to rich clayey soils. We have considered as rich soils those with more than 3 cmol/kg of exchangeable bases[(Research Program in Biodiversity (PPBio) - unpublished data] since this concentration represents around three times the amount found in the soils of the most studied areas in Central Amazonia (see Laurance 2001 - DBFFP Reserves, and Mertens 2004 - Reserva Ducke). Inventory of ferns and lycophytes Field work was carried out from July 2006 to February 2008. In 2006, the Research Program in Biodiversity (hereafter PPBio — the Portuguese acronym) with the support of the Chico Mendes Institute of Biodiversity Conservation installed a 5 x 5 km grid system of trails in the southernmost part of Rebio Uatuma (Fig. 1). Sampling effort was more intense in the trail system, and special attention was given to the streams crossing the trails. The trail system encompasses only 25 km? of the 5,600,000 km? of the limits of the reserve. The grid comprises non-inundated Tropical Dense Forest (also called Terra Firme forests) and is crossed by many streams. To cover the variety of environments found in the region, one waterfall and a surrounding campinarana area close to the village of Balbina were visited. These two habitats occur in the landscape but were not included within the grid system. ~ TUMA 288 ZUQUIM, PRADO & COSTA: A CHECKLIST OF FERNS FROM UA ‘poydures AJOAISUdIUT Bore OY] SMOYS SIeNbs dIYM OY] ‘[IZBIg “PLY “BUINIeA- JO dAIOSAY [BOISO]OIg OY} JO SHUM] IY] GB SOUT] PI[OS “UONRIISIA sjudsoidas soydied oyeos Avis puv Jo}VM JUDSOIdoI saYydjed yori ‘ojIs Apnys oy} JO UOIBIO7T *] ANSI D0) as Y9- ———a 289 FERN GAZ. 18(6): 286-306. 2009 Presentation of the checklist e list is arranged in alphabetic order by families, genera, species, and varieties.

Voucher information for each species and variety is also cited. Author abbreviations follow Pichi-Sermolli (1996). RESULTS One hundred and twenty two species and three varieties of sinnnagria distributed in 21 families were found. The richest families were Pteridaceae (with 22 species.), Polypodiaceae (18 spp.), and Dryopteridaceae (16 spp.). The most diverse genera were Adiantum (with 13 species) and Trichomanes (12 spp.). Near 35 % of the species are epiphytes, but these were probably underestimated due to the difficulty to access the canopy. Four species (Blechnum serrulatum, Gleichenella pectinata, Dicranopteris flexuosa, and Palhinhaea cernua) were found only in disturbed areas along road margins. Actinostachys pennula, Adiantum cinnamomeum, Lindsaea tetraptera, L. schomburgkii, mai plumosum, Thelypteris arborescens, Trichomanes bicorne, and T. martiusii were collected exclusively in white-sand forests (campinaranas). A none of around 50 individuals of Hemionitis rufa was found in a conspicuous rocky patch of ca. 100 m? covered by open vegetation (mainly grasses and ground bromeliads). Apparently, H. rufa is strongly related to this kind of habitat in Amazonia, but more observations are needed. The other species were distributed over habitats ranging from stream valleys to hillsides, plateaus, rocky soils and tree-fall gaps in the Terra Firme forests. Images of almost all species can be accessed by downloading the “Guide to the ferns and lycophytes of REBIO Uatuma — Central Amazonia” at http://ppbio.inpa.gov.br/Port/guias/. Two species (Schizaea elegans and Gleichenella pectinata) were accidentally not collected but are common in the region and are easy to recognise. Both were recorded in photographs.
