Abutilon fluviatile and A. peltatum were compared by Schumann (1891) using features of the leaf blades (entire with rounded base in A. fluviatile sub-trilobate with cordate base in A. peltatum). We here consider A. peltatum a synonym of A. fluviatile based on the analysis of material from the states of Minas Gerais, Rio de Janeiro and São Paulo, which show a large range of variation in relation to these characteristics, with specimens from the same locality having entire to sub-trilobate leaf blades, and rounded to cordate base, like those from the locality of Santa Genebra, in Campinas. Abutilon fluviatile is readily recognized by having mericarps dorsally covered in long, simple trichomes, and by its peltate leaf blades, the latter being considered unique for this genus in São Paulo. It is similar to A. amoenum and A. mouraei in the indumentum on the branches and calyx, but is distinctive in its acute to shortly acuminate calyx lobes, and mericarps with smooth dorsal suture. Conservation status:— According to the criteria found in Mamede et al. (2007) A. peltatum should not be considered a threatened species. Abutilon mouraei Schumann (1891: 410). Type: BRAZIL. Rio de Janeiro: Serra da Mantiqueira, s.a., A.F.M. Glaziou 13542 (lectotype P, duplicate C-4, K!, P, photo F-9278). Fig. 3L–N. Distribution and habitat:— Endemic to Brazil, only a few collections are known from Rio de Janeiro, Minas Gerais, and in the state of São Paulo, only two specimens from the same locality in Serra da Mantiqueira above 1200 m elevation, one of which was collected during fieldwork for the present research. It grows in wet areas in dense rainforest margins. Specimens examined:— BRAZIL. São Paulo: São Bento do Sapucaí, 17 August 1994, T . Y. Tamashiro 539 et al. (SP, SPF, UEC); 27 May 2010, C .

(SP). Abutilon mouraei is easily recognized by its cupuliform calyx with the basal portion rounded, and long simple white trichomes. It can be confused with A. amoenum, but is distinctive in its distribution, leaf characters, petals and mericarps as mentioned in the key. Conservation status:— According to the criteria found in Mamede et al. (2007) A. mouraei should be included in the Vulnerable category. Abutilon amoenum Schumann (1891: 41). Type: BRAZIL, s.l., s.a., F. Sellow s.n. (holotype B, photo F-9261!). Fig. 3F–G. Distribution and habitat:— Abutilon amoenum has a restricted distribution in the state of São Paulo, from Caraguatatuba to the south, spreading from there throughout the south of Brazil to Argentina and Paraguay. It grows in semideciduous forest and on margins of dense rainforest, often on riverbanks. Specimens examined:— ARGENTINA. Missiones: Monte Carlos, 3 January 1968, A . Krapovickas & C. L.

Silva (MBM, SPF). This is the first record of A. amoenum in the state of São Paulo. The material of this species found in several herbaria was mistakenly identified as either Abutilon costicalyx K.Schum. ex Baker or as Abutilon mulleri-friderici Gürke & K.Schum. The presence of glandular trichomes on the branches, petioles, pedicels and calyx, and the staminal tube inserted beyond the corolla, however, left no doubt as to the identification of these specimens as A. amoenum. Conservation status:— According to the criteria found in Mamede et al. (2007) A. amoenum should not be considered a threatened species. Abutilon longifolium Schumann (1891: 402). Type: BRAZIL. Minas Gerais: Quilombo to Bonfim, s.a., Pohl 3001 (lectotype W). Fig. 3A–D, 5I. Distribution and habitat:— Abutilon longifolium is endemic to Brazil (Minas Gerais and São Paulo). In the state of São Paulo, it has a restricted distribution, concentrated in the municipality of Monte Alegre do Sul and surroundings. It grows in dense rainforest, often on riverbanks.

Abutilon lanatum is here synonymized under A. macranthum because it presents the same diagnostic characters, especially the entire to sub-trilobate leaf blades, and the wooly branches and calyx. Abutilon macranthum has branches and calyx entirely covered with a wooly indumentum and elongate papillae. However, the material from Serra da Mantiqueira exhibits great phenotypic plasticity for these features, showing branches without papillae, velvety to pulverulent indumentum, and calyces with elongate papillae only along the nerves and basal portion. Because of these variations it can be confused with A. regnellii, but it differs from the latter by the leaf lobation, the staminal tube and mericarp morphology as mentioned in the key. In the state of São Paulo there are no records of these two species inhabiting the same localities. However, A. macranthum and A. regnellii occur sympatrically in the Serra da Mantiqueira (in the states of Minas Gerais and Rio de Janeiro), with the possibility of hybridization between these species, as was verified by material from these states. Conservation status:— According to the criteria found in Mamede et al. (2007) A. macranthum should not be considered a threatened species. Abutilon regnellii Miquel (1849: 554). Type: BRAZIL.

Abutilon striatum Dicks. ex Lindley 1839

Abutilon striatum Dicks. ex Lindley (1839: 39). Type: The Botanist 3: t. 144 (1839) (holotype). Fig. 3E, 5C. Distribution and habitat:— Argentina, Uruguay to Brazil (São Paulo, Paraná, Santa Catarina and Rio Grande do Sul). In the state of São Paulo it is known only from the municipality of Apiaí, next to Paraná where it was collected in this work. It grows in dense rainforest. Specimens examined:— ARGENTINA. Corrientes: Santo Tomé, 11 February 1972, A . Krapovickas 21585 et al. (CESJ). BRAZIL. São Paulo: Apiaí, 6 July 2010, C . Takeuchi & T. Takeuchi 74 (SP). Paraná: Adrianópolis, 28 July 1999, J. M .

This is the first record of Abutilon striatum in the state of São Paulo. The species was introduced worldwide as an ornamental, becoming somewhat spontaneous in many Neotropical countries and in Asia (Kearney 1958, Macbride 1956, Waalkes 1966). Abutilon striatum is characterized by the 3–5-lobed to parted leaf blades, and orange petals with reddish veins and yellowish basal spot. The flowers are notable for the length of the staminal tube (with reddish staminiferous portion), which is exserted beyond the corolla. The taxonomic relationship of this species with A. pictum (a species also distributed in southern Brazil and Uruguay) is not certain, due to the similarity in external morphology. They are regarded either as synonyms (Kearney 1958, Krapovickas 1999, 2008 b, Waalkes 1966) or as distinct species (Fryxell 2002). In the present account we follow Fryxell (2002). Variation in the coloration of the petals (yellowish, orange and pink) is reported especially in cultivated plants (Waalkes 1966), however in the the material from its native southern Brazil, it does not show plasticity for this character. Conservation status:— According to the criteria found in Mamede et al. (2007) A. striatum should be included in the Vulnerable category. Abutilon rufinerve Saint-Hilaire (1824: 205). Type: BRAZIL. "Valla do Principe, propèque praedium Domingo Alfonso", s.a., A. Saint-Hilaire s.n. (holotype P, isotype P-2). Fig. 4C–E. Distribution and habitat:— Abutilon rufinerve is endemic to southeastern Brazil (Espírito Santo, Minas Gerais, Rio de Janeiro and São Paulo), and southern Brazil (Paraná and Santa Catarina). In the state of São Paulo it is one of the species with the widest geographical distribution, occurring from the coast to the interior regions. It grows in dense rainforest and in semideciduous forest. In other states it also occurs in Cerrado and rocky grasslands. Specimens examined:— BRAZIL. São Paulo: Apiaí, 7 June 2010, C .

Saint-Hilaire (1824) and Schumann (1891) recognized three varieties, based mainly on the form of the leaf blades and the length of the flowers, but the material from state of São Paulo showed a wide range of variability in relation to these characteristics. Thus, it is not possible to assign the specimens to any infraspecific taxa. Abutilon rufinerve can be confused with A. longifolium, in having ferruginous indumentum and mostly narrowly elliptic to ovate leaf blades, but it is easily distinguished by its erect flowers, cupuliform calyx, yellowish anthers and calyx partially enclosing the schizocarp. Conservation status:— According to the criteria found in Mamede et al. (2007) A. rufinerve should not be considered a threatened species. Abutilon nigricans Esteves & Krapovickas (2002: 479).

Abutilon nigricans is easily distinguished by having leaf blades with invariably blackish veins, and calices glabrous and blackish at the base. It has the largest number of flowers per fascicle (up to 5), differing from other species with flowers either solitary, or with 2–4 flowers per fascicle, as in A. itatiaiae. Esteves & Krapovickas (2002) related it to A. bedfordianum (Hook.) A.St. -Hil. & Naud. mainly due to nigrescence sometimes observed in the vegetative parts, pedicel and base of the calyx. However, besides the distinctive characters mentioned, A. nigricans differs from A. bedfordianum in having entirely white petals, and papillate dorsal mericarp sutures. Conservation status:— According to the criteria found in Mamede et al. (2007) A. nigricans should be included in the Vulnerable category.Published as part of Takeuchi, Cátia & Esteves, Gerleni Lopes, 2012, Synopsis of Abutilon (Malvoideae, Malvaceae) in the state of São Paulo, Brazil, pp. 39-57 in Phytotaxa 44 (1) on pages 49-53, DOI: 10.11646/phytotaxa.44.1.4, http://zenodo.org/record/505906

Revisão taxonômica de Gaya Kunth (Malvoideae, Malvaceae) no Brasil

RESUMO Gaya inclui 39 espécies distribuídas na região Neotropical, com maior diversidade no Brasil e no Peru. No Brasil foram registradas 14 espécies, sendo oito endêmicas, predominantemente na região Nordeste, no domínio da Caatinga. O gênero caracteriza-se pelas flores pêndulas no botão e eretas na antese, pelo esquizocarpo inflado, pêndulo a ereto na maturidade, com mericarpos apresentando ou não uma estrutura interna, a endoglossa, que pode reter a semente, além de uma constrição no lado ventral ou na porção basal e deiscência por todo o lado dorsal até a constrição, sendo que estes dois últimos caracteres foram explorados pela primeira vez. Este estudo foi baseado na análise morfológica de cerca de 450 materiais de herbário. A taxonomia das espécies foi baseada sobretudo nos caracteres do fruto e da flor, com a detecção de novos caracteres diagnósticos. O trabalho consta de chave analítica, descrições morfológicas, ilustrações inéditas, comentários sobre variabilidade e relações taxonômicas, mapas e distribuição geográfica, novas ocorrências e dados de conservação
