摘要

O genero Brasiliorchis R. Singer, S. Koehler & Carnevali, é proposto para conter aquelas especies de orquídeas antes incluidas na Alianca Maxillaria picta; um agrupamento primariamente endémico do bioma Mata Atlántica, no Sul e Sudeste do Brasil. Este novo género é sustentado tanto por caracteres morfológicos quanto por estudos de biología molecular em andamento. O novo género é facilmente diagnosticado pelos seus pseudobulbos bifoliados, sulcados a canaliculados e pelas suas flores campanuladas, duradouras e sem recompensas florais. Os polinários destas especies normalmente carecem de estipes. Apresenta-se a diagnose formal do novo género, bem como treze novas combinacoes taxonomicas: Brasiliorchis barbozae (Loefgren) R. Singer, S. Koehler & Carnevali, B. chrysantha (Barbosa Rodrigues) R. Singer, S. Koehler & Carnevali, B. consanguínea (Klotzsch) R. Singer, S. Koehler & Carnevali, B. gracilis (Loddiges) R. Singer, S. Koehler & Carnevali, B. heismanniana (Barbosa Rodrigues) R. Singer, S. Koehler & Carnevali, B. kautskyi (Pabst) R. Singer, S. Koehler & Carnevali, B. marginata (Lindley) R. Singer, S. Koehler & Carnevali, B. phoenicanthera (Barbosa Rodrigues) R. Singer, S. Koehler & Carnevali, B. picta (Hooker) R. Singer, S. Koehler & Carnevali, B. polyantha (Barbosa Rodrigues) R. Singer, S. Koehler & Carnevali, B. porphyrostele (Reichenbach f.) R. Singer, S. Koehler & Carnevali, B. schunkeana (Campacci & Kautsky) R. Singer, S. Koehler & Carnevali e B. ubatubana (Hoehne) R. Singer, S. Koehler & Carnevali. Sao propostos lectótipos para B. barbozae, B. chrysantha, B. heismanniana, B. phoenicanthera, B. picta e B. polyantha. Propoe-se um neótipo para B. consanguinea.%Brasiliorchis R. Singer, S. Koehler & Carnevali is here proposed to include the orchid species formerly recognized in the Maxillaria picta alliance, an orchid group mostly endemic to the Atlantic Rain Forest Biome, in south and southeastern Brazil. The new genus is supported by both morphological features and ongoing molecular studies. The new genus is easily diagnosed by its sulcate to ridged, bifoliate pseudobulbs and its long-lasting, campanulate, rewardless flowers. The pollinaria of these flowers are normally devoid of stipes. Formal diagnosis of the genus and 13 taxonomic combinations are presented: Brasiliorchis barbozae (Loefgren) R. Singer, S. Koehler & Carnevali, B. chrysantha (Barbosa Rodrigues) R. Singer, S. Koehler & Carnevali, B. consanguinea (Klotzsch) R. Singer, S. Koehler & Carnevali, B. gracilis (Loddiges) R. Singer, S. Koehler & Carnevali, B. heismanniana (Barbosa Rodrigues) R. Singer, S. Koehler & Carnevali, B. kautskyi (Pabst) R. Singer, S. Koehler & Carnevali, B. marginata (Lindley) R. Singer, S. Koehler & Carnevali, B. phoenicanthera (Barbosa Rodrigues) R. Singer, S. Koehler & Carnevali, B, picta (Hooker) R. Singer, S. Koehler & Carnevali, B. polyantha (Barbosa Rodrigues) R. Singer, S. Koehler & Carnevali, B. porphyrostele (Reichenbach f.) R. Singer, S. Koehler & Carnevali, B. schunkeana (Campacci & Kautsky) R. Singer, S. Koehler & Carnevali, and B. ubatubana (Hoehne) R. Singer, S. Koehler & Carnevali. Lectotypes are designated for B. barbozae, B. chrysantha, B. heismanniana, B. phoenicanthera, B. picta, and B. polyantha. A neotype is proposed for B. consanguinea. In addition, a key to distinguish Brasiliorchis from other sympatric bifoliate orchids within Brazilian Maxillariinae is presented.
机译：Brasiliorchis R. Singer，S。Koehler＆Carnevali属被建议包含以前包括在Alianca Maxillaria picta中的那些兰花。巴西南部和东南部的MataAtlántica生物群落的主要地方性分组。形态学特征和正在进行的分子生物学研究均支持该新属。易于辨认的是其双叶假鳞茎，具沟纹的小鳞茎和钟形的，持久的无花果的花朵，容易诊断出该属。这些物种的传粉者通常没有柄。提出了新属的正式诊断，以及十三种新的分类学组合：巴西油菜（Loefgren）R. Singer，S。Koehler和Carnevali，B。chrysantha（Barbosa Rodrigues）R. Singer，S。Koehler和Carnevali，B近亲（Klotzsch）R. Singer，S。Koehler和Carnevali，B. gracilis（Loddiges）R.

Singer，S。Koehler＆Carnevali。提出了关于巴氏杆菌，B。chrysantha，B。heismanniana，B。phoenicanthera，B。picta和B. polyantha的选型。本文提出了一种新型的浓血双歧杆菌。建议在这里提出Brasiliorchis R. Singer，S。Koehler和Carnevali包括以前在Maxillaria picta联盟中被认可的兰花物种，该物种主要是大西洋雨林生物群落特有的兰花群。巴西南部和东南部。形态学特征和正在进行的分子研究均支持该新属。新属很容易诊断，它呈锯齿状，双叶假鳞茎和长寿，钟状，无奖的花。这些花的花粉病通常没有短柄。属的正式诊断和13种分类组合被提出：Brasiliorchis barbozae（Loefgren）R. Singer，S. Koehler＆Carnevali，B. chrysantha（Barbosa Rodrigues）R. Singer，S. Koehler＆Carnevali，B. consanguinea（Klotzsch） R. Singer，S. Koehler＆Carnevali，B. gracilis（Loddiges）R. Singer，S.
