Title: Brasiliorchis: A new genus for the Maxillaria picta alliance (Orchidaceae, Maxillariinae)
Author: Singer, RB
Koehler, S
Carnevali, G
Abstract: Brasiliorchis R. Singer, S. Koehler & Carnevali is here proposed to include the orchid species formerly recognized in the Maxillaria picto alliance, all orchid group mostly endemic to the Atlantic Rain 1, 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 slipes. Formal diagnosis of the genus and 13 taxonomic conibinations are presented: Brasiliorchis barbozae (Loefgren) R. Singer, S. Koehler & Carnevali, B. chrysantha (Barbosa Rodrigues) R. Singer, S. Koehler & Carnevali, B. consanguinea (Klotzsch) R. Siriger, 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 (Hoelne) R. Singer, S. Koehler & Carnevali. Leclotypes are designated for B. barbozae, B. chrysantha, B. heismanniana, B. phoenicanthera, B. picta, and B. polyantha. A neotype is proposed for A consanguinea. In addition, a key to distinguish Brasiliorchis from other sympatric bifoliate orchids within Brazilian Maxillariinae is presented.
