Pupulin, F & M.A. Blanco. 2002. A new species of Stellilabium section Taeniorhachis (Orchidaceae) from Costa Rica. Lankesteriana 5: 27.

Abstract. The new species Stellilabium smaragdinum is described and illustrated from the montane oak forests of the Cordillera de Talamanca, Costa Rica. Among the species of Sect. Taeniorhachis, S . smaragdinum may be recognized for the inflorescence bearing 1-3 (4) simultaneous flowers, the oblong to ovoid, rounded basal lobules of the lip, the non-ciliate margins of the lip midlobe and the peculiar colour of the column setae, cream banded with purple.

Williams, N.H., W.M. Whitten, & R. L. Dressler. 2005. Molecular systematics of Telipogon (Orchidaceae: Oncidiinae) and its allies: nuclear and plastid DNA sequence data. Lankesteriana 5: 163-184.

Abstract. Phylogenetic relationships of Telipogon Kunth, Ornithocephalus Hook. and related genera (Orchidaceae: Oncidiinae) were evaluated using parsimony analyses of data from the internal transcribed spacers of nuclear ribosomal (nrITS DNA) and three plastid regions (matK, trnL-F, and the atpB-rbcL intergenic spacer region). In addition to an analysis of 81 OTU’s for ITS only, we used a matrix of 30 taxa for combined nuclear and plastid analyses. Stellilabium is embedded within Telipogon and should be merged with the latter genus. Telipogon consists of two South American clades and a Central American clade. One Stellilabium clade is sister to the Central American clade of Telipogon, and the second Stellilabium clade is sister to all of the Central American species of Telipogon and Stellilabium. Hofmeisterella is a member of the Telipogon alliance. The genus Dipterostele is not supported by this work. Nomenclatural changes are made transferring Stellilabium to Telipogon.

Key words. Hofmeisterella, Ornithocephalus, Stellilabium, Telipogon, Oncidiinae, Orchidaceae.
