Obs. Genus fructus et seminis extus baccati indole inaxime affine 

 generi Talisiae , attarnen sat diversum genniue vix ima basi septato et 

 antheris extrorsis, nee non calyce et corolla 4-meris et inflorescentiis 

 racemosis bracteolis plerumque destitutis. lusuper, uti genus in Argentina 

 novissimo tempore detectum affine Diplokeltba, excellit foliorura fahrica, 

 quorum diachyma totum staurenchymaticum et meatihus iuterc-ellularihns 

 vix ullis instructum est, quod in Talisia non nisi in specielms paucis 

 (T. olivaeformis, subalbena, angmtifolia) occurrit; epidermidis (praesertim 

 paginae snperioris) cellulae hand raro in cellnlas secundarias 2 vel in 

 M. lepidopetala plures saepius rectaugulares parallelas divisae inveniuutur.
