Trians (qui species herbariorum Kewensium necnon Parisiensium sedule serutatus est, miraque 
sagacitate disposuit) pro maxima parte secuti sumus. Species omnes in herbariis Kewensibus servatas 
examinavimus, characteresque generieos auctorum omnium confirmavimus. Generatamen in omni- 
bus fere tribubus et precipue in Miconieis, etsi pro parte admodum naturalia, adhuc pessime limitata 
sunt, uam species stepe plures vel anomalas vel dubias includere necesse est.
