Abstract

Coleocephalocereus superbus N.P.Taylor & Olsthoorn sp. nov. is described from the north-east corner of Minas Gerais state, Brazil. Its tuberculate seeds place it in C. subg. Coleocephalocereus, but it otherwise has a unique assemblage of characters which make its relationship difficult to assess: long hypertrophic spines at the stem base, caespitose habit with branches erect, cephalium of dark brown bristles and diurnal magenta flowers.

Coleocephalocereus superbus N.P.Taylor & Olsthoorn sp. nov. wird aus der nordöstlichen Ecke des Staates Minas Gerais, Brasilien, beschrieben. Die warzigen Samen ordnen die Art der Untergattung C. subg. Coleocephalocereus zu, aber ansonsten weist sie eine einzigartige Merkmalskombination auf, die eine Bestimmung ihrer Verwandtschaft erschwert: lange vergrößerte Dornen an der Stammbasis, einen gruppenbildenden Wuchs mit aufrechten Zweigen, ein Cephalium mit dunkelbraunen Borsten und sich tagsüber öffnende, magentafarbene Blüten.

Coleocephalocereus superbus N.P.Taylor & Olsthoorn sp. nov. é descrito a partir de populações encontradas no extremo nordeste de Minas Gerais, Brasil. A partir de suas sementes tuberculadas podemos colocá-lo em C. subg. Coleocephalocereus, mas um grupo de características únicas dificultam o delineamento de suas relações dentro do gênero: os espinhos hipertróficos na base da planta, hábito cespitoso e ramos eretos, além do cefálio com cerdas castanho-escuras e flores diurnas de coloração magenta.
