| São enfocados caracteres anatômicos diferenciais entre rizoma e escapo. Além da atividade dos meristemas apicais de ambos, no caule observou-se a presença e atividade do MEP (meristema de espessamento primário); os feixes vasculares, portanto, têm origem mista (do procâmbio e do MEP). No escapo, não ocorre MEP, portanto, os feixes são apenas de origem procambial. Entretanto, observou-se considerável atividade do meristema intercalar, o que produz o alongamento dos entrenós. |

| Background and Aims In 1976 the monotypic genus Hellmuthia was placed in the Hypolytreae s.l., but was subsequently ascribed to the Mapanioideae, tribe Chrysitricheae, mainly because of the presence in Hellmuthia of two lateral, mapanioid-like floral scales with ciliated keels, the anatomy of the nutlet, the embryo and the inflorescence. Recently, based on cladistic analyses and supported by pollen ontogenetic evidence, Hellmuthia was transferred to a Cyperaceae, tribe Cypereae, clade mainly consisting of Ficinia and Isolepis. In this study, the floral ontogeny in Hellmuthia was investigated and compared with the floral ontogeny in Paramapania, with special attention for the floral scales. Methods Freshly collected inflorescences of Hellmuthia... |

| Al het materiaal van de sectie Ammoglochin in het herbarium van Naturalis Biodiversity Center te Leiden (L), in totaal 1068 collecties, is gerevideerd om zo een beter begrip en een completer beeld van het voorkomen van de vijf inheemse soorten van deze sectie in Nederland te krijgen. Een sleutel is toegevoegd om (Nederlandse) planten van deze sectie te kunnen determineren.

| All the material of the section Phaestoglochin that is kept in the herbarium of Naturalis Biodiversity Center in Leiden (L), in total 817 collections, has been revised in order to get a better understanding and a more complete overview of the occurrence of the four native species of this section in the Netherlands: Carex divulsa, C. leersii, C. pairae and C. spicata. Carex muricata s. str. proves to be not native in the Netherlands. A key is provided for the identification of (Dutch) plants belonging to this section.
