Abstract


Four new species, Siphocampylus acanthidiotrichus J.R. Grande (Campanulaceae), Phyllanthus huberi Riina & P.E. Berry (Phyllanthaceae), Sohnreyia maigualidensis J.R. Grande & Kallunki (Rutaceae), and Turnera maigualidensis J.R. Grande & Arbo (Turneraceae) are described and illustrated from the summit areas of Sierra de Maigualida in the Gua - yana Highlands of southern Venezuela. To date, one genus, 32 spe cies, one subspecies, and one variety of angiosperms are known only from the Maigualida meadows and shrublands, between 1800 m and the highest elevation areas at 2400 m. Here we describe the first iteroparous species for the genus Sohnreyia K. Krause, a Turnera L. species with apically villose, apiculate petals, and a Siphocampylus Pohl species with aculeiform hairs and pinnatisect leaves. The new species, Siphocampylus acanthidiotrichus, together with S. Tillettii Steyerm., represents a morphologically distinct subgroup within the genus.
