Grande, J.R., Kallunki, J., Arbo, M.M., Berry, P.E., Huber, O. & Riina, R. 2012. Botanical novelties from Sierra de Maigualida, southern Venezuela. II. Anales Jard. Bot. Madrid 69(1): 7-19.
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 Guayana Highlands of southern Venezuela. To date, one genus, 32 species, 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.
