| Abstract: | A new Gorgonidium species from Bolivia, G. beckianum, is described and illustrated. It is characterized by its globular ovary, a subsessile, discoid stigma and shorter, slightly clavate and slender staminodes of the female flowers. G. beckianum is closely related to G. vermicidum and G. striatum, which mainly differ by an ovoid ovary, a distinct style and a star-like or subhemispheric stigma as well as by the shape of their staminodes. |

| Full Text | Years ago Dr Stephan Beck from the National Herbarium in La Paz (LPB), Bolivia, showed me herbarium specimens of several aroids, which he brought on loan to the Botanische Staatssammlung München (M). Included was an undescribed species of the South American genus Gorgonidium (Bogner & Nicolson 1988; Engler 1920; Mayo & al. 1997, 1998) of the small neotropical tribe Spathicarpeae (Gonçalves & al. 2007). It was represented by two collections, one flowering and one fruiting. The fruiting collection was easily identified as belonging to the same species, because of the ± sessile stigma, which is unique in the genus where all other species have a distinct style. The spadix of the specimen from LPB was highly attacked by a fungus. Since the flowering specimen was collected by a British collector, I asked for a loan and received a duplicate from the Kew herbarium (K), which is in much better condition and much less infected by a fungus. The species is described as new to science in the present contribution. |
