Abstract: | The generic concept of Gelasine Herb. (Iridaceae) is reviewed, and the characters discussed in connection with Sphenostigma Bak., a synonym of Gelasine. The reduction of Sphenostigma is further justified on account of overlapping features. A new species from Uruguay, G. uruguaiensis Rav. sp. nov., is described and illustrated. This is shown to include two subspecies: ssp. uruguaiensis , and ssp. orientalis ssp. nov. The chromosome number of the latter is 2n = 14. |
