Abstract
Alstroemeria urubiciensis is an herbaceous species currently known only from a montane forest in the state of Santa Catarina, southern Brazil. It is morphologically similar to A. cunha, from which it differs by its greenish-yellow flowers, tepals with vinaceous longitudinal lines, and papillate bases on the outer tepals. The species exhibited a karyotype with 2n = 16, karyotypic formula 2ML + 2MS + 2SML + 2SMS + 8A, with no DAPI bands and CMA bands located primarily at the terminal regions of the short arms of acrocentric chromosomes.
