Abstract: | Alstroemeria hygrophila andA. orchidioides are both described as new from the state of Goiás (including Distrito Federal) in Brazil.Alstroemeria hygrophila is a cerrado bog-dwelling species that grows semi-epiphytically on the culms of a sedge. The vegetative stems of this species
characteristically zig-zag between the pseudonodes. Like other wetlandAlstroemeria in Brazil (e.g.,A. apertiflora, A. isabellana, andA. sellowiana),A. hygrophila has wiry stems bearing narrow, lanceolate, nonresupinate leaves, and does not form root tubers.Alstroemeria orchidioides is a hysteranthus forest understory species with large vegetative leaves aggregated at the apex of the stems. The leaves
on flowering stems are reduced to scarious bract-like scales. Its flowers are a pale, nearly white, greenish yellow, a color
not reported in any other Brazilian species. Both species have 2n=16 chromosomes. |
