Abstract Species from two genera belonging to the
Alstroemeriaceae,
Bomarea and
Leontochir, were
cytogenetically studied and compared to determine their detailed
karyotypic composition.
Bomarea is a polytypic genus
represented by 100 species, with a distribution range from Mexico and
Antilles (24°N) to Argentina (29°S) and Chile (17–40°S). In
contrast
Leontochir is a monotypic genus, endemic to the
coastal area of the Atacama Desert in Chile (28°S).
Bomarea
salsilla,
B. involucrosa, and
Leontochir ovallei
have a karyotype 2
n = 18 with similar chromosome morphology.
These data confirm the close relationship between both genera,
suggested by earlier studies.
Keywords chromosomes; Leontochir;
Bomarea;
Alstromeriaceae
