EL CARIOTIPO DE BOMAREA PATINII BAKER SUBSP. PATINII (ALSTROEMERIACEAE) [PDF]
Gayana. Botánica, 2008 The karyotype oi Bomarea patinii Baker subsp. patinii from Colombia was examined. The species has a karyotype 2n = 2x= 18, with a haploid formula 2m + lsm+ 5st+ lt-sat. The reported karyotype is asymmetric (Asl %= 75.51). The most of the chromosomes are acrocentric. This results are compared with other species oiBomarea from South America.
