Abstract
Pachytene chromosome morphology of the haploid complement of P. lanceifolia Nees (n=12) was studied. They are characterised by the presence of heterochromatic and euchromatic segments. An idiogram was constructed based on chro-mosome length, lengths of heterochromatic and euchromatic segments and arm ratios. Chromosome 11 has the nucleolus organiser in the totally heterochromatic short arm.
