Abstract:

 This paper reports the chromosome numbers and karyotype analysis of Speirantha
gardenii, which is endemic to China. The material was collected  from  Huang  Shan,
Anhui. It is a diploid species. Its somatic chromosome is 2n=38=22m+6sm+10st. The
9th pair is submedian centromere chromosomes, but it has two constrictions.  The se-
condary constriction is on the short arm near centromere. Of the 19 chromosome pairs,
secondary constriction is present only in this pair.
