The Chromosome Numbers of 10 Species in the Genus Campylotropis (Fabaceae)
杭子梢属10种植物的染色体数目

This paper reports chromosome numbers of ten species and one variety of the genus Campylotropis from China (Table 1, Plate 1 ). They are C. argentea Schindl., C. bonatiana( pamp: ) Schindl., C. henryi Schindl., C. hirtella (Franch.)Schindl., C. macrocarpa(Bunge )Rehd., C. diversifolia( Hemsl. )Schindl., C. polyantha (Franch.) Schindl., C. polyantha( Franch. )Schindl. var. leiocarpa ( Pamp. ) Pet. -Stib., c. prainii ( Coll. et Hemal. ) Schindl., C. pinetorum (kurz)Schindl. ssp. velutina (Dunn)Schindl., c. trigonoclada(Franch. ) Schindl. The chromosome numbers of these ten species are all 2n= 22 or n= 11, but a few individuals in C. polyantha(Franch. )Schindl. var. leiocarpa(Pamp. )Pet. -Stib., were found aneuploid with 2n=23. The chromosome numbers of c. polyantha and C. macrocarpa have been reported by Maw-shing (1986)andLee(1972), while those of all the other species are first reported.
