OBSERVATIONS ON CHROMOSOMES OF FOURTEEN MOSS SPECIES FROM THE QINLING RANGE,CHINA
秦岭十四种藓类植物的染色体观察

The chromosome numbers in fourteen moss species from the Qinling Range, and karyotype of Mnium lycopodioides are reported in this paper. Immature capsules were used as material. Bryum capillare L. ex Hedw was found, to have n=10; Mnium lycopodioides Schwaegr. n = 6 with the karyotype formula n = 6 = 3m 3sm (1SAT) ; Plagiomnium maxi-moviczii (Lindl. ) T. Kop. n = 6; Bartrarnia halleriana var. elongata Turn. n=10 2m; Thuidium delicatulum (Hedw. ) Mitt. ri=ll; Thuidium philibertii Limpr. n=10 m; Hy-grohypnum ochraceum (Wils. ) Loesk. n=10; Drepanocladus uncinatus (Hedw. ) Warnst. n = 7 3m; Campylium chrysophyllus (Brid. ) J. Lange. n = 10; Brachythecium starkei (Brid. ) B. S. G. n==6; Brachythecium buchananii (Hook. ) Jaeg. n = 6; Brotherella yokohamae (Broth. ) Broth. n=9 2m; Gollarnia neckerella (C. Mull. ) Broth. n=7; Poganatum Jastigiatum Mitt. n = 7. No report on the chromosome number of Brotherella yokohamae and Gollania neckerella has been found. The chromosome numbers in Brachythecium starkei and Brachythecium buchananii (Hook. ) Jaeg. are different from previous reports, while the others are in accordance with the previous reports.
