Record Chromosome Number in a Mammal?
Nature New Biology, 1972CROSS has reported1, 2 chromosome complements in rodents ranging up to 2n=84 (in the North American geomyid Geomys breviceps) and 2n=86 (in the heteromyid Dipodomys merriami). Matthey has contested3 this claim; he maintained that in Geomys bursarius 2n =70 or 72 and he doubted whether a higher number had been confirmed. Numbers in the 2n=70 to 80 range

CHROMOSOME NUMBERS IN UMBELLIFERAE. V.
American Journal of Botany, 1971Chromosome numbers are reported for nearly 300 collections of Umbelliferae. Of these, 150 representing “new” or variant counts are figured. Karyotypes of fifteen of the genera included have apparently not been documented before.

Chromosome Numbers of Cerastium Species
Nature, 1950THE chromosomes of four species of Cerastium, namely, C. vulgatum, C. alpinum (including C. alpinum lanatum), C. arvense and C. perfoliatum, have been counted from root-tips of young seedlings. I give here a list of chromosome counts made by previous workers, none of which is of British material, together with my own counts.

The Number and Morphology of Moss Chromosomes
Stain Technology, 1954The time that suitable cytological material is available can be extended by bringing mosses into the laboratory in late winter and keeping them in covered glass dishes placed in strong diffuse light. Best growth of the gametophyte occurs at 68-70° F. and at a relative humidity just high enough to prevent the leaves from curling.

Chromosome Number of Human Endometrium
Nature, 1954THE determination of chromosome number in human somatic tissues has been the cause of controversy from time to time. Recently, Timonen1 made an extensive study on the variations of the chromosome number in the human endometrium in the proliferative stage.
