Chromosome Number and Chromosome Morphology in Helicophyllum crassipes
Nature, 1951Helicophyllum crassipes (Araceae)1 grows as a weed in the coastal belt of Egypt, in localities where the soil is light calcareous sand and where the percentage of salt is low. It is a corm-geophyte which sprouts late in October and flowers during January and February; flowering sometimes extends through March and April.

The Indian Journal of Pediatrics, 1963
The chromosome number has been determined in an Indian female adult, the first to be reported in this ethnic group. The chromosome studies were made on leucocytes obtained from the short-term culture of peripheral blood.

Chromosome Numbers in Cancer Cells
Nature, 1947DURING an investigation on the variation of the chromosome system in human cancer of the uterus, we were able to observe frequently (in six epitheliomas of the uterus portio) a mitotic figure with a peculiar aspect of the chromosomes. In such cell divisions (which appear mixed with normal, heteroploid and polyploid ones) 24 chromosomes are present ...

Chromosome Numbers in Holcus mollis
Nature, 1953INVESTIGATIONS into the interspecific relations of Holcus lanatus and H. mollis have shown that their F1 hybrids are male-sterile, having only 1–20 per cent of stainable pollen. Chromosome counts have been made on twenty-three of these hybrids with the results given in Table 1.

CHROMOSOME NUMBERS IN THE ANNONACEAE
American Journal of Botany, 1948which had induced them. When isolated from the normal stem tissue and grown in vitro, the induced tumors lost their characteristic structure and reverted to the structureless condition of the original tumor tissue. The theory is put forward that induced tumors may be composite structures into the make-up of which both normal and tumor tissue enter, the

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 IN THE MYRTACEAE
American Journal of Botany, 1947THE MYRTACEAE have received comparatively little cytological attention, partly because of technical difficulties, and partly because the majority of species are relatively far removed from the centers of intensive study. Cytology in its more recent developments has proved its value in clarifving some of the problems of phylogeny, and it appeared likely
