1) In a survey for the cucumber mosaic virus, 573 collections of mosaic plants have been made in the years from 1949 to 1955 in the vicinity of Tokyo, from 150 species of plants belonging to 47 families, and inoculated on the differential hosts. Of these collections, 202 samples (35%) from 68 species of plants (45%) in 32 families yielded the cucumber mosaic virus. 2) Among the hosts previously reported as naturally infected, 37 species were confirmed, in which, cucumber, muskmelon, tobacco, Primula sinensis, P. obconica, celery, pansy, Silene armeria, Stellaria media, Amaranthus blitum, beet, spinach, Commelina communis and corn are worthy to mention, as they are grown relatively common in Japan, and mosaic plants of them yielded the virus in higher percentage than 50. While, the cucumber mosaic virus was isolated hardly or not at all, from the following species: chrysanthemum, Campanula grandiflora, dahlia, marigold, redpepper, Physalis Alkekengi, bean, pea, Iris germanica, narcissus, hyacinth, tulip, calla, and lilies. 3) Thirty-three species and varieties of plants, previously unreported as hosts in nature, were found infected in the field. These were Chrysanthemum carinatum, Trichosanthes cucumeroides, Cucumis melo var. Makuwa, Luffa cylindrica, Myosotis scorpiodes, Cynoglossum amabile, Asclepias curassavia, Vinca rosea, Primula malacoides, P. veris, Cryptotaenia canadensis, Godetia amoena, Impatiens Balsamina, alsike clover, Raphanus sativus, Brassica rapa var. Komatsuna, B. napus, B. cernua, B. pekinensis, cabbage, Dianthus chinensis, D. superbus, Lychnis coronaria, Gypsophyla elegans, Cerastium vulgatum, Portulaca oleraceae, Gomphrena globosa, Amaranthus tricolor, buckwheat, Zingiber Mioga, Tradescantia reflexa, Pollia japonica, and Colocasia antiquorum. Among them, Chrysanthemum carinatum, Cucumis melo var. Makuwa, sponge gourd, Cryptotaenia, radish, buckwheat, and Cotocasia are grown rather common in the gardens, and have been found infected frequently by the cucumber mosaic virus. 4) Occurrence of mosaic plants of Commelina communis, Stellaria media, Trichosanthes cucumeroides, Cerastium vulgatum and Zingiber Mioga by cucumber mosaic virus are sufficiently common to be regarded as apart of source of infection.
