Abstract
Since Research Note No. 18, "Collecting and Propagating the Seeds of California Wild Plants," was issued in December 1937, additional information on handling seeds of California species has been accumulated. This information is assembled in the following tabulation, which lists 178 different species, arranged alphabetically by genera. For each species, as in the previous paper, the following information is given in tabular form: Time of seed collection, approximate number of seeds per pound, days elapsed between sowing the seed and germination, highest germination percentage obtained, and suggestions for any necessary treatment of the seed. With 254 species listed in Research Note No. 18, the total number of plants whose propagation has so far been investigated by this Station is brought up to 432.For the technique of treating difficult seeds the reader is referred to Research Note No. 18, in which the subject is fully discussed.
