Somatic chlomosome counts were made in root-tips taken fram the germinating seeds. Meiotic chromosome counts were made in micrasporocytes taken from flower bud material. Chramosome numbers were detnmined in 9 species as follows: Gevuina avellana Mol., 2n = 26; Nothofagus obliqua (Mirb.) Bl., 2n = 28; Sophora microphylla Ait., 2n = 18; Persea lingue Nees., 2n = 24; Embothrium coccineum Forst., n = 12; Laurelia sempervirens (R. et Pav.) Tul., n =24; Myrceugenella apiculata (DC.) Kaus., n = 11; Ugni candollei (Barn.) Berg., n = 9; Ugni molinae Turcz., n = 9. |
