“…Allotetraploids with sets of dissimilar chromosomes are not likely to form quadrivalents a t meiosis but autotetraploids with their four sets of homologous chromosomes may be expected to show tetrasomes. Tetravalents have been described and figured for Datura (BELLING and BLAKESLEE 1924), Aucuba (MEURMAN 1929), Solanum ( JORGENSEN 1928, LESLEY and LESLEY 1930, LINDSTROM and Koos 1931, Prunus (DARLING- TON 1928), Hyacinthus (DARLINGTON 1929b), Pyrus (DARLINGTON and MOFPETT 1930), Dahlia (LAWRENCE 1929, Primula sinensis (DAR- LINGTON 1931), Rosa relicta (ERLANSON 1931). The proportions of tetravalents present are widely various.…”

Tetraploid plants of Oenothera have appeared in a number of lines under investigation and from unrelated material. The first plant, gigas from Lamarckiana, was discovered by DE VRIES (1901) in 189.5 and he records that gigas also arose from seed of sublinearis in 1898 and from the cross 1ataXhirtella in 1899 although the latter of these two plants did not mature. MACDOUGAL (1907) reports the appearance of one plant of gigas from his cultures of Lamarckiana and SCHOUTEN (1908) lists three plants from commercial seed of Lamarckiana. HUNGER (1913) from large cultures of Lamarckiana grown in Java records five plants of gigas. HERIBERT-NILSSON (1909, 1912 described a plant from Swedish Lamarckiana with characters chiefly those of gigas, and GATES (1915) determined its tetraploid chromosome count. GATES (1913) identified as Lamarckiana gigas a line from the botanic garden of Palermo and showed it to be tetraploid. A dwarf, gigas nanella, from the original line of gigas has been studied by LE VRIES (1901, 191.5), and SCHOUTEN (1908) obtained a number of these plants. BOEDIJN (1920) established a dwarf tetraploid from Lamarckiana mut. simplex of DE VRIES. Making allowance for the fact that chromosome counts were not made on some of the plants early reported as gigas there are still substantial records of the appearance of this tetraploid from Lamarckiana through a number of different lines.Tetraploids out of species of Oenothera other than Lamarckiana or its derivatives have been recorded from several sources, the most important of which are the following: BARTLETT (1915a, b) reported gigas from Oenothera stenomeres and 0. pratincola. STOMPS (1916) reported tetraploids from the cross Lamarckiana gigas X atrovirens. A line of grandij6ra gave tetraploid plants to DE VRIES (1918) and to BOEDIJN (1924). STOMPS (1925) obtained from a cross between biennis and biennis cruciota, a biennis gigas, and crosses of this tetraploid with biennis cruciata gave biennis cruciata gigas. Plants of biennis cruciata gigas sulfurea were shown by STOMPS in the exhibition garden of the Sixth International Congress of Genetics a t Ithaca in 1932. There has also been recorded the appearance of tetraploids from crosses of gigas and semigigas with certain hybrids (BOEDIJN 3 924). To this list may now be added a tetraploid by way of my line of Oenothera franciscana B, a species with all pairing chromosomes.

“…From the observation of irregular distribution of chromosomes in metaphase II, it may be supposed that the numerical non-disjunction occurs in some quadri valents at anaphase I. This irregular distribution has been noticed by many authors who have studied chromosome behaviour of autotetraploids which form multivalents, e. g., Lesley and Lesley (1930), Kostoff and Kendall (1935) and Upcott (1935) in Lycopersicaum esculentum, Howard (1939) in Brassica oleracea and Tanaka (1940) in Carex siderosticta.…”

“…Trivalent and univalent formation, instead of some quadrivalents in autotetraploids, have been stated in many instances, e. g., Lesley and Lesley (1930) and Upcott (1935) in Lycopercicum esculentum, Morinaga and Kuriyama (1937) in Brassica Napella, Howard (1939) in Brassica oleracea, Tanaka (1940) in Carex siderosticta and Sinoto and Sato (1942) in Tricyrtis f ormosana, etc. This may be attributed to the failure of chiasma formation in the paired segment of one chromosome, and the smallness of chromosomes of B. chinensis will be accountable for the high frequency of univalents in my present case.…”
