cribed also about the hybrid plant between P. orientale and P. 

 somniferum produced by Godron in 1866, some of which lived until 

 1875, in the, following manner : 



" Pflanze hochwuchsig, Bliithen kaum kleiner als bei P. orientale, 

 meist mit 6 Kronblattern. Pollen missgebildet, Kapseln vollg steril. 

 Im Uebrigen die Charaktere gemischt. Godron beobachtete an 

 mehreren Bliithen Fehren der Narbenpapillen, an zweien je 4 Kelch- 

 blatter, an einer beginnende Auflosung der Kapsel in einzelne 

 Carpelle." 



My Fj plants agree in many respects with the above description 

 but are characterized by the following points : 



1. Fj plants are generally perennial like o^ parent, more vigorous 

 than either of the parents, rhizome thicker, leaves more numerous in 

 the rosette. i:^ome individuals, died off after only one season like 

 ■^ parent. The hj'brid plants which germinated in autumn, flowered in 

 the next spring, while the offsprings of the parent mosth' passed 

 two winters before they flowered. 



2. The shape of leaf is intermediate between those of the male 

 and the female parents, and the stem and leaves are hispid like a^ 

 parent, with somewhat waxy surface like the -^ parent. 



3. The flowering shoot is generally unbranched like o^ parent ; 

 but in some individuals branched as in the -?- parent. 



i. Petals were single scarlet, either 4 or 6 and sometimes 5 like 

 cf parents, as in Focke's description. But there is one thing to 

 emphasize, that is, notwithstanding the fact that the doubleness of 

 the flower of Papaver somniferum is a dominant character over the 

 singleness in the same species, in the hybrid F^ plants it is found to 

 be recessive to the singleness of P. orientale, so far as the material 

 at hand has shown. 



5. The dehissence of anther is always incomplete, and the pollen 

 grains irregular in size, many of them being sterile. 



6. There were found no" such imcomplete capsules as Focke 

 described about the Godron's hybrids, but some individuals showed 

 polycephaloidy. 



Cytology of F, Plant 



Fj plants from the three kinds of crossings above mentioned 

 showed generally all the same diagnosis ; so they are mentioned 

 hereafter in this paper without distinction.
