1. Chromosome number 2n=36 was determined for all Japanese species of Dichocarpum, and 2n=26 for D. arisanense and D. adiantifolium. But the latter may be 2n=24 including a pair of chromosome with a big satellite. If so, the basic number for Dichocarpum is x=6.2. In Isopyrum thalictroides whose chromosome number is 2n=14, a tetraploid, 2n=28, was found.3. Glutamate dehydrogenase from leaves of 80 species of Ranunculaceae were resolved into 10 anodal migrating bands. The zymograms are variable among the family, but the position of main band is considerably stable. The main band is band 1 in Japanese species of Dichocarpum, band 4 in D. arisanense and D. adiantifolium, and in Enemion, band 6 in Aquilegia, band 7 in Semiaquilegia, and band 8 in Isopyrum manshuricum.4. Petals of Dichocarpum, Semiaquilegia and Aquilegia were studied ontogenetically. The primordium becomes flat blade first. Then a transverse ridge appears at the basal part of adaxial surface of the blade. The ridge develops into the adaxial wall, and then both walls are connected in cup-shaped blade. The stalk is elongated later, and the spur elongated lastly.5. Cleistogamous flowers are produced in Dichocarpum nipponicum and D. ohwianum, but the floral organs are not so reduced.

1。染色体数字2n = 36均确定所有日本二色泡种类，而D. Arisanense和D. adiantifolium为2n = 26。但是后者可能是2n = 24，其中包括一对带有大卫星的染色体。如果是这样，Dichocarpum的基本数字为x = 6.2。在染色体数为2n = 14的Isopyrum thalictroides中，发现了四倍体，2n = 28.3。将80种ranunculaceae叶片的谷氨酸脱氢酶分解为10个阳极迁移带。 Zymogram图在家族中是可变的，但是主带的位置相当稳定。主带是日本二色帕普姆物种中的带1，在D. Arisanense和D. adiantifolium中的带4，以及在Enemion中，在Aquilegia中的Band 6，Semiaquilegia的带7和Isopyrum Manshuricum的Band 8。二色质的花瓣，半喹吉尼亚和阿克酸酯的花瓣进行了化学研究。原始块首先变成平坦的刀片。然后在刀片的轴向表面的基部出现横向脊。山脊变成了朝外的墙壁，然后两个墙壁都用杯形刀片连接。茎稍后伸长，刺激伸长，最后伸长。5。二色龙尼普氏菌和D. ohwianum产生了褶皱的花朵，但花器官并没有减少。
