446 The Ohio Naturalist [Vol. VI, No. 3, 



5. Flowers having the corolla of the usual size with two 

 lateral lobes on the right or left side and three stamens on the 

 same side. Either the upper or the intermediate stamen seems 

 to be the additional one of the three. In a flower with two 

 corolla lobes and three stamens on the right side, the interme- 

 diate one was evidently additional, being only half as long as the 

 others and with a rudimentary anther. In all of these flowers 

 the usual upper stamen vestige was present and the calyx nor- 

 mal. In the descriptions "right and left" refer to the flower 

 and not to the observer. 



6. One flower, with two corolla lobes and three stamens on 

 the right side, had the left lobe distinctly but not deeply incised 

 in the middle and there was no trace of a third stamen. 



7. One flower of good size had two lateral corolla lobes and 

 three stamens on the left side and one lobe with two stamens on 

 the right. The upper lobes were separated by only a slight but 

 distinct incision and the stamen vestige was wanting. The 

 calyx was closed below and had an additional lower median lobe. 



8. A flower with two lateral lobes and three stamens on 

 each side. In this case the stamen vestige was present and the 

 calyx normal. 



9. A type of flower with the lower lobe of the corolla double, 

 and two well formed "lyras". One additional, median stamen 

 was developed below. This sometimes curved upward to join 

 the cluster of the other anthers, or in some flowers it was directed 

 nearly straight forward. The upper vestige was present and 

 the calyx was closed below and contained a sixth median, 

 inferior lobe. In 1904 two such flowers were seen and in 1905 

 at least one developed a normal two-parted fruit. 



10. One flower with the same peculiarities as those men- 

 tioned under S, but the left lower lobe and the left lyra were not 

 fully developed. The lower, median stamen filament was adnate 

 to the corolla its entire length, as also the lower half of the anther, 

 but the other half was standing out free. 



11. One flower with two lower lobes and two "lyras"; two 

 lateral lobes on the left side and one on the right ; with stamens 

 to correspond, three on the left and two on the right and one 

 inferior, median stamen. The calyx was entire and had an 

 additional, inferior, median lobe as in No. 8. 



12. One flower of normal size with two inferior lobes and 

 two "lyras." The lateral lobes were present but were separated 

 from the inferior lobe by incisions less distinct than usual. 

 There were three stamens, the upper pair and one inferior 

 median stamen longer than the two others. There was no trace 

 of the inferior pair but the vestigial stamen appeared as usual, 

 and the calvx was the same as in No. 8.
