seeds most of which were obviously ill developed. From the contents 

 of 6 capsules, 138 seeds (?), only 11 seedlings were obtained in seed 

 pans kept for 8 weeks; these 11 plants were brought to maturity. The 

 reciprocal cross 12'13 muricata W X gigas yielded a somewhat better 

 harvest; 8 capsules gave about 900 seeds (?), but only 85 seedling

developed after 8 weeks; -10 plants were brought to maturity. The plants 

 of these two reciprocal crosses were so similar to one another, except 

 for 4 individuals, that I was unable to find distinguishing peculiarities 

 of importance. They presented the characters of the parents closely 

 intermeiUate and without marked patroclinous oi' matroclinous tendencies, 

 except in the 4 peculiar plants to be described later.
