and the deeper yellow of the petals. The sepal coloration late in 

 the season was the deep red of certain types of 0. yigas and certain 

 other types of LamarcJdana mutants, though less intense than that of 

 0. rubrinervis. The seed-capsules were longer than for 0. Lamarck- 

 i/uHt, though not so long as for O. rubrinerris. Each of the 8 indi- 

 viduals recognized came to flower as annuals, though slightly later 

 than the majority of Lamarcldanas surrounding them. A moderate 

 abundance of pollen was produced by most buds, which was found
