The derivative endures the climate of the mountain plantation 
better than the parent. In both places the derivative uniformly 
exhibits a greater amount of red in the leaves than the parent. 
At Carmel the reddish color is accompanied by a yellowish tinge, 
the green of the parent remaining practically unchanged. The 
parent is characterized by an excessive development of the basal

terminated by dense broad rosettes or by inflorescences. Here,

(see pls. XV and XVI) and are more noticeably angled. The deriva-

dense tufts of small reddish bractlike leaves or inflorescences. The 
capsules of the derivative at Carmel are generally few-seeded. This 
may be ascribed to the fact that the pistils here are generally longs 
than the stamens and are exserted from the bud, thus preventing
