Mrs. C. writes. "I would like to ask you about some Sarracenias which we found during our southern trip. Two varieties we have not found described - one with a bright yellow flower, about the color of common prickly pear, grew very abundantly in Florida; the other a green flower, exactly the color of the leaf, in Virginia. My theory is, that the green one would change color on exposure to air and sun, as the Cobsea. We looked for them in the Smithsonian Herbarium, and the gentleman who has it in charge could give us no information, either from his own knowledge or his reference library. That suggests another question; which do you consider the best dictionary of botany, Johnson's, or Lindley & Moore's? I have been trying to get Chapman's Southern Flora, but fear it is out of print.

[These may have been forms of Sarracenia flava, which is a very variable species. Chapman's work went through two editions, and we are sure there would be a good demand for a third if Dr. Chapman could be induced to prepare it. Wood's Class Book of Botany describes southern as well as northern plants. As a mere dictionary, Johnson's is the best; but those who could afford it should have the "Treasury of Botany" also. It tells of so much more than the mere dictionary does. - Ed. G. M].
