Sievers of California is credited with the origin of Kthel Crocker, but it was not grown from Cali- fornia seed, and Siever's glass treatment of carnations at San Fran- cisco tends to normalize their nature to the requirements of the 50- degree isotherm. A higher mean annual temperature by greenhouse methods may, if it has not already done so, evolve a new species of carna- tion adapted to a higher artificial or natural isotherm than 50 de- grees.
