As the century drew to a close, the references became fewer and fewer. When the old growers died, the desire for large collections of Chinese tree peonies apparently died with thep:l. The varieties they had grown with the possible exception of P. papOflJemcea had full double flowers. They were so heavy that the stems could not properly support them, with the result that many of the flowers were hidden under the foliage. In addition to the varieties already mentioned, there were being grown under European names, one white, 'Lambertinae'; a few very beautiful salmon pinks and rose pinks such as 'Carolina d'Italie,' 'Comte de Rambuteau,' 'Jeanne d'Arc,' 'Marquis de Clapiers,' 'Mme. Stuart Low,' and 'Mme. Victor Gillier'; a gorgeous rose red or cherry red, 'Reine Elizabeth'; and a fine deep purple, 'Souv. de Ducher.'
