Narrative

Fruit resembles Seckel in size and form. Skin bright yellow in color with many small tan-colored dots, fairly attractive. Flesh quite gritty, but juicy and reasonably tender. Spicy, exotic flavor and aroma. Superior to some other Sand Pear hybrids in dessert quality. Tree of medium vigor, very productive, moderately susceptible to blight. -- H. Hartman, 1957.

'Griesa' may be a synonym for 'Douglas' (see PI 541723), which is also an Asian x European hybrid. Douglas is a Kieffer seedling introduced about 1910 by A.H. Griesa who suggested the cultivar name 'Douglas' for the Douglas County, Kansas where it originated. -- J. Postman, curator comment, 08/2012
