is largely used for stuffing pillows and mattresses and for upholstering, 

 etc., both in the countries where it is grown and in those to which it is 

 exported. The largest supply conies from .Java, wiiere the trees are 

 grown as a secondary product. The wood is used to some extent In 

 interior construction, but it is soft, white, and brittle. The tree is 

 readily propagated from seed or cuttings and thrives from sea level up 

 to 2,000 feet. (Adapted from Macmilhin. Handboolc of Tropical Garden-

From Berkeley, Calif. Seeds presented by Mr. E.^B. Babeoclc, Division of

45558. Aquilegia tbacyi X chrysantha. Ranunculacese. Columbine. 



" Unguarded seed from Fi hybrids between Aquilegia tracyi $ and 

 A. chrysantha $ . Cross made in 1915. Parents and Fi plants now in 

 plant-breeding garden of the Division of Genetics, Department of Agri- 

 culture, University of California. This seed may produce extremely 

 variable offspring, some of which may be of greater ornamental value 

 than either of the parents." 



45559. Delphinium CABDiNALE X (?). Ranunculacese. Larkspur. 

 "Unguarded seed from an F, hybrid l)erween Delphinium cardinale [a 



red-flowered six^cies from southern California] and a garden hybrid with 

 deep-blue flowers. Cross made in 1915. Fi plants now in plant-breeding 

 garden of Division of Genetics, Department of Agriculture, University of 

 California. This seed may produce extremely variable offspring, some 

 of which may be of greater ornamental value than either of the parents."'

45560. "(No. 212. Avocado No. 26. City of Guatemala. November 13, 

 1917.) Manik. Bud wood of a productive and rather early variety 

 of excellent quality. It is a medium-sized fruit of pleasing form and 

 clear yellow flesh of unusually rich flavor. 



" The parent tree is growing in the flnca La Polvora, in Antigua. 

 The altitude is about 5,100 feet. AVhile it is growing among coffee 

 bushes and grevilleas, the tree is not crowded and has develoi>ed to 

 a large size. It stands about 50 feet high, with a rather slender 

 trunk and a dense crown, the trunk being 2 feet thick at the base and 

 branching about 8 feet from the ground. The age of the tree is prob- 

 ably 30 years or more. It is badly attacked by leaf-gall, but in general 

 has the appearance of a strong, vigorous variety, the branchlets being 

 well formed, long, round, and stout. The bud wood Is good, having 

 strongly developed eyes well placed for cutting. 



"Antigua does not experience severe frosts ; hence, it is impossible to 

 determine in advance of a trial in the United States whether or not 

 the variety is any hardier than the average of the Guatemalan race.
