The seedless orange tree, from which are descended the greater part of these trees in the United States, was secured by Mr. William Sanders from Bahia. Its present appearance in the greenhouse of the Department of Agriculture is shown in Fig. 54. The naval orange is exceedingly beautiful as it grows upon the tree. A bunch of these oranges growing on the parent tree in Washington is shown in Fig. 55.
