 the naked branches, which in winter are destitute of 

 twigs). Leuiiminosre. A genus of 2 species, one of 

 which is a scarce native tree, the Kentucky Coffee Berry, 

 so called because its seeds were used for coffee west of 

 the Alleghanies before and during the Kevolutionary 

 War. It is a desirable shade tree for city streets, and is 

 especially interesting in winter. It is a clean, stout tree, 

 bright and graceful in appearance and free from disease, 

 growing from 30-Utf ft. high in cultivation, and not leaf- 

 ing out until tlie middle of I\Iay, after the other trees 

 are in full foliage. It is thornless and has coin]>ound 

 foliage. Grows with erect divisions. making narrow, pyra- 

 midal head. Branchlets very stout and destitute of 

 spray: tis, white, dicecious or polyganiotis, in terminal 

 racemes: pods long, hanging. Grows naturally in bot- 

 tom lands and richest soils. May he planted in any soil, 

 but thrives best in deep, rich, or rather hnniiij soil!
