Near Woburn (Druce) 7. The Lea District is a small irregularly shaped portion of the county which lies to the south of the Icknield Way, and has for its southern boundary the county of Herts, from which it is only artificially divided. The river itself rises from springs near Houghton Regis and from others in Leagrave Marsh three miles above Luton, and cuts through the chalk escarpment before entering Hert- fordshire. The greatest altitude of the district is about 630 feet. A small portion may belong to the drainage of the Colne, itself a Thames tributary. It has an expanse of grassy chalk downs, bare chalky arable fields, and woodlands where brick-earth gives the subsoil, and marshy ground about Limbury, and it includes also the rich park of Luton Hoo and its ornamental waters. Although the area is small it has had the advantage of being well explored by Mr. J. Saunders of Luton, so that the list of interesting species recorded for it is quite out of propor- tion to the area it includes. It will not be necessary to repeat the names of the plants common to the chalk downs, as they are already given for the Ivel and Ouzel districts ; the other interesting species found in this district include : — Onobrychis viciaeformis, Scop.
