204 Select Plants for Industrial Culture 



Lotus tetrag-onolobus, Linne. 



Countries on the Mediterranean Sea. Though annual, this herb is 

 highly valued for sheep-pastures. The green pods serve even as a 

 culinary vegetable. The allied L. siliquosus (Linne) is perennial, 

 and occurs in a succulent form on sea-coasts. The seeds will retain 

 their vitality for several years. 



Loxopterygium Lorentzii, Grisebach. 



La Plata-States. The bark, called Quebracho Colorado, exten- 

 sively used for tanning; latterly much exported to Europe. The 

 length of time for the tanning process with this bark is only half that 

 for oak-bark. The kino of this tree has come into therapeutic 

 use. 



Lupinus albus, Linne". 



The White Lupine. Countries on the Mediterranean Sea, also in 

 the Orient. An annual quick-growing, herb, valuable when young 

 for fodder and also for green manure. In Norway it will grow 

 to lat. 70 22' north (Schuebeler). It is famed as the " Tramoso " in 

 Portugal, to suppress sorrel and other obstinate weeds by its close 

 and easy growth. The lentil-like seeds, after the bitter principle 

 (lupinin) has been removed through boiling or soaking in salt-water,, 

 are edible. It would lead too far, to enumerate here many others of 

 the numerous species of lupines, of which unquestionably very many 

 are eligible for agrarian purposes, while all are acceptable as hardy, 

 elegant and easily grown garden-plants. One, L. perennis, L., extends 

 in America to the Northern States of the Union and Canada; fourteen 

 are recorded from South-Europe, seventeen from Brazil, and numerous 

 species from other parts of America, where the limits of the genus 

 are about Monte Video southward and about Nootka- Sound north- 

 ward. The majority of the species are perennial. The Egyptian L. 

 Termis (Forskael) and L. Graecus (Boissier) are closely allied to L. 

 albus and of equal use; their flowers are bluish or blue. 



Lupinus angustifolius. Linne". 



Countries on the Mediterranean Sea. An annual blue-flowered 

 species, preferable to L. luteus for grain-harvest. Hardy to lat. 70 

 in Norway. Some if not all lupines can be counted among honey- 

 plants. 



Lupinus arboreus, Sims.* 



California. This has been used there for the reclamation of sand, 

 on account of its long tap-roots, the latter having been traced to a 

 depth of 25 feet, while the stems were only 3 feet high. The ger- 

 mination is easy and the growth rapid on the sand-downs. For aiding 

 the young lupines during the first two months, to get hold of the sand, 

 barley is sown with them, as the latter sprouts in a few days and holds 

 the sand in the second week; the lupine subsequently covers the sand 

 with a dense vegetation in less than a year.
