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. 



Luculia gratissima, Sweet. 



Himalayas and Ava, at elevations of from 4,000 to 6,000 feet. A 

 tall shrub or small tree. Important in the series of plants destined 

 to maintain garden-fragrance well throughout the year, the copious 

 large blossoms being developed in the coolest season. The plant 

 hates frost and dry heat, [Gaerdt]. The flowers will likely be accept- 

 able for perfume-factories. 



Liipinus 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., ex- 

 tends 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 

 northward. 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 angustif olius, 



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 reclamation on 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-dunes. 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 subse- 

 quently covers the sand with a dense vegetation in less than a year.
