smooth, also eatable. A dye can also be prepared from its 

 pulp and that of allied species. Numerous other species are 

 industrially eligible for hedging purposes. 



Oreodoxa frigida, Humboldt. 



Central America, ascending the Andes to 8,500 feet. This 

 dwarf slender Palm may be chosen for domestic decorations. 



Oreodoxa regia, Humboldt. 



West India. This noble Palm attains a height of 60 feet. 

 It has proved hardy in Southern Brazil. The stem is thick- 

 ened at the middle, and from it, like from the much taller 

 O. oleracea (Martius) , starch can be obtained. 



Origanum Dictamnus, Linne. 



Candia. Like the following, a scent plant of somewhat 

 shrubby growth. 



Origanum Majorana, Linne. 



North Africa, Middle Asia, Arabia. A perennial herb, used 

 for condiments, also for the distillation of its essential oil. 



Origanum Maru, Linne. 



Palestine. Perennial and very odorous. 



Origanum Onites, Linne. 



Countries near the Mediterranean Sea. Somewhat shrubby 

 and strongly scented. 



Origanum vulgare, Linne. 



The ordinary Marjoram. All Europe, North Africa, North 

 and Middle Asia. A scented herb of perennial growth, con- 

 taining a peculiar volatile oil. It prefers limestone soil. O. 

 hirtum (Link.), O. virens (Hoffmannsegg), and O. normale 

 (D. Don) are closely allied plants of similar use. Several 

 other Marjorams, chiefly Mediterranean, are of value. 



Ornithopus sativus, Brotero. 



South Europe and North Africa. The Seratella or Serra- 

 della. An annual herb, larger than the ordinary Bird's-foot 

 Clover. It is valuable as a fodder plant on sterile soil. It 

 requires, like the smaller O. perpusillus, no lime, but improves 

 in growth on gypsum land. It thrives better on sandy soil 

 than on lime soil, according to Langethal.
