Naturalisation in Extra- Tropical Countries. 309 



Oreodoza frig-ida, Humboldt. 



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

 slender Palm may be chosen for domestic decoration. 



Oreodoxa oleracea, Martius. 



West-Indies, up to nearly 5,000 feet elevation. One of the most 

 rapid growing of all Palms, rising to a height of 120 feet. In 

 highly manured moist ground the Palm-Cabbage, which in this 

 species is of exquisite nut-flavor, can be obtained in two years 

 [Imray, Jenman], should ever such a culture become desirable. 

 Hardy in Florida [B. Smith]. 



Oreodoza reg-ia, Humboldt. 



West-Indies. This noble palm attains a height of 60 feet. It 

 has proved hardy in Southern Brazil. The stem is thickened at 

 the middle, and from it, as from that of 0. oleracea, starch can be 

 obtained. Found to be of easy growth and drought- resisting in 

 South-Queensland. 



Origanum Dictamnus, Linne. 



Candia. Like the following, a scent-plant of somewhat shrubby 

 growth. With 0. vulgare in medicinal use since Hippocrates' 

 time. 



Origranum Majorana, Linne. 



North- America, Middle Asia, Arabia. A perennial herb, used 

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

 employed in French factories of scented soap [Dr. Piesse]. In 

 Norway it will grow to lat. 70 22' [Schuebeler]. 



Origanum IMaru, Linne. 



Palestine. Perennial and very odorous. 



Origranum Onites. Linne. 



Countries at and near the Mediterranean Sea. Somewhat 

 shrubby and strongly scented. 



Origranum vulgare, Linne. 



The ordinary Marjoram. All Europe, North- Africa, Northern 

 and Middle Asia. In Norway it is indigenous to lat, 66 16 

 [Schuebeler]. A scented herb of perennial growth, containing a 

 pleasant volatile oil. It prefers limestone-soil. Of importance 

 also as a honey-plant. hirtum (Link), virens (Hoffmannsegg) 

 and O. normale (D. Don), are closely allied plants of similar use. 

 Several other Marjorams, chiefly Mediterranean, are of value. 

 Their seeds maintain vitality for a few years.
