Naturalisation in Extra-Tropical Countries. 311 



Microseris Porsteri, J. Hooker. 



The Native Scorzonera of extra-tropical Australia and New 

 Zealand. A perennial herb, deserving attention, as its root would 

 probably enlarge and improve through culture. On alpine mountains 

 the plant develops most luxuriantly during summer. The Australian 

 aborigines use the root for food. The plant would prove hardy in 

 Middle Europe. In West-America about 20 species exist. 



Milium effusum, Linne. 



English Millet-grass. Europe, North- and Middle-Asia, North- 

 America. Perennial, suited for damp forest-land particularly, the 

 pastoral capabilities of which it enhances. On river-banks it 

 attains a height of 6 feet. It is relished by cattle. The seeds can 

 be used like millet, the stems for the manufacture of superior 

 straw-hats. It is a great favorite with pheasants and many other 

 birds for the sake of its seeds, which ripen early in the season. 

 Indigenous in Norway as far north as lat. 71 7' [Schuebeler], 

 Nutritious hay to the extent of 3 tons on an acre obtainable from 

 this grass [Coleman]. 



Mimosa rubicaulis, Lamarck. 



All India, extending to Afghanistan, ascending to 5,000 feet. A 

 hedge-bush, almost inapproachable, growing finally to tree-height. 

 It has proved hardy at Melbourne, enduring some frost. 



Mimusops Caffra, E. Meyer. 



Red Milkwood. South-Africa. A small tree on coast-dunes, 

 larger in inland forests. Wood hard, red, durable and much used in 

 waggon-work and farm-carpentry. M. obovata (Sonder) serves for 

 similar purposes [T. R. Sim]. 



Mimusops globosa, Gaertner. 



Central America. Tree, reaching a height of about 120 feet, 

 perhaps fit like many other Sapotacese for frostless extra-tropic 

 regions. The milky juice from cuts into the stem when exsiccated 

 forms the Balata of commerce, a substance in its qualities allied both 

 to Gutta-percha and India-rubber [Jenman]. Wood very dense and 

 also elastic. 



Mimusops Sieberi, A. de Candolle. 



West-Indies and Florida. Tree reaching 30 feet in height. 

 Fruit of agreeable taste [Sargent]. 



Monarda didyma, Linne. 



Eastern North- America. Hardy to lat. 59 55' in Norway. A 

 perennial odorous herb, producing the medicinal Oswego- or 

 Beebalm-Tea. M. fistulosa, L., and several others are also of very 

 strong scent.*' Their volatile oil contains thymol.
