Naturalisation in Extra- Tropical Countries. 447 



already longed to ascend, have become the territory also of phy- 

 tologic researches, not to speak of many other tropical regions as 

 yet left unexplored ! Europe possesses no Bamboo ; Australia, as 

 far as hitherto ascertained, only five. Almost all Bamboos are 

 local, and there seems really no exception to the fact that none are 

 indigenous to both hemispheres, a remark which applies to Palms 

 as well, with the sole exception of Cocos nucif era, the nuts of which 

 indeed may have drifted from the western to the eastern world. 

 All true Bambusas are Oriental. Observations on the growth of many 

 Bamboos in Italy are recently offered by Chevalier Fenzi. The 

 introduction of these exquisite plants is one of the easiest imagin- 

 able, either from seeds or the living roots. The consuls at distant 

 ports, the missionaries, the mercantile and navigating gentlemen 

 abroad, and particularly also many travellers could all easily aid 

 in transferring the various Bamboos from one country to another 

 from hemisphere to hemisphere. Most plants of this kind, once 

 well established in strength under glass, can be trusted out in 

 climes of mild temperature to permanent locations with perfect 

 and lasting safety at the commencement of the warm season. 

 Indeed, Bamboos are hardier than most intra-tropical plants, and 

 the majority of them are not the denizens of the hottest lowlands, 

 but delight in the cooler air of mountain-regions. Strong manuring 

 brings some tardy flowering Bamboos early into bloom. In select- 

 ing the following array from General Munro's monograph, it must 

 be noted, that it comprises only a limited number, and that among 

 those, which are already to some extent known, several as yet 

 cannot be defined with precision in their generic and specific rela- 

 tion ; evidently some occur, which in elegance, grace and utility 

 surpass even many of those now specially mentioned :
