402 FOREST CULTURE AND 
a cultured spot. Altogether, 20 genera with 170 well- 
marked species are circumscribed by General Munro’s 
consummate care ; but how may these treasures yet 
be enriched when once the snowy mountains of New 
Guinea through bamboo jungles become ascended, or 
when the alps on the sources of the Nile, which Ptol- 
emy and Julius Cesar already longed to ascend, have 
become the territory also of phytologic researches, 
not to speak of many other tropical regions as yet 
left unexplored. Europe possesses no bamboo; Aus- 
tralia, as far as hitherto ascertained, only one (in the 
interior of Arnheim’s Land). Almost all bamboos are 
local, and there seems really no exception to the fact 
that none are indigenous to both hemispheres, all true 
Bambusas being Oriental. 
The introduction of these exquisite plants is one of 
the easiest imaginable, either from seeds or the living. 
roots. The consuls at distant ports, the missionaries, 
the mercantile and navigating gentlemen abroad, and 
so particularly also any travelers, could all easily aid 
in transferring the various bamboos from one country 
to the other—from hemisphere to hemisphere. Most 
plants of this kind here with us, once well establish- 
ed in strength under glass, can be trusted out to per- 
manent 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 tropical lowlands, but delight in the cooler air 
of mountain regions. In selecting the following ar- 
ray from General Munro’s monography it must be 
noted that it comprises only a limited number, and 
that among those which are already to some extent
