 is perhaps unusual for the rhizome of a bamboo ; but this may be 

 attained by keeping the stem buried beneath the soil until it lias 

 grown to a suificient length. That this may be done as a system is 

 possible, when we know that in Algeria the young sticks of the 

 Medlar are gashed transversely, while they are growing, to give them 

 a knotted appearance, and so enhance their value in the market.

Mabattia fraxtnea, as now determined in the ' Species Filicum ' 

 of Hoolter and Baker, has a very extensive range, being noted as 

 found in South Africa, East Indies, Australia, and in several 

 islands of the Pacific ocean. In New Zealand it is found only in
