 growing on the sandstone cUffs of Chiloe. Both this and Gunnera

 or 10 inches in diameter, and the 

 plant will climb by means of small 

 adventitious roots to a great height 

 over rocks, trees, or buildings. The 

 leaves are leathery and shining, the

 I. A. moschatellina (Common Moschatel). — The only species. A 

 small herbaceous plant 4-6 inches high. Each plant bears several 

 dehcate root-leaves and two smaller leaves half-way up the stem. 

 The flowers grow in terminal heads of 5 each, the upper flower with 

 4 petals and 8 stamens, the four side flowers having 5 petals and
