GUNNERA. A genus of ivyworts, hav- 

 ing the following characters : perigone or 

 outer part of the flower usually adherent 

 to the ovary, its border in four pieces, two 

 of which are tooth-like, the other two re- 

 sembling petals but sometimes wanting ; 

 stamens two, alternate with the two small 

 lobes of the perigone; stigmas two, plu- 

 mose. The name was given by Linnseus 

 in honour of Ernest Gunner, a bishop of 

 Norway, who published a flora of that 

 country. The plants are herbaceous, na- 

 tives of South America and the Sandwich 

 Isles. One of them, G. scabra, is known in 

 gardens by its coarse rough rhubarb-like 

 lobed leaves, and its singular elongated 

 conical inflorescence. [G. D.] 



GUNNIA australis is the only epi- 

 phytal orchid of Tasmania, where it is 

 found growing on the stems of trees and 

 shrubs. It is a little plant, hardly a span 

 high, with wiry roots, a few lance-shaped 

 leaves three to four inches long, and 

 flower-racemes of about the same length. 

 The flowers, which smell like honeysuckle, 

 are small and green except the clawed lip, 

 which is marked with lilac lines on a white 

 and yellow ground. As a genus it is hardly 

 different from Sarcochilus, with which, 

 indeed, it is united by some authors. 

 Named in honour of Mr. R. C. Gunn of 

 ; Tasmania, who is well known in connection 

 with the botany of that island. [A. A. B.]
