We have named this most curious plant after our liberal correspon- 

 dent, Ronald L. Gunn, Esq. who is now examining the vegetation of 

 Van Diemen's Land, with equal skill and assiduity. The genus is 

 nearly related to Chiloschista,

For fine specimens of this we are indebted to Mr. Cunningham, 

 w^ho observed it " growing commonly in moist woods upon the shores 

 of the Bay of Islands, New Zealand, on mossy rocky banks, and on 

 the limbs of trees, flowering in September and October, which in New 

 Zealand is the season of spring." From the latter circumstance we 

 have contrived the generic name. 



This genus belongs to Malaxidese, and is related to Ccelogyne and 

 Dilochia, of the latter of which in particular it has much the habit, 

 only on a smaller scale. From the former its wingless column, 

 and from the latter the number of its pollen masses, sufficiently dis- 

 tinguish it, independently of other points of difference.
