Art. XLV. — Notice of the Discovery of the genus Ehagodia in New Zealand. 

 By T. P. Cheeseman, F.L.S. 

 [Read before the Auckland Institute, 4th June, 1883.] 

 The genus Ehagodia was founded by the late Bobert Brown, marjy years 

 ago, on some half-dozen Australian plants agreeing in most characters with 

 Chenopodium, but easily distinguished by the fleshy fruit. Several species 

 have since been added, thirteen being described in the " Flora Australi- 

 easis ;" but up to the present time all of these were supposed to be strictly 

 confined to the Australian continent. Some little interest is therefore 

 attached to the discovery of one of the species in New Zealand, both from 

 its adding a new genus to our Flora, and from affording additional proof of 

 the intimate connection existing between the plants of the two countries. 

 My specimens, which are clearly referable to Brown's Ehagodia nutans, the 

 most widely distributed of the species, were obtained during a recent expe- 

 dition of the Auckland Naturalists' Field Club to the island of Otatau, 

 which, with Bakino and some smaller islets, guards the entrance to the 

 eastern passage to Auckland Harbour. The plant is abundant all round 

 the shores of the island, and on some of the smaller adjacent ones, usually 

 trailing over the rocks a little distance above high-water mark. The fol- 

 lowing short description may be useful to those who have not access to the 

 " Flora Australiensis " or other systematic works : — 



Ehagodia nutans, B. Br. Prodr. 408 ; Benth. Fl. Austral. 5, p. 156. A 

 much branched, prostrate or procumbent, herbaceous plant. Branches 

 6-18 inches long, sometimes hard and almost woody at the base. Leaves
