EUPHORBIACE^ 473 



Euphorbia hypericifolia, Linn. 



First recorded by Cheeseman in 1882 from the streets of Auckland. 

 In the Manual (1906) he adds: "once well established, now nearly 

 extinct." 



Euphorbia ovalifolia, Engelm. 



First recorded by Kirk in 1895 as occurring on a heap of ballast 

 (from Buenos Ayres) in Wellington. It apparently did not spread. 



Euphorbia segetalis, Linn. 



In 191 2 Cheeseman reports this as found on sand-dunes at Tauroa, 

 near Ahipara, by R. H. Matthews and H. Carse. 



Euphorbia cyparissias, Linn. 



Also recorded in 1912 by Cheeseman; collected by J. W. Murphy 

 near Culverden, North Canterbury. 



Mercurialis annua, Linn. Dog's Mercury 



Recorded by W. W. Smith in 1903 as occurring in Ashburton 

 County. Has apparently not been collected since. 



Jatropha Curcas, Linn. Physic-nut 



Recorded in Hooker's list in 1864 as occurring in the Auckland 

 provincial district. Cheeseman writes me in 191 6: "I believe an 

 attempt to cultivate this at the Bay of Islands was made in the whaling 

 days, when it was probably seen by Hooker." It has certainly not 

 been met with since. 



Poranthera ericcefolia, Rudge 



Also recorded in Hooker's list in 1864. Said to have been col- 

 lected near Auckland by Dr Sinclair. Has not been seen since. It 

 is a New South Wales species. 



Ricinus communis, Linn. Castor- oil Plant 

 First recorded in Hooker's list of 1864 as R. Palma-Christi. 

 Cheeseman reports it as not uncommon in warm and dry localities 

 near Auckland. In the Manual (1906) he reports it from "waste 

 places on warm rich soils from Mongonui to the Waikato River, 

 not common." 



URTICE^ 

 Humulus Lupulus, Linn. Hop 

 First recorded by Kirk in 1877 from various spots in the neigh- 

 bourhood of Wellington, and then by Cheeseman in 1882 as an 

 occasional escape from cultivation in the Auckland district. In the
