slender-cylindrical, nearly as long as the albumen, straight; the 

 cotyledons semielliptical, several times shorter but not thicker than 

 the superior radicle. 



This plant is strictly referable to Cornese, a group seemingly 

 only discernible from Araliaceae by its bony putamen and perhaps 

 the length of the embryo. Koch (Synopa. Flor. German, i. 353) 

 records wrongly the embryo of Hedera Helix about as long as the 

 albumen. Bennett in his learned remarks on Polyosma (con£ Horsf. 

 Plant. Javan. rarior. 194) reduces the Alangiese to the family of 

 Cornese, which thus amongst Australian and New Zealandian plants 

 would comprise, Corokia buddleyoides, Corokia Cotoneaster, Grise- 

 linia lucida, Ehytidandra polyosmoides (F. M. Fragm. Phyt. Austr. 

 ii. 84 & 176). 



Polyosma Cunninghami, according to R. Br. (in Horsf Plant. 

 Javan. 196) is rather referable to Escallonieaa than to Cornese. Eecent 

 discoveries of new types of genera have, however, much invalidated 

 the formerly assumed characteristics of all allied orders. Thus the 

 genus Mackinlaya (F. M. Fragm. Phyt. Austr. iv. 119) renders the 

 transit from Araliacese to Umbelliferse almost complete. 



EUPHORBIACB^. 



EUPHOBBI^ Sp. 



A plant of this genus was observed in the Chatham-Islands by 

 Mr. Travers. It is most likely Euphorbia glauca (Forst. Prodr. 208 ; 

 AchiU. Rich. Voy. de rAstrolab. 352 ; J. Hook. Fl. Nov. Zeel. i. 227), 

 a plant common in New Zealand and to be found also in Norfolk- 

 Island. 



UMBELLIFER^. 



GlNGIDIUM DiEFFENBACHII. 



Tall, erect ; sheaths of the petioles produced at the summit in two 

 blunt teeth ; leaves thrice pinnatiseded ; their segments long, 

 linear, flat, flaccid, hardly or slightly spreading, seven-nerved, 

 short-mucronate ; rachis and rachillse imperfectly jointed ; floral 

 leaves with generally five segments and a petiole vaginate to the 

 summit; panicle consisting of numerous pedunculate compound 

 umbels ; leaflAs of the general a/nd special involucres very few, 

 narrow-lanceolate ; teeth of the male calyx short. 



On damp places under cliffs at the sea^shore.
