NKRTRRA DBPRKSSA, tim-i-tn.. van OBTDSA, Rud. Br. t var. nov. 



A variety distinct from the normal \ />r>'*sa in having all its JMTM obovate 



witli no suggestion of acuteness. 



Among the specimens of Nertera deprexsa gathered on Gough Island only one 

 plant of this variety was found. In the Kew Herbarium there is one specimen from 

 Inaccessible Island (Mosdey, Inaccessible Island, 16.8.73) of this variety. The other 

 specimens of this plant from Tristan da Cunha belong to the typical Nertera dfjtressa, 

 ami the variety does not appear to occur elsewhere. 



Distribution. Inaccessible Island.

COTULA GOUGHENSIS, Rud. Br., sp. nov. (Plate IV.) 



Herba annua erecta vel suberecta, 25 cm. alta inferne multe ramosa ; folia 

 sessilia fere amplexicaulia, bipinnatisecta, segmentis Innceolatis in apicem acutuni 

 rotundatis ; capitula folia non sujKjrantia, 8 mm. lata ; involucri bractoaa late ovatte vel 

 fere rotuudataj, marginibus integris ; Mores dimorphi exteriores ? uniserrnti sine 

 corollis, interiores cum corollis ; achenia comprcssa glabra. 



This species is quite distinct in its much blunter leaves and broad involucral bracts 

 from the Nightingale Island species, Cotula Moseleyi. It is near Cotula coronifolia, but 

 differs in having broad bracts and a smaller inflorescence. Cotula coronifolia is also in 

 general a much coarser plant. The only species of Cotula near this species as regards 

 the broad bracts is Cotula integrifolia, but in other respects this is quite distinct. 



Endemic in Gough Island, where it is very plentiful. 



Ilvf". H.I:I:I> GLABRA, Linn. Sp. PL, 810; D.C. Prodr., vii. p. 90. 

 Very probably an introduced plant here, as Mr Hemsley considers it to be in 

 Tristan da Cunha. 



Distribution. Almost cosmopolitan. 



SONCHUS OLERACEDS, Linn. Sp. PL, 792. 

 Common : probably introduced. 



Distribution. Tristan da Cunha and Inaccessible Island, and generally throughout 

 temperate regions. 



KOMEX OBTUSIFOLIDS, Linn, Sp. PL, 335. 



Probably introduced. It has not been recorded previously from the Tristan da 

 Cunha group. 



Distribution. Very widely spread in northern and southern hemispheres.
