THE BOTANY OF GOUGH ISLAND. 248 
folia non superantia, 8 mm. lata; involucri bractea late ovata vel 
fere rotundata, marginibus integris ; flores dimorphi exteriores 9 
uniserrati sine corollis, interiores cum corollis; achenia com- 
pressa glabra. 
This species is quite distinet in its much blunter leaves and 
broad involucral bracts from the Nightingale Island species, 
Cotula Moseleyi. lt is near Cotula coronifolia, but differs in 
having broad bracts and a smaller inflorescence. Cotula coroni- 
Jolia 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.

Distribution. Almost cosmopolitan.
