Hah. " Collingwood " ; 1890: Cominuiiieated by lf?-s. ^S. 

 Featon. 



Obs. This peculiar and elegant flowering species of Metro- 

 slderos I lately received (with other botanical specimens) from 

 Mrs. S. Featon, of Gisborne, who had then recently obtained 

 it from Collingwood. It is allied to M.florida, Sm., bnt differs 

 from that species in several characters,- — besides those striking 

 ones of its yellow petals and their sub-laciniate margins. In 

 outline its petals approach those of M. rohusta, A. Cuun. ; but 

 these of this species are more largely veined and dotted. Spe- 

 cimens bearing mature fruit are much desired.
