Luteum, if really distinct, is certainly very near to pur- 
pureum. The chief differences we perceived, consisted in 
the foliage of luteum being contemporaneous with the in- 
florescence, while in purpuwreum it does not appear till long 
after the decay of the flower; in the anthers of luteum be- 
ing nearly equal to the naked part of the filaments, in pur- 
pureum twice shorter; in the interstamineous sinuses of the 
‘coronal web being unindented in luteum, in purpureum bi- 
dentate; in the segments of the limb of the corolla in luteum 
expanding wider and being narrower than in purpureum, 
where the flower is altogether smaller. Could we have 
compared fresh plants of the two, perhaps other marks of 
distinction might have occurred. 
The three species as yet known are natives of New Hol- 
land. The present was observed by the party who per- 
formed the late expedition to the south-west of the colony, 
bey en the Blue Mountains. The two others by Mr. 
rown. 
The drawing was taken from a plant that flowered in 
the fine collection of Mr. Griffin, at South Lambeth. It 
ripened its fruit, of which a representation is given in the 
annexed plate. The seed was about the size, colour, 
and consistence of a largish pea, at the period we saw it. 
The seed-vessel consisted of a thin sphacelate membrane. 
A greenhouse plant.
