Melanodendron, D.C.

The native Black Cabbage-tree grows to a large, handsome, spread- 
ing tree, about fifteen feet high, on each side of the central ridge ; 
now the most abundant of all. It is covered with masses of 
white blossoms in the months of October and November. Plate 40.

Psiadia, Jacq. 
362. *P. rotundifolia, Hk. f. ; Solidago rotundifolia , Boxb. — Only 
one tree of this species is now known to exist in the world, and that 
grows in a field to the left of the entrance gates at Longwood, 
called The Black Field. Roxburgh states that the islanders 
called it Bastard Gum Wood, or Callage-tree. After a careful search, 
extending over a year or more, the plant above mentioned was 
discovered in the year 1868. It is a tree about twenty feet in 
height, and apparently very old. It grows side by side with a 
Gum Wood, and without close examination might be mistaken for 
that species ; indeed, I discovered it only by riding up to it to look 
for blossoms of the Gum Wood, and was surprised to find it 
covered with small white flowers of a different plant. It is much to 
be desired that a plant of such singular interest should be propa- 
gated before it is entirely lost. It flowers in May and June.
