ON VARIATION OF COLOUR IN THE FLOWERS OF WARRATAH. 37 
native Tulip (Zelopea speciosissima, var. alba), which he gathered on the 
Currajong range, near Richmond, New South Wales. ‘The inner bracts 
surrounding the base of the flower-head are white, the points having 
a narrow edging of crimson, whilst the outer are of a reddish-brown. 
The expanded flowers are of a delicate pure white, with the footstalks 
of a pale yellowish-green; the unexpanded flowers are towards the 
centre tipped with a pale yellowish-green, similar to that of the foot- 
stalks, which form an agreeable contrast to the pure white of the open 
flowers, but this is lost as the flower becomes expanded. The anthers 
are yellow, and appear to be fertile. This was the only flower found 
on the tree, and is a very fine grown one, measuring full six inches 
across. The foliage of this variety is similar in colour (a dull olive- 
green), but smoother and less serrated at the edges than that of the 
crimson flowering plant. A number of Warratahs, being a profusion 
of very fine flowers (for the flowers of the Warratah, as well as those of 
the Doryanthes excelsa, or Gigantic Lily, have been unusually abundant 
and magnificent in size and colour this season) of the normal brilliant 
and rich erimson colour, were growing about the same locality, but 
this was the only white variety observed. It would be interesting to 
procure the plant that produced this pretty variety, and by propagating 
from its roots or suckers ascertain if it could be perpetuated. An 
accurate and artistic drawing of this plant was obligingly made for 
me by Mrs. Meredith, of Tasmania, the distinguished author of the 
* Bush Flowers of Tasmania, and other works, and also by Miss 
Oliver, of Sydney. 
I had mentioned in a former paper (‘Journal of Botany,’ 1867, 
p. 140) that the best time to transplant the Warratah was when in 
flower, and when the flowering shoots described in the same paper are 
observed to arise from the base of one of the flowers ; this obtains also 
with most of the Australian plants, as they generally root and thrive 
well when removed at that time. 
I have observed a deviation, principally from the normal colour, in 
the flowers of other plants growing in the vicinity of Sydney, New 
South Wales, as well as in the Warratah; for instance, on Mr. Holt's 
estate at Cook's River, I found a variety of Epacris grandiflora, bear- 
ing a profusion of white flowers, the other shrubs of the same species 
growing with them, having the usual scarlet ones. In October, 
1866, I had an opportunity of examining some recently-gathered
