C. W. Heers. Rose Notes from Queensland. ...On the other hand, Wyralla, which is capable of producing magnificent blooms, has disappointed, as the occasional crinkled flowers mentioned in our earlier descriptions have increased so much that it is being withheld for further observation. We are hoping that this is just a passing phase, due perhaps to the abnormal wet conditions.

p83. C. W. Heers, Notes from Queensland. The Pacific Nurseries have been testing out a number of varieties of their own raising and these will probably go on to the market in 1950. They include ....also a vigorous growing red, a seedling from Lemania, very dark and free blooming.

p92. Roses of Australia. Wyralla. H.T. (Heers) -This has been given the name of the red and black headed cockatoo, which, bearing in mind the dark shadings of the bloom, seems quite appropriate. It is a cross of Lemania and Ami Quinard. It is an extra strong growing variety with tall open growth and good foliage. The bloom is dark red with a velvet sheen, often darker than either of its parents. Petals number 25 to 30. When at their best, the blooms are large, high pointed, and of perfect shape. Unfortunately, occasionally the petals crinkle and incline inwards, giving, with the black shadings, a novel appearance which has had some admirers. Light damask scent and healthy foliage. A good garden rose which will often produce blooms of exhibition quality. Available 1950.
