natural grafts of roots in a wattle at Sunnybank, stem 
of a Myrtus with vine deeply imbedded in it, and a rust 
growing on Gnaphalium, new to Queensland. (2) By 
Mr. J. E. Young, clump of Sarcochilus Ceciliae, flower- 
ing and flourishing as a pot-plant; specimens of coal, 
oil-bearing shale, and granites from the Carnarvon 
Range, specimens of a rare elkhorn ( Plat y cerium 
Veitchii), nest of one of the Mason wasps, and a very 
large ant lion, all from the Carnarvon Ranges. (3) By 
Dr. E. 0. Marks, specimens of Fig Tree ( Ficus Watkin - 
siana ), and a seedling from it, differing considerably 
from the parent plant. Both trees were growing at his 
residence at Wickham Terrace. (4) By Mrs. and Miss 
Williams, flowers of Dendrobium undulatum , Cy rubidium 
Sparkesii, and Cy rubidium canaliculatum , cultivated at 
Brisbane, also a white sport of Ageratum conyzoides. 
(5) By Mr. C. T. White, lantern slides of Eucalypts of 
the Brisbane district, from photographs by Mr. W. J. 
Sanderson. (6) By Mr. F 1 . A. Perkins, lantern slides illus- 
trating the life history of several different types of 
insects. (7) By Mr. S. T. Blake, lantern slides of scenery 
mostly in the West and North-West of Queensland, show-

DENDROBIUM SCHNEIDERAE Bail. 
A New Northern Form. 
By the Rev. H. M. R. Rupp. 
Early in the spring of 1937, Dr. C. P. Ledward, of 
Burleigh Heads, paid a visit to Mackay. He explored 
part of the Enngella Range for orchids; and subsequently 
he sent me a small plant, apparently a Dendrob allied to 
D. monophyllum , which did not agree very well with any 
Queensland species hitherto described. Flowers were not 
seen. The habit and form were not unlike those of 
T). Schneiderae )/ but the living pseudobulbs were twice as 
large, and less wrinkled; the dimensions of the leaves 
were also twice those of the little southern species. Both 
Dr. Ledward ’s and my own plants are now (late Febru- 
ary, 1938) flowering. Racemes appeared before Christ- 
mas, and as they developed they soon greatly exceeded 
those of D. Schneiderae in length. One is now 17 cm. 
long, with 24 buds and flowers. Notwithstanding these 
disparities, as the first buds matured it became obvious 
that affinity with Z>. Schneiderae was very close indeed; 
.and we are now satisfied that the Enngella plant must be
