near Mudgeeraba, flowered in the ■writer’s glass house 
and proved to be T. cyrnbiforme — a jump of a thousand 
miles south ! This means that that species probably 
occurs throughout the range of T. muelleri and also 
suggests that possibly T. w'ilManum does likewise, and 
finally that there are quite likely to be further discoveries 
made in this most interesting genus. 
Of the remaining three plants of this collection, two 
have produced buds which develop until they are almost 
ready to expand, then wither and fall. This could be the 
result of a changed environment, and the recent spell of 
very cold weather could be blamed were it not for the 
fact that their native habitat is much colder in winter 
~ N than Ipswich is. However, there are still some unde- 
veloped buds which may open later on. The third plant 
is more interesting. It, too, refused to open its buds, but 
before the segments withered the ovaries began to swell 
and now there are two well developed capsules so that 
it appears that the genus is capable of producing 
cleistcgamous flowers. Such flowers are not uncommon 
amongst the terrestrial orchids, but for some reason or 
other they are rare among the epiphytes.
