Cymbidium canaliculatum growing wild on campus at JCU, Townsville, Queensland, Australia

Cymbidium canaliculatum
I was shown this little colony of Cymbidium canaliculatum by one of the James Cook University Estate workers recently while organising a log for a mount for the Myrmecophyla tibicinnis. These plants are growing on top of a tall dead gum (see image below) that had preciously been cut after it had died. The plants established on their own, and I also recently found another seedling growing just a stone's throw away from these plants on a small bottlebrush tree. It is really good to see these plants doing so well. The one in the foreground has previously flowered (see dried, spent spike stalk).

According to IOSPE, this species is found in the hollows of dead branches, and flowers in Spring. Here is a link to the university plant list, and the Atlas of Living Australia taxon page with distribution map and additional data.

Rhynchostylis gigantea alba flowering again

First flower opened today 17 June 2018, roughly a month earlier than previously. Note the yellow stippling
I have been waiting to see this old faithful again. This year it has produced about 85 blooms on two robust opposing spikes. The plant has flowered about a month earlier this year than previously, and was well fed from spike initiation through to flowering using "Garden basics plant food liquid fertiliser", which has a N:P ratio of 49:1; 4.9% N, 0.1% P, 2.4% K... makes you wonder what else is in it. It is easy to use and smells really rich, so I use it at about 2 ml per litre. The plants seem to enjoy this one - some recently mounted Myrmecophyla tibicinnis were given this fertiliser for the last few weeks, and they are all very quickly shooting new roots (see below), which is s really good sign. This species is usually quite reluctant to do anything for a while after being disturbed.
