2008 Plant Science Internship Graduation.

On Friday, the Interns completed their Plant Science Program. They were just as enthused as we were this time last year.

The science of plants opens new doors

A group of 10 plant scientists of the future have been trained by Australia’s best, while at the same time helping to collect, study and record plant species for the National Herbarium of NSW.

Botanic Gardens Trust Executive Director Dr Tim Entwisle will present completion certificates to students of its 2008 Plant Science Internship Program today and thank them for their contribution.

“This work experience was very hands-on; the students contributed a great deal to our scientific study of plant species. Their efforts included helping us to re-organise the Herbarium in accordance with the latest DNA studies,” Dr Entwisle said.

“DNA sequencing has opened up amazing opportunites for the Botanic Gardens. While students identified plants using books and the internet, their efforts will help us create a DNA barcoding system that will contribute to the goal of eventually identifying every plant on the planet.

“Plant DNA barcoding will one day be a simple ‘black box’ method for distinguishing one species from another. For example, it will be used to quickly inventory biodiversity in a protected area or to monitor shipments of plants for illegal trading and endangered species,” he said.

“To bring this project to fruition, we need high quality science to first describe and classify the things we want to identify. There are still lots of flowering plants, and probably many thousands of algae and fungi yet to be discovered, let alone described and classified,” he said. “There is work to be done and these new scientists are already making a major contribution.”

The NSW-based science students who currently study related topics at universities and TAFE’s, gave up their summer holiday period to take part in the seven week 2008 Plant Science Internship program which is largely funded by the Friends of the Gardens for the Botanic Gardens Trust.

Coordinator of the Intern program, Bob Makinson said the students were shown a wide range of plant communities on the Central Coast.

“During the program, we discussed the management implications of the areas we visited, with guest speakers from the National Parks and Wildlife Division of the Department of Environment and Climate Change,” Mr Makinson said.

“The interns also contributed greatly to maintaining the Herbarium’s collections. The purpose of the NSW Herbarium is to know and record everything about the Flora of NSW and nationally. Plants are also collected from South West Pacific and South East Asia.

“In the last four weeks of our 2008 Intern program, the really important work began. This is when the students were allotted tasks and work with science staff on research projects, he said.

As a going away present, one of the Amorphophallus titanum (Titan Arum or Corpse plant) growing in the Garden's Tropical Centre decided to flower for them, a rare but spectacular event:

The reason the plant is draped in black fabric is that the Tropical Centre staff are taking time-lapse photos of it as it opens. Once the flower develops, it grows remarkably quickly--around 10 centimetres a day. I took this photo on Friday, but by now it will have opened, revealing exactly why it's called a corpse plant. It emits a foul odour to attract pollinators that consume dead flesh.

The dimensions of a mature Amorphophallus titanum, from the Gardens' Fact Sheet.

spadix — 2 to 2.9 metres (7 to 12 feet)
leaf height — 6 metres (20 feet)
leaf width — 4.5 metres (15 feet)
tuber (corm) — 100 kilograms (220 pounds)

Boggling, all in all!

Central Coast Field Trip: Bulgandry

Last week was the Herbarium 2008 Plant Science Interns' field trip to the Central Coast, specifically to Warrah Reserve. We stayed at the Crommelin Biological Field Station, owned by Sydney University and which backs onto Warrah and is about a kilometre up from Pearl Beach.

As I mentioned, I was the cook, so my botanising was limited although I managed to take some photos, some of which I'll be posting here over the next few days. The food went pretty well. I made a huge vegie curry, and a pesto pasta chicken salad, as well as more sandwiches than I thought humanly possible. The interns and staff didn't starve or die from food poisoning, so I guess it was successful!

I thought that rather than posting photos here in chronological order, I'd present them by family or location. To start with, some orchids. There were both Cryptostylis erecta and subulata about, but I've already posted images of those, so here are some others.

This delicate orchid, Genoplesium fimbriatum, or Fringed Midge Orchid, is far smaller than the image might suggest. The flower is only around a centimetre in diameter. It lacks leaves and is found only on the Australian East coast. Here is the entire plant:

A rather more showy orchid is this Dipodium sp., a Hyacinth Orchid.

Both these specimens were found at the Bulgandry Aboriginal Site in the Brisbane Waters National Park. Below is the boardwalk surrounding ancient Aboriginal rock carvings, including that of "Bulgandry Man". You can see images of the carvings here.

Actinotus minor, a smaller species in the same genus as the more famous Flannel Flower of which I've previously posted an image, is plentiful at this site. The flower is tiny, and only with close observation would you realise that it's very similar to its bigger cousin.

Finally, the moist sandstone heath of Bulgandry is home to this, the Drosera spatulata, a tiny carnivore. The sticky, spatulate leaves, catch small insects.

I'll post again soon with some more images. Right now, I have to do what I thought I'd never want to do ever again: cook dinner!
