Plant identification #2

Correct plant identification is not only important to make sure it is on Beckler’s plant list. 

Botanic art can be defined as ‘making science visible’. Its fundamental purpose is to help both scientists and lay people identify plants. Botanic art is not a still life painting of roses in a vase. It is an accurate painting that clearly shows the parts of a plant which allow the identification of that plant. So, a botanic painting of a rose would include details such as the shape, colour, form, leaves and probably hips — the aspects that allow it to be identified as a particular variety or species.

However, there is the artistic aspect and it is important. The artist makes the decisions on the medium to use, the composition of the painting, the focal point, the size and so on. The painting allows the personality of the artist to come through.

Cullen discolor

I don’t profess to be a top class botanic artist, and my painting skills are still developing. However, I am part of Beckler’s Botanical Bounty Project, which, in turn, is part of the tradition of botany in Australia. My painting needs to be accurate.

To be able to make my painting of Cullen discolor as accurate as possible I need to understand ‘tomentose to hispid’. My painting should show a surface that is between matted soft hairs and rough firm hairs. Whether it does is up to my painting skill. I need to know that the petioles are between 2 and 7 cms long so that my drawing doesn’t make them too long or too short. And so on.

My notes

As well, it is interesting to know that C. discolor grows in sandy soils, flowers September to January and is endangered in Victoria. Not many people know what C. discolor looks like. Nor do they know C. pallidum or C. cinereum. They are unlikely to look at my paintings and say “That’s not right”. However I will know and I want it to be as correct as my skills will let me. And it may just be used as an identification tool sometime in the future.

Plant identification

“Is it on the List?”

Hermann Beckler collected 120 different species of plants around Menindee. It is that list that the Beckler Botanical Bounty Project is using. So correct identification is very important!

The type of habitat where we were searching for our plants

I am a gardener, not a botanist. I find it hard to hold the Latin names in my head. I have no idea of many of the botanical plant terms. So identifying plants was a huge learning curve for me — and I am still only a little way on that curve!

We have been so lucky to have had the support of a botanist whose work takes him regularly to Kinchega National Park.  As you walk with him he points to plants and says, “That’s a so and so (fill in Latin plant name here), that’s a such and such (add different Latin name). That one over there is on Beckler’s list, this one isn’t.” So he was able to help sort plants in the field. That was a massive help.

Looking for the right plants

However much we would have liked it, he couldn’t always be with us. And sometimes he was unsure. So then it was back to the reference books.

I am working on plants from the genus Cullen. This year I was working on a species Cullen discolor. But I had to be sure that my identification was correct.

Cullen discolor

It is described as ‘a perennial herb with stems prostrate to 1.5 metres’. Okay, I get those terms. Then the description said ‘tomentose to hispid’. These I discover are descriptions of hairiness. Its leaves are pinnately 3 foliate, narrow to broad, lanceolate to elliptic and less pubescent on the upper surface. The margins are toothed. There are petioles and stipules, peduncles and calyxes — and I never got to dissect the flower, which has more specialised terminology!

Reference material

So, having nutted my way through the key, and gone to botanical dictionaries and other more knowledgeable people, I am confident that this is Cullen discolor.

“Perennial herb with stems prostrate to 1.5 metres.”

At least I knew that this Cullen was ‘on the list’. Some artists went through the identification process, only to find it was one that Beckler hadn’t collected. Then it was out into the bush again to repeat the process.

Hermann Beckler, botanical art and Menindee

Back in 1860 Hermann Beckler collected plant specimens during the Burke and Wills Expedition. (For posts about that check here and here.) Those specimens ended up in the Herbarium in Victoria. Now zoom forward 150 years to 2010, the 150th Anniversary of the Expedition.

There were a number of events and celebrations that year to mark the event. Mali Moir, respected and very talented botanic artist devised a botanic art project. After discussing her idea with some others the Beckler Botanical Bounty was begun. The idea was to go to Menindee, collect and press specimens of the same species that Beckler had collected. These specimens would sit alongside Beckler’s in the Herbarium. However, Mali’s truly fabulous inspiration was that each specimen would be painted. There is a list of 120 taxa collected in 1860 within 20km of Menindee. This list was the basis of our work.

So in 2010 the first group went to Menindee and began the process. I went in 2011 and 2012, and would love to be there again in 2013!

The broad process is that we identify the plant, collect it (with the correct permits, of course), press it and then start the painting. But things are not always that easy! Correctly identifying a plant can involve time, patience and some very thick reference books! Then there is a very good chance that it is not on Beckler’s list, so it is back outside again!

Collected specimens, ready to be pressed and stored

After the specimen is collected and pressed, the drawing and painting begins. If you are interested in finding out how individual artists go about their work you can follow the link to our Beckler’s Botanical Bounty Blog.
