Dr Sandy-Lynn Steenhuisen and Ruth Cozien at a spot high up in the Maloti-Drakensberg World Heritage Site, close to Sentinel Peak, photographing a Drakensberg crag lizard underneath the leaves of the ‘Hidden Flower’.

Flowers high up in the Maloti-Drakensberg World Heritage Site made world news when it was discovered that the Drakensberg Crag Lizard is their sole pollinator. 

This first for continental Africa – a plant being pollinated by a lizard – is a discovery by a research group including Dr Sandy-Lynn Steenhuisen, Senior Lecturer in the Department of Plant Sciences and affiliate of the Afromontane Research Unit (ARU) at the Qwaqwa Campus of the University of the Free State (UFS), in collaboration with Dr Timo van der Niet, Prof Steven Johnson, and project leader Ruth Cozien, all from the Pollination Ecology Research Laboratory and Centre for Functional Biodiversity at the University of KwaZulu-Natal.

Besides their work being published in popular news here in South Africa (including an isiZulu article), it has also received coverage in, among others, Belgium, Canada, the Netherlands, and the United States of America. 

Is it a bee, a bird, perhaps a mouse?

‘Hidden Flower’, true to its name, is a plant species with flowers hidden at ground level, underneath the leaves of the plant. Like the leaves, the flowers are also green. With the flowers filled with nectar (up to 1 ml per plant) and strongly scented, one concludes that, just as with other flowers, these flowers must be visited by a pollinator. Is it a bee, is it a bird, perhaps a mouse/non-flying mammal?

According to Dr Steenhuisen, who was brought into the project because of her experience with rodents pollinating proteas, many plants are adapted to attract and be pollinated by a specific animal. They attract their pollinators using particular scents and colours and reward them for their service with, for example, nectar, oil, fragrance, and sometimes even shelter. 

The ‘Hidden Flower’ initially had the group of researchers thinking that it was being pollinated by a non-flying mammal. “Everything about the plant made it look like it should be mammal-pollinated,” Dr Steenhuisen said. 

They investigated all options, using several techniques to assess the contribution of different possible animals to set seed. To further assist them in their quest to find the true pollinator, the team put up motion cameras that recorded activity in the area of the ‘Hidden Flower’. 

Great was their surprise when studying the video material after a week of fieldwork in the mountains, finding shy lizards dipping their snouts in the ‘Hidden Flower’ and lapping up the nectar.

Dr Steenhuisen described this discovery as completely bizarre, exciting, and fascinating. 

To make 100% sure that lizards are pollinating the ‘Hidden Flower’, these animals were excluded from the plants. Results published in a paper in Ecology showed that when the lizards were experimentally excluded from the plants, the number of seeds produced dropped dramatically by almost 95%. This finding helped to further prove their discovery. 

Strong scent and bright orange colour attract

The team researched the new phenomenon and found that although flower visitation by lizards is not unknown, it occurs almost exclusively on oceanic islands. Cozien says one should keep in mind that mountains are like sky islands and might therefore have similarities with oceanic islands in terms of their ecology.

The strong scent and the touch of orange at the base of the inside of the flowers is believed to play an important role in attracting lizards. The little lizard may recognise the spots of orange inside the flowers which resemble the orange colour of a male lizard in mating season, attracting females. Lured by the strong scent and the orange spots, the reptiles stick their snouts into the flower in search of nectar, pollinating the ‘Hidden Flower’; thus, making sure that this flower will continue to grow on the slopes of Sentinel Peak in the Maloti Drakensberg range. 

This research finding on lizard pollination, which reads almost like a fairy tale with its islands, hidden flowers, nectar from the gods, and little dragons, shows that there are still many unknown and surprising interactions that need to be discovered and conserved to ensure a healthy ecological system. 

The research findings of this study were published in April 2019.

Moshoeshoe - lessons from an African icon - by Prof Frederick Fourie
2004-11-03

(The full text of the article that appeared in City Press and Sunday Independent)

Our understanding of history informs our understanding of the present. No wonder the contestation over historical figures in South Africa’s past is so fierce and so divisive.
The question is: could it be any other way? I would like to think that it could; that black and white South Africans, across linguistic, cultural, religious and other divides, can develop a shared appreciation of our history – at least with certain periods and personalities as a starting point.

One such personality whose legacy I believe offers a possible platform for unifying our still divided country is King Moshoeshoe, who lived from 1786 to 1870, and is acknowledged as the founder of the Basotho.

King Moshoeshoe is the topic of a documentary that has been commissioned by the University of the Free State as part of its Centenary celebrations this year. It is part of a larger project to honour and research the legacy of Moshoeshoe. The documentary will be screened on SABC 2 at 21:00 on November 4th.

Moshoeshoe rose to prominence at a time of great upheaval and conflict in South Africa – the 19th century, a time when British colonialism was entrenching itself, when the Boer trekkers were migrating from the Cape and when numerous indigenous chiefdoms and groupings were engaged in territorial conquests. It was the time of the Difaqane, a period when society in the central parts of the later South Africa and Lesotho was fractured, destabilised and caught in a cycle of violence and aggression.

In this period Moshoeshoe displayed a unique and innovative model of leadership that resulted in reconciliation, peace and stability in the area that later became Lesotho and Free State. It made him stand out from many of his contemporaries and also caught the attention of his colonial adversaries.

Such an evaluation is not a judgment about which model of leadership is right and which is wrong, or which leader was better than another; but merely an attempt to explore what we can learn from a particular exemplar.
|
Historians point to the many progressive leadership qualities displayed by Moshoeshoe which he used effectively in establishing the Basotho nation and in defending it.
First, there is his humanism and sense of justice worthy of any great statesman. Confronted by a situation in which cannibals murdered and devoured his grandfather, Moshoeshoe chose not to take revenge. Instead he opted to rehabilitate them and feed them as he believed hunger drove them to cannibalism.

Secondly, there is his skilful alliance-building with his contemporaries such as Shaka in an attempt to neutralize those rivals who were intent on attacking his followers. This is also displayed in the way he sought the protection of the British to keep the Boer forces at bay.
Thirdly, his emphasis on peaceful options is also seen in his defensive military strategy which saw him retreat to a mountain fortress to be able to protect and build a burgeoning nation in the face of the many forces threatening its survival.

Fourthly, there is his remarkable inclusivity and tolerance for diversity which saw him unite disparate groups of refugees from the violence and hunger that displaced them and then weld them into the Basotho nation. He also engaged with French missionaries, inviting them to stay with him and advise him on Western thought, technology and religion.
These are but some of the qualities which belie the notion that all 19th century African leaders were merely marauders and conquerors that gained their ascendancy through violence. Instead Moshoeshoe is a prime example of the human-centred, democratic and pluralist roots of South African, indeed African society.

The Moshoeshoe project that we have initiated (of which the documentary, called “The Renaissance King”, forms but one part) derives from our location as a university in the Free State, a province with a particular history and a particular political culture that developed as a result of this very model of leadership. This province has benefited tremendously from leaders such as Moshoeshoe and president MT Steyn, both of whom many observers credit with establishing a climate of tolerance, respect for diversity of opinion, political accommodation and peaceful methods of pursuing political objectives in the province. Their legacy is real – and Moshoeshoe’s role can not be overstated.
In addition the project derives from the University of the Free State being a site of higher learning in a broader geo-political sense. As a university in Africa we are called upon to understand and critically engage with this history, this context and this legacy.
Besides the documentary, the UFS is also planning to establish an annual Moshoeshoe memorial lecture which will focus on and interrogate models of African leadership, nation-building, reconciliation, diversity management and political tolerance.

In tackling such projects, there may be a temptation to engage in myth-making. It is a trap we must be wary of, especially as an institution of higher learning. We need to ask critical questions about some aspects of Moshoeshoe’s leadership but of current political leadership as well. Thus there is a need for rigorous academic research into aspects of the Moshoeshoe legacy in particular but also into these above-mentioned issues.
While the documentary was commissioned to coincide with the University of the Free State’s centenary and our country’s ten years of democracy, it is a project that has a much wider significance. It is an attempt to get people talking about our past and about our future, as a campus, as a province and as a country – even as a continent, given the NEPAD initiatives to promote democracy and good governance.

The project therefore has particular relevance for the continued transformation of institutions such as universities and the transformation of our society. Hopefully it will assist those who are confronted by the question how to bring about new institutional cultures or even a national political culture that is truly inclusive, tolerant, democratic, non-sexist, non-racial, multilingual and multicultural.

I believe that the Moshoeshoe model of leadership can be emulated and provide some point of convergence. A fractured society such as ours needs points of convergence, icons and heroes which we can share. Moshoeshoe is one such an African icon – in a world with too few of them.
