Transit of Venus Botany

Today is the transit of Venus, when that planet passes in front of the sun. Hopefully the bad weather blanketing much of New Zealand doesn’t preclude at least some people from observing the event.

Observing the transit was one of Captain Cook’s primary objectives for the Endeavour expedition, and this was done in Tahiti in 1769. But the expedition had other aims as well, including exploration and discovery.

The botanists on board the Endeavour, led by Joseph Banks and Daniel Solander, collected plant specimens wherever the ship put to shore.

At noon this Friday (8th June 2012), Steve Cafferty from the Natural History Museum, London, will talk about the botanical discoveries made during Cook’s first voyage. Plant specimens collected from New Zealand by Banks and Solander will be on display.

Additionally, Te Papa Research Fellow Patrick Brownsey has just published an article about Banks and Solander’s collecting in New Zealand. The article is free to download from the Journal of the Royal Society of New Zealand until 31st July 2012.

Abstract of the article.

Te Papa holds over 500 specimens collected by Banks and Solander during the Endeavour expedition. High-resolution images of most of them are freely available from Te Papa’s Collections Online Website.

Kohekohe, one of the funkiest trees in town!

There are four reasons that make kohekohe (Dysoxylum spectabile) one of the funkiest trees in town    

First, unlike many other trees, Kohekohe flowers sprout from the trunk and branches. This feature is known as cauliflory and it’s believed to be an adaptation to pollination and seed dispersal by animals that can’t fly or insects living at the ground level.

Second, Kohekohe trees do not flower every year. Blooming generally occurs during early winter and after pollination of the flowers has occurred fruits will take up to 15 months to ripen. Thus, you will not see flowers on trees that are currently fruiting or vice versa.

Third, Kohekohe is the only representative in New Zealand of the tree genus Dysoxylum which is otherwise only found in tropical and subtropical regions of the world.    

Fourth, Kohekohe was one of the first trees collected in the country by the scientists Joseph Banks and Daniel Solander during the first trip of Captain James Cook to New Zealand in 1768. We  have this very first  sample of Kohekohe in our collection at Te Papa. This specimen is over 240 years old!      

  

You can see further details of this specimen  by visiting our collection on line!  http://collections.tepapa.govt.nz/objectdetails.aspx?oid=329062&term=Kohekohe 

 

Kohekohe trees were once common in coastal and lowland forests of New Zealand.  Nowadays, their number has been reduced due to habitat destruction and damage by possums. Fortunately you don’t need to go very far to see this interesting tree. There are several Kohekohe trees growing in Bush City and one of them is going to bloom any time soon! Don’t miss it!
