What exactly is an orchid?

Orchid

When Jules and I were in Kleinmond we saw a sign saying that there were some orchids growing in the fynbos. We wondered what makes an orchid an orchid. So here it is…

Orchids are the most diverse family of flowering plants – 25,000 species!

What makes an orchid an orchid?

  • They have both the male and female reproductive structures fused into a single structure called a “column”.
  • Every orchid bloom has 3 sepals (the leaves just around the flower) and 3 petals.
  • They also (usually) have a highly modified petal called a lip, or labellum – a landing pad for bugs.

Other interesting facts:

  • Vanilla is actually an orchid! It is the only orchid widely grown for non-beauty reasons.
  • The largest orchid can grow to more than 20m long.
  • The name “orchid” comes from the Greek root orkhis, meaning “testicle”.
  • In their natural environment, each orchid species is dependent upon a specific type of insect to carry out its pollination.

Economist article on the South African economy

There is an interesting article on the South African economy in a recent edition of the Economist:

Basically, it says that the South African economy is going very well. However, some people (e.g. trade unions) feel that this growth is not benefiting the poor enough and that the government should be taking more drastic steps.

In this kind of argument I always think of the Kennedy quote: “A rising tide lifts all boats”. I suppose their problem is that not all boats are lifted equally…

Here are some of the interesting excerpts from the article:

  • “When South Africa’s apartheid regime conceded power in 1994, it also bequeathed an economic shambles. The government’s budget was in the red, interest rates were uncomfortably high, and the country’s economy was as distorted as its society. But this fiscal year, for the first time, the government is running a surplus.”
  • South Africa’s economy “has grown by more than 4% in each of the past three years.”
  • “About half the population falls below the poverty line, according to some estimates. And although the economy creates 500,000 jobs a year, unemployment remains stubbornly high.”
  • “Local governments (municipalities) struggle to hire managers and engineers, leaving many essential posts unfilled”

Swimming at the Red Bridge

Swimming at the Red Bridge

Me taking a quick swim at the Red Bridge in Knysna. The water was great and we found some otter tracks leading off into the bushes.

I did see some branches sticking out of the water under the bridge which means that there are trees wedged in down there. Quite a frightening sight considering I have often jumped off into that water. Imagine jumping off and landing on a fat branch!
