Fireworks

Well, the end of the Chinese Spring Festival (New Year holiday) sure puts Guy Fawkes night to shame! In the week I have been here firecrackers have been everywhere, but this evening the really big guns came out. For an full hour and a half (and maybe a bit longer) spectacular fireworks went off in a park by the Hainan Government buildings near Century Bridge - it is obvious these are a Chinese invention. Several hours later I still hear booms and bangs from all directions - it will go on all night. This is really ending things with a bang!

Hainan University

The solanums of Hainan are still awaiting us; we ended up staying in Haikou as the park we were going to was closed for the holiday. So we spent the day in the herbarium of Hainan University instead. The collection is tiny, eaten by insects and kept in a very poor condition, but what the botanists lack in facilities they make up in enthusiasm. We were treated very kindly by Professor Yang; it was a real pleasure to have the day in town - something I usually would never say! Tomorrow we head for the mountains in the centre of the island, one of the few places native vegetation remains.

From Nanning we went north (backwards!) to try to find a locality where an old collection of Solanum macaonense, an enigmatic aubergine relative, had been collected. We failed in that, but did find Solanum torvum (pea eggplant commonly used in Thai cooking) growing in the rubbish dump of Gansu – solanums often grow in the most unsalubrious places!

Near Gansu there was ample evidence of the threats to these beautiful and biologically interesting limestone hills – mining for stone and gravel is all but destroying many of them, by next year these will be completely gone, along with the endemic flora that grows there.

We carried on, passing fields with many people working to prepare for planting, harvesting sugarcane and manioc. Manioc is grown as a starch crop here, where I know it better in South America it is a staple food crop. My companions were surprised at this and asked an elderly man if they ever ate it - he replied something like only if we have to! It is amazing that fields of such extent are all prepared, fertilized and planted by hand, and ploughed by water buffalo.

Solanum violaceum                                                                      Collecting Solanum violaceum

We went to look at the base of some cliffs, found a cave tomb with the deceased in a jar so he/she could be moved if necessary and in the brush found our first exciting solanum – Solanum violaceum. This is a common species, but I am interested in comparing it carefully throughout its range to other species that may or may not be the same.

Field in rocks                                                                                         Polytunnels

Turning south off the main road to head for the Jing Xi, a town near the Vietnamese border, we went through a region of extensive banana cultivation, where many of the crops were being grown as seedlings in polytunnels – the fields looked white striped. This is not only to increase the heat, but to save water – we saw a man with a funnel and a bucket watering each seedling in the tunnel by hand. There has been a severe drought in this region this year – it shows.

Near Long Ho

We then crossed some spectacular limestone mountains, where the Long Ha Nature Reserve is said to be home to monkeys. In these mountains every square inch of cultivatable land is cultivated – between rocks and in spectacular terraces in all the valleys (like near Naling, where the rice paddies were being readied for planting and followed the contours of the land beautifully).
