WebEcoist has a nice series of slideshows on “70 Extremely Exotic Plants, Flowers, Forests & Trees.” Kinda silly, I know, but I’m a sucker for photos of weird plants, I guess. Anyway, the one on “Deliciously Exotic Plants, Fruits and Vegetables” puzzled me for a minute because the picture labelled “pawpaw” is certainly no Carica papaya. In my ignorance, I thought the term pawpaw was only ever used as a synonym for papaya. Well, it turns out the fruit in the picture is also called Hoosier banana, and is in fact Asimina triloba. Related to the cherimoya (Annona cherimola), “[t]he pawpaw is native to the temperate woodlands of the eastern U.S. The American Indian is credited with spreading the pawpaw across the eastern U.S. to eastern Kansas and Texas, and from the Great Lakes almost to the Gulf.” There’s a festival devoted to the fruit in Ohio in September. Interestingly, if you search Wikipedia for pawpaw, it sends you straight to Asimina. A Google search also returns mainly Asimina stuff, but if you search images you get a mixture of Carica and Asimina. The dangers of using common names.

Sea buckthorn becoming a success in a land with no sea
The name of the game in Mongolian agriculture is diversification. And one of the things researchers at PSARTI, the Plant Science Research and Training Institute in Darkhan, and others are looking at is a shrubby berry called sea buckthorn (Hippophae rhamnoides) with some interesting nutritional properties. They have put together a small germplasm collection of local and introduced material and are doing agronomic trials of various kinds, trying to find the best varieties for different purposes. In fact, the plant has a pretty long and rich history in Mongolia:
It is said that Genghis Khan, the Mongol conqueror, who established one of the largest empires from China to Eastern Europe in the 13th century, relied on three treasures: well organized armies, strict discipline and Seabuckthorn. Seabuckthorn berries and seed oil made Genghis Khan’s soldiers stronger than his enemies.
There are already some products on the market. Like this delicious icecream, called Ice Doctor.
The natural history museum in downtown Ulaanbaatar has a display featuring a number of locally-made products — a couple of different oils and “globules” — along with a somewhat threadbare diorama.
I guess commercialization still has some way to go, but a start has been made. Another wild species with some commercial potential may be strawberries.
Wild Allium of various kinds is also sold in the market.

The ups and downs of trees
I’m really not sure how good an idea it is, but this “Great Green Wall of Africa” that people are talking about will certainly be a sight to see. And a bit of a food resource too if the indicative list of the species that will be used is anything to go by. While I was wondering whether to write about this, four other tree-related stories popped up in my feed reader, which convinced me. So apparently “between 1980 and 1997 England saw a 64% drop in trees,” which sounds pretty incredible, but is probably nothing compared to what is going on in southern Congo. On the plus side, Argentina seem to be building its own green wall down south. Although there’s nothing in the press piece about what species will be used. And finally, in Liberia, old rubber trees are being uprooted and recycled, hopefully as a prelude to replanting something.
LATER: And another, from Tasmania.
