A Japanese banana in northern Italy

An advert in a local gardening magazine for something called Freddi Banana, supposedly a cold-tolerant banana “developed” in the northern Italian region of Alto Adige, led me down some interesting online byways. In one place it is a cross between a Japanese and a Nepalese variety, in another its origin is given as Ryukyu Islands, Japan. That’s the chain stretching from Taiwan to Japan. I found the whole thing hard to believe, but a little research revealed that there is indeed a Musa species in the Ryukyu Islands. This is Musa basjoo, and it is the most cold-hardy of bananas. Various cultivars are available commercially.

Musa basjoo is commonly referred to as the Japanese Fibre Banana and it’s native place is given as the Ryukyu (Liu Kiu) Islands. However, Musa basjoo is not the Japanese Fibre Banana. Musa basjoo is not from the Liu Kiu Islands and not from Japan, it is a Chinese species.

So what is the Japanese Fibre Banana, I hear you ask?

The true identity of the Japanese Fibre Banana became known only in the aftermath of Japan’s defeat in WWII when the Ryukyu Islands came under the control of the United States Civil Administration of the Ryukyu Islands (USCAR). USCAR brought to Okinawa Egbert H. Walker, a staff member of the Department of Botany, Smithsonian Institution who was in charge of the Serviceman’s Collecting Program (SCP) in which US forces members were encouraged to collect and submit botanical and other specimens. But Walker was no desk-bound administrator of the SCP. He was an accomplished field botanist and developed a thorough knowledge of the Ryukyu flora. His work, during which he personally collected over 7,000 plant specimens on Okinawa and neighbouring islands, culminated in his Flora of Okinawa (Walker 1976). Walker made no mention of M. basjoo in this work but did include the ito-basho, Musa liukiuensis, after the treatment of which he commented:

“Seeds from plants [of Musa liukiuensis] in Oku [village in northern Okinawa] were grown in Kingston, Jamaica by the Banana Breeding Scheme of the Banana Board. The seed, seedlings and flowers were reported in 1973 to be identical with those of Musa balbisiana Colla.”

Called ito basho, or “thread banana,” the Japanese Fibre Banana is very important in Ryukyu tradition, much like abacá, a different fibre-producing Musa species, is in the Philippines.

In the old days, bolts of plain-colored, striped and kasuri (ikat) basho-fu were woven in numerous locations across the Ryukyu islands and were used as tribute payments to the Okinawan royalty. In those days, basho-fu was worn by everyone from kings to commoners. Nowadays, however, basho-fu is a luxury cloth that is made only in the village of Kijoka, on the island of Okinawa.

Millennium Seed Bank on the BBC

And also at the BBC, “Banking On Life.”

In this study of the history and future of seed banks across the world, Richard Scrase takes a look at the largest such store in the world, The Millennium Seed Bank in Sussex, as it takes in its billionth seed.

Although Svalbard gets a mention too. You can also listen to the programme here. Not clear if it is associated with the summer exhibition of the same name. Have we had enough about genebanks on the media of late, do you think?

No little houses on this prairie

I promised you more on the Doolittle Prairie, and here it is. But first, thanks to Candy Gardner for arranging the visit, and to Mark Widrlechner for leading the tour.

Doolittle Prairie State Preserve, near Story City in Iowa, is a small remnant of native tallgrass prairie. The 26-acre state-owned protected area supports about 220 plant species. 1 About half of the area, the northern part, has never been ploughed or grazed, though hay was cut until the 60s. The southern part has been grazed, and the southwest corner ploughed until 1965 and then replanted with seed from the northern section. All around are fields of maize and soybean. Management is by cutting and burning, to keep down exotics, and encroaching shrubs and trees.

It’s a very evocative place. You can just imagine the deer and the buffalo roaming on it back in the day. There are still deer. Buffalo, not so much. 2 It’s also pretty interesting from an agrobiodiversity perspective, because it’s got quite a number of crop wild relatives for such a small place.

A couple of species of wild sunflowers, for example. This one is Helianthus rigidus:

There are also native species of Allium, Elymus, Lactuca, Fragaria, Prunus, Ribes, Rubus, and Vitis:

All in a beautifully colorful setting, at least at this time of the year.

So, a bit of a CWR hotspot, in its own small way, and protected to boot. You may remember the recent global review of the role of protected areas in CWR conservation. I don’t think that CWR have been mapped in the US in the same way as has been done in Russia, however. 3 Once you have geo-referenced CWR locations, you could easily mash the result up with the online map of protected areas to see which national parks and reserves contribute most to CWR conservation. Anybody out there working on this? I bet little Doolittle Prairie would be on that list.
