I found this interesting information on bakuri propagation in: “Fruit Trees and Useful Plants in Amazonian Life” published by FAO/CIFOR and PPI 2011

"If bacuri does not grow in your area on its own, you can plant it. You can do this in one of two ways: by planting the seeds, which take two years to germinate, or by planting grafts and sprouts that produce earlier. A good way to get sprouts quickly and cheaply is to plant a seed and wait 70 days for the roots to grow. Then cut the seed and leave the root in the ground. From the severed root, after two months, a small yellow sprout will grow, which requires a few more months to develop. You must wait about four or five months until the sprout reaches about 40 cm and is ready to be transplanted. A seed with a small piece of root can be used to form new sprouts. Just repeat the process. From one seed it is possible to obtain three or four sprouts. The recommended space for this planting is 10 x 10 m, reaching up to 115 plants/ha. Using this method you can have sprouts ready in less than one year."

Second the comment on hexane, a known carcinogen. You might try extraction after grinding the kernels with acetone , methanol or ethanol. These solvents have very low boiling points and are easily removed under vacuum or with gentle heat, or a combination of these. The human body generates small amounts of acetone as a by product of metabolism; likewise with ethanol. Methanol is somewhat more toxic but again is easily and completely removed.

Hope this helps. Good luck on your project. If you need any more help, i would be happy to assist in exchange for a trip to your farm for a couple of weeks! LOL

A. obovata is listed as edible: http://www.fnps.org/plants/plant/asimina-obovata

As Tropheus78 mentioned, I would plan for ponds, and swales/runoff control in general. That part of the Big Island can get some amazing rainstorms and you don't want that nice deep soil to wash away. Plus ponds open up the possibility for aquaculture and some nice edible aquatic plants (taro, water chestnut, lotus, Trapa etc.) I would suggest that you start from your homesite and plant outwards. I would also suggest that you plant your windbreak plantings ASAP to give them a headstart over your fruit trees. Bamboos are the fastest; get in touch with the folks at Quindembo Bamboo Nursery near Waimea. They can advise you on species selection, best edible species etc. You've got lots of room, have fun and go nuts. Oh, and post lots of pictures!

As far as the nomenclature, the correct spelling is Psidium guineense Sw.

P.guianensis and P. guianense are common mis-spellings, and are not valid names. However, there is a valid species, Psidium guyanense Pers. (Just to confuse things further LOL)

From the photo of the immature plant, I also believe that what you have may not be Psidium guineese.

Hope this helps.

I believe that the Edgehill variety was developed in the 60's-70's by CRFG founder Paul Thompson and was said to be one of his best selections.

If you get to Ethiopia a priority species to track down would be Cordeuxia edulis, called the yeheb nut. It's endemic to the Horn of Africa and classed as endangered. A leguminous shrub with as very deep taproot, it produces a seed that is said to rival macadamias. Very short viability, and so it has never been brought out of the region, except for an effort by Israel in the 70's I believe.

Can you tell us what the fruit tastes like? Thanks.

 Just curious if you got your seeds and if either species germinated?  have seen some interesting species from them but are a bit leery of ordering from a reseller.

Just saw three species for sale on rarepalmseeds.com...betacea, abutiloides and hartwegii.

You might check with this outfit:

http://www.awmpalms.com/

They ship tissue cultured date palms around the world. Didn't see a variety list on their site, so I don' know if they have Al Naghal, but they might be able to point you in the right direction. Good luck!

 You could contact conservation group this group for Sonneratia:http://www.mangrovewatch.org.au/

Araucaria bidwillii can be gotten from Rare Palm Seeds: www.rarepalmseeds.com

I think the Lepisanthes has been offered by a couple of the Indonesian members of this forum, maryoto IIRC. Ditto for Mangifera pajang, Diospyros discolor, Stelechocarpus, Baccaurea, Garcinia,...check the Buy/Sell board
Vitex doniana can be ordered from Silverhill seeds in South Africa. You may have to wait for them to collect it; I know they have offered it in the past.

Hylandia is endangered and is strictly controlled by the Austarlian Gov't; basicall unavailable unless you are a bona fide Botanical Garden.

Xanthoceras from J.L. Hudson: http://www.jlhudsonseeds.net/

The Brazilian and South American species (Campomanesia,Myrciaria, Eugenia leitonia) have been offered by members of this forum from those countries in the Buy/Sell section from time to time.

Good growing

   " ....the only plant found on this planet to contain Chalcones."

Actually this is incorrect. Chalcones (a subset of the flavanoids, which are ubiquitous in higher plants) are widely distributed in nature, particularly in the Asteraceae, Leguminosae and Moraceae.

They are indeed highly bioactive compounds, whatever their source.
