Tropical Fruit Discussion / Re: Do Persimmons Ever Get Soft?
« on: October 02, 2019, 03:10:47 PM »
what species, american persimmon? asian persimmon?

Pick them hard, is super convenient. They will get mushy and sweet at home. You can dry them also, and they are very good  at this state (like a mix between a date and a fig). I dry them at the chimney for Christmas and I'm very fond of them

Fits perfect  :) :)

Those fruits aren't edible therefore. Dry leaves in LOW quantities and cooked are edible as spices. Poisonous instead. Beautiful tree in any case.

Or use gnu-linux instead in an older computer, save money, and your definition of fast computer will change forever...

Maybe will not boot in 5 seconds, but if correctly configured will run pretty quick, is very safe, and nobody will collect your data on everything that you open and do with your machine.

Hum, I don't know, is puzzling, with a mix of several things... what about bark or flowers? How is the inside part of the fruit?

Are the leaves compound with more than 5 folioles?

I would say Annonacea but not necessarily Asimina (could be cherimola also) but must admit that Diospyros is a good candidate also.

Leaves are a little short, but nothing prevents it being Asimina IMO

Looks like a climber from Bignoniaceae family, (or maybe a Fabaceae)

Datura. Even goats avoid it (and goats eat everything sligthly edible)

Has killed people trying to use their "medicinal" properties before, so pull up or leave it alone for its nice flowers, but don' t mess with it.

Looks like a (broom?) branch trying to pretend to be a tree in a manipulated photo.

Tropical Fruit Discussion / Re: Fire in the Amazon...

Fire is a natural and necessary part of land management 

Hem,... not.

Fires created by man after chopping trees in a rainforest are definitely criminal, not natural, Rainforest is a biocenose in a relatively fire proof state because... well... it rains each day. Old forests tend to make its own rain,

As management,, changing tons of mangoes, durians and figs, by, duh... cinder and soy, is outrageously stupid.

In a school and huge, probably the result of a biology class. Some children playing with seeds

You will never obtain a single cucumber from that plant

An increasing problem in Europe...

In my experiencie they are prone to lose leaves in container when they get neglected and too dry. Put it in soil (if your climate is right) and the problem will probably end. If not,check for die-back in too soggy soils

Yummysome!.

 I wonder how most of this things would taste. Maybe some day.

And now for something different:

I have one but is too far from you and is still small. An easy to grow and sun loving shrub.

Tropical Fruit Discussion / Re: Africanized bees in Costa Rica
« on: August 05, 2019, 02:29:57 AM »
If you have a problem with africanised bees, you will love Asian Hornets in Europe. They can kill you faster than bees of course, but will munch bees also. Available in warmer areas of Romania in a few years, probably.

In Costa Rica Phoneutria would be a major concern for me. And Lonomia also. Mosquitoes.Kissing bugs spreading Chagas disease...

Cold Hardy Citrus / Re: Suspicious Plants

Finger comb the rootball gently, put it in a rich organic soil with lots of old manure, add water, and will be happy in no time.

Not necessarily greening disease. Look like rooted scions cultured in a soil that at this point could be depleted. Could be a deficience in Molybdenum, Zinc or Nitrogen also, for example.

Tropical Fruit Discussion / Re: illicium verum vs. illicium anisatum
« on: July 26, 2019, 07:47:07 AM »
Thank you for asking such interesting question. Those are fascinating collector plants and I'm learning a lot

I have find one clue that really could help. Illicium verum smells typically like anise. It seems that Illicium anisatum does smell more like sassafras three or bay laurel instead.

There is also the possibility of having another species of Illicium. Those with red or pink flowers can be easily eliminated from the list, and american subgroup parviflora should had small (or scarce) flowers, but other asian species with white flowers should be checked also. Can you post pictures of flowers, fruits or leaves from your plant?

Fruit shape looks different also to me (see fig 1.2) a little more plump, but assure you to check it. Is just an opinion based in a photo and I could be missing some specific variation

Morphologically there are some clues also. Both species had seeds of 7-8mm long. Anisatum up to 8.1, verum up to 8.8 mm. Anisatum can have slightly ticker seeds but the value overlaps extensively.

Seeds have a narrow eliptical scar in the conection with the fruit called hilum (hilum is engraved in the basal part of the seed). In one extreme of the concave hilum lies a convexe pimple/excrecence called strophiole. Strophiole is more or less rectangular in verum (the rectangle is arranged perpendicular to the hilum), but hemispherical (round) in anisatum

The real problem is when a product based in verum, is adulterated in part with the much cheaper anisatum. This is a serious problem that should be handed by professionals. Only a chemical analysis can identify it.

If you see many hexagonal calcium oxalate microcrystals under a microscope is a red flag of presence of anisatum (but not a guaranteed presence). Beware also that the lack of hexagonal crystals does not guarantee absence of poisonous anisatum in the product. You need a really good microscope to see it clearly, SEM is better, and is a really expensive machine.

Epidermis of seed is said to show a red fluorescence in verum (yellow in anisatum). Endospermum is said to show a blue fluorescence in verum (brown in anisatum). You need specialized lab stuff to see it and this patterns does not occur always so is not a reliable character.

There are differences in striation of cuticle and in shape and size of some specialized cells but they overlap extensively in both species. Unreliable

In resume: if you have the entire seeds the presence of 'big' astrosclereids in the columela tissue are the only reliable character. Branched microsclereids (astrosclereids) over 350 micrometers large is characteristic of verum. If you have a powder made of Illicium, only a chemical analysis can help you.
