plant what purple flower pepper is this

After I was given some wonderful hot bell shaped red peppers (origin Argentina?), I dried out the seeds ( black) and struck three plants.  
the flower is my profile.
the stalks turn purple and as does the joins of branches.
 
I am interested in two things:
1/what would the pepper be - how do I even start to identify it ? 
2/and my problem is the flowers just seem to fall off - no fruit emerge - although this is probbaly best raised in a different forum.  
 
perhaps though I'll start with.... what pepper is this?
 
thank you for any assistance

How hot is the plants' environment?
 
_____
we live in a temperate environment and can have extremes in two days - 40 degrees one day, 20 the next , showers and extreme cold the next....
 
looking at forums today - I have also tried assisting with polllination - so we'll see how that changes things - I've done this on one plant only as a bit of an experiment.

Maybe a Locoto? Definitely a C. pubescens, pretty sure they are the only ones with black seeds. Is it fuzzy too?
by fuzzy do you mean the seeds or the plant
plant definately has fuzz - leaves, stalks, even flower buds
 
thanks

There are more than a few black seeded species.

Rocoto sounds like the pepper we are looking at here there a ton of different variants of rocoto though
 
The flower is very typical of C.pubescens and what you describe is also typical of C.pubescens. 
 
Yes, they can be quite hot and very tasty. South american pubescens varieties are usually called Rocotos, occasionally Locotos. There are hundreds of them, most without a specific name. They tend to be Peruvian Rotoco, Large Rocoto, Long Rocoto etc 
 
Most pubescens do not like heat. It it gets above around 85°F for any length of time, the flower fall off and you get no fruit. 
 
Agree - everything you've said indicates some type of pubescens. And as Nigel said, they don't like heat. Typically in the heat of the summer they will bloom profusely and drop all the flowers, unless you have some means of shading them. Even then, though, you may not get any or much production. However, once the temps cool off you should see them start producing. I always manage to have to bring mine inside the house or I would never get any ripe pods, as our season here is too short.
 
Okay .. my two questions solved
 
thankyou everyone for responding 
based on info -   I will probably transfer the plant in autumn to a pot so that I can move it out of potential frost.in our winter / spring 
40 degree day in Oz is like 104 oF ... at least then I can find it more shade ...
 
cheers!

in looking at the http://thechileman.org database - good resource thanks for the cross reference from another post
 
it struck me that the number of petals / stamen vary 
 
mine has got 5  and most of the C.pubescens are either 6 or 7 
can this help to further identify the species
 
thanks
 
Yup...its a pube!!! Congrats great plant! Geeme is spot on with the shade. I grow them in heat similar to yours and can get them to set. They also will continue to drop most of their flowers (hundreds of them) until they've grown into their environment. For example, if you planted one in a 5# nursery container it would grow to maybe a meter and if weather was good start setting pods. If you prep a nice deep in-ground spot or put it in a large container it will grow until it's reached it's potential to that site before setting (many) pods...and then only if weather permits. Once they start to set...they'll set a bunch. Very typical, and nothing to worry about too much, but very frustrating. When mine finally set the first pod or two I take the time to use a small artist brush to hand pollinate them. One of my favorite plants and pods. In an 18# container they will grow to over 2 meters tall and 2.5-3 meters wide.
 
Good Luck!!!
