One of the three chile varieties from Guyana growing here needs some introduction.  It is an attractive C. chinense with round fruits like small cherries on a low spreading plant with small leaves.  I think it's potentially one of the most ornamental chiles:

The original collector's records called it "Marawiri", which remained a bit of a mystery, but I read that "meri wiri" or "mari wiri" are used in Guyana for the variety (or varieties) also called "wiri wiri".   However, this variety seems closer to plants called "Bod'e" than "wiri-wiri", or at least than to the one "wiri-wiri" variety I now have from a different source.

"Mariwiri" has pale-colored anthers [unusual in C. chinense].  Unlike it, the fruits of this one are on erect stalks:

I thought it might be interesting to cross it as a primitive chinense with the somewhat similar C. chinense "Wild Brazil".

"Mariwiri" and "Wild Brazil" fruit comparison:

"Wild Brazil X Mariwiri" F1 plant

Hybrid fruit comparision [I didn't grow any "Mariwiri" in 2009]

I also crossed "Mariwiri" with "Duke Pequin", which made an intermediate-sized plant:

Fruits ripen red.

New 2009 crosses growing this season:
Duke Pequin X Wild Brazil
Duke Pequin X Wiri Wiri [the latter seems more like C. frutescens than C. chinense to me]

Duke Pequin X Pimenta da Neyde 
Trinidad Scorpion X Pimenta da Neyde

It appears that the purple coloration may be a dominant trait-- so far, F1 seedlings of both these crosses are coming up just as pigmented as Pimenta da Neyde seedlings!

Fatalii X Bhut Jolokia
Trinidad Scorpion X Bhut Jolokia  [I suppose these might count as "weapons of mass destruction"]
