Nepenthes truncata gets its name from the square ending of the leaf before the pitcher. It is native to all of the Philippines where it grows in the hilly areas close to sea level. Pitchers can reach 16″ long. A botanical garden in France recorded it eating a mouse. I’m told it loves to eat wasps.
I had been growing it under a fluorescent light and on a windowsill. It’s now in a very bright south western window and it appears to love the sun much more than my other Nepenthes. A grower in Italy reports it can handle highland temps, I’m not sure I’d risk trying it.
The first reference to it I could find was in the 1911 Pennsylvania Botanical Society meeting notes.
I found mine from a seller of test tube plants on eBay.
