Everything that smells great and is beautiful is not always good!
Imagine a beautiful plant that lures insects to their death by a sweet smell. And to top it off, the pitcher plant then proceeds to eat its victim!(That's the whole point of catching it!)
It has a pitcher-like shape that features a deep cavity filled with liquid.The sides of the pitcher are slippery and are grooved in such a way so as to ensure that the insects cannot climb out!Insects are attracted visually or by odour!( Sometimes the pitcher plants multi-task too!)Once the insect falls into the pitcher like body,that's the last thing it would have ever do.The small bodies of liquid contained within the pitcher traps, do three things to the insect:-
(It's okay, put that hand-kerchief away, even I felt sad at first)
This may occur by bac(the bacteria being washed by rainfall) or by the enzymes of the plant itself.The insect then becomes a soup of amino, phosphorus,peptides, and other minerals.(Okay, okay, it doesn't sound tasty).This soup is what the pitcher absorbs for its food and nutrition.
Like all insectivorous plants, they occur in locations where the soil is too poor in minerals and highly acidic.Most other plants could not survive in such soil conditions but the pitcher plant does because it gets its nutrition from outside sources(C,mon I want to say poor little insects in a decent way).
There is a Welwitschia mirabilis Hook.f. "grove", if those things can form a grove, East of Swakopmund Namibia that have never reproduced since they were found.. Needless to say there are lots of explanations of how they got there to start with.
It is fairly easy to verify the no reproduction thing - they make "cone" fruits that hang around for long time. And no, it isn't an Edgar Allen Poe graveside flowers kind of mystery where you have to invoke parties unseen who come in and swoop up the "cones".
Of course, the best explanation is that aliens planted them there - just ask Erik Von Donniken IF you ever get a chance to see one you'd think it came from Mars anyway.
oddball #2 Aldrovanda vesiculosa L. the waterwheel plant. It is aquatic, captures small swimmers like Daphnia and then digests them. It is my fave 'carnivorous' plant. http://www.sarracenia.com/faq/faq5045.html
