I'm sorry Swords,but I have to do it again. I thought mistletoe was a fungus so I asked in my biology II class. Mistletoe is an epiphyte like orchids and not a parisite. Atleast thats occording to my Bio professor. Some people think orchids are parasites, but that is untrue too. I don't know about Rafflesia so I can;t say about that. I would think though that its not a parasitic relationship, but a symbiotic relationship. Does it kill the Tetrastigma vine? Or just live with it? If it kills it then its not giving back, but it it doesn;t kill it then its a symbiotic relationship. A give and take relationship. Because the microriza you talk about , the fungal mycelium, is not paresitic either. It gets the sugars from the root systems of other plants in echange for increasing the surface area for nutrient pickup for the plant its sharing the symbiotic relationship with. Just remember to be parasitic it must not give back, but just consume off the host plant. If it does give back like with the funus normaly giving extra surface area for nutrient pickup, then its a symbiotic relationship and they can live like that forever. Parasitic relationships only last long enough for the host to die then the parisite moves on. Licen are an example of a symbiotic relationship. It has a fungal and algea component. The Algea component does photosynthesis while the fungal part is like the root system persay and the body. They are the only thing in nature that decomposes rock besides the wind wear. Very cool thing.
The Titanum, once reaching flowering size, bloom one year then put off a vegitative growth the next, and it alternates there after. Atleast thats what I read about "Mr Stinky" at one of the big botanical gardens. Then the bloom only lasts a vew days too with only one or two days being really stinky. Definatly not an indoor plants, even if you did have 12 foot ceilings.
