  Re: [Aroid-l] Fiction of bullate leaves

Hmm. Maybe we can infer that a bullated leaf has evolved so that at least a portion of each leaf surface is oriented toward the light source in a way that it is achieving maximum photosynthesis? Just a speculation. In my aroids, nearly everything I grow is a swamp plant or a shallow water species (mainly Cryptocoryne). Since there are bullated species and smooth species, it is probably not an effect of humidity. Or maybe bullation serves to passively collect detritus, so as to provide some nutrients? As they say, a single fool can ask more questions than a thousand wise men (or women) can answer.

I'll see if I can locate a copy of your suggested book.
