I have tried to ID this plant before , but with some better pictures and more info may have more luck now . Seed/seedlings? of this were given out to many of the people attending a show organised by David Burnett [author of 'Cultivated Alocasia' edition of Aroideana ] that was held in Townsville about 20 years ago . It is very similar to crispimarginatum , and has a more upright habit than plowmanii . Very tough , as it will grow in full sun . I just happened to get very close to a flower and noticed the putrid odour and the flies hanging around .
