My female N.singalana is blooming again and I'd like to get some N.singalana pollen for her. Will also consider offers of pollen from other species that may produce some interesting hybrids. Standard 50/50 split on all resulting seed pods.
I just pulled the leaves off the main stalk, trying to get as much of the white connective basal tissue as possible. Then I just stuck them in moist vermiculite in small peat pots under humidity domes. Newer leaves work best.
Going by the 1st photo in the post I see 2 D.intermedia, one at 2:00 and one at 5:00. I also see what appears to be D.capillaris at 6:00. I'm not seeing anything that resembles D.rotundifolia in that pot.
You'll need to post a photo. Sounds like there might be a combo of things going on here, possible fungus gnats and either sow bugs or springtails (not all springtails are white and not all springtails jump). In any event, a photo will still be helpful.
There are forms of D.binata are indeed temperate. Many of them grow in very temperate areas of South Australia, Tasmania and New Zealand. I grow a small red form of D.binata binata and D.binata dichotoma "Giant' outside year round here in Boston.
