So I decided I'm going to propagate this elusive liverwort, to see if it can be done. To test my mettle. For the colony! Radula Marginata is a liverwort, a member of the class of bryophytes (plants that lack lignin-containing vascular tissue, this is more of a morphological relation than a genetic one). In terms of reproduction, at this stage I'm just interested in asexual reproduction: http://www.anbg.gov.au/bryophyte/vegetative-reproduction.html This thread is for all advice and questions too. I'm just putting it up as a template for now. Reproduction Radula Marginata is probably dioecous (having both male and female parts to reproduce sexually). Radula Marginata has a perianth. http://rsnz.natlib.govt.nz/volume/rsnz_74/rsnz_74_03_003750.pdf In liverworts (Marchantiophyta), the perianth is the sterile tubelike tissue that surrounds the female reproductive structure (or developing sporophyte). Many liverworts reproduce through gemmae: The production of gemmae is a widespread means of asexual reproduction in both liverworts and mosses. In liverworts such as Marchantia, the flattened plant body or thallus is a haploid gametophyte with gemma cups scattered about its upper surface. The gemma cups are cup-like structures containing gemmae. The gemmae are small discs of haploid tissue, and they directly give rise to new gametophytes. They are dispersed from gemma cups by rainfall. http://en.wikipedia.org/wiki/Gemma_%28botany%29 Radula Marginata is not known produce gemmae I believe. A related class of liverworts does sometimes, and they are the same shape as the leaves apparently: http://books.google.co.nz/books?id=kQ8bAQAAMAAJ&pg=PA31&lpg=PA31&dq=jungermannia+gemmae&source=bl&ots=sS1SYFL26Q&sig=V2xZQI0rxg8MZElyTKuj0_FgMAI&hl=en&sa=X&ei=n3vKUeKwBsr-lAWlgIGoDw&ved=0CCkQ6AEwAA#v=onepage&q=jungermannia%20gemmae&f=false This liverwort (Riccia sp.) reproduces asexually without the usage of gemmae: Cultivation Unfortunately nobody seems to have had much hand at cultivating this guy. I'm thinking that a moss (moss are bryophytes) technique with modification would be applicable. I have read a few moss tutorials. This type of technique would be ideal. I would love to figure out if RM can be cultivated this way too, or if not why not: http://gardening.about.com/od/gardendesign/qt/How-To-Grow-Moss.htm I'm thinking that moss is a lot more hardy, while Radula is not. It's found in very shady areas, and the dark green of it suggests so (as a rule of thumb, the darker green a leafy plant, the more shade it prefers). I think that a fogger would be an ideal way to keep the humidity levels under control. I found this: http://www.hollywoodfishfarm.co.nz/detail/view/reptile-one-terrarium-fogger/m/1050/ Some research will determine if it's a good way to go. Some research has just been completed, and I've determined that a piezo fogger will not be a substitute for misting. I want to find/make an automatic misting system so I can just leave the tank alone. Bah - I had really hoped that a fogger would work. I'm thinking to run: 1) Misting system (runs on a timer, so twice a day or so, a fine mist sprays every surface 2) An air-transfer system that forces the tanks air to partially evacuate for a few seconds every half hour or so (two computer fans [intake and exhaust fan] built into the lid should do it). The air going stagnant will probably be a quick end to any experiment with this Radula I imagine (I might try some in an enclosed tank anyway to see if it can handle it). Might need to make up a controller using raspberryPy or whatever the kids use instead of PIC chips these days.
