One of my Cyathea expected to be either C.browni or C.cooperi. At least I believed I ID'ed and collected spores from the species. It looks unlike both. Here the pictures: |

Hi Alex, resembles a brownii hybrid [ brownii / cooperi] , I already Saw many copies that looked like this here and seen by other growers! Difficult to determine correctly Eduard. |

Hybrids between tree ferns species seem to be very rare and few have been discribed. I therefore don't think there is a good reason to think this might be a hybrid. Cooperi is so variable. |

I have heard that research has been done, the brownii's that I raised here [brownii var.] has brownii and cooperi genes . Eduard. |

I would go with C.brownii. Funny that here in the states its never sold at nurseries. You have to internet order it. C.cooperi is sold everywhere. |

The most remarkable property of the "hybrid" is the extremely fast maturation. The "spore-to-spore" time was just 25month! Two other spore samples, I presume C.coopery and C.browni, were seeded simultaneously. C.coopery become fertile a year after the "hybrid", whereas C.browni 7 years on still has no spores. The "hybrid" spores are viable and fast to produce protallys. I would expect some fertility issues from a hybid. C.marcescens is well known example. Still Eduard's hypothesis has a good chance as I had C.coopery and C.browni specimens sids-by-side when early protallys were replanted in one "sporelining" box. Here: three bottom rows are Cyathea leichardtiana, Cyathea brownii and Cyathea cooperi. On the other hand the plants are "C.cooperi", "C.browni" or "C.mistery" only in my opinion. I hope you will agree with me on the first two at least. Early days when I collected spores in RBG Melbourne I labelled them "cooperi" or "browni" almost randomly. As result I used spores from these three plants (below) and later randomly peaked few sporelins from every germline. So they all are of nameless descent. |
