Bryological visitors at the Gardens

On Thursday the 28th September, we welcomed Professors Takayuki Kohchi and Ryuichi Nishihama, from Kyoto University, Japan, to the Botanics. Professor Kohchi’s lab is renowned for their evolutionary…

What’s the story when there’s no variation?

Enigmatic and isolated although it is, it seems that our Australian colleagues have now “got their eye in” for complex thalloid liverwort Monocarpus sphaerocarpus – after many years…

DNA identification of Long’s Long’s Marchantia

Many new species are already included in natural history collections around the world, it’s just that nobody has yet got around to examining the material, recognising that it represents something…

Long’s Marchantia

Formerly the head of our Cryptogam section, and currently an extremely active RBGE Research Associate, David Long is well known and respected for his botanical work in the…

A phylogeny of Sphaerocarpos

In conjunction with Dr Daniela Schill’s monographic work on Sphaerocarpos, we’ve been building a molecular phylogeny for the genus. We have attempted to extract DNA from 66 accessions,…

Sphaerocarpos, preview to a monograph

The Sphaerocarpales (or “Bottle Liverworts”) form a very distinct group in the complex thalloid liverworts, with ca. 30 species in five genera: originally the group just included Geothallus…

A rapid phylogeny of Marchantia, from the RBGE collections. I. Sampling

Not long ago, the only non-crop plant that the mainstream scientific community seemed to be aware of was the brassica Arabidopsis thaliana – easily cultivated, with a short…

Impressions of a workshop: New model systems for early land plant evolution, 22 – 24 June 2016, Vienna, Austria

A couple of weeks ago I spent a few days in Vienna, my first visit in 11 years, when I was last over for the 2005 XVII International…

The complex thalloid liverwort Aitchisoniella, and its place in the tree of life

The genus Aitchisoniella contains a single species, A. himalayensis, which was described by Pakistani botanist Professor Shiv Ram Kashyap from plants that he collected in Mussoorie, Uttarakhand, India…

There’s more to Marchantia than there used to be! An introduction to the new additions

One of the most recognisable groups in the bryophytes, the complex thalloid liverwort genus Marchantia, has just become a bit larger. We have sunk Preissia and Bucegia into…

Lost before found: Was there more than one species in Monocarpus?

The complex thalloid liverwort Monocarpus sphaerocarpus has been found on two continents, Australia and Africa, separated by around 8,000 km of mostly ocean. The green plants themselves are…

Rates of change in liverwort genes

Although the exact relationships between the earliest land plant lineages are not yet well resolved, there is consensus that liverworts are one of the most ancient land plant…

Oh blast – there’s more to life than Marchantia polymorpha

One of the earliest plastid genomes to be sequenced, in the late 1980s (Ohyama et al.), was that of Marchantia polymorpha, one of the commonest liverworts around town,…

Scientific progress, continental drift and glaciers: The history of a paper on the complex thalloid liverworts

Rather a while ago, back in 2003, we started working on a phylogeny of the complex thalloid liverworts at the Royal Botanic Garden Edinburgh (as a Molecular Phylogenetics…

Finding Monocarpus, in the herbarium

At the Royal Botanic Garden Edinburgh we’ve been working on the phylogeny of the complex thalloid liverworts for rather a while now. David Long presented a poster on…

On Monocarpus

As far as liverworts go, Monocarpus is a rather strange plant. It’s very small, in itself not that unusual for a bryophyte, but rather problematic if you need…

Biology, genomics and evolution of the complex thalloids

Twenty-five participants from 13 countries have just attended a symposium on complex thalloid liverworts in Edinburgh #Marchantia2015. The meeting also included two teleconferences (from Australia, John Bowman, Monash…

RBGE Complex Thalloid Liverwort Symposium, July 14th-15th 2015

The complex thalloid liverworts, or Marchantiopsida, are one of the oldest land plant lineages, and contain a bewildering array of morphologies, ranging from comparatively simple plants like Blasia,…
