Reading the experience of others growing this sp. I have thought it might be an idea to work out if we're all growing the same thing. I have two reliably identified strains with marked differences.
These seeds are the strain on which all my sucessful work has been based.
They appear to be identical to
these seeds in a thread over at SAB.
These seeds were obtained from the same supplier a couple of years down the line.
Note how they are nearly twice the size of the above seeds.
They closely resemble the picture up at Entheopedia.
http://entheopedia.org/?action=Photos&id=41Grown out, notice how they are superficially similar yet somewhat shorter and with a noticable gloss to the leaves. They also come to maturity two or three weeks earlier than the above ones and in a more staggered way. I found them to be useless for our purposes; putting out very little in the way of useable foliage and upon extraction, via my chlorophyll precipitation tek, yielding little more than smears with an indole smell.
I contacted my supplier, obviously unable to mention the assay I had made of the plants. He replied:
Quote:This is very interesting. I have looked at the images you have sent and firstly I am confident that you are growing Brachystasis.
Now things get a bit more complex. This species is a weed species and appears in the US Europe and Asia. The general taxonomy is narrow and well defined, all the plants exhibit a classic flowering head and general leaf shape and structure is constant within the description of the species. Having said that this (and most other) weed species exhibit a wide range of local biotype differences, these can be expressed as early germination, more or less waxy leaves, shortened or extended flowering period and so on. These are clearly evolutionary adaptations based on regional conditions – season length moisture, availability being the key factors in flowering timing.
We have grown many species from multiple sources over the years and have seen a wide range of physical differences so much so that we have described each biotype characteristics to allow the clients to decide on the appropriate type.
I have some colleagues who specialise in grass weeds so I will pass on this case for some further input
It’s a very interesting example of how plants keep you on your toes !
When growing out a small sample of the new seeds, of which I was very cautious, I was carefull to cull before flowering proper to prevent cross-pollinisation; however, a little occured anyhow. I was quite surprised to find a seed head of the top strain containing
both the smaller and large seed type, kind of confirming the rather different plants to be closely linked.
The small seed variety as well as reliably producing useful quantities of alkaloids also respond very well to a culivation regime. Pots for extraction foliage and patch sown plants reliably produce useful amounts of viable seed.
I would be very interested to see what other people have got and are growing under the name Brachystasis.
