I just got a message from the Derek Spicer who's the chairman of the British Conifer Society.
He told me that Lawrie Springate died last Thursday morning probably from a heart attack in his sleep.
Lawrie was a plant registar for the Royal Hortical Society (R.H.S.) and was busy at this moment with a follow up for the World Checklist of Conifers in which I helped him a lot with writing conifers names in a good way and the discriptions of these.
He will be a huge loss for the Britisch Conifer Society and for the registrated plants world.
Stephen, maybe you can add some more...
