The helenae we know for years ( the "yellow" helenae) is coming from Cao Bang, close to the Chinese border. There is a very good type of micranthum coming from there too.
The helenae delicatum comes from Tuyen Quang province. The plants as a whole are usually larger than the "yellow" Cao Bang type. Many have been exported to China. Overall the plants are easier to collect than the ones from Cao Bang ( the former grows on stone firmly anchored, delicatum grows on moss cushions) and they look nearly like seed-grown plants immediately after collection, so they were favored by a couple of Chinese traders for a couple of years. That type usually has stronger growth habit, with slightly larger leaves than Cao Bang type.
The province of Yen Bai has the giant type of helenae, like a normal helenae, but up to 8 cm flowers and the leaves can be up to 25 cm. The shape however is not as good as the Cao Bang type, and the flowers are of a muddy brown color mostly with "some" yellow...
Only some of the plants from Cao Bang can compete to be the smallest paph species. The smallest paph species I have ever seen for sure is a colony of Paph. coccineum from Moc Chau, the plants always are 4 cm leafspan, 5 maximum ( and 3-4 cm flowers !!!). That is the red type of coccineum as well, with the nearly red flowers. I think when more material will be available, coccineum will prove to have at least one forma. There are 2 types too of coccineum, one with plants that are about the size of henryanum, and brownish flowers, one with smaller plants and red flowers...
