More information on Arunachal Discoveries as several people have asked for more details.

The following species are completely new to Science and therefore are unnamed.

1. an evergreen azalea. None are reported from this area. This was a great surprise.
2. A species in subsection Falconera looks like R. protisum and sino falconeri with good indumentum
3. A species related to R. aperantum. This was another really curious plant. Nothing quite like it.
4. A new species related to R. sanguineum or R. parmulatum.
5. A Maddenia or Tephropepla species. No idea what this could be.

2 species introduced for the very first time
Plus R. kasoense this is Autumn flowering with 4-5 yellow flowers. I can send scans if the one attatched to the e mail was not let through your system.

R. boothii both introduced for probably the first time. This is a bright yellow species suitable for west coast and mild gardens. It was in cultivation but seems to have been lost: we have not seen any correctly named plants for 30 years at least.

Other interesting discoveries
R. exasperatum only found once or twice before. Red flowers and wonderful purple new growth.

R. ludlowii introduced by Ludlow & Sherriff in the 1930’s and not seen since. A tiny, tricky alpine with yellow flowers, used very successfully as a parent at Glendoick by Peter Cox to raise the very well known bird hybrids: ‘Chikor’, Curlew’, Wren’ etc.

R. tsariense found at last, We failed to locate it in Tsari, Tibet and I doubt it occurs there at all.

R. sherriffii and R. thomsonii ssp. lopsangianum

Primulas
P. vaginata ssp. normaniana
P. elizabethae

Neither are in cultivation.

4 species of Sorbus, probably 2 are new.
