    Sorry, nope!

    Clue #1 - pot is 9cm diameter (from which you can work out, the leaves are 7-8mm long and a bit under 1mm broad; the two cotyledons are larger).

    Michael, reading the Coast Redwood Landscaping thread, I noticed your #1000 post. Congratulations and thanks for your participation on the UBCBG Forums! My guess is this that this is a photographs of an Abies, which is less than two years old. Since you were travelling in Turkey, A. bornmuelleriana appears to have needles less densely packed than A. cilicica, and is a medium green, rather than the darker green of the latter. Why do you use saucer under the pot?

    Sorry, no!

    Sorry, no!

    Still awaiting even the correct family . . .

    Clue #3 - the plant is only 4 months old

    So it doesn't dribble any run-off water onto my bedroom windowsill!

    Excellent!

    Yes! We've got the family now!

    Sorry, no.

    Clue #4 - it is grown from wild-collected seed, of a species officially listed as endangered

    Well then it looks like the Sequoia sempervirens burls I started growing last month.
    which, I guess, works with your Coast Redwood Landscaping thread mentioned earlier.

    Just a guess how about Cupressus Dupreziana, from the Tassile Mountains in the Sahara where it is alomost extinct ??

    Since it looks to be needle-leaved, though juvenile, it may belong to group Juniperus sect. Juniperus. Wikipedia. Since the provenance of the seedling is the Mediterranean, that excludes subsect. Juniperus. That leaves subsect. Oxycedrus and subsect. Caryocedrus, however the latter is excluded because the one species – J. drupacea - in this subsect. is not considered Endangered. Of the species in subsect. Oxycedrus native to the Mediterranean, the IUCN Red List of Threatened Species lists as Endangered: 1) J. brevifolia from the Azores; 2) J. cedrus from the Canary Islands. J. navicularis from Portugal is excluded as it is not listed as Endangered. Of note, the three other Juniperus species listed as Endangered are not in the needle-leaved subsections, but if some of the scale-leaved species of Juniperus have needle-leaved juvenile leaves, then these three species are excluded as native to regions outside of the Mediterranean: J. gracilior (Caribe); J. jaliscana (Mexico); J. standleyi (Mexico, C. America). The Arboretum de Villardebelle lists J. taxifolia as Endangered, however it is from China? There seems to be some controversy about whether J. brevifolia is a subspecies of J. oxycedrus. So between J. brevifolia and J. cedrus, the former likely has leaves similar to, but much smaller than, J. oxycedrus, which has green leaves up to 2 cm long; cross-section triangular; upper side two distinct stomatal lines on the upper side. The latter has green to glaucous-green leaves, 8-23 mm long and 1-2 mm broad. Thus J. cedrus most closely matches the seedling in question. Just a novice’s analytical guess; otherwise, I do not have a clue.

    There are two other similar varieties listed, Cupressus dupreziana var.dupreziana ,also Cupressus alantica(Moroccan Cypress) which is treated as a variety of the Saharan Cypress, all these trees are very rare and are on the Red list of threatened Species.

    There is one in the UK I know of at Hillier's Arboretum in Hampshire, must be 6 mtrs high.

    We have a winner! Congrats!

    Cupressus atlantica, grown from seed collected at 1930m altitude in the valley of the Oued-n-Fiis river, 30° 54' N 8° 21' W.

    Although sometimes treated as a variety of C. dupreziana, it differs from that in not exhibiting the unique male apomixis that C. dupreziana shows. Since that trait also prevents hybridisation and leaves them genetically isolated from each other, it is best to treat them as separate species.

    Photos of the wild trees the seed came from:

    Hadn't seen the #20 post when I guessed. What would the odds have been that we would have answered each others Stumper with the same tree...? It appears that I have a ways to go in this game.
