| Pinus syluestriformis is endemic to the northern slope of Changbai Mountain (Vostochno-Manchzhurskie gory in Russian). It is a protected species. It prefers the volcanic soil and the cold climate. Growing location has annual average temperature 4.4 Celsius or 39 Fahrenheit. January temperature -18--15 Celsius or 0-5 Fahrenheit. Some believe it is a variation of the Scots Pine. Pinus syluestriformis grows to 32 meters or 105 feet high. In places of strong wind, other trees grow horizontally; but this pine stands upright. It also sheds all skins off every now and then revealing a whitish trunk. Perhaps for this reason and the cold winter, there is no known pest for this pine. Locals call it "beauty pine".

| Marvelous pines. They're not just some rather impressive Scot's pines then? +oM |

| snasxs, FWIW I for one appreciate you bringing these rare and usually endangered species to the forum. Most of which I would not have never known of their existence otherwise. In this case, a VERY impressive pine. To your knowledge, has anyone tried to grow it elsewhere? Also being that cold, I'm sure their growth rate is VERY slow. Makes me wonder how old those large trees are. Arktrees |

| +oM, I see a Scot's pine daily. The bark of my Scot's pine is light orange. My Scot's pine is not this tall and it is not straight up. The pine needles of my Scot's pine are sparce. Do you know if P. syluestriformis is considered an independent species? Has there been any genetic studies? |

| Arktree, you are not to blame. This pine was first identified late in 1976. Ernest Henry Wilson did not find them for a reason. P. syluestriformis has tiny natural presence. They are restricted to two locations of a total of 113 hectares (279 acres) on the north slope of the Changbai mountain. It is claimed that personnel record has been established for each older specimen, now. P. syluestriformis has been artificially cultivated and used in cities. The pine appears to do very well. It is observed that P. syluestriformis is a relatively fast-growing tree. Two year old seedlings are about 15 meters or 50 feet. The seedlings need well drained soil. The official name is "Changbai Scotch Pine" ("Changbai" means "long-white" in English). |

| Pinus sylvestriformis (-v-, not -u-!) is usually treated as a synonym of Pinus densiflora (e.g. Farjon, Pines, ed. 2, 2005) or variety of it (P. densiflora var. sylvestriformis (Takenouchi) Q. L. Wang). The Flora of China differs in treating it as a variety of P. sylvestris but without explanation why; the needle morphology distinctions it cites from P. sylvestris (longer, slender) are the same as P. densiflora. If you put a specimen through the Flora's Pinus key, it keys out under P. densiflora, not under P. sylvestris. Couple of other corrections; it was first discovered in 1942 (J. Jap. Forest. Soc. 24: 120); and the correct spelling is "Scots" (not "-tch", and no apostrophe). Oh, and I guess you mean 15 centimetres (not metres!) for 2-year old seedlings ;-) Resin |

| Resin, what is the name: Pinus syluestriformis (Takenouchi)T.Wang ex Cheng ? |
|
| Resin, I see, it should be Pinus sylvestris L. var. sylvestriformis (Taken.) W. C. Cheng & C. D. Chu. I was just confused with certain websites written by unprofessional. |
|
| Resin, the "Scot's" error was introduced by +oM. I was confused by his post. Thank you for your clarification. |
