Iphayini likhulu, liphuzi, noma njengoba libizwa nangokuthi i-Oregon pine - isihlahla amahlathi aso abhekwa njengendawo yokuzalwa yaseNyakatho Melika. Lesi sihlahla sikaphayini sibuye sibe uphawu lwesimo saseMontana. Ezindaweni zokuhlala zemvelo, ukukhula kwesihlahla kungafinyelela kumamitha angama-70, ezindlini zokufakelwa kungamamitha ayi-5. Ukwakheka komqhele kuyiphiramidi ngenkathi isihlahla sisemncane, eduze nokusondela ekubeni mdala. Awekho amagatsha amaningi esihlahleni, ayamithi futhi ayeluliwe, agobeke phezulu emaphethelweni.
Iphayin elisindayo linamagxolo aminyene (8-10 cm), ansundu obomvu, aqhekeke amapuleti amakhulu. Izigaxa zalesi sihlahla zingama-terminal futhi ziqoqwa ngama-whorls (izingcezu ezi-4-6 ngayinye), ubude bungafinyelela ku-15 cm ngobukhulu obufika ku-6 cm. Imbewu zikaphayini zinamaphiko. Lesi sihlahla sinezinaliti ezi-chic ezinde kakhulu (kufika ku-25 cm), zihlanganiswe ndawonye ndawonye (ezintathu zikaphayini we-coniferous) futhi sinombala oluhlaza okotshani. Ngenxa yezinaliti ezinde, umqhele wesihlahla ungabonakala ufiphele, ushibilika futhi uyimpandla.
Njengoba isencane, uphayini ungahambisa emazingeni okushisa aphansi. Ngasikhathi sinye, umuthi ubekezelela ngesizotha isomiso futhi uhlangana kahle ezindaweni ezinesihlabathi namatshe.
Iphayin esindayo inezinhlobonhlobo. Omunye wabo IWallich pine noma iHimalayan. Izici: Kukhula kufinyelela kumamitha angama-50, umqhele uphansi, kepha ububanzi, amagatsha wamathambo aphakanyisiwe. Amagxolo aqhekezwe amapuleti amakhulu kakhulu, izigaxa zinkulu, zibunjiwe ngesimo emilenzeni emide, kungathi kuphuma. Imbewu nayo inamaphiko, indawo yokuhlala yesihlahla seHimalaya. Njengephayin elisindayo, lingashona esemncane.
Okunye okuhlukile - uphayini ophuzi. Lesi sihlahla singobude obuphakathi, futhi umqhele waso uyinqaba. Ochwepheshe batusa ukuzalanisa izinhlobo eziphansi nje zikaphayini osindayo. Lesi sihlahla sizoba umhlobiso omuhle kakhulu wengadi.
