Summary
[edit]DescriptionДъб (дърво 9) – жълъди.jpg |
Български: Дръжкоцветен дъб с характеристики, излизащи извън рамките на типичната видова принадлежност. Не е изключено да става въпрос за някоя от разновидностите (подвидове?) на Quercus robur L., описани в научната литература – Q. haas Kotschy например, или за интересна местна форма. Вероятността за хибрид първо поколение между дръжкоцветен и космат дъб ми се струва по-далечна – единственият външен белег, който не се вмества в обичайната за Q. pedunculiflora K.Koch морфологична картина, е гъстото овласяване на клонките (перманентно) и плодните дръжки (!). Последните имат значителна дължина. Други белези: едро дърво, листата - дълбоко нарязани, също с обособени дръжки, жълъдите са силно удължени, с плитки купули, покрити от плоски люспи със свободни връхчета, кората е неотличима от тази на дръжкоцветен/обикновен дъб. |
