Givat Ram, Jerusalem, Israel
Click here for a map that contains other items in the area

On the sign:
קליטריס מיובל
Callitris verrucosa

תפוצה טבעית: אוסטרליה

הקליטריס שייך למשפחת הברושיים, למרות שהוא עצמו אינו ברוש. מתפתח יפה באזורים צחיחים ונפוץ מאד בישראל.

[הפאה השנייה של הקוביה]
[The second face of the cube]
Rough Pine (Scrub Pine, Cypress Pine)
Callitris verrucosa

Natural range: Australia

In spite of its common name, this is not a pine (no long pine-like needles), nor a cypress, though a member of the cypress family. Growing well in arid regions, it is widely planted in Israel. It often invades wild habitats.

[הפאה השלישית של הקוביה]
[The third face of the cube]
השם המדעי Callitris "שלושה קשקשים"; verrucosa פירושו "מיובל", מלשון "יבלות". מדוע הוא "זכה" בשני שמות אלה? רמז: הבט באיצטרובלים.

[a question]
The scientific name Callitris means "three scales," and verrucosa (as in varicose veins) means "warty." Why these two names? (Hint: Look at the tree’s cones).

[הפאה הרביעית של הקוביה]
[The fourth face of the cube]
[התשובה לשאלה]
לאיצטרובליו של עץ זה שני מאפיינים מיוחדים:
1) הבט באיצטרובל מכיוון הקצה שאינו מחובר לענף ושים לב לסידור של קשקשיו: שלושה גדולים ושלושה קטנים, לסירוגין.
2) שים לב גם לבליטות (דמויות יבלות) על פני האצטרובל.

[The Answer to the question]
This tree’s cones have two unusual features:
1) Look at a cone end-on (that is, with the stem furthest away from you) and see its pattern of three large and three small scales in alternation.
2) See also its characteristic bumpy ("warty") surface.
