On the sign:
טוקסדיון דו-טורי
Taxodium distichum

תפוצה טבעית: דרום-מזרח ארה"ב.

העץ הוא קרוב משפחה של עצי הסקוויה (עצים מס.30 Click for sign's details ו-31 Click for sign's details). גם עליו צומחים בשתי שורות מקבילות,לאורכם של ענפים דקיקים. בחורף עליו הירוקים בהירים הופכים חומים ובדרך כלל נושרים, בשונה ממחטניים אחרים.

Swamp Cypress (Bald Cypress)
Taxodium distichum

Natural range: S.E. USA

In spite of its name, this is not a cypress, but a relative of the Sequoias (trees 30 Click for sign's details and 31 Click for sign's details). Like them, its leaves form two parallel rows along thin twigs. Atypically for a conifer, in winter its leaves turn brown and often drop.

בטבע העץ גדל בביצות, מה מאפשר לעץ לחיות במים? ואיך אותו העץ יכול לגדול כאן בישראל הצחיחה?

[a question]
As the name suggests, this tree lives in swamps. What enables a tree to live in water? And how can the same tree grow here in arid Israel?

[הפאה הרביעית של הקוביה]
[The fourth face of the cube]
[התשובה לשאלה]
בביצות, שורשיו של העץ מפתחים "ברכיים" חלולות מעל המים, המספקות לו את האויר הדרוש; כאן בקמפוס אין, כידוע, ביצות, ולכן גם אין "ברכיים". הממטרות מספקות את הלחות הדרושה.

[The Answer to the question]
In swamps, special hollow projections of this tree’s roots, called "knees," grow upward above the water level and take in air. Here, no swamp, no knees; but the campus sprinklers provide enough moisture for survival.
