未圓湖邊一行高大的喬木，有水松，落羽松，和池杉，三種同屬於杉科，樹幹基部都具膝狀呼吸根，以適應水生環境。落羽松雖名為松，與松無關。落羽松葉片表面看似複葉，如一片羽毛，細看是長條形的小葉，在小枝兩邊排成兩行，而學名中的 distichum，即是兩列的意思。北美引種的大樹, 秋天可賞黃褐色落葉。

Alongside Lake Ad Excellentiam grow a line of tall trees, including the Water Pine, Bald Cypress and the Pond Cypress.  All belonging to the Taxodiaceae family, they have in common woody 'knee' roots that project from the ground or water, allowing them to live in aquatic habitats.  The Bald Cypress seems to have feather-like compound leaves, but when examining in detail, they are in fact elongated small leaves arranged in two ranks along a branchlet.  In its scientific name, 'Distichum' exactly means two rows.  The Bald Cypress is an imported species from North America.  It gives a fantastic view of yellow fall leaves.
