The lamps are to remind students that "As one lamp lights another nor grows less, so nobleness enkindles nobleness". The rose is a symbol of Mary, Mother of Jesus. The black and white section of the Crest is taken from the Dominican shield, for the Maryknoll Sisters are part of the Dominican order. The white symbolises purity and truth, and the black symbolises sacrifice. The other colours of the Crest are blue and red, which the former one stands for loyalty and the latter stands for charity. The Latin words "Sola Nobilitas Virtus", which mean "Virtue Alone Ennobles", at the bottom of the crest denote the school motto. The Ghost Pine Controversy A Norfolk Island Pine tree used to stand at a corner of the school lawn, facing the Waterloo Road Gate of the Primary Section. It was 71 years old and 23 metres tall. Known as the Ghost Pine among students, it has come to be seen as a symbol of the school. On 10 July 2009, the Former Students' Association issued a circular inviting former students to take photos with the ghost pine and bid farewell, citing the school management's decision to cut it down in two weeks. It was understood that the school management was worried about students' and public safety should the tree collapse, as explained in Sr Jeanne Houlihan's letter to former students. Several former students, some being specialists in landscaping and environmental science, proposed solutions to save the tree while making it safe for current students and the public. They were supported by over 2,000 students who signed a petition on Facebook to conserve the tree. The school's suggestion that the tree be chopped into smaller pieces to make souvenirs for students and former students was denounced by many former students as gruesome and analogous to ripping body parts from a corpse and sharing it among accomplices. Experts in the area, most notably Professor C.Y. Jim, Chair Professor of Geography at the University of Hong Kong, and Mr Ken So,
