Where was David Livingstone heart buried?

Dr. David Livingstone was born on March 19, 1813, in Blantyre, Lanarkshire, Scotland. He died from malaria, and internal bleeding caused by dysentery, in Zambia, to the southeast of Lake Bangweulu. According to his journal, the date was May 1, 1873. But his faithful attendants, Chuma and Susi, reported the date as May 4. They arranged for his body to be taken back to Great Britain, for burial in Westminster Abbey. But they buried his heart, and internal organs, under a mvula tree near where he died. The site's now the location of the Livingstone Memorial. The slow-growing tree's decay-resistant wood often is substituted for teak. For this reason, it's aka African or Nigerian teak.
