She was the first woman and the first botanist to ascend Mount Kinabalu in February 1910 while leading an expedition for three months that recorded 15 new plant species. One outcome of this expedition was to show the importance of New Guinea as a centre for subsequent radiation of plants to south and east. In 1912 she collected in Iceland. 1913 found her in the Arfak Mountains, Dutch New Guinea and she continued to the Bellenden-Ker Range in Queensland, Australia in 1914 and then returned to London from Tasmania in 1915. Her final visit was to South America. Her travels were limited after 1921 due to ill-health and she died in 1925 at Santa Cruz, on Tenerife in the Canary Islands.
