Alexander Clifford "Cliff" Beauglehole  (26 August 1920 – 19 January 2002) was an Australian farmer, botanist, plant collector and naturalist.

Life
Beauglehole was born in Gorae West, a locality near Portland in the Shire of Glenelg, of south-western Victoria, to the Beauglehole family, which were settlers from Cornwall, and arrived in the area in the nineteenth century. He attended Gorae state primary school but left after attaining his Qualifying Certificate to help his parents on the farm. He soon began making botanical surveys of the Portland area, as well as engaging in other natural history activities such as the study of Australian native bees, surveys of bone deposits in caves and the examination of beach-washed seabirds. By the 1940s, he had purchased the Gorae West farm from his parents and continued mixed farming there until 1968, when his family along with himself moved into Portland, in order to further his botanical career.

It is also during the 1940s that he discovered a new species of triggerplant, that is now commonly called Beauglehole's Trigger-plant; Stylidium beaugleholei. After 1968, Beauglehole was contracted to carry out botanical surveys in national parks and for the Victorian Land Conservation Council, which became his principal occupation. He published on a wide variety of natural history subjects, including the 13 volume The Distribution and Conservation of Vascular Plants in Victoria, written to cover the 73 study areas of the Victorian Conservation Council.

He died from complications after a stroke in 2002

Botanical Collections 
Beauglehole was reported to have had a private herbarium of over 23,000 specimens, and his numbering scheme indicates that over his lifetime he collected over 95,000 specimens. The bulk of his plant collections (approximately 69,500 specimens) are held at the National Herbarium of Victoria, Royal Botanic Gardens Victoria, with approximately 7,000 specimens held by the Western Australian Herbarium. Roughly another 150 specimens from the Ballarat region are held at the Federation University Herbarium.

Museums Victoria holds 583 of zoological specimens of vertebrates and invertebrates, including type specimens, that were collected by Beauglehole in Victoria, Western Australia, New South Wales, South Australia, Northern Territory, and Queensland.
