Hugo Flecker (7 December 1884 – 25 June 1957) was an Australian medical practitioner, radiotherapist, toxicologist and natural historian.
He undertook valuable work on the Queensland Finger Cherry and the Tar Tree and identified the deadly box jelly, Chironex fleckeri.
From 1935 he contributed a weekly column to the Cairns Post on behalf of the Naturalist Club, in which he publicly advocated the establishment of a botanic garden at the recreation reserve.
It returned briefly to the Cairns Botanic Gardens from 1967 to 1971, but is now fully incorporated in the general collection at the CSIRO Division of Forest Research at Atherton.
[2] In 1934–35 a significant advance was made with around 25 acres (10 hectares) of the reserve on the lower slopes of Mt Islay cleared of heavy undergrowth and planted with young trees.
Trees and shrubs of a less "permanent" nature were to be removed and relocated to other parts of the reserve allowing for the development of avenues lined with pine, acacia, palms, Poinciana and others.
It appears that oil palms, poincianas, hoop pines, two rubber trees, a Dillenia, a Schizolobium, an Indian mango, a Wongi plum, a Terminalia and a Malay Apple were planted during this period by Les Wright.
[2] In 1982 new entrance gates were erected at the 1971 Flecker Botanic Gardens to commemorate the 50th anniversary of the founding of the North Queensland Naturalists' Club.
