An extract of a letter written by Bartlett to Galloway in January 1982 illustrates his indefategible approach ... I have returned from the incredible wilds of the West Coast of the S.I. after (1) spending a night in the bush on the coast near Bruce Bay cut off from the beach by rising tide! (2) falling into a tarn (deep!) near the Percy Pass (Manapouri) (3) nearly stranded on a limestone bluff at Castle Hill, Cave Stream 50' below! (4) Forgetting my boots and having to climb up through the bush above Wilmot Pass in my socks!... Bartlett's lichen and bryophyte collections are represented in New Zealand and international museum collections. Auckland Museum holds the holotype of Bartlettiella fragilis, a lichen genus he first collected in the north west Ruahine Range, and there are Bartlett specimens in the Natural History Museum, London. Bartlett added some fifty species of mosses to the New Zealand flora. In 1985,a new family of mosses, the Hypnobartlettiaceae, was named in his honour (based on specimens he collected in North West Nelson). In addition to collecting specimens, Bartlett published around 24 scientific publications.
