In a 1910 publication titled "Catalogue of the Flowering Plants and Ferns of Connecticut Growing Without Cultivation", author Charles B. Graves notes Guilford as a town known to support wild ''O. humifusa'' at that time.<ref name="catalogue-1910"></ref>  Graves also separately mentions North Guilford, however there is no such incorporated town in Connecticut and he was likely referring to the northern sections of Guilford.

The George Safford Torrey Herbarium at UConn contains a specimen of ''Opuntia humifusa'' collected in Guilford, Connecticut on August 27, 1950 by G. S. Torrey (CONN Accession #161634).  The collection location is described as "ledges in scrubby pasture" at Leetes Island.<ref name="gsth"></ref>  The record also notes that this collection was performed with the Connecticut Botanical Society, which may possibly still have field records pertinent to this ''O. humifusa'' colony.
