• Type: "Wingrah Pass, Napier Range (W.V.F.)."

• Text: "...clusters of flower-heads globose..."
• Comment: This is probably the validation of "Pterocaulon globuliflorus" published without a description by Fitzgerald, Western Mail 21(1068): 9, 25 (16 June 1906), as the localities given are the same. Fitzgerald (1918) gives the name as "globuliforus" but this is treated here as a correctable error for "globuliflorum".
