Hassler 5178 (G [G 306915, upper portion of sheet!]; isolectotypes: BM [BM504271!], G [G306915, lower portion of sheet!, G306937!], GH [GH47341!], K [K574196!], MO [MO260054!], MPU [MPU14845!], NY [NY262918!], P [P623190!, P623191!], S-R [S-R10542!], UC [UC935372!]).

Notes:— The type collection of C. maracayuensis is found in G, where most of Emile Hassler’s collections are deposited, especially the ones from Paraguay ( Stafleu & Cowan 1979). Five sheets of Hassler 5178 were found in G, requiring lectotypification. The specimen G306915 (upper portion of sheet) is here selected as lectotype, because of its open pistillate and staminate flowers and well-conserved state.
