Fig. 200.—Malacocarpus grossei. Fig. 201.—M. napinus. Type locality: Paraguay. Distribution: Paraguay, between Carepegua and Acaay. The species is known to us only from illustrations and description; it and the pre- ceding one are much the largest of the genus, as known to us. The Bluhende Kakteen shows the spines as yellow, but they were originally described as white. Illustrations: Bluhende Kakteen 2: pi. 89; Mollers Deutsche Gart.
