The female cones are always solitary, but of the male cones three or even four may 
arise from the same rootstock. Weddell found this plant in the neighbourhood of 
Villa Maria and on the journey from that town to Matto Grosso (Villa Bella). Santa 
Cruz is the most easterly point at which it has been seen, and also, so far as known, 
marks the limit of eastward extension of Cycads in South America. [Bolivia Or.]
