  • Discussion

    The northern form of the mayu was collected so frequently by the earlier botanists in Chile, by Gay, Poppig, Bertero, Cuming, Macrae, Bridges and Mathews, that it tended to eclipse the original C. stipulacea of Pavon both in herbaria and in the literature. While variable in pubescence, the foliage tends to be of a darker green than that of var. stipulacea; it is perhaps of thinner texture when fresh. The portrait in Curtis’s Botanical Magazine cited above is an excellent likeness. At the time this was written up by Turrill the source of the model was unknown, but according to a letter filed with a cultivated specimen at Kew it was grown from seed collected by G. W. Robinson in Renaca valley 10-12 miles north of Valparaiso.
