Garden, Mexico, sent to him by W. HIGSON, Esq. of Manchester, has raised several plants that are not

annotated the sheet in K used for t. 3295 (ex Herb. Hookerianum) as the ‗Holotype‘. Interestingly there is
one sheet in the ‗Cultivated‘ material covers that is of one capitulum on part of a pedicel with a printed
label. This label notes that the specimen is from the original plant grown by Mr Edward Leeds and could
therefore be counted as an isotype.
