This work was first published (folio) in 1777. It represents specimens of the various genera established by Linnaeus in his Genera Plantarum. For the genus Amaryllis, Müller chose the Cape Belladonna. He wrote "The common name BELLADONNA — is a native of the Caribbee islands, Barbados and Surinam. Sp. Pl."

He did not identify this plant as Amaryllis Belladonna L. in this edition. It was identified as such in 1794, but Müller died about 1790.

Müller (John Miller) did some work for Philip Miller (no relation) at the Chelsea Physick garden, and contributed to Miller's Gardeners Dictionary of 1768. In that work, the common name "Belladonna lily" was assigned to Amaryllis reginae, in agreement with Linnaeus, Species Plantarum second edition, 1762.

The plate shown here is copied from Sealy (1939), and is not the plate found in the 1779 edition (left) which appears to be a simplified version. I have not yet seen the 1777 edition, and there was no 1771, though some of the plates were released before the "official" publication date. The plate clearly shows that the petals are not bent at the base ("nec ad ungues recurvatis") in agreement with Linnaeus's description of Amaryllis reginae.
