Now known as Pearcea hypocyrtiflora. Note that the flowers are shown with none of the lobes retracted — these open only under ideal conditions. The pouched form of the flower seemed to ally it in the minds of the botanists of the day with the “hypocyrta” species we now know as Nematanthus, hence the name applied to it in the 19th C.
Another (superior) print, from Curtis’s Botanical Magazine, was published a few years earlier. Both prints are of the plain green-leaved plant, as distinct from the darker more colorful foliage of the version in the photograph linked above.
