As noted above, "Lophospermum" species have in the past been placed in "Maurandya" and the two genera have regularly been confused, particularly in cultivation. For example, the cultivar "Lophospermum" 'Magic Dragon' (a cross between "Lophospermum" 'Red Dragon' and "L. erubescens") was patented under the genus name "Maurandya". Cultivated species of "Lophospermum" have longer flowers than those of "Maurandya" and leaves with toothed rather than entire margins. The Suntory cultivars were patented under the generic name "Asarina", now treated as an entirely European genus.
