| description | Lexarzanthe is proposed as a new genus of the Cruciferae on the basis of Romanschulzia mexicana, a species originally described from fruiting material collected in the Mexican state of Guerrero. Recent collections of the same plant obtained in flowering condition reveal that this species differs from Romanschulzia in its ample corymbiform inflorescence with long and slender pedicels, in its much larger flowers with erect sepals and petals which persist during anthesis, as well as in its notably exserted stamens. In view of these differences the plant should be placed in a separate genus, which also belongs in the tribe Thelypodieae, but seems to be more closely related to Warea and Stanleya, genera considered as primitive in the family. |

Recent collections of the same plant obtained in flowering condition reveal that this species differs from Romanschulzia in its ample corymbiform inflorescence with long and slender pedicels, in its much larger flowers with erect sepals and petals which persist during anthesis, as well as in its notably exserted stamens.

Se propone a Lexarzanthe como género nuevo basado en Romanschulzia mexicana, taxon descrito originalmente de Guerrero con fundamento en ejemplares en fructificación. Las recientes colectas de la misma planta en flor, indican que la especie difiere de Romanschulzia en sus inflorescencias extendidas, corimbiformes, con pedicelos muy largos y delgados, sus flores de mucho mayor tamaño, con sépalos y pétalos erectos y persistentes en la antesis, así como sus estambres pronunciadamente exsertos. Dadas estas discrepancias, la planta debe ubicarse en un género distinto, también perteneciente a la tribu Thelypodieae, pero al parecer más cercanamente relacionado con Warea y con Stanleya, entidades consideradas como primitivas dentro de la familia Cruciferae.
