Question: Are both Lyonothamnus and Antirrhinum known as dragon flowers?
Context: Antirrhinum filipes (syn.  "Neogaerrhinum filipes") is an annual species of North American snapdragon, usually known by the common name yellow twining snapdragon.  This herbaceous plant is native to deserts of the southwestern United States and northern Mexico, where it is common. Antirrhinum cornutum (syn.  "Sairocarpus cornutus") is an uncommon species of New World snapdragon known by the common name spurred snapdragon. Dance in China is a highly varied art form, consisting of many modern and traditional dance genres.  The dances cover a wide range, from folk dances to performances in opera and ballet, and may be used in public celebrations, rituals and ceremonies.  There are also 56 officially recognized ethnic groups in China, and each ethnic minority group in China also has its own folk dances.  The best known Chinese dances today are the Dragon dance and the Lion Dance. Antirrhinum is a genus of plants commonly known as dragon flowers or snapdragons because of the flowers' fancied resemblance to the face of a dragon that opens and closes its mouth when laterally squeezed.  They are native to rocky areas of Europe, the United States, and North Antirrhinum vexillo-calyculatum (syn.  "Sairocarpus vexillocalyculatus" (Kellogg) D.A. Sutton) is a species of New World snapdragon found only in California and occasionally Oregon.  This wildflower is known by several common names, including wiry snapdragon, sailflower snapdragon, and Brewer's snapdragon. Antirrhinum nuttallianum (syn.  "Sairocarpus nuttallianus"), and known by the common names Nuttall's snapdragon and violet snapdragon, is a species of New World snapdragon. Antirrhinum majus (common snapdragon; often - especially in horticulture - simply "snapdragon") is a species of flowering plant belonging to the genus "Antirrhinum".  The plant was placed in the "Plantaginaceae" family following a revision its prior classical family, "Scrophulariaceae."  It is native to the Mediterranean region, from Morocco and Portugal north to southern France, and east to Turkey and Syria.  The common name "snapdragon", originates from the flowers' reaction to having their throats squeezed, which causes the "mouth" of the flower to snap open like a dragon's mouth. Antirrhinum virga (syn.  "Sairocarpus virga") is a species of New World snapdragon known by the common name tall snapdragon. Lyonothamnus is a monotypic genus of trees in the rose family containing the single living species Lyonothamnus floribundus, which is known by the common name Catalina ironwood, and the subspecies "L. f." ssp.  "aspleniifolius" and "L. f." ssp.  "floribundus". Pseudorontium is a genus of flowering plants with one species, Pseudorontium cyathiferum (syn.  "Antirrhinum cyathiferum"), a New World snapdragon known by the common names dog's-mouth and Deep Canyon snapdragon.  It is native to the deserts of northern Mexico and adjacent California and Arizona.  It is an annual herb producing a hairy, erect, non-climbing stem with many oval-shaped leaves.  The solitary flowers are dark-veined deep purple and white, often with some yellow in the throat, and are about a centimeter long.  Previously considered to belong among the New World "Antirrhinum" species, it is now considered the sole member of the related genus Pseudorontium.
