Mabrya acerifolia, or brittlestem, is a mat-forming herbaceous perennial native to south-central Arizona. It has pale yellow tubular flowers. It was first described by Francis W. Pennell in 1924 in the genus Maurandya and transferred to Mabrya by Wayne J. Elisens in 1985. The epithet acerifolia refers to the somewhat maple-like shape of its leaves.

Holmgrenanthe petrophila (rocklady, formerly Maurandya petrophila) is a rare perennial desert plant in the plantain family (Plantaginaceae), and the sole species of the genus Holmgrenanthe. It forms low mats of branched stems growing from a woody base. The leaves have small spines along their edges. The solitary yellow flowers are tubular with five free lobes at the end, the upper two pointing backwards, the lower three projecting forwards. The species is known only from about ten locations, most in the Titus Canyon and the adjacent Fall Canyon, all within the Californian section of Death

Mabrya rosei is a mat-forming herbaceous perennial native to the Mexican states of Jalisco and Zacatecas. It has tubular flowers, whitish at the base and red to red-violet at the apex. It was first described by Philip A. Munz in 1926 in the genus Maurandya and transferred to Mabrya by Wayne J. Elisens in 1985. Munz did not explain the origin of the epithet rosei but listed the collector of the type specimen as Joseph Nelson Rose.

Mabrya geniculata is a mat-forming herbaceous perennial native to the Mexican states of Sonora and Chihuahua. It has pale yellow tubular flowers. It was first described in 1894 by Benjamin L. Robinson and Merritt L. Fernald in the genus Maurandya and transferred to Mabrya by Wayne J. Elisens in 1985. Elisens divided M. geniculata into three subspecies, M. g. geniculata, M. g. flaviflora and M. g. lanata. M. g. flaviflora was separated off as a full species, Mabrya flaviflora, by David A. Sutton in 1988. M. g. lanata differs from the nominate subspecies in having its stems and leaves densely

Mabrya coccinea is a mat-forming herbaceous perennial native to the Mexican state of Coahuila. It has red tubular flowers. It was first described by Ivan M. Johnston in 1950 in the genus Maurandya and transferred to Mabrya by Wayne J. Elisens in 1985. The epithet coccinea means red.

Lophospermum turneri is a climbing or scrambling herbaceous perennial native to Guatemala and the state of Chiapas in Mexico, where it was first collected. It has tubular flowers, lavender to violet in colour. It was first described by Wayne J. Elisens in 1985. The epithet turneri commemorates Billie L. Turner, described as "mentor of many students of the Latin American flora".

Lophospermum purpurascens is a climbing or scrambling herbaceous perennial native to Mexico, occurring in the states of Oaxaca, Veracruz and possibly Puebla. It has tubular flowers, white at the base and dark purple elsewhere. It was first described by Wayne J. Elisens in 1985. The epithet purpurascens means purplish or becoming purple.

Lophospermum chiapense is a climbing or scrambling herbaceous perennial known only from one location in the state of Chiapas in Mexico, where it was first collected. It has tubular flowers, white at the base and violet elsewhere. It was first described by Wayne J. Elisens in 1985. The epithet chiapense refers to its place of collection.

Lophospermum breedlovei is a climbing or scrambling herbaceous perennial native only to the state of Chiapas in Mexico. It has tubular flowers, white at the base and dark purple elsewhere. It was first described by Wayne J. Elisens in 1985. The epithet breedlovei commemorates Dennis E. Breedlove, described as a "prolific plant collector and authority on the flora of Chiapas".

Rhodochiton nubicola is a climbing or sprawling herbaceous perennial native to the state of Chiapas in Mexico and to Guatemala, where it grows in cloud forests at between 1,300 and 3,000 m (4,300 and 9,800 ft). It has dangling flowers, with a bell-shaped calyx and dark purple petals forming a tube. Unlike the better known Rhodochiton atrosanguineus, the petal tube is asymmetrical with two "lips". The species was first described by Wayne J. Elisens in 1985. The specific epithet nubicola is a noun derived from Latin nubes, cloud, and -cola, dweller, thus meaning "cloud dweller". It was

Rhodochiton hintonii is a climbing or sprawling herbaceous perennial native to the state of Guerrero in Mexico. It has dangling flowers, with a bell-shaped calyx and dark purple petals forming a tube. Unlike the better known Rhodochiton atrosanguineus, the petal tube is asymmetrical with two "lips". The species was first described by Wayne J. Elisens in 1985. The specific epithet hintonii commemorates G.B. Hinton, described as a "pioneer plant collector in Mexico". It was transferred from the genus Lophospermum to Rhodochiton by David A. Sutton in 1988.
