Leucophyllum (barometer bush or barometerbush) [2] [3] is a genus of evergreen shrubs in the figwort family, Scrophulariaceae, native to the southwestern United States and Mexico. It is sometimes placed in the family Myoporaceae. [1] The dozen-odd species are often called "sages", although they have no relationship to the genus Salvia .
The solitary axillary flowers are bell- or funnel-shaped, with five lobes and two lips, and colors ranging from white to magenta to purple. The generic name is derived from the Greek words λευκός (leukos), meaning "white," and φυλλον (phyllos), meaning "leaf," referring to the trichome-covered foliage. [4]
These shrubs are found in sandy soils and have a high salt tolerance. They have become popular for edge and area plantings in warmer areas and in xeriscaping; they require minimal water, are easily shaped into hedges, and bloom over their entire surface. Cultivars of L. frutescens , L. candidum , L. laevigatum , L. langmaniae , L. pruinosum , L. revolutum , and L. zygophyllum have been developed. [5]
Leucophyllum shrubs are legendary for their ability to "forecast" rain, usually blooming several days prior to a rainstorm, apparently in response to humidity. They are sometimes called "barometer bush" for this reason. It is believed to be a survival trait in the plants' semi-desert habitats.
Prosopis is a genus of flowering plants in the family Fabaceae. It contains around 45 species of spiny trees and shrubs found in subtropical and tropical regions of the Americas, Africa, Western Asia, and South Asia. They often thrive in arid soil and are resistant to drought, on occasion developing extremely deep root systems. Their wood is usually hard, dense and durable. Their fruits are pods and may contain large amounts of sugar. The generic name means "burdock" in late Latin and originated in the Greek language.

Fagonia is a genus of wild, flowering plants in the caltrop family, Zygophyllaceae, having about 34 species. The latest reorganization of the genus took place in 2021 when systematists Christenhusz & Byng included Fagonia spp.. along with several other Zygophyllum genera, into a new genus named "Zygophyllum L." Species occurring in the US are commonly referred to as fagonbushes. The distribution of the genus includes parts of Africa, the Mediterranean Basin, the Mid-East, India, and parts of the Americas. Fagonia species have been used ethnobotanically by traditional practitioners under Ayurvedic and other TM healing regimes for many maladies. Species occur in deserts, dry washes, ditches and on rocky outcrops, including at altitude.
Dichondra is a small genus of flowering plants in the morning glory family, Convolvulaceae. They are prostrate, perennial, herbaceous plants, with creeping stems which take root readily at the leaf nodes. The flowers are white, greenish or yellowish, 2–3 mm diameter. Members of the genus are commonly known as ponysfoots and are native to tropical and cool temperate regions around the world.

Some species are additives to versions of the hallucinogenic drink ayahuasca.
