• ETYMOLOGY
Genus honouring Wilhem Weingart (1856-1936), German botanist and cactus specialist.
• DESCRIPTION
A genus of globose plants with the apex flattened, becoming sometimes elongated to shortly columnar (up to 30 cm high), usually solitary but also caespitose, with more or less napiform roots. Ribs strongly tuberculate, tubercles distinctly spiralled in Sulcorebutia; areoles close to the apex strongly woolly (linear in Sulcorebutia)-, radial spines spread out, stiff, subulate (pectinate, interlaced, appressed in Sulcorebutia, central spines sturdier.
Flowers diurnal remaining opened during night, usually self-sterile, with a very short tube (Weingartia s.s.) or elongated (Sulcorebutia), appearing near the apex, sometimes several in the same areole, sometimes fragrant, yellow, orange to red more or less purple, rarely white, also carmine red to scarlet, purple, violet, sometimes bi-coloured and even different colours within a population (Sulcorebutia), pollinated by bees. Fruits rather small, with naked scales,spherical to oboval, juicy at the beginning, then drying when ripe, basally dehiscent, floral remains persistent. Seeds variable, egg-shaped or helmet-shaped, black, usually dull or sometimes shiny, with a prominent hilum.
• HABITAT
The genus Weingartia (including Sulcorebutia) has a wide distribution range and grows in the high mountains of the Andes, on high-plateaus, often mimetically, almost completely buried, among grasses, on rocky soils, on rocks or in crevices, from 1600 m up to 3600 m in altitude. We often find the species associated with mosses and lichens.
