Mammillaria barbata
M . barbata. Engelm. in Wislizenus., Mem. Tour Northern Mexico 105, 1848: Trans. Acad. Sci. St, Louis 2: 201, 1862.
Simple (or caespitose), depressed-globose; sap watery; axils naked.
Central spines (several), robust, 1 (-2) hooked, erect, dark; radial spines numerous (20 or more) in several series, the outermost up to 40, hair-like, the inner stronger, tawny, 10-15, 6-8 mm. long. Flowers (15-) 17-20 mm. long and broad; outer perianth-segments somewhat ciliate, green, inner rose-red (light straw-coloured or greenish); stigmas 5-6 (-7), greenish yellow.
Fruit oblong, 10-12 mm. long,-green, dried perianth persisting; seeds dark brown (black).
Described from a single dead fruiting specimen collected by Wislizenus in Mexico, in the State of Chihuahua, near Cosihuir(i)achi. Engelmann propagated this from the seeds and added to the floral description in 1862. The species was recollected at the type locality by Hose in 1908. Engelmann's description was amended, as noted in brackets above, by Britton and Hose, The Cactaceae 4:144, 1925.
Engelmann's nomenclatural type may be preserved at the Missouri Botanical Garden (MO).
