Mammillaria thornberi is in the Center for Plant Conservation’s National Collection of Endangered Plants.
Cochemiea thornberi ist eine Pflanzenart aus der Gattung Cochemiea in der Familie der Kakteengewächse (Cactaceae). Das Artepitheton thornberi ehrt den US-amerikanischen Botaniker John James Thornber (1872–1962).[1] Englische Trivialnamen sind „Clustered Pincushion“ und „Slender Pincushion“.
Cochemiea thornberi wächst sprossend und bildet meist dichte Polster aus. Die trüb- oder purpurgrünen Triebe sind schlank zylindrisch geformt und oft an der Basis etwas verjüngt. Sie werden 5 bis 10 Zentimeter hoch und 1 bis 2,5 Zentimeter im Durchmesser groß. Die leicht schlaffen, konisch bis zylindrisch geformten Warzen führen keinen Milchsaft. Die Axillen sind nackt. Ein hellbrauner bis dunkel rötlich brauner Mitteldorn ist vorhanden. Er ist 0,9 bis 1,8 Zentimeter lang. Die 15 bis 20 Randdornen sind weiß oder auch gelblich mit dunkler Spitze und 5 bis 9 Millimeter lang.
Die breit trichterig auftretenden Blüten sind purpurn bis lavendelrosa und messen 1,5 bis 2 Zentimeter im Durchmesser. Die vorgestreckten, dicken Früchte sind rot. Sie enthalten schwarze Samen.
Cochemiea thornberi ist im US-Bundesstaat Arizona und im mexikanischen Bundesstaat Sonora verbreitet.
Die Erstbeschreibung als Mammillaria thornberi erfolgte 1902 durch Charles Russell Orcutt.[2] Peter B. Breslin und Lucas C. Majure stellten die Art 2021 in die Gattung Cochemiea.[3] Ein weiteres nomenklatorisches Synonym ist Chilita thornberi (Orcutt) Orcutt (1926).
Es werden folgende Unterarten unterschieden:
In der Roten Liste gefährdeter Arten der IUCN wird die Art als „Least Concern (LC)“, d. h. als nicht gefährdet geführt.[4]

Cochemiea thornberi is a species of cactus known by the common names Thornber's fishhook cactus and Thornber's nipple cactus. It is native to Arizona in the United States and Sonora in Mexico.[1][2]
This plant has numerous branches that all root in the ground, forming a clump of rooted stems all belonging to one plant. The stems are cylindrical and usually measure up to 10 centimeters tall, but known to reach 30. They are up to 3.5 centimeters wide. There are up to 21 bristle-like radial spines on each areole and one to three hooked central spines. The flower is up to 3 centimeters wide and has white or pink inner tepals with pink midstripes.[2] The flowers bloom most often after heavy rainfall.[3] The fruit is bright red and up to 1.5 centimeters long.[2] It is edible.[3] It contains black seeds.
This plant is associated with nurse plants. It often grows beneath the branches of Ambrosia dumosa.[3] The habitat is desert scrub. There are two main population areas in Arizona, one in the Avra Valley and Saguaro National Park and one on the Tohono O'odham Indian Reservation.[1] This species was abundant in the Avra Valley up until the 1930s until a freeze which decimated the population.[3] There are now a total of about 600 plants in all the populations together.[1]
