No. 67 MAMMILLARIA TONALENSIS
Original reference: D.R. Hunt, The Cactus and Succulent Journal of Great Britain 41, 103 (1979)
Body: Freely clustering and offsetting from fibrous roots, the stems erect or decumbent, slender cylindrical, to 12cm, or more in length and 2-2.5cm. in diameter.
Tubercles: Short and obtusely terete-conic, about 5mm, long and 8mm broad at the base, light green, with watery sap, set in three and five spirals.
Axils: Naked or with slight wool.
Areoles: Sparsely woolly.
Spines: Radial spines, 9-12, up to 1cm long, acicular, straight, chalky white, the upper tipped chestnut brown. Central spines, 1, porrect, up to 18mm. long, acicular, hooked, smooth, chestnut brown at first but becoming almost black.
Flowers: Funnel-shaped, about 1.5cm, long and 10-12mm, wide when fully open.
Outer perianth segments brownish-pink; inner perianth segments narrowly oblong-linear, about 1.5mm. wide, carmine, with whitish
margins.
Fruit: Not known
Seed: Not known,
Type locality: Puente de Tonal a, Oaxaca, Mexico, on steep limestone rocks, lightly covered with bushes and with M.carnea and a plant allied to M.dixanthocentron.
Distribution: At present it is known only at the type locality,
Notes: This species was first collected by Herr Reppenhagen, on 17th October 1974 and, prior to its official description, bore his field
number 522, It was later collected by Dr, Lau at the same locality and given his number 1114. It is clearly allied to M.sphacelata and
David Hunt has included it in his Series Sphacelatae. As yet it is very uncommon in cultivation and seed has not been available. However, it should be easy to propagate vegetatively and as the species is clustering there is reasonable hope that reasonable numbers of plants will soon be forthcoming. Like M.sphacelata and M.kraehenbuehlii, another related species, it should not prove difficult to grow. On the debit side, it may also follow them in being rather reluctant to flower.
