Ariocarpus bravoanus var. hintonii
Flowers pink-purple with greenish-white margins, inner perianth
parts deep magenta.
|
|
This
specie starts blooming when still young. The first flower is larger
than the plant's body.
|
Habit: Solitary geophyte.cactus,
rosette-shaped with triangular, rough, dark green verrucese
tubercles..
Stem: Growing slowly to 6 cm in diameter 1.5 cm above ground
level in habitat.
Tubercles: Flat, triangular, up to 20mm dark olive green, with a
central woolly grove and two smaller glabrous, very distinct, perfectly
straight lateral groves 0.5-1.0mm wide,. The verrucose part of adaxial
tubercle surface is 8-11mm long and 11-15mm wide, the
remainder is densely and
finely verrucose, with a pale, almost crystalline appearance, edges
acute, not rounded apex acute and well-defined.
The central fissure
develops only with maturity.
Parastichy numbers: 5 and 8.
Spines: None.
Flowers: Pinkish-magenta flower, 4 cm in diameter.
Blooming season: August to October , it is frequently the
earliest species of the genus to bloom in cultivation.
Fruit: Pale red 2O x 5mm.
Seeds: 1.1-1.4(-1.5) x O.95 -1.2mm, testa black, tuberculate.
|
|
Cultivation: Grows in
alluvial plain that becomes muddy in
summer, so likes quite a lot of water then... but very
prone to rot other times of the year, Moderate water in
spring and
autumn, no water in
winter.
Full sun,
half shade. |

A young plant, the central fissure on the
tubercle develops only with maturity.
NOTE: Ariocarpus hintonii - discovered in 1981 - is a highland or southern
form of
A. fissuratus
from a geographically remote isolated line.
A. fissuratus var. hintonii, although
superficially resembling
A. fissuratus
of the Northern type, is closely related to
A. bravoanus, sharing many similar morphological characters,
tubercle structure, papillate epidermis, seed testa etc.
A.
fissuratus var. hintonii was therefore subsequently transferred to
subspecific status beneath A. bravoanus by Anderson & Fitz
Maurice. In fact some plants in the A. bravoanus habitat have a marked resemblance to A. hintonii, and these
taxon two may well represent extremes of the same species.
