Thelocactus rinconensis subs. phymatothelos (10 seeds)

Thelocactus rinconensis subs. phymatothelos, better known as Thelocactus phymatothelos, can be distinguished from other forms of the Thelocactus rinconensis complex because the stem is always strongly depressed and glaucous, the spines are few, shorter and slightly curved, and the flowers are more or less clear pink.
Habit: Usually solitary or very slow to offset, develops a squat and highly ribbed stem with a flattened top.

All seeds are fresh of this season and obtained from my personal collection.
NOTE: cactus seeds could be sown in any season under control environment, however if you wanna go with nature then best time to sow the seeds is early spring/summer )
