This species is nearly allied to S. sogdiana Bunge, which is a 

 very strict plant, while S. aperta is less ose more diffuse. The 

 latter has shorter leaves but longer spines upon the leaves (by 

 S. sogdiana „breviter cuspidata sed vix pungentia"), and the sepals 

 form no cover over the fruit, which lies as in the bottom of a bowl 

 (aperta). By S. sogdiana the superior parts of the sepals form 

 „discum convexum iuduratum". This is te be seen upon the 

 foregoing species, but not at all upon this. — To this species be-

 by him by Eepetek 24. V. 1898 (with the Name S. sogdiana Bge.).
