The heads of this plant are much like those of H. Lastii Engl., 

 but the foliage is quite different. Judging from the description, 

 its probable affinity is with the recently published H. leptothamnus 

 Moeser ; but this, inter alia, has heterogamous heads with only 

 fifteen florets.

 alt. Folia usque ad 2 cm. long, et 7 mm. lat., pleraque vero 

 minora. Pedunculi nudi, summum circa 8 cm. alt. Capitula

 2-5) mm. lat., in sicco grisea. Corollae 8 mm., styli rami 1*5 mm., 

 achaenia 5 mm., pappus 8 mm. long. 



This belongs to Muschler's § Emilioidei, and is nearest S. 

 Marlothianus O. Hoffm., and especially the var. minor of that 

 species ; from this it can easily be distinguished by the more 

 congested differently shaped leaves, the shorter peduncles, and 

 the more numerous hair-tipped involucral leaves.
