 211 (type coll.: Brit. Mus., Kew). Vernacular name "Acaguale." 

 — Distributed as a Scleropus (i. e. Sclerocarpus) under an unpub- 

 lished name attributed to Schultz Bipontinus, which as originally used 

 by Schultz can have had no application to the specimens. The species 

 comes near G. longifolia and G. annua Rob. & Greenm., but is distinct 

 in its short involucre.
