Simsia frutescens Gray in Torr. Bot. Mex. Bound. 89 (1859) =

 mcnesia hispida HBK. Nov. Gen. iv. 227 (1820). Encelia hispida 

 Hemsl. Biol. Centr.-Am. Bot. ii. 184 (1881). This species, with 

 "foliis alternis, sessilibus, ovato-oblongis, obsolete serratis, supra 

 piloso-, subtus sericeo-hispidis," and hispidulous stem three-flowered 

 at apex, has not since been recognized. The description points to a 

 poorly developed S. foetida. 



Simsia pastoensis Triana, Ann. Sci. Nat. ser. 4. ix. 40 (1858), from 

 Columbia, has not since been identified. It seems to be related to 

 S. puhescens Triana and S. Sodiroi (Hieron.) Blake. The original 

 description reads thus: "Suftrutex, ramis teretibus sparse molliter 

 pilosis et inter pilos puberulo-glandulosis asperulis; foliis summis 

 alternis et subbracteiformibus, inferioribus oppositis breviter petio- 

 latis ovatis acutis serratis, supra sparse decumbenti-pilosis et glandu-
