46 Contributions from the Gray Herbarium 
ment. The name to be adopted for the very common species there 
called Simsia foetida, which has generally passed as Simsia auricu- 
lata or Encelia mexicana, is SIMSIA AMPLEXICAULIS (Cav.) Pers. 
Syn. ii. 478 (1807), based on Coreopsis amplexicaulis Cav. De- 
script. 226 (1802). To its synonymy should be added Helianthus 
trilobatus Link | Enum. ii. 352 (1822), the types of which I have 
examined at Berlin. The typical form, with pubescent 2-awned 
achene, may be called 8. AMPLEXICAULIS (Cav.) Pers. var. genuina: 
achenio appresso-pubescente, pappo biaristato. The form with 
glabrous epappose achene becomes S. AMPLEXICAULIs var. decipiens 
(S. foetida var. decipiens Blake, Proc. Am. Acad. xlix. 387 (1918)). 
The specimen of Palmer 440 (anno 1885), the type collection, in 
the Kew Herbarium, belongs to this form.
