(holotype NY, isotype US) ; Laudat; calyx green, fleshy; 1903; Francis E. Lloyd

Excluded Species 



Schradera ligularis Rudge, PI. Guian. 1 : 29. t. 45. 1805. = Cephaelis (?) sp. 



The plate shows a head of terminal flowers on an elongated peduncle, but 

 surrounded by about eight distinctly free, elongate, narrowly lance-linear, long- 

 acuminate bracts. These are not united into a common involucre, a character of 

 the genus Schradera. It is probable, as Standley judged, that the species should 

 be relegated to the genus Cephaelis. 



Schradera longifolia Spruce ex Hook. f. in Hook. Ic. PL 1870. t. 1068. 1870. 

 = Stachyarrhena longifolia (Spruce) Hook. f. in Hook. Ic. PI. t. 1068. 

 1870. 



Schradera spicata Spruce ex Hook. f. in Hook. Ic. PI. 1870. t. 1068. 1870. 

 = Stachyarrhena spicata (Spruce) Hook. f. in .Hook. Ic. PI. t. 1068. 1870. 



Schradera umbellata Presl, Bot. Bemerk. p. 81. 1844. 



To be excluded because of the four-bracted involucre, four-rayed umbels, and 

 uni-ovulate cells of the ovary. Standley states (Field Mus. Nat. Hist. Bot. 13(6) : 

 75. 1936) that "the plant is referred with doubt to this genus by Presl. I suspect 

 that it may be a species of Cephaelis." Without an examination of the type, the 

 generic position of this plant is uncertain. Because of the characters indicated 

 above, it cannot be maintained in the genus Schradera, as that genus is presently 

 understood.
