to the genus. 
Ventenat’s treatment of Caladium in Roemer 
Archiv fiir die Botanik follows the same course, discuss- 
ing C. bicolor and at the end mentioning ‘‘esculentum’’. 
Consequently, we feel that the standard species of 
Caladium is C. bicolor and not C. esculentum as advo- 
cated by Wight and accepted by certain recent authors. 
CATHARANTHUS G. Don, Gen. Syst. Gard. 
& Bot. 4 (1838) 95. 
Lochnera Reichenbach, Consp. Reg. Veg. (1828) 
134, non Lochneria Heist., non Lochneria Scop. 
On account of the earlier uses of the name Lochnera 
Reichb. must be replaced by Catharanthus G. Don. 
Dalla Torre and Harms (Gen. Siphon. fase. 6 (1904) 
406) are obviously in error when they refer Catharanthus 
G. Don to Vinca L. as Don treated but two species — 
C. pusillus and C. roseus — both of which are included 
in Lochnera by Engler and Prantl. 
The transfer of the plant known both as Vinca rosea 
L. and Lochnera rosea Reichb. was made by G. Don 
(Gen. Syst. Gard. & Bot. 4 (1888) 95). 
The synonymy of the two varieties of this species 
growing in the garden is: 
Catharanthus roseus (L.) G. Don var. albus 
(Sweet) G. Don, Gen. Syst. Gard. & Bot. 4 (18388) 95. 
Vinca rosea 1... var. alba Sweet, Hort. Brit. (1827) 
274. 
Catharanthus roseus (L.) G. Don var. ocel- 
latus (Sweet) G. Don, Gen. Syst. Gard. & Bot. 4 
(1838) 95 (sphalmate occellatus ).
