forest, Moho River, 16 Oct. 1906, M. E. Peck 552 (rype in Gray 
Herb.). — Unique, apparently, in its 4-parted calyx, but in all 
other features in close agreement with other species of this genus. 
The generic name Gerardia L. (Sp. ii. 610 (1753); Gen. ed. 5, 266, 
no. 665 (1754)) has recently been referred by Dr. F. W. Pennell 
(Bull. Torr. Club xl. 119 (1913)) to the Acanthaceous genus Stenan- 
drium Nees (in Lindl. Introd. Nat. Sys. Bot. ed. 2, 444 (1836); in 
DC. Prod. xi. 281 (1847)). An independent investigation of the 
matter has convinced me of the justice of this treatment, which, 
in its bearing on the nomenclature of the North American forms 
that have been passing as Gerardia, will soon be discussed by the 
writer in Rhodora. The Mexican, Central American, and West 
Indian members of the genus Stenandrium to be transferred to 
Gerardia are as follows: 
GERARDIA acuminata (Urb.), comb. nov.— Stenandrium acumin- 
~atum Urb. Symb. Ant. vil. 382 (1912). 
v Gerarpia barbata (Torr. & Gray), comb. nov. — Stenandrium 
barbatum Torr. & Gray, Pacif. Rail. Rep. ii. 168, t. 4 (1855). 
GrrarpIA chamaeranthemoidea (Oerst.), comb. nov. — Sienan- 
drium chamaeranthemoideum Oecrst. Vidensk. Meddel. 1854. 139 
(1854). 
GERARDIA consobrina, nom. nov. — Stenandrium Wrightii Lin- 
dau in Urb. Symb. Ant. ii. 208 (1900). Not G. Wrightii Gray in 
Torr. Bot. Mex. Bound. 118 (1858).
