In corn-fields in the north of England. 



A mile from Borough-bridge, in the road to Knaresborough, also 

 between Wetherby and Catall, Yorkshire ; and near West New- 

 ton, Northumberland ; always among corn. Dr. Richardson. 

 Plentifully on Stockton Common, and in many other parts of 

 the county of Durham, in corn-fields " approaching to peat j" 

 sometimes nearly obliterating crops of corn. Mr. James Back- 

 house. 



Annual. July, 2 or 3 weeks later than the former. 



Dr. Richardson distinguished this species, from our common R. 

 Crista galli, by its greater size, copious branches, narrower 

 leaves, and smaller^owers with a pui-ple (upper) lip. Ehrhart 

 has characterized it by the incurved tube of the corolla, which in 

 the former is straight. Mr. Backhouse, to whom I am obliged 

 for numerous wild specimens, says it may be known at first 

 sight by its greater size, being 2 feet high, much branched, and 

 bushy ; its much denser spikes ; and its yellowish bracteas, each 

 of which terminates in an elongated green point. The seg- 

 ments of the upper lip of the corolla are wedge-shaped, and 

 purple. Germen narrower, and more tumid, than in R. Crista 

 galli. Style prominent. Nectary heart-shaped, more spread- 

 ing, and greenish. The seeds are thick at the edge, and not 

 quite destitute of a membranous margin, but this is much nar- 

 rower than in the former. Prof. Afzelius long ago assured 

 me that R. major of Ehrhart differed in its seeds from our com- 

 mon Crista galli. The Alectorolophus n. 314, of Haller, which 

 is less branched, with broader leaves, and a hairy calyx, appears 

 very distinct from our R. major, and more allied to R. Crista 

 gain. I have R. major gathered by Mr. Davall, on some of the 

 loftiest of the mountains of Switzerland.
