Geographical Distribution of Plants. 29 



it appears in. Lindley in his system (page 8) lias called it the 

 " Puccoon," which I suspect is a mistake, that name being given to 

 another plant, the Batschia canescens, the root of which is used to 

 dye a red by the native tribes. The root of the Sanguinaria hav- 

 ing a red juice may have led the compiler to consider it the 

 Puccoon. 



There are soil and situations suitable for the Sanguinaria below 

 Quebec, but I have not observed it so low down on the St. Law- 

 rence, and certainly it does not pass below the Saguenay. 



That beautiful genus, the Eschscholtzia of Chamisso, changed by 

 Torrey to the name of Chryseis, is not known native, east of the 

 Rocky Mountains, The five species now discovered all keep to 

 the belt of country bordering on the Pacific, south of the river 

 Columbia. In the valley of the Multnomah or Walhamet, on 

 which is built the city of Oregon, the rich colour and brilliant 

 Chryseis californica occurs, in latitude 43°, proceeding southward 

 into California. In that still warmer land the closely allied spe- 

 cies C. crocea, C. ccespitosa, C. tenuifolia, and C. hyperoides, 

 beautify the plains and meadows. The Chryseis Californica was 

 first discovered by Menzh-s, but afterwards described by the Rus- 

 sian naturalists accompanying Kotzbue. The other species were 

 made known by Douglas, who was for a short time engaged bo- 

 tanizing California. 



Although growing in a country where there is scarcely any winter 

 frost, and where the summer heat is intense, this genus nevertheless 

 appears to possess that hardiness that fits it to become an orna- 

 ment to gardens even in the coldest parts of our Province. In 

 latitude 54° north, it is cultivated as a hardy annual with the 

 greatest care, and if left to itself, it becomes a weed in the borders, 

 still retaining, however, undiminished beauty. The other genera 

 of this order, existing native of North America are found south, 

 and are never seen, unless in a cultivated state, within the British 

 territory. The Argemone Mexicana and Meconopsis diphylla are 

 both denizens of the Western States. The Meconopais heterophylla, 

 and M. crassifolia — with a single species each of the new genera, 

 Dendromecon, Meconella, Platystigma and Platysteman, — hold 

 ground still farther to the westward, in California and the Oregon. 

 With the exception of papaver nudicaule, all the plants of this 

 order, just passed under review, prefer a mild climate, and the 

 Sanguinaria, of which there is but one species, is the sole repre- 

 sentative of the order in Canada. The southern half of the tem- 

 perate zone holds the others.
