Some of the species of Castilleja are amongst the most 

 beautiful of North American plants ; we have seen fields of 

 tall grasses in Utah ornamented with the orange and scarlet 

 bracts of C. liniariafolia, and the bleak ridges of Sierra 

 Blanca in Colorado starred with the crimson bracts of C. 

 parviflora ? at an elevation of twelve thousand feet above the 

 sea. The distribution of the genus is singular; North 

 America is its head quarters, from the Arctic regions, exclu- 

 sive of Greenland, to Mexico, between which parallels 

 twenty -three species have been collected ; of which one is 

 widely distributed in northern Asia, and is the only repre- 

 sentative of the genus in the Old World; one other inhabits 

 the Andes of S. America, and one Brazil. None of the few 

 hitherto imported have continued long under cultivation, 

 possibly because, like their near allies Euphrasia and Barfmf, 

 they are root-parasites in a young state ; as with these latter, 

 the Castillejas all turn black in drying. 



Castilleja indivisa is one of the most brilliantly coloured 

 of the genus, its bracts, which arc orange-scarlet in a young 

 state, in age become of an intense carmine red and last a
