Cedronella PALLIDA, Liudl. Bot. Reg. 32, t. 29, is known only 

 from the figure and description. It was raised from seeds, probably 

 from Chihuahua; and if the species varies as widely as does C cana, 

 Hook., it may include the plants above characterized. But Liiidley's 

 figure makes the stem and calyxes hirsutely pubescent, the inflores- 

 cence open, the flowers nearly an inch long, and the lower lip of the 

 corolla 3 or 4 lines long. 



Cedroxella cana, Hook., as to the originally published form, we 

 cannot well distinguish from G. Mexicana. But in New Mexico it 

 runs into a form, var. lanceolata (collected by Dr. Rushy and by 

 G. R. Vasey), with small, narrowly-lanceolate, and entire leaves, 

 which difEer most widely from C. Mexicana.
