Chimaphila umbellata Nutt. Gen. 1: 274. 1818. 
Chimaphila occidentalis Rydb. No. Am. Flora 29: 30. 1914. 
This species can now be reported from Southern California, 
having been collected in the Dollar Lake region of the San 
Bernardino Mountains at 8750 feet altitude, F. W. Peirson 820. 
This discovery and that of Pyrola picta Smith, Johnston 2860, 
add two species of Pyrolaceae to the list prepared by Parish 
(Pl. World 20: 247. 1917) for the San Bernardino mountains.

This variety is the form of the species frequent through the 
pine belt of the San Bernardino Mountains and differs from the 
typical form, which is not uncommon on the plains at the foot 
of the mountains, in its much smaller follicles. Many plants 
of the valley-inhabiting A. eriocarpa Benth. have been seen by 
the authors, but none have been noted which failed to have 
fruit much larger than in the variety here described. A. erto- 
carpa has follicles 8-10 cm. long on pedicels 4—6 cm. long, while 
the seeds measure about 8 mm. in length and have a coma 24 
mm. long. 
The small follicles can not be attributed to the blighting 
action of frost, for all produce perfect seeds and in all colonies seen 
the fruit was uniform in size and as here described. Further 
exploration may reveal the fact that the pine-belt form of A. 
eriocarpa found in the San Jacinto and San Gabriel Mountains 
is also referable to this variety; fruiting material from these 
ranges is lacking.
