While there is notliing unusual m the erratic ciistriDuuoii 

 of some species or the occasional intrusion of species into 

 belts far removed from tlieir normal range, yet the presence 

 of the Arbutus here is rendered more than usually interesting 

 because of other northern and rare species that accompany 

 it, and that in this part of California seem to be limited to 

 this particular altitude and locality. 



PoLYGALA. CORNUTA, Kell., is the first of these. The speci- 

 mens here found are low shrubs with branches trailing to a 

 distance of four or five feet. The sepals are characterized 

 by the absence of the usual pubescence, but in all other 

 respects except size it appears to conform closely to the type. 

 The range of the species as recorded in the Flora Franch- 

 cana is " in the Sierra Nevada at middle altitudes from El 

 Dorado Co. northward." Though it is here far removed from 

 its accredited habitat, this may not be an isolated instance, 

 since the State Survey Botany informs us that Di". Torrey 

 ticketed specimens of his own as from Santa Barbara. While 

 the authors considered this probably a mistake, they may, in 

 view of the above discovery ultimately prove to have been 



correctly labelled. 



A short distance west of the Arbutus and at the same alti- 

 tude two other plants exist, in a few specimens, which are 

 worthy of note.

in the Cucamonga Mountains in 1881, it has since been re-

that it is not infrequent in the north: this is only its second 

 known station south of the Tehachapai Mountains. In the 

 same locality grows a Senecio, tall and stout, about three feet 

 high, and affecting the shade of the Quercus dumosa among 

 which it grows. It belongs to that series of which S. aroni- 

 Goides is the common type, and is closely related to S. asie- 

 phanii^, Greene; exactly resembling it in the form of the leaf, 

 but differing from it in the amount of the pubescence and in 

 the character of the inflorescence. It may seem to some impol-
