and Q. agrifolia, however, in that it develops the fruit the sec- 

 ond year while they mature theirs the first. Some do not seem 

 able to detect this fact unless they find the fruit and undevel- 

 oped ovules on the same twig, a circumstance seldom met with, 

 for only the most vigorous twigs develop fruit two years in suc- 

 cession, but when it is known that the flowers appear on the 

 young shoots in the spring, it goes without saying that, when 

 the fruit develops the first year, it will be found on the twigs of 

 the same season's growth, while those that develop the second 

 year will be found on last year's twigs. Knowing this, it can, 

 in nearly every case, be easily learned which year the fruit de- 

 velops. 



Upon the re-examination of my material I became con- 

 vinced that my determinations alluded to above were correct 

 and that these plants agree well with those from the more 

 northern part of the state, and in addition to my former ma- 

 terial, I have had the advantage of another season's collecting 

 and am enabled to extend the range still further. Besides this 

 material I have had the privilege of examining that in the fol- 

 lowing herbaria : Brandegee, Parish, California Academy of 

 Sciences and Stanford University, in all of which I found more 

 or less from our range. I give below a list of the specimens I 

 examined, which were collected below the Tehachapi, including 

 the collector and the herbarium in which the specimens are to 

 be found :
