16-18 mm. in diameter and the acorn ellipsoid, over 2 cm. 

 long and about 16 mm. broad. Sargent's PL 385, Fig. 13, 

 represents this species. It may be remarked here that J^. 

 undulata of DeCandolle's Prodromus is not J£. undulata 

 Torr., but J^. Fendleri Lieb. This explains why Alphonse 

 DeCandolle associated obtusifolia with J^. undulata. 



Jt>iiercus undulata y pedunculate/, A. DC* See J^. Fendleri 

 above. 



£>iiercus Emory i Porter & Coulter j (not Torr.), was based 

 on specimens collected by Brandegee at Canon City. The 

 original I have not seen, but others collected by him at the 

 same place later and named J^_. Emoryi belong to J^_. fun- 

 gens Liebm. 



£>uerctis undulata y Jamesii Engelm.J is the typical J^. 

 undulata and based on the type. 



jgiiercus tmdulata o Wrightii Engelm. 1. c. and 



£>iiercus undulata var. pungens Engelm. § are both J^. 

 pungens Liebm. 



£>uercus undulata var. grisea Engelm. || is J^tiercus grisea 

 Liebm. 



Quercus undulata var. oblongata Engelm., IF is J£. oblongi- 

 folia Torr. 



^jiercus turbinella Greene.** Sargent refers this species 

 partly to J^. undulata and partly to 4L- dumosa. As far as I 

 can judge, Professor Greene had only one species in his de- 

 scription, and this is well drawn, as is also his plate 28. Pro- 

 fessor Wooton, of the Agricultural College, New Mexico, 

 has penciled his views on the sheets in the Columbia herb- 

 arium ; these are of great value as Professor Wooton has 

 spent many years in the field in New Mexico and Ari- 

 zona. He thinks that it is a good species and identical
