Q. Palmeri, Engelm, Bot. Cal. ii. 97. Advance sheets is- 

 sued Oct. 1st, 1879. The original description is as follows: 



A new oak is described by Dr. A. Kellogg, as follows: 



The Dunn oak (Quercus Dunnii). — From Lower California, presented by 

 Mr. G. W. Dunn. This is a small tree, or commonly a clustered shrub, rarely 

 exceeding 10 feet high, and three to four inches in diameter. The foliage 

 bears some resemblance to our evergreen field oak (Q. agrifolia), but the 

 male catkins are in long, dense-flowered tassels, similar to Q. densiflora, the 

 Chestnut or Tan-bark oak of the coast (mainly); cups like the Italian brig- 

 and hat and almost destitute of any distinct scales; color foxy-yellowish 

 More specimens are desirable for comparison; meanwhile it is thought best to 

 make it known under the provisional name above. Leaves, perennial, sub- 

 cordate-ovate, corneously spinous-dentate, teeth often rather remote and 

 somewhat repand, abruptly acute, rigidly re-curved, laminal wings more or 

 less elevated and waved — tomentum very close, dense, dull whitish, chiefly 

 beneath — one-half to one and one-half inches long, and about one-half as 

 broad, petioles short one-sixth to one-eighth the length; fruit solitary; ses- 

 sile or short peduncled, on wood of the previous year — male aments in long 

 fascicles, dense white or sub-creamy flowers— (like those of a castanea; want- 

 ing in the specimens); cup, obconically bell-shaped, the very obscure scales 

 broad and thin, continuously united (apparently) into a succession of rings, 

 one above the other, with lessening intervals to the sub-entire thin, involuted 

 margin; slightly fulvous externally, scar small, one-half to two and one-half 

 lines broad; gland oblong-ovate, acute. 



Juniperus Cerrosianus, Kellogg, 1. c. ii. 37; Hesperian, 

 March, 1860, with fig. — Dr. Engelmann states in Trans. St. 

 Louis Acad. vol. iii. 588, that a specimen of this in Herb. 

 Torrey belongs to J. Californicus. There are however 

 abundant specimens in the herbarium of Cal. Acad, in all of 

 which the berries are bluish-black, large and globular, 

 always having as many as three, and often four well devel- 

 oped seeds. The foliage certainly is very like that of J. Cal- 

 ifornicus, but the fruit is very different.
