NEW CBANOTHUS. 65 



the veins beneath, these prominent, of elongated obovate out- 

 line cuneately tapering at the base, at apex very obtuse, even 

 often almost truncate, minutely serrulate : umbels nearly sessile, 

 ,each maturing a single dark-purple fruit large for foliage, 3 - 

 seeded. 



The type of this new species, allied to JR. rubra, is by Cope- 

 land, from Sisson, Calif., 15 Aug.1903, distributed by Mr. C. P. 

 Baker under n. 3833. There are traces of the same from Butte 

 Co., by Mrs. Austin. 



New Species of Ceanothus. 



The study of a new Ceanothus from New Mexico allied to 

 what is commonly known in California as C. integerrimus has 

 recalled to my mind what I learned at Kew ten years ago, but 

 have never yet published, as to the real identity of the common 

 shrub of California. 



In the summer of 1888 Dr. C. Parry brought to me for 

 inspection a Ceanothus from the Santa Cruz Mountains unlike 

 any which either he or I had seen before, which he believed to 

 be new, and I could not gainsay it. He therefore soon after 

 published it as C. Andersonii, dedicating it to our friend Dr. 0. 

 L. Anderson, of Santa Cruz. I adopted the species readily in 

 the Flora Franciscana, without any critical study of it ; nor did 

 I doubt its validity until, at Kew Gardens in 1894, while 

 examining types in this genus, I discovered that the originals of 

 Hooker and Arnotts' C. integerrimus were precisely what Dr. 

 Parry had published as new under the name C. Andersonii. 



Consulting the original description by Hooker, we find that 

 that alone, duly regarded, would have saved both Dr. Parry and 

 myself this error; for the leaves are described as "oblong-ellip- 

 tical," a character which the foliage of the common shrub of 

 the mountains of the interior never exhibits, its leaves every- 

 where showing something of the ovate in outline ; being even 

 very commonly ovate.
