STUDIES IN CEANOTHUS. 21 7 



eosus of the table lands of southern California and of the peninsula is 

 like it in this respect. But C. connivens is nearly prostrate through mere 

 lack of firmness or hardness in wood fibre. It, however, evinces none of 

 the rooting and matted character of the not yet well-described but most 

 distinct G. prostratus.— Along the bleak summits of the Siskiyou Mount- 

 ains of southern Oregon I observed in September a Ceanothus much like 

 this in leaf character; the stems depressed but not prostrate, less flexible 

 and stouter. In the absence of fruit, one could not say whether it could 

 be referred to this or whether it would be a stunted growth of C. cuneatus 

 with truncate and notched leaves. The zeal and diligence of Mr. Howell, 

 who has easier access to the region indicated, it is to be hoped may settle 

 the question by collecting it in fruit some day.— E. L. Greene in Pitt., ii, 

 16 (Nov., 1889). 



Ceanothus pumllus. A rigid depressed much branched evergreen under- 

 shrub, the branches often rooting at the joints and from a few inches to 

 a foot or more in length: leaves opposite, very small (3 to 5 lines long), 

 rigidly coriaceous, glabrous above, very minutely white-tomentose between 

 the veins beneath; entire except at the usually 3-toothed apex, the general 

 outline from oblanceolate to obovate-oblong: flowers in numerous sessile 

 umbels, rather pale blue: fruit unknown.— On hillsides near Waldo, Oregon, 

 April 1892, Thomas Howell.— E. L. Greene in Erythea i, 149 (July, 1893). 



III. Hybrids of Euceanothns zvith Cerastes. 



These are very rare. Only two have been observed and 

 neither has been found a second time. Neither of them 

 appear to set fruit. The first is almost certainly a hybrid 

 of C. thyrsi-florns and C. rigid/is. The second is without 

 doubt a cross between C. vchitiniis and C. frostratus. 

 Only one plant has been seen and the discoverer reports 

 that it flowers very sparingly and does not fruit at all. 

 Examination of the flowers shows that the pistils are dis- 

 torted. Prof. Greene considered C. cuneatus to be one 

 of the parents, which is practically impossible, as that 

 species does not occur within thirty miles of the locality.
