1922.] REVISION OF CALIFORNIA ARCTOSTAPHYLI S3 



lumne Co. Definite stations in the Sierra Nevada are now for the 

 first time indicated. 



The binomial Arctostaphylos manzanita has been made to do 

 duty over too wide a range; indeed it has been applied to other 

 species in all parts of California. It is, however, one of the most 

 definite of our manzanitas and is as yet known only from the foot- 

 hills of the North Coast Ranges towards the interior and the 

 Sierra foothills from Tuolumne Co. northward. It also occurs 

 locally on Mt. Diablo.

9. A. pastillosa Jepson n. sp. In the higher foothills of the 

 Sierra Nevada a manzanita occurs in a belt between that of A. 

 viscida below and A. patula above. It is a vigorous shrub and has 

 large berries which in shape and often in hue suggest the loaves of 

 bread seen in bake-shops in Italy. It ranges from Placer Co. to 

 Tulare Co. The formal diagnosis appears below. 



Locs. — Cold Spr., North Fork Tule River, Jepson 4704; Straw- 

 berry, Tuolumne Co., A. L. Grant 888; Cold Spr., Tuolumne Co., 

 Jepson 6456 (type); Bald Mt. near Sonora, A. L. Grant 666, 553; 

 Yankee Hill near Columbia, A. L. Grant 598; Shingle Sprs., F. B. 

 Herbert. 



A. meukka Merriam, Proc. Biol. Soc. Wash. 31:101 (1918), 

 type loc. ridge between North Fork American and Bear Rivers above 

 Colfax, Merriam. The life history of this species is too insufficiently 

 described to be placed with certainty in this series as here arranged. 

 The specific name, borrowed from the Miwok tribe, seems bar- 

 barous. Dr. Johnson once said, however, that no language is bar- 

 barous to the person to whom it is native. Dr. Merriam has cul- 

 tivated Indian lore and tribal habits so long that meukka to him is 

 probably as pleasing as the lucent phrases of the Ars Poetica to the 

 ear of Horace.
