THE GENUS ACT.1:A. 109 



cluster, as many as five or six proceediDg from a single clump 

 of roots. Tlie base of the stem is enclosed within several 

 sheath-like rudiments of leaves, the one or two leaves appear- 

 ing above midway ; and, as compared with other members of 

 the genus whose flowering is known to me, the leaves are less 

 developed at time of flowering, and that is as late as June 

 and even July, which is very late in northern Arizona. The 

 raceme of greenish flowers is particularly narrow, elongated 

 and dense. In fruit it is commonly five or six inches long ; 

 and while all the pedicels are short, those at base of the 

 raceme are scarcely longer than those which are uppermost. 

 The petals are rather numerous, the blade varying from ovate 

 to nearly lanceolate, usually acutish, the whole petal being 

 but little shorter than the remarkably short greenish stamens. 

 The habitat of this Adcea is in open rocky places among 

 the pine and spruce woods of Mt. San Francisco, Arizona. 

 It was collected, barely in flower, by the writer, July 10, 1889, 

 and some years before by Dr. H. H. Eusby, whose specimens 

 were in immature fruit. The ripe berries are unknown. 



Notes on Ranunculus. 



On pages 59 and 60 preceding, my attempt to bring order 

 out of the then existing confusion of some Arizona species 

 was only half successful. I have since learned that I was 

 still in error about the type of what Dr. Gray, on Mr. 

 Lemraon's behalf, had published as B. Arizonicus. That is 

 a plant of the Huachuca Mountains, far to the southward of 

 Mt. San Francisco ; and I Lad never seen it, up to the time 

 when the paragraphs I am now citing were wTitten. True 

 R. Arizonicus neither occurs in northern Arizona, nor has it 

 ever been collected or distributed by me.
