Thickets &;c. Canada! to Florida! west to Indiana! and Missouri! 

 May-June. — Stem 10-20 feet liigh. Spines often 2-3 inches long, sharp 

 and rather slender. Leaves usually obtuse, paler and dull beneath. Seg- 

 ments of the calyx linear-lanceolate, rather shorter than the petals, occasion- 

 ally glandular-sen^ate, as are nearly all the species. — The varieties 6. & r. 

 which we only know from cultivated specimens, are somewhat peculiar ; but 

 we have apparently intermediate indigenous forms. — CocTc-spur TJiorn. 



3. C. rivularis (Nutt. I mss.) : " arborescent, nearly glabrous ; leaves 

 ovate or obovate, obtuse or sometimes acute, simply or somewhat incisely 

 serrate, attenuate into a short petiole ; spines long ; corymb many-flowered, 

 glabrous ; flowers small ; segments of the calyx obtuse and very short, not 

 glandular ; fruit black." 



Oregon, along rivulets in the Rocky Mountains, Nuttall ! Interior of Ore- 

 gon, Douglas ! — We have good specimens of this apparently very distinct 

 species from Douglas's collection. The leaves are, as Mr. Nuttall remarks, 

 " about as entire as those of the Apple," to which they bear some resem- 

 blance, serrate with short and broad teeth, sometimes a little incised toward 

 the apex, mostly obtuse, shining and minutely pubescent on the upper sur- 

 face. The young branches are reddish-brown. We have only seen the 

 very young fruit. 



4. C. sanguinea (Pallas) : leaves broadly obovate, somewhat cuneate at 

 the base, incised and serrate, often slightly 5-7-lobed, a little pubescent when 

 young, on short petioles, at length coriaceous and shining ; corymbs glabrous 

 or somewhat pubescent ; segments of the calyx entire, and, as also tlie pedi- 

 cels, not glandular; styles 3-4; fruit globose. — Pall. Jl. Ross. 1. j^- 25, t.

Banks of streams (/?.) Oregon, Douglas ! Nuttall ! — A small tree, with 

 reddish branchlets. — The Oregon plant agrees well with our specimen of 

 C. sanguinea, Pall, from Altaic Siberia, from which we have dra\\Ti the 

 character here given. Not having access to the work of Pallas, we know
