their length, parted to or below the middle, recurved; stigmas 



slightly capitate. 



Youiig fruit strongly glandular hairy, but never prickly, becoming 

 smoother with age; mature fruit maroon or reddish-parpk^, globose, 

 three-eightbs of an inch in diameter, few to many-seeded, edible; 

 seeds distinctly wing-margined, with the inner coat, as seen through 

 the gelatinous covering, longitudinally dotted. 



It will be seen that this plant ai)proaches both B.gJutinosnm^ Benth., 

 and B. smtguineum, Pursh., though its nearer affinity is with tlie latter. 

 It is distinguished from the former in being fewer-flowered, having 

 shorter racemes, and a ronnder berry; and from the latter by its 

 shorter racemes, relatively shorter bracts and longer pedicels, and 

 erect calyx-lobes. It may prove to be a mere variety of R. sanguineiim, 

 though i think it sufiicientiy distinct to bear the name of its zealous 

 discoverer, Professor Wolf.

E. LATiFOLiUM, L. Twiu Lakes. Altitude, 9,600 feet. Wet, rocky 

 places. August. We have in the collection the extreme forms of 

 broadly-lanceolate and narrow, lanceolate-linear leaves, with all 

 gradations between. (142.) 



E. TETRAGONUM, L. Twin Lakes. July. Altitude, 9,000 feet. (145, 

 153, 154, 156.) The form 154 is a fair E. coloratum^ Muhl. ; but I 

 am heartily in accord with Mr. Watsou in nuiting both under the 

 same sjiecies. From the abundant nuiterial at iny command, I cannot 

 assign a specific distinction to their points of contact. 



B, PALUSTRE, L-, var. ^. aluiflokum, in T. & G. (156 his.) These 

 specimens were intermixed with 156 in the retained collection. So plaiidy 

 marked were their characteristics; L <?., leaves entire, lance-linear, 

 obtuse, stem few-flowered, flowers almost white, capsule hoary, at 

 first almost sessile, afterward with a long pedicel, that I am half 

 inclined to keep the form distinct as a species. Except for its mani- 

 festing little or no tendency to branch, it would be exactly E. rosma-
