496 TRANS. OF THE ACAD. OF SCIENCE. 



large tufts, 2-3 feet in diameter, on the sandy banks of stream- 

 lets, alt. 6,500 feet, H. Bolander, fl. in July. — In many re- 

 spects intermediate between the foregoing and the following 

 species, this plant is distinguished from both by its small ob- 

 tuse flowers, green with light brown margins (1^, or in fruit 

 nearly 2, lines long), the elongated obtuse capsule, and above 

 all by the distinctly reticulated almost obtuse seeds, which 

 in both others are more or less pointed or even tailed and 

 differently marked ; the seeds, I could examine, not quite ma- 

 ture, are 0.25 line long and half as much in diameter, and ex- 

 hibit 8 ribs on one side; their areas are apparently smooth. 



J. lonctistylis also on the Red River of the North, Hub- 

 bard in Hb. Lapham ; Huerfano Valley of the Rocky Moun- 

 tains, Parry ; on the banks of Mono lake in the Californian 

 mountains, Bolander, Hb. n. 43. — Stem with several short 

 leaves, always considerably exceeding the linear foliage ; 

 seeds apiculate or short tail-pointed, with a distinct white 

 raphe, strongly ribbed, when not perfectly mature, like those 

 of J. marginatus; fully ripe seeds with very slight cross-bars 

 and a faint transverse lineolation. 



Var.? latifolius: caule erecto (pedali) nudo seu basi uni- 

 foliato, folia brevia lineari-lanceolata longe excedente; pani- 

 cula simplici spatha membranacea rare foliacea longiori ; ca- 

 pitulis pauci- (3-5-)floris ; antheria longe liuearibus filamento 

 triplo quadruplo longioribus ; seminibus obovatis costato-sub- 

 reticulatis. 



Californian Sierras on alpine meadows or along rivulets in 

 the Yosemite Valley, alt. 4,000 feet, Hb. n. 40 ; on the upper 

 Tuolumne, alt. 10,000 feet, and frequent on the eastern slope 

 of the mountains, II. Bolander. — Easily recognized by its 

 broad (2-3 lines wide) and short (2-4 rarely 5 inches long) 

 light green leaves, few-flowered heads and long anthers, but 

 probably not specifically distinct; seeds 0.25-0.30 line long, 

 reticulate with faint cross-bars, areae slightly lineolate or al- 

 most smooth; 7 or 8 ribs visible. 



Pag. 454. J. leptocaulis ; the Arkansas specimens have 

 been collected by Dr. Leavenworth ; for the Texan localities 

 credit is also due to that ardent old gentleman, Dr. Gideon 

 Lincecum, who, in his 79th year, still continues an active 

 botanist, and is now seeking a new field in Mexico. — Mr. 

 Buckley protests against the change of his and the restora- 

 tion of an older manuscript name, and threatens to lay the 

 matter before the public for arbitration, in which I wish to 

 assist him, referring only to the remarks on page 454. 



J. marginatus; var. paucicapitatus ought to follow var. 

 vulgaris,' both are distinguished from the other variety by a 

 more slender growth, meagre panicle, and mostly smooth 

 edges of the leaves; in Herb. norm, only gracile forms are 

 represented, 33 Pennsylvania, Porter; 34 West Canada,
