A herbario Grayano (Cambridge, Massachusetts) photographiain deminutam speeiminis 

 authentici J. monostichi Baitlett aeeepi. Similis est Junco tcnni var. Williamsii Fernald; in- 

 (lorescentia drepana nonnulla praebet: 3- usque 7- (raro 8-!)flora, ergo ad J. seeundum attinet. 

 Melius inquirendus remanet. Descriptioneni autoris addo (Rhodora VII. (1905) 50):

 tudinally oblong, 2 — 2 1 /2 times as long as broad.« 



»It was found to be closely related to Juncus dichotomus and Jiincus secundus, but differred 

 from both in its very small capsules, long basal leaves and large, longitudinally reticulate seeds«.

»Stern 17 — 25 cm high, a little over 1 mm broad. Leaf blades 4 — 5 cm long, 

 about 1 mm broad. Head 1,3 — 2 cm broad, about 1 2-flowered; lowest bract gener-

»The inflorescence recalls J. leucanthus Royle, from which, however, it is at once 

 distinguished by the absence of the cauline leaf. The species is near J. Thomsoni 

 Buchenau but is a much more robust plant«.
