Nota. J. xiphioides, ensifolius, alatus et oxymeris gregem polymorphum formant, adhuc 

 non satis explanatum; formae in natura melius observandae!

 120 cm alti; folia iridacea, usque 6 mm lata; vaginae inauriculatae vel truncatae. In-

 Caules humiliores, 20 usque 50 cm alti, angustiores; folia angusliora; vaginae saepe 

 truncatae. Inflorescentia minus composita; capitula plerumque pauca, pluri- usque multi-

In den Gebirgsgegenden des westlichen Nordamerika weit verbreitet, landeinwärts

Var. e. triandrus Engelm. 1. c. (1868) 4 82 — meä opinione pr. pte. ad var. 

 montanum, pr. pte. ad J. ensifolium pertinet. 



Nota. Varr. montanus, macranthus et triandrus melius inquirendae sunt, Ccl. Engelm. 

 sub var. montano varietates (?) duas diversas laudat: »capitulis pauci- (3- usque 1 0-)floris, palli- 

 dioribus, pluribus, paniculatis seu paucis (raro singulis), pluri- (12- usque 20-) vel multi- (20- us- 

 que 50-)floris, fuscis«. 



Nota. Rydberg in Bull. Torr. Bot. Club XXXI. (1904) 400, var. montanum Engelm. in 

 species tres dividit: 



J. saximontanus Nelson. — Auriculae parvae semper adsunt. Capitula pauca, magna, 

 intense colorata, fusca. — Von Alberta und Britisch-Columbien bis Colorado und California. 



J. brunnescens Rydberg. — Margines vaginarum truncatae, sed non auriculatae. Inflores- 

 centia aperta; capitula 10 usque 60, parva, 5- usque 12-flora, pallide fusca; tepala subaequi- 

 longa, lanceolata, acuminata, pallide fusca, medio dorsi viridiuscula; stamina plerumque 6; stilus 

 tepalis fere aequilongus. — Colorado (Baker n. 245); Neu-Mexiko (Rusby n. 4I7 C , 41 7 D , 

 417^); Arizona (Flagstaff n. 1898, Mac Dougal n. 304, Toumey n. 6; Means; Rusby 

 n. 417A, 417E). 



J. parous**) Rydberg. — Margines vaginarum sensim attenuatae, nee truncatae. Inflores- 

 centia minor; capitula \ usque 8, saepe aggregata, 15- usque 20-flora; tepala lanceolata, »sharply 

 acuminate«, pallide fusca sive dorso viridiuscula; stamina plerumque 6; stilus tepalis brevior. — 

 Colorado (Shear n. 3666, 3668, Bessey n. 1895, 1896); New Mexico (Wooton n. 615). 



*) »As there is a variety montanus of J. balticus, this plant, which seems well to deserve 

 specific rank as well as a separate uame within the genus, may take the above as indicating 

 its center of distribution« Av. Nelson. — Ein schlagendes Beispiel für die von manchen Ameri- 

 kanern jetzt beliebte Handhabung der trinomialen Nomenklatur!
