pureo, 1—2 dm alius; anternodi vel longiores vel breviores vel aequales 



foliis. Folia marginlbus scabris hon vestita, basilaria spatulata; cauiina 



lariceolato-linearia, in caule inferiore late lanceolata et paulo falcata- 



Flores in axillis foliorum aut solitarii aut per ramos breves folio non 



longiores conspersi, ramo singulo 2 usque 5 flores gerente, quorum 



proxlmi pedicellos 5— 10 mm longos, remoti pedicellos 2 vel 3 mm 



lotigos habent; Tubus calycis 2 mm longus, lobi ejus 4 vel 5, inaequales, 



3 — 4 ram Ipngi, lineares, longiores quidem tube coroUae compares. Co-. 



rolla 6—8 mm longa, tubulata, 4—5 lobata, colore lilacino (vel lobi 



lilacini, tubus autem roseus), lobi 3x2 mm diametris, corona paucis 



vel nuUis setis vesiita. Segmenta corollae ovata, obtusa, soli late apertA. 



Siliqua teres, sessilis, matura lobos calycis nonnihil excedens. — ^ In 



order not to mistake this species for Aynarella acuta (Michx,), it has to 



be remembered, that the latter has minutely scabrous leaf margins, 



flowers 10 — 16 mm long, calyx almost 5-parted and its lobes lanceolate, 



and the corolla blue with acute, lanceolate lobes. — North Dakota: 



This species is only to be found near springs and is so attractive to 



horses, that it is difficult, where they can reach them, to collect plants 



with entire stems. Horses do not touch the other gentianeae growing in 



the same pasture as this. It was disoovered by Miss Gurli Lunell 



on August 28, 1911, at Butte, Benson County, and was named in her 

 honor. ^ . / ,. t ' : , : -

1062. Amarella theiantha J. Lunell, 1. c„ p. 143. — Planta annua. 

 Caulis fere simplex vel modice vel effuse de basi ramosus, teres vel 

 angulatus vel leviter quoque aeque cum ramis alatus, flavus, strictus, 

 1—4,5 dm altus, internodi in plantis' maioribus circiter 4,5 cm longi. 

 Folia basilaria ovalia vel spatulata, plerumque mortua vel languescentia, 

 cauiina media vel oblonga vel lanceolata, basl lata et apicem versus 

 sensim angustata, internodiis multo breviora, summa mensura reducta, 

 forma autem aequalia. Flores in axillis foliorum aut solitarii aut in 

 ramis brevibus 2 — 4, pauci quidem in plantis subsimplicibus, sed in 

 plantis luxuriosis propter ramos earum fastigiatos nimios valde nuraerosi. 

 Pedicelli 0,5-2 cm longi. Lobi calycis 4 sive 5, longitudine admodum 

 inaequales vel ferme aequales, quorum 2 latiores et 2 vel 3 angustiores 

 et tubo corollae aut aequales aut multo breviores sunt. Corolla 10 

 12 mm longa, 4— 5-lobata, extremitates versus attenuata, colore candide 

 sulfureo, lobis semper clausis, acutis, 2,5.x 2 mm diametris, basi iim- 

 briarum setacearum nulla corona vestitis, nisi forte setae binae unum 

 vel plures lobos adornant. ~ Related to this species are A, scoptdorum 

 Greene and A. plebeia (Cham.). Greene which are 1 — 3 dm high, with 

 internodes in larger plants 2,5— 7,5 cm long, shorter sepals, blue flowers 

 and deeply fringed appendages; and A. striciiflora (Rydb.). Greene with 

 leaves equalling or surpassing the internodes, with a dense and spike-, 

 like inflorescence, and with numerous, crowded, almost sessile flowers-
