igoi] Holm — Canadian Species of Gentiana. i8i 



Collected by Prof. John Macoun in low, moist ground near 

 Salt Lake, Anticosti Island, Quebec ; with flowers in August, 1883. 

 The only known locality for this species. 



These are the species which have been collected in Canada, 



and which were formerly supposed to represent Gunner's G. serrata. 



They are all very different from the plant we collected in the Rocky 



Mountains of Colorado, and of which we have, also, received 



some specimens from Wyoming through the kindness of Professor 



A. Nelson, who someiyears ago described it as G. elegans. It is 



more than probable that this species occurs, also, in the British 



provinces, thus we take the opportunity of presenting a diagnosis 



and an illustration of this excellent species in connection with the 



Canadian. 



Gentiana elegans A. Nels. ^ ^ 



(Plate XIV, Fig-s. 7 and 8.) 



Annual, glabrous excepting the calyx, very robust : stem 



erect, angled, 20 to 40 cm. in height, branched from near the 



base : leaves forming a rosette, broadly spathulate, the upper 



lanceolate, obtuse : peduncles often numerous, until 20, erect, 



i-flowered : calyx pale green with purple spots, about 3 cm. long, 



unequally cleft to the middle or below, the longer lobes narrower 



than the others, all with membranaceous margins and very sharp 



and prominent keels, scabrous only along the keels : corolla (figs. 



N and O) bluish to deep purplish, until 5 cm. in length, 4-lobed, 



the lobes very broad and veiny, erose across the summit, fringed 



along the sides : nectariferous glands 4 : stamens 4, the filaments 



broadly winged, the anthers as in the preceding species at first 



introrse (fig. O), but later on extrorse (fig. N) : ovary (fig. P) 



stipitate, the style distinct, but short, stigma (fig. Q) roundish and 



4-lobed: mature capsule shorter than the corolla: seeds with 



short, obtuse papilla;. 



Collected in Wyoming at 9 — io,ooo feet elevation and in 



Middle Colorado near Long's peak at 8,600 feet, where it grew 



abundantly in meadows in the Aspen Zone, with flowers in August. 



It has, furthermore, been collected in Southern Colorado near 



Pagosa peak at 11,000 feet.
