RYDBERG: STUDIES ON THE RocKy MOUNTAIN FLORA 465 
Swertia Fritillaria Rydb. 
Glabrous, light green, perennial; stem 1.5-3 dm. high; basal 
leaves and lower stem-leaves alternate, 6-10 cm. long, thin, long- 
petioled; blades obovate, spatulate, rounded at the apex, abruptly 
contracted into winged petioles of about the same length; middle 
and upper stem-leaves all alternate or a single pair of opposite 
ones, oblanceolate or oblong; inflorescence rather lax, elongate; 
pedicels 1-2 cm. long; sepals lanceolate, about 6 mm. long; 
corolla-lobes lanceolate, mostly acute, greenish white along the 
midrib and azure along the margins, dotted all over with dark 
blue spots in the manner of many species of Fritillaria; filaments 
more or less dilated, some of them very broad; glands inconspicu- 
ous with rather long blue fringes.

APOCYNACEAE 
. Amsonia Eastwoodiana Rydb. sp. nov. 
Perennial, with a short woody base; stem 3-5 dm. high, gla- 
brous; stem-leaves lanceolate, usually narrowly so, 3-5 cm. long, 
glabrous, acute at each end; leaves of the numerous strongly 
ascending branches linear; calyx-lobes subulate, 2 mm. long or 
longer; corolla 16-20 mm. long; tube narrowly trumpet-shaped; 
lobes nearly 4 mm. long; pod 5-8 cm. long, about 8 mm. thick, 
constricted and often breaking off between the seeds, 3—5-seeded; 
seeds oblong, about 1 cm. long and 6 mm. thick. 
This is most closely related to A. brevifolia, having the same 
flower and fruit, but the plant is in habit more like A. Fremontii, 
for which it has been mistaken. The latter has still longer 
calyx-lobes which are narrower, and its pod is not restricted 
between the seeds. In canyons of desert regions.
