182 PITTONIA. 
‘G. INTERRUPTA. Allied to G. affinis, taller, erect, 1 to 14 
feet high, glabrous, rather densely leafy near the base, 
otherwise with scanty foliage, the upper pairs of leaves of 
less than half the length of the internodes; lowest leaves 
oblong or elliptic-oblong, the others oblong-linear, all some- 
what widely spreading, rather small, the longest barely 1 
inch long: inflorescence sparse and elongated, the more or 
less remote upper nodes bearing each a pair of erect pedun- 
cles 1 to 2 inches long, bracted at summit and with 1 to 3 
flowers: calyx with narrowly turbinate tube subscarious 
below the sinuses, and short unequal herbaceous teeth, 
these linear or subulate-linear: purple-blue corolla small 
and narrow, the largest barely 1 inch long; short lobes 
ovate, acutish; folds very short, setaceously cleft. 
In meadows along streams at Pagosa Springs, southern 
Colorado, 30 Aug., 1899, C. F. Baker. Remarkable among 
gentians of this group for the long and notably inter- 
rupted inflorescence. 
f G. REMOTA. Size and habit of the last, with similar 
foliage and almost equally interrupted inflorescence, but 
the flowers few, solitary both terminally and as to the 
axillary peduncles: calyx-tube narrowly turbinate, herba- 
ceous, as also the oblong equal teeth or segments, these 
almost as long as the tube: corolla expanding and funnel- 
form, with very short, broadly obovate abruptly acute lobes 
and very short lacerate folds. 
Meadows of the Humboldt River at Deeth, Nevada, 
scarce ; collected only by the writer, 5 August, 1895. 
' G. pisreeia. Annual, from a few inches to more than a 
foot high, mostly simple, with few pairs of leaves and long 
internodes and flowers in all the axils except the very basal 
ones, these either solitary and very long-peduncled, or else
