78 ' — PITTONIA. 
petiole, but scarcely marking a distinct node, an occasional 
peduncle leafless and scape-like: sepals 6 to 10, oblong-linear, 
commonly quite unequal: filaments elongated and narrowly 
linear: carpels 6 to 10, rather thick, substipitate. : 
À beautiful species, well marked as such, though holding 
an intermediate place between the two groups herein out- 
lined; only the smallest specimens presenting the solitary 
two-flowered peduncle; all the larger exhibiting several 
stems, one of which is one-flowered and bractless. The 
British Columbian specimens collected by Mr. Macoun are 
numbered as follows: n. 1,255, from along streams at 6,000 
feet on Mt. Queest, 28 July, 1889; n.1,2506, obtained in alpine 
swamps at 5,500 feet on Mt. Arrowsmith, Vancouver Island, 
17 Julv, 1887: and n. 1,257, collected near the snow line in 
the Selkirk Mountains, 20 Aug., 1885. 
I also locate here a number of specimens in the U. S. 
Herbarium, which are from about the same geographical 
region within the U.S. boundaries. One from Mt. Rainier, 
at 6,500 feet, collected by Mr. C. V. Piper in August, 1895. 
There is another from Cougar Peak, Oregon, by Coville and 
Leiberg, 1896. This is in fruit, and all the foliage is quite 
entire. A third is “from beyond Florence, Idaho,” L. F. 
Henderson. This specimen exhibits large leaves quite defi- 
nitely crenate, and one stem has three flowers, with a pair of 
leaves subtending the peduncles. Yet another, Sandberg 
and Leiberg’s n. 723 (1896), from Stevens’ Pass in the Cas- 
cades, has four peduncles, each axillary to a bract of its own. 
The filaments in all these U. S. specimens, as in the more 
northerly ones, are so much compressed that they are linear 
rather than filiform. m 
C. cHELIDONII Dwarf, the largest 4 inches high, others 
2 or 3 inches; herbage very dark-green: leaves all round- 
cordate with open sinus, acutish, slightly, and for their size 
rather remotely, crenate, mostly less than an inch long,
