Farr on British Columbian Planis. 423 
Pachystima macrophylla, sp. nov—Cork tissue brown or 
with a thin brownish-black external layer. Cortex abund- 
antly provided with conglomerate crystal cells, strong strands 
of sclerenchyma in the colloid layer of the cortex and small 
strands in the inner cortex. Wood open, porous, with rela- 
tively large pitted vessels. Pith relatively small, the central 
pith cells moderately thickened with punctations; starch 
rare or absent in these. Leaves with lower epidermal cells 
of larger size and more strongly sinuous walls than in 
Myrsinttes, the stomata one-third fewer, sclerenchyma strand 
two to three times larger, leaf below the midrib strongly 
swollen and the epidermal cells expanded into papillae. 
Cornus Canadensis, L. var. intermedia, var. nov.—Stems 
5 to 7 inches high, usually simple, rarely branched, woody 
at base, from a creeping, horizontal rhizome. Leaves either 
mostly verticillate, two to six at the summit of the stem, 
with two much smaller leaves and scale-like bracts below, 
or occasionally borne in pairs, nearly sessile, oval, ovate 
or obovate, acute at each end, or sometimes rounded at base, 
entire, glabrous or minutely appressed-pubescent, with two 
much smaller leaves and scale-like bracts below. Flowers 
purple, capitate, subtended by four involucral bracts, 4 to 9 
lines long, ovate, white, petaloid, somewhat unequal; borne 
on slender peduncles 6 to 18 lines long. Petals white with 
purple tips, ovate, one of them with a subulate appendage 
at apex. Stamens alternate with petals. Styles much 
exserted, deep purple, giving a dark appearance to the flower. 
Fruit about 2 to 4 lines in diameter, globular, bright red, 
appressed-pubescent, one-seeded, seeds ridged on either side. 
Glacier, flowering specimens, July 5 and August 12, 1904; 
fruiting specimens, August 22, 1904. 
Specimens of the above Cornus were gathered during the 
past summer at Glacier, which alike from study of fresh 
material in the field and detailed laboratory examination has 
proved a puzzling form. It seems in combination of charac- 
ters to unite to a remarkable degree the specific characters of
