Pachystima niacrophylla, 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 

 Myrsinites, 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. 



C omits 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
