In “ Das Pflanzenreich" Buchenau takes up the name var. aemulans 
for this variety, based on the J. aemulans of Liebmann (in Vidensk. 
Meddel. nat. For. Kjóbenh. 38, 1850). Liebmann’s description was 
based, however, on material from southern Mexico, and since we have 
seen no material of the present variety from that region, so far dis- 
connected from its usual range, it seems unwise, without further 
knowledge of Liebmann's plant, to treat it as identical with var. 
brunneus Engelm. This variety and var. gracilis both have the same 
dark-colored perianth of similar rather soft texture, but may easily be 
distinguished by the basal sheaths. From var. compactus, which has 
been found on Vancouver Island, var. brunneus is quickly distinguished 
by its slender habit, darker flowers, and more slender and attenuate 
perianth-segments and prophylla. 
Var. pacificus n. var., caulibus crassis 6-13 dm. altis 2-3.5 mm. 
diametro rigidis obscure multi-striatis; cataphyllis basilariis castaneis 
opacis chartaceis, supremis 6-15 cm. longis, marginibus fere ad api- 
cem subtruncatum vel emarginatum arctissime imbric ato-convolutis, 
venis ad apicem valde convergentibus; inflorescentia plerumque laxe 
fastigiata 2.5-15 cm. longa; bractea infima 6-20 cm. longa; sepalis 
2.7-3.5 mm. longis submollibus quam petalis vix longioribus, dorso 
fulvo-viridibus gracilibus, marginibus fulvis scariosis; petalis simili- 
bus; capsulis perianthium vix aequantibus.
