already 0.0 line long; Dr. Hooker (Bot. Antarct. Voy. FI. 
Tasm. 2, 64) speaks of the seed of this species as “linear- 
oblong, striate, with the testa produced beyond either end,” 
and as the Tasmanian plant* has very different seeds, his 
remark must refer to the Californian species. 
Hooker & Arnott, Bot. Beechey, p. 402, distinguish from 
the original J. Menziesii , with obtuse sepals, the variety 
Californicus , with acuminate ones; I have found, in all the 
specimens, examined by me, the outer sepals acuminate and 
the inner ones obtuse, with or without a mucro; but in some, 
as stated before, the outer ones are much shorter than, in 
others as long as, fhe inner ones. 
29. J. longistylis, Torrey in Bot. Mex. Bound, p. 228: 
caulibus (pedalibus bipedalibus) csespitosis stoloniferis tereti- 
usculis sursum ssepius (sub lente) scabriusculis foliatis; foliis 
planis gramineis; capitulis paucis in paniculam contractam 
aggregatis seu raro singulis; floribus (majoribus viridulis 
fusco-striatis) lsevibus pedicellatis; sepalis sequalibus ovato- 
lanceolatis acutatis seu cuspidatis stamina 6 duplo superanti¬ 
bus; antheris filamento sub-duplo longioribus; ovario stami¬ 
na et stylum sequante, stigmatibus exsertis; capsula ovata 
obtusa mueronata seu rostrata castanea nitida triloculari 
calycem aequante seu paulo superante; seminibus oblanceo- 
latis seu obovatis apiculatis cosrtato-reticulatis.— J, Menziesii , 
Gray in PI. Parry, p. 34, and Pl. Hall & Harb. p. 77, “the 
yslt. Californicus, Hook & Arn., probably an unpublished 
• species.” 
Rocky Mountains from Hew Mexico, Wright 1924, Fendler 
857, to Fort Whipple, Arizona, Cones & Palmer f 48, and 
northward to Colorado, Parry 681, Hall Harb. 566, to the 
Saskatchewan, Pourgeau , and towards Oregon, Lyall .— 
Stems cespitose, or, probably in richer soil, stoloniferous, 1-2 
feet high; panicle usually li-2^ or 3 inches long, consisting 
of 5-9 heads; heads 3-8 or 12-flowered, sometimes fewer or 
single, and then 12-15-flowered; flowers 2^-3 lines long; 
* The Tasmanian J. falccttus, Hook. f. 1. c., of which I find a good 
specimen with ripe fruit, collected by Gunn, in Hb. Gray, is certainly 
very similar, but seems to be distinguished by smaller but also scabrous 
flowers ; ovate, retuse capsules of the length of the equal, acutish sepals; 
and obovate, obtuse, abruptly apiculate reticulate seeds, the area© of which 
are perpendicularly lineolate ; it might be distinguished by the name of J. 
Tasmanicus. 
| While this sheet was in the hands of the printer I received a most 
interesting collection of Arizona Plants, made last year by Drs. Elliott 
Coues, and Edward Palmer, in which I found good specimens of this 
species, and also some of J. compressus, unfortunately again without fruit; 
the leaves of this last, however, are finely developed, thus adding another 
proof for the opinion, that it is really a regularly leaf-bearing species.
