NEW SPECIES OF LACINIARIA. 315 
ing racemes elongated and lax, and growing ovaries notably 
stipitate. 
Described from specimens obtained by the writer in the 
mountains near Tehachapi, California, 22 June, 1889. It 
has also been permitted to pass for T. integrifolium, though 
seen to be remarkably distinct when compared with the 
original of that species, which is from the remote interior, 
toward the sources of the Columbia River. 
New SPECIES OF LACINIARIA. 
^L. virrata. Stem 2 feet high, from a narrow fibrous- 
coated tuberous root; herbage glabrous: leaves nearly all 
from below midway of the stem, lance-linear, ascending or 
suberect, the longest nearly a foot long, plane, the lowest 
and broadest channelled beneath between each pair of the 
five prominent elevated parallel veins: spike 4 to 7 inches 
long, on an almost naked (merely small-bracted) peduncle: 
heads subeylindric, only about 4 lines long, crowded; bracts 
of involuere about 20 and closely imbricated, oval to oblong 
or obovate-oblong, 5-7-striate up to near the rounded nar- 
rowly scarious-margined and erose-ciliolate tips: flowers 5 
to 7: achenes hirsutulous; pappus subplumose.. 
Near Biloxi, Mississippi, 19 Sept., 1898, S. M. Tracy (n. 
6350 of my set of Tracy's plants) This was distributed, by 
my advice, as L. spicata; but it is a most distinct species, 
allied to the northern L. pycnostachya. It is remarkable for 
its long ribbon-like glabrous channelled foliage. 
Y L. SEROTINA. Rather slender, 2 feet high or less, the 
stem hirsute or almost tomentose with white more or less
