ser 
duced the present plant were brought to the Horticultural] 
Society, by Mr. David Douglas, in 1824. Perhaps it has 
been confounded with either Z. scariosa or sguarrosa, from 
both which it is certainly distinguished by its humble 
growth and long narrow leaves. From LZ. scariosa it differs 
in its dwarf panicled stem and turbinate involucra, with 
acute pungent leaflets; from L. squarrosa, also, in the form 
of its involucra, in the totally different disposition of: the 
leaflets of that part, and in an abundance of other particu- 
lars. To the various spiked species from L. macrostachya, 
to the elegant L. sphéroidea, it bears very little resemblance. 
L. gracilis of Pursh, said to be a variety of L. pilosa, which 
we cannot believe, has small round heads of flowers, with 
blunt leaflets, and not turbinate heads with pungent 
leaflets. 
_ A hardy, perennial plant, flowering in August and 
September. Our drawing was made in the Chiswick 
garden, in 1824, 
Root tuberous. Stem 1 to 14 foot high, panicled, an- 
gular, a little hairy, somewhat corymbose. Lower /eaves 
grassy, smooth, hard-edged, roughish to the touch, obso- 
letely 3-nerved; upper are shorter. Jnvolucres terminal, 
at the end of the branchlets, turbinate, many-flowered ; 
leaflets imbricated acute: inner membranous; outer larger, 
somewhat leafy, pungent, ciliated, not squarrose. orets 
under a magnifying glass very slightly silky. Ovarium 
obovate, striated, hairy. Pappus beautifully feathery.
